In Praise of Ferns (western North America) - photos by Connie Barlow

ghostsofevolution 2023-09-12 | This 13-minute video entails 110 of Connie Barlow's best photos of ferns living under (and on) California's inspiring Coast Redwood trees. Using the smooth movement of, what has come to be called, the Ken Burns effect creates a gentle dynamic and flow that is ideal for experiencing a variety of fern species in their glory. Recommendation: turn down the audio scrollbar at the bottom left of the picture screen and listen instead to music of your choice.

All photos were taken onsite in Humboldt and Del Norte Counties of northern California in 2017, 2019, and 2020. The majority of photos record ferns near Freshwater Creek, along Pacific Lumber Camp Road and upstream. The gigantic redwood trunks and bases are mostly within Prairie Creek State Park or other portions of the Redwood National Park system.

The strikingly curved bases of ancient Sitka Spruce (at the start of the loop trail for Fern Canyon) are near sea level and dominate the salt-spray landscape where Sequoia fears to tread. That begins a series featuring a kind of fern only found up on trunks and canopy — or, as seen in some photos, where a canopy branch has fallen. The penultimate 6 slides are a sequence in "Fern Canyon". The last, horizontally moving slide is along Graham Gulch, across from the old PLC camp park.

Connie's photos of diverse ferns in the eastern states were already compiled by her into the video: youtu.be/evmIGq4foVM?si=-SDSJydu8OFZ-5Zl

She has also posted a 9-episode video series on youtube that educates about and advocates for "assisted migration" poleward of California's two most famous trees: Coast Redwood and Giant Sequoia: youtube.com/playlist?list=PLJvRBS695TaV4pJEyJGOZ4FQeIByjMGbJ

And, of course, the totem ground-dwelling animal of redwood forests is the Banana Slug. Connie posted a 6-part educational video that begins here: youtu.be/16pJrak_irY?si=8aANvGMbtwfavwm3 and can also be found in her playlist titled youtube.com/playlist?list=PLJvRBS695TaUc1CAl14iD99JTilZoHLv9

Michigan welcomes endangered trees from Florida (2023)

ghostsofevolution 2023-08-22 | August 2023 Connie Barlow videoed the Florida Torreya (Torreya taxifolia) and Florida Yew (Taxus floridana) plantings in the 45-acre forest at Paul Camire's farm in Capac, Michigan. Since his earliest plantings in 2017, Paul has witnessed no evidence of winter kill on leafy branches or buds and no disease. Instead, the main problems are herbivory episodes — rarely by rodents, but massively whenever the protective cages are breached by a falling branch or a winter-starved deer. Even so, Torreya recovers again and again, putting forth new leaves and even new leaders.

TIMECODED table of topics is below, and a full chronology (with photos) is found on the Capac Michigan webpage of the Torreya Guardians website:
http://www.torreyaguardians.org/mi-capac.html

This is episode 36 in the Torreya Guardians video series. Access the full set at this playlist url: youtube.com/playlist?list=PLJvRBS695TaXwOH416C7okxBeo358sn1o

00:03 Introduction by Connie Barlow, with maps.

01:13 Close-up look at seedling planted in 2017. Two flushes of growth yearly. Compare with video from 2019, after leaves sunbleached when a canopy ash tree fell in 2018.

03:34 Visit a second seedling planted in 2017. Compare today's growth with extreme herbivory by deer filmed in 2019.

05:54 Visit a third seedling from 2017; the only one that escaped herbivory. Canopy tree species shown.

07:49 Visit fourth seedling from 2017; recovery from severe deer damage.

08:55 Newest planting: Clint Bancroft in TN donated a potted seedling to Paul Camire in 2018. Paul planted it in his forest during a warm spell January 2023. Protected by the sturdiest, tall cage. No amount of hunting reduces the deer population.

10:52 Visit the FLORIDA YEW, also planted January 2023. No winter-cold damage. At 12:20 there is an overlay of several pages of the List of Florida Yew "ex situ specimens" that Paul compiled and posted here: http://www.torreyaguardians.org/florida-yew-list.pdf

13:17 Paul shows one of the American Chestnut seedlings he planted from an organization that breeds from only native specimens. Overlay compares with Liriodendron's height.

14:37 This torreya was severely eaten by rodents; grown from the 2016 harvest of Medford, Oregon seeds.

16:18 First of 4 seedlings that Paul and Connie planted from pots in 2019.

17:44 Second of the 4 seedlings planted in 2019. Tremendous growth. At 18:17 an overlay of Paul's publication in 2018 of "Ex-situ specimens of Torreya taxifolia". The 27-page PDF is here:
http://www.torreyaguardians.org/historic-list.pdf • Typical growth spurts are leader upward in May, then laterals end of July.

19:01 Third of the 2019 set; shadier spot so slower growth. At 19:44 are photo overlays of Paul's torreyas in a winter snow. "Zero frost damage" in Michigan, but rarely some winter wind dessication of leaves, except within south side of forest. At 20:18 overlay of Fred Bess's torreyas in Cleveland OH, where experienced needle dessication during first winter.

20:27 Fourth and fullest of the 2019 plantings (in a set of beech trees). At 21:54, overlay of an aerial map of Paul's forest and nearby Mill Creek.

22:00 Surprise! A severely rodent-damaged seedling, assumed to be dead, shows new growth. This is another plant that Paul had germinated from 2016 Medford Oregon seeds.

23:18 A full-sun experiment planting: Torreya in the meadow by the South Branch of Mill Creek. 26:00 Map overlay of Black River watershed, into Lake Huron.

26:12 Location shifts to Paul Camire's home in Capac, where he nurtures potted seedlings of Torreya before ready to plant. Four new seedlings from Fred Bess seeds (overlay photos at 26:38). One new sprout from Highlands, NC seeds (overlays 26:56). As usual, 2 winters passed before seed germinated. Spring-germinated seeds do not show above ground till late June, early July.

28:56 South-facing side of house nurtures 30 potted Torreya seedlings. Provenances: Fred Bess, Jack Johnston (Highlands), and Clint Bancroft (TN).

31:18 Closing slides begin: Photo of TorreyaGuardians homepage • photos of Torreya videos 32a and 32b: Capac Michigan 2019 • photos of Paul and Connie, 2019 and 2023.

32:12 Conclusion: Connie voice-over, followed by a moving list of all the previous Torreya Guardians "assisted migration" videos.

Citizen Science discovers Pawpaw Pollinators in Michigan

ghostsofevolution 2023-04-13 | "Citizen Science discovers PAWPAW POLLINATORS in Michigan": Assembled by Connie Barlow in 2023, from video and photo documentation of fieldwork in southern Michigan: 2021–2022. Text and image resources: "Pawpaw Ecological Survey in Michigan, with Background Information, Excerpts of Scholarly Papers":
http://www.torreyaguardians.org/pawpaw-ecological-michigan.html

01:14 Summary of Results (90 seconds)

02:45 List of fieldwork sites and dates of observations (May 2021, 2022)

03:39 May 2, 2021 at Draper-Houston Meadows Preserve: Introduction to the phase development of pawpaw flowers (from female to male), historic range of Asimina triloba in eastern USA.

07:11 Continuing at Draper-Houston: full set of observations

10:46 May 7, 2021 at Pawpaw orchard of Marc Boone: Introduction

12:28 May 16, 2021 Marc Boone orchard observations (with Dallas Ford). First documentation of two tiny nitidulid beetles that will prove to be the dominant effective pollinators observed at all sites: Glischrochilus quadrisignatus and Stelidota geminata.

17:09 May 16, 2021 Draper-Houston Preserve (with Dallas Ford). Spiders, flies, and other insect visitors documented. Forest floor herb, Asaram (wild ginger), is abundant in the pawpaw patch and has flowers strikingly similar in form and color to the pawpaw flowers. Old growth pawpaw patches create their own canopy, as documented by Barlow on youtube from site visit to this preserve in September: youtu.be/S7u8opsHy5o

24:15 May 17, 2021 Ypsilanti home of Monica King (2 planted pawpaws). More flower and insect observations.

27:19 May 19, 2021 Ypsilanti home observations

32:58 May 20, 2021 Ypsilanti home observations

44:44 May 21, 2021 Ypsilanti home observations (with Dallas Ford)

48:40 comparing mite on back of pollinator beetle with previous video documentation of mites on other nitidulid beetles: carrion beetles and a burying beetle.

50:58 May 21, 2021 conclude observations at Ypsilanti home

54:41 One day of observations at Ypsilanti home in 2022 (May 14)

56:14 November 2022: Discovery of the same Glischrochilus beetle while sorting pawpaw seeds from rotting unharvested fruit from Marc Boone's orchard. Discovering larvae of the same beetle species in some of the rotting fruit.

57:22 Conclusion: "Reciprocity in nature" as exemplified by the beetle's give-and-take relationship with American pawpaw, Asimina triloba.

UPDATE SEPT 2023: I just watched the new 3-minute video of Pawpaw's local "Ambassador" on a Pittsburgh TV station, posted on youtube. Gabrielle Marsden is the guest, and she is the local person who has been planting pawpaws along the Allegheny River in places where industrial collapse now makes it possible for riverside forests to regrow. For Gabrielle, planting pawpaw is not an end in itself: She does it in order to make it possible for the Zebra Swallowtail to naturally return to Pittsburgh, as its caterpillar feeds uniquely on pawpaw leaves.

Torreya Guardians - 2022 reflections by Connie Barlow (2 decades of citizen action)

ghostsofevolution 2022-11-15 | Torreya Guardians is internationally known for conducting the first "assisted migration" action for a climate-endangered plant, Florida Torreya. Advocacy began in 2004, with actions ramping up in 2008. This network of engaged citizens, however, relied on an "exception" (just for plants) in the Endangered Species Act in order to do so legally. Finally, in 2022 the federal agency in charge of endangered species proposed updating the regulations pertaining to "experimental populations" in order to facilitate its use for climate adaptation: helping species move to cooler habitats.

Five Frisky Snakes in Michigan (April 2022)

ghostsofevolution 2022-04-22 | On the first really warm day in spring of southern Michigan (though it would snow a week later), Connie Barlow encountered these 5 garter snakes in a deciduous forest, near logs, and very near the Huron River of Ypsilanti, Michigan. The day was 10 April 2022 (the video end slide conveys the wrong date).

In Praise of Lichens - photos by Connie Barlow, music by Sydney Jill Lehman

ghostsofevolution 2022-02-22 | The earliest life form to grace Earth's land masses can be trusted to carry forward long after our own bumbling species passes into dust. "In Praise of Lichens" aggregates photos by Connie Barlow from her 18 years of living on the road in North America (Turtle Island) with husband Michael Dowd. Whenever it was Connie's time to drive, she would opt for one of the albums by musician Sydney Jill Lehman (now, Rev. Sydney Lehman Steen) — whom we first experienced at the piano in a church in Portland, Oregon, where Michael was serving as guest minister/speaker. Following is a timecoded list of landscape sites:

00:10 INTRODUCTORY COLLAGE of photos. Lichens grow naturally on open bedrock, boulders, gravestones, tree trunks and branches, and rarely on special ground conditions. Some of the most spectacularly shaped and soft (foliose) lichens only grow high up on the upper surfaces of tree branches — so we groundlings see them only when a branch breaks and falls or a creature scuffles it off its perch. In the introductory section, you will see examples of the latter, resting upon autumn fallen leaves, at timecodes 01:43 and 02:03, as well as in many of the images in the site list below.

CTL 5d - 7 Conifers of Colorado (why topoclimate matters for range projections)

ghostsofevolution 2022-02-05 | Connie Barlow filmed wild populations of 7 conifer tree species in 2017 — all within a few hundred yards of one another. The concept of "topocliimate" is introduced, as described in a 2021 paper by James Worrall and Gerald Rehfeldt, and why it is a crucial consideration in highly complex topographies, such as this site in the Colorado Rockies, 9400-feet elevation. Timecoded table of topics:

00:05 Introduction by Connie Barlow, May 2017, at 9,400 ft elevation, west of Colorado Springs.

02:15 Seven conifers all within a few minutes walk: Engelmann Spruce, Limber Pine, Bristlecone Pine, Douglas-fir, Ponderosa Pine, Rocky Mountain Juniper, Pinyon Pine.

03:21 Intro by Connie Barlow, February 2022, of a new forestry concept important for climate adaptation: "TOPOCLIMATE." Latitude, elevation, slope, and aspect all contribute to "topoclimate" distinctions in topographically complex mountains.

05:04 Image comparing branchlets and cones of all 7 conifers onsite.

06:06 Forestry paper, "Strategic Application of Topoclimatic Niche Models in Managing Forest Change," 2021, by James Worrall and Gerald Rehfeldt. Also, the 76 western tree species project of Rehfeldt and Crookston: "Plant Species and Climate Profile Predictions."

07:06 Field survey of all 7 conifer species within a few minutes walk at 9,400 foot ridgetop, owing to strong topoclimate diversity.

21:57 Tabletop comparison of branchlets and cones of all 7 conifers, plus Juniperus communis and Blue Spruce.

28:17 BRISTLECONE PINE - field observations of more specimens at two sites.

38:35 BRISTLECONE PINE - map of all locales, plus photos of the final site: the biggest trees.

39:38 MAPS of current distributions of all 7 species, with Bristlecone Pine doomed by climate change — unless "assisted migration."

42:40 Bristlecone pine shifting range suitability modelled for years 2030, 2060, 2090 shows likely extinction — so the need for "assisted migration" poleward.

44:54 History of Barlow's advocacy for "assisted migration" of an endangered "glacial relict" conifer trapped in Florida, Torreya taxifolia, began with her 2021 book, "The Ghosts of Evolution" and continues with her founding in 2005 of the citizen-led group "Torreya Guardians." (California torreya will also need help moving poleward.) Maps and images of Torreya Guardians actions: the group achieved seed production in Cleveland, Ohio, in 2018. Their website: http://www.torreyaguardians.org

• "The future of subalpine forests in the Southern Rocky Mountains: Trajectories for Pinus aristata genetic lineages," 2018, by Malone, Schoettle, and Coop. Mentions "assisted migration" as a management tool for genotypes most resistant to White Pine Blister Rust. Portrays that competition with other tree species is the biggest risk during climate change because, "To understand the potential for bristlecone pine forests to be replaced by other forest types, we merged the suitable climate space for the dominant tree species of important forest types or zones.... Douglas fir, subalpine fir, and Englemann spruce constitute the upper subalpine forests. Limber pine and lodgepole pine were used to define the lower subalpine forests. Ponderosa pine and quaking aspen (i.e., lower elevation species) are grouped to represent species encroachment from the montane zone, and pinyon-juniper was evaluated to quantify southwestern lower elevation woodland species encroachment... Under current conditions, the climate space for upper subalpine forests has the greatest overlap with the bristlecone pine climate space (81%), followed by the climate space for lower sub- alpine forests (68%), species from the montane zone (67%) and pinyon pine woodlands (6%).... By 2090 the bristlecone pine climate space is entirely shared with the climate space of other forest types. The distribution for lower elevation species’ climate space shifts up in elevation, while bristlecone pine climate space is not present and overlap declines for all forest types climate space except for pinyon pine (+21%). The 2090 climate space for lower elevation species is more frequent between 3000m and 3500m, which coincides with declines in 2090 bristlecone pine climate space." doi.org/10.1371/journal. pone.0193481

Helping Forests Walk 04 B - Is this an Old Growth Pawpaw Patch? (Michigan, 2021)

ghostsofevolution 2021-12-03 | The previous episode in this series is titled, "Helping Subcanopy Trees Migrate." There Connie Barlow suggests that a wild pawpaw patch she explored two months earlier has characteristics of "old growth." This video is therefore offered as a supplement, showing raw footage of that fruited patch along the Saline River near Milan, Michigan. It is a way for viewers to "explore" this same patch and then make their own interpretations. Do you think this patch may, indeed, be old growth? (Post your views in the comments.)

What are the signs of old growth? Connie didn't recognize these signs while she was exploring the patch — only later while editing the video. The key old growth characteristic she suggests in her subcanopy Episode 04 video is that, while pawpaw grows no taller than 30 feet, in the core of this particular patch there are no overstory trees shading them. Indeed, the amount of sun reaching the patch is strong enough to yield a total of 60 fruit visible from ground-level.

The way that subcanopy pawpaw can ultimately out-compete the overstory tree species and thereby assume the "canopy" position itself is a two-fold process. First, pawpaw spreads clonally by sending near-surface stems (rhizomes) laterally, which then pop up new vertical stems distant from the original. Pawpaw can grow vegetatively very well while shaded by a deciduous overstory; it just can't produce much fruit. But this species is very patient about reproducing. Overstory trees such as walnut and maple and hackberry eventually succumb to death by old age or windfall. But any of their own seeds that germinate and attempt to establish from their former sites will now be challenged by pawpaw putting the ground level into deep shade — too much shade for the overstory species to establish. Henceforth, the patch remains as the canopy itself. Patch stems last only half a century, max. But the cloning ability keeps popping up young ones within the patch's own shade.

Connie might not have arrived at this hypothesis had she not created a video a few months earlier that aggregated raw footage of native yew (Taxus) species in North America that she had filmed in previous years: HFW 03 - "Thinking Like a Yew" youtu.be/Tp4tfbNmGdQ

Go to timecode 40:36 of the yew video to see Connie talking about USDA information on Pacific Yew's "vegetative regeneration" whereby the yew "expresses climax sociological dominance over tall conifers." The method is similar to that of pawpaw, except yews do not produce lateral stems (rhizomes). Instead, they are masters of bending without breaking. So when a canopy tree or windfall branch smashes onto, say, a 25-foot-tall yew and pushes it over, the formerly vertical stem now stretches some 20 feet horizontally. Moreover, in the consequent sunlight, new "branches" emerge and grow upward, ultimately becoming new leaders themselves, while the original fallen trunk may itself sprout roots wherever it is in full contact with the soil.

Pawpaw's ability to send rhizomes laterally without requiring overstory treefall offers an even more assured opportunity for working toward "climax sociological dominance." And as Connie mentions in the previous (04) episode, it appears that the only place that the overstory tree species can keep re-establishing from seed is in the forest sections too often flooded with ephemeral pools for tap-rooted pawpaw to survive. But Black Willow, Cottonwood, Silver Maple, and perhaps Black Walnut can tolerate periodic flooding. So do look for that phenomenon when watching this video.

UPDATE Oct 2022: I've been editing the wikipedia page on Pawpaw (Asimina triloba) and learned that the same USDA site as for yew (above) confirms that pawpaw can dominate the "canopy": "Pawpaw creates heavy shade that reduces seedling recruitment of white oak (Quercus alba) and shagbark hickory (Carya ovata). In southwestern Illinois, an increase in pawpaw cover was attributed to defoliation of overstory trees by the linden looper. The pawpaw canopy suppressed seedling establishment of less tolerant species." The USDA webpage: web.archive.org/web/20110628001600/http://www.fs.fed.us/database/feis/plants/tree/asitri/all.html

Connie's interest in posting and linking to key documents and scholarly papers about THE ECOLOGY OF PAWPAW and its reproductive habits (and especially the mysteries of pollination and pollinators) has led to a very long and illustrated webpage, which she will continue to update: http://www.torreyaguardians.org/pawpaw-pollinator-watch.html

Helping Forests Walk 04 - Helping Subcanopy Trees Migrate

ghostsofevolution 2021-11-22 | Subcanopy trees, Pawpaw and Florida Torreya, of the eastern USA are the subjects of this November 2021 exploration by Connie Barlow of "assisted migration" — citizen style. Timecoded table of topics are below a short list of key web resources.

• Video series "Helping Forests Walk": thegreatstory.org/climate-trees-legacy.html

• "Torreya Guardians" website: http://www.torreyaguardians.org

• "Pawpaw Ecological Survey in Michigan": http://www.torreyaguardians.org/pawpaw-ecological-michigan.html

• "Finding Good Redwood Habitat in Coastal Pacific Northwest":
thegreatstory.org/redw/redwood-habitat.html

• Wikipedia: "Assisted Migration of Forests in North America": en.wikipedia.org/wiki/Assisted_migration_of_forests_in_North_America

00:05 - Introduction to Pawpaw (Asimina triloba); Michigan as northern range — fruit likely carried there by Indigenous as glaciers retreated.

02:15 - "I wonder why everyone isn't doing this." Need for helping plants walk during climate change.

04:18 - Barlow sorts seeds out of surplus pawpaw fruits gathered at Marc Boone's pawpaw and persimmon orchard.

06:12 - Traditional Indigenous value pawpaw for fiber as well as fruit. Pawpaw ideal for organic horticulture (no pesticides needed). "Even if you don't own property, why isn't everybody doing this?"

08:30 - "I'm a collapsitarian. I've already experienced governmental collapse with an endangered species that I work with, Torreya taxifolia: Florida torreya." Loophole in Endangered Species Act permits citizens to lead. Torreya is a "glacial relict." Collapsitarian means, we're not getting back to normal. Rise and fall of civilizations, as presented by William Ophuls. "This civilization needs to go down."

10:45 - History of Anishinaabe people in Great Lakes region. Robin Wall Kimmerer recovers traditional values and communicates those widely. Sustainable cultures. Also, Kyle Whyte. "These are people living in two worlds. The fear of collapse: that's settler culture. They've experienced collapse — worse than we're going to experience it."

13:45 - "I live in two worlds, and it's a shocking two worlds" — since 2013, when woke up to climate change.

14:16 - Three kinds of "ecological knowledge": traditional, scientific, local. Barlow's 4 science books; "The Ghosts of Evolution" includes pawpaw. Scientific creation story: the "epic of evolution" expands one's sense of identity, beyond our species and this time. 5 mass extinctions. "If our species makes it through, this has got to be recorded mythically, saying, 'You don't do this again!'" Instead, recover Indigenous values. "It's a worldview shift — living in two worlds." Indigenuity must be recovered.

18:00 - Western science needs to recover "natural history." Paul S. Martin, Pleistocene ecologist: "I'm a naturalist first, a scientist second." Example by Barlow of natural history observation is in her 2021 Michigan video of field work: "Is this an Old Growth Pawpaw Patch?" youtu.be/S7u8opsHy5o

24:12 - Early scientists, notably Charles Darwin, used natural history observations for discoveries. "We don't need high technology to be able to continue working at that level."

26:12 - Traditional ecological values offer "kinship" forms of Earth values: respect, responsibility, reciprocity, reverence.

26:47 - "Living in two worlds" of values and modes of observing ecological change — along with expectations of whether science and civilization will continue. "Everything that we call public lands used to be ancestral Indigenous lands."

28:30 - Story of how Torreya Guardians' focus on private lands for planting this endangered species falters when ownerships change: the plantings may not be preserved. Two examples of private owners altering landscapes.

32:08 - Barlow "outs" herself in moving into guerrilla rewilding: she plants seeds on non-private properties. Whether our species continues or not, "at least the trees will carry on."

33:41 - Barlow visited the Torreya species in California to learn best habitats for planting the Florida species. Map of the southward river route that floated seeds from Appalachians to glacial refuge in Florida. Advocates moving California torreya north, too, and for helping every native tree whose seeds are not wind-blown. "Learn as much as you can." Use Google scholar.

36:44 - "There's no reason to go into despair and feel that you can't do something. Anybody here in the United States can help native plants move north." Barlow's video series: "Climate, Trees, and Legacy," renamed to "Helping Forests Walk."

41:00 - Steps for beginning to help forests walk. Importance of "indicator plants" for finding best habitats.

44:41 - Pawpaw has "recalcitrant" seeds; cannot be stored. "Use it or lose it."

46:05 - Live video of Huron River field site where Barlow discovers an ideal "indicator plant" for guerrilla rewilding the river slope with Florida Torreya.

Helping Forests Walk - 03 Thinking Like a Yew (Connie Barlow, June 2021)

ghostsofevolution 2021-06-27 | Connie Barlow uses video documentation at 8 sites in North America, along with natural history observations, to arrive at lessons for selecting wild sites for assisted migration of native species of wild yew: genus Taxus. Time-coded topics list below:

00:00:02 - Introduction to "Helping Forests Walk" video series. Quote by Robin Wall Kimmerer. Title of episode 3: "Thinking Like a Yew." Goal: To inform others to begin helping yews migrate poleward in North America, Europe, and China — and for selecting the best habitats. UPDATE: In a June 30 email, Robin told me the naming story: "Those words actually came to us from a respected Haudenosaunee elder, Henry Lickers, as we worked together on a climate change education project; he gave us that term for the project." As well, two colleagues pointed out that the yew hedge I stand along is likely not the European yew (T. baccata) but the Japanese yew (T. cuspidata) or a hybrid of the two.

00:04:38 - Maps of native range of Pacific Yew and Canadian Yew; but actual populations are highly "disjunct". (Detailed map example of n. California.)

00:06:21 - PACIFIC YEW - Introduction to the 3 video sites and USDA information.

00:08:43 - SITE 1 - Sahalie Falls, Oregon; McKenzie River. Associated canopy trees: Western Hemlock (Tsuga heterophylla) and Western Red Cedar (Taxus plicata).

00:14:51 - SITE 2 - Olympic Peninsula, Washington state. Canopy trees are same as at Site 1 but also Douglas-fir (Pseudotsuga menziesii).

00:19:29 - SITE 3 - Icycle Creek, WA, east side of Cascade Mtns. Canopy trees are same as at Sites 1 and 2, but also Engelmann Spruce (Picea engelmannii) and Grand Fir (Abies grandis). Also along trail but not associated with the yew are Western White Pine (Pinus monicola), Lodgepole Pine (Pinus contorta), and Ponderosa Pine (Pinus ponderosa).

00:40:36 - USDA information on Pacific Yew "vegetative regeneration" whereby the yew "expresses climax sociological dominance over tall conifers."

00:42:30 - SITE 3 continues. 00:45:04 - yew pollen cones

00:47:43 - EASTERN USA yew species begins with map of North America under Pleistocene glaciation.

00:48:55 - FLORIDA YEW (Taxus floridana), a glacial relict, at 1 site in Florida, where Torreya taxifolia also is relictual.

00:55:51 - CANADIAN YEW (Taxus canadensis) introduction to 4 sites. Site 1 is in Nova Scotia, where common name is "Ground Hemlock." Maps showing similar native ranges of Canadian Yew and Eastern Hemlock. UPDATE: This 2011 article is highly recommended (and offers helpful ideas for Pacific Yew, too): "The ecology of Canada Yew (Taxus canadensis Marsh.): A review" by Steve Windels and David Flaspohler - cdnsciencepub.com/doi/abs/10.1139/b10-084

00:58:09 - SITE 2 of Canadian Yew at waterfalls, border of NY and MA. Canopy is Eastern Hemlock (Tsuga canadensis) plus smaller deciduous trees.

01:00:53 - SITE 3 is relict site s. Virginia, steep cliff.

01:01:47 - SITE 4, Keeweenaw Peninsula, n. Michigan. Canopy fully deciduous: Red Oak, Sugar Maple, Yellow Birch. Range map of Eastern White Cedar (Thuja occidentalis).

01:06:00 - 7 LESSONS for "Thinking Like a Yew"

1. Cool, dark, moist — but well drained (slopes)
2. Slope of a ravine or the north side of a mountain
3. Fires: none or rare over centuries
4. Deer rarely venture into the site because forest is dense, slope is steep, big carnivores in the ravines, falls and rapids are loud. SUGGESTION: rewild the carnivores. UPDATE: Following the reintroduction of wolves into Yellowstone in the 1990s, ecologists started calling natural deer-free areas (owing to topography and/or carnivore presence) "LANDSCAPES OF FEAR", which Barlow agrees is a superb metaphor.
5. Slope and winds encourage tree-falls.
6. Help the relict populations move north first.
7. Seek out Tsuga and Thuja canopies (rewild to Europe).

Helping Forests Walk - 01 Introduction (by Connie Barlow, June 2021)

ghostsofevolution 2021-06-07 | Introduction to Connie's new video series as an advocate of a controversial climate adaptation tool: assisted migration poleward of native plants. Connie's previous video series on this topic was titled "Climate, Trees, and Legacy." It included field experience and learnings derived from this set of trees: Torrey Pine, Joshua Tree (5 vids), Arizona Cypress, Rocky Mountain Trees (10 species), Engelmann Spruce (2 vids), "Becoming Passenger Pigeon" (eastern USA large-seeded trees), Alligator Juniper (9 vids), Redwoods and Sequoias (9 vids), and Barlow lecture on assisted migration at Michigan Tech 2015. http://thegreatstory.org/climate-trees-legacy.html

00:05 Introduction by Connie Barlow, 6 June 2021, Ypsilanti, MI). Topics include returning to s. Michigan as an elder (where she is 6th generation of colonizers) and appreciation for the original inhabitants - Potawatomi. Barlow credits botanist Robin Wall Kimmerer with the term "helping forests walk." Kimmerer, a botanist at State University of New York, is a role model for using both modern science and indigenous ways of knowing and observing for understanding plants and their ecologies. UPDATE: In a June 30 email, Robin told me the naming story: "Those words actually came to us from a respected Haudenosaunee elder, Henry Lickers, as we worked together on a climate change education project; he gave us that term for the project." Note: Kimmerer speaks of her approach in botany and ecology here: youtu.be/2WRY3GoKYPc

02:19 This series will feature traditional natural history ways of observing and interpreting as a possible bridge between indigenous and modern science. Credits Charles Darwin and her mentor, Pleistocene ecologist Paul S Martin, as her role models in natural history.
Barlow's previous 18 years of living on the road, and the past 7 with a hand-held video camera, enabled her to film native trees in wild locations, across the USA.

06:00 Closing of introduction: "So let us remember the ancestors of our own species, of trees, and let us think of the descendants, who may or may not have an opportunity to follow us."

06:34 PREVIEW, followed by an updated and remixed video of a presentation Barlow delivered in 2014 in Prescott, Arizona, titled: "Forest Trees in Climate Peril."

07:28 Walt Anderson, naturalist and teacher at Prescott College, introduces Barlow as a science writer and advocate for "assisted migration" of trees facing climate change.

08:58 Barlow begins talk by speaking of the 2014 Climate March across USA, and the pilgrimage she took (led by Walt Anderson) a few days earlier to the Alligator Juniper champion tree — and how it was saved from a wildfire by the Granite Mountain hotshots, just a week before 19 of them died in the Yarnell fire.

11:45 "Ecological anachronisms" (subject of her 2001 book) and "deep time eyes" (knowledge of paleohistory and glacial refuges). Barlow and Paul S. Martin 2004 paper, "Bring Torreya taxifolia north now." Role of (extinct) megafauna in dispersing seeds of fruited plants.

17:31 "What I'd like to do here is take you through a worldview shift... with climate changing really fast." 2014 IPCC chart shows trees are slowest of all life forms to shift ranges.

21:11 Joshua Tree as local example of a tree missing its megafaunal seed disperser; map of its paleoecological range v. future range shift. (Example of Glacier National Park losing its glaciers.) JT as "poster plant of climate change for the American west."

26:51 Florida Torreya as poster plant for the American east. Barlow founded the citizen-naturalist group that accomplished the first "assisted migration of a tree endangered by climate change." Eastern USA trees lost Passenger Pigeon acorn disperser. Anthropocene is here. Now, "nature can no longer take care of itself." Examples: beech, oaks, juniper, torreya. Climate change elevates virulence of native pests.

30:13 Barlow story of using loopholes in USA Endangered Species Act to recruit citizens to move Torreya taxifolia north — because the officials in charge refused to do so.

32:46 "You all have no idea how far north your Joshua Tree can grow.... Do you see the amount of science and natural history that needs to be done in order for us to do a responsible job [in helping forests walk]? ... Who's going to take care of the trees?"

33:30 Continues story of Torreya Guardians actions and website: http://www.torreyaguardians.org

41:07 Importance of training students in natural history and paleoecology. "There's something to be gained from breadth and experience." Paul Martin, Dan Janzen, and E.O. Wilson "they would say, 'I'm a naturalist first and a scientist second.'" Importance of field experience of California torreya and "recording associated species."

46:17 "The Man Who Planted Trees" - Jean Giono 1980s video as the mythic story for tree planters.

Burying Beetle (Nicrophorus) - Wild Action with Shrew Mole Carcass (California)

ghostsofevolution 2021-01-13 | Connie Barlow filmed this Nicrophorus burying beetle struggling to bury a dead Shrew Mole in Humboldt County, California. The beetle was frustrated by finding the carcass in the center of an old logging road. The compacted gravel would not yield. The film begins with initial discovery and awe. Barlow and her husband, Michael Dowd, struggle to figure out what was going on — noticing mites on the beetle and the arrival of flies, while confused by whether the carcass was that of a shrew or a mole. Voice over during editing, along with text addition, enables Barlow to make corrections and add what she learned about the species and its remarkable mode of co-parenting underground reproduction and larval nurturance. Filmed May 2020. Short video and stills are appended from previous instances in which Barlow encountered eastern species of carrion beetles (some, burying beetles) whilst they were feasting on mushrooms.

As of 2020 there are a total of 7 videos on my NATURE VIDEOS PLAYLIST:

Florida Torreya Experiments in New Hampshire (2019)

ghostsofevolution 2020-07-31 | Four years of Florida Torreya assisted migration experiments on forested property in southern New Hampshire at the home of Daein Ballard. Video recorded onsite by Connie Barlow, founder of Torreya Guardians, on 18 May 2019.

Ballard has a variety of woodland habitats on his property, running from Hemlock Tree Swamp to groves of White Pine, mixed hardwoods on the lower reaches of a slope, dry oak mini ridge top, and open landscapes of lawn and roadway edges. A key part of his onsite experimentation was outplanting potted seedlings near a variety of distinct canopy species. These species included hemlock, red maple, striped maple, white birch, yellow birch, white pine, red pine, red oak, white ash, black cherry, white oak, chestnut oak, American Beech, and American Elm.

As is generally known, genus Torreya needs a well-drained landscape — so hemlock swamp (with moss and ericoid shrubs dominant) offered no signs of ability to thrive. The seedlings that perished in New Hampshire's driest summer on record were in the driest habitats. And the seedlings severely pruned back or killed by icing during the winter of 2018/19 were in open areas highly exposed to what Ballard regards was the warmest winter in his experience, but a crazy mix of unusually warm and rainy episodes suddenly followed by a crashing into freezing cold. Might that mix owe to jet stream swings beyond the norm — itself caused by Arctic heating and loss of summer sea ice?

At the conclusion of this video, Ballard reflects on the suitability of Florida Torreya for assisted migration as far north as southern New Hampshire. He surmises, "Torreya is probably not going to do well here for now, unless you put it in very particular areas."

The webpage on the Torreya Guardians website that provides details and a running report on Daein Ballard's experimentations in southern New Hampshire is: http://www.torreyaguardians.org/new-hampshire.html

Future year updates will continue to be added to that webpage.

The homepage of Torreya Guardians links to information on the natural history of this rare tree, the history of conservation efforts, the controversy over assisted migration of an endangered glacial relict plant, the history of Torreya Guardians actions and experiments, a state-by-state documentation of many of these experiments, as well as a photo-rich tally of what can be learned by onsite examination of horticultural plantings nearly a century old. http://www.torreyaguardians.org

CTL 9i - Coast Redwoods Assisted Migration - Collecting,Testing, and Dispersing Seeds Northward

ghostsofevolution 2020-03-12 | This is the 9th (and possibly final) installment in Connie Barlow's video series advocating human assistance in helping the Coast Redwood, Sequoia sempervirens, advance some 300 miles northward to track ongoing climate change. Here she includes video of collecting fresh cones October 2019 at one site in California and two horticultural plantings in Oregon — north of the tree's current range in the wild. Next comes the seed germination experiments, which suggest that cones gathered from the horticultural planting in Portland Oregon contained far more viable seeds (10 to 13%) compared to cones gathered from Medford Oregon (2%) and near Orick CA (1%).

The rest of the video analyzes results, along with a summary of practical information gathered in the field and online, thus encouraging development of "best practices" for large-scale interventions in moving this ancient, relict tree species poleward — into zones of coastal Washington that mimic the fog-rich habitats of northern California where redwoods are currently native.

Surveys of existing northward horticultural plantings, along with Barlow's own experience (1) in forests of coastal Washington, (2) in Redwood old and regrowth forests of northern California, and (3) in undertaking poleward translocation of an endangered conifer in the eastern USA (Florida Torreya), have led her to hypothesize that casting redwood seeds into patches of Sword Fern may offer an easy technique and ideal micro-habitat for "free-planting" seeds directly into regrowth forest. This hypothesis draws from the paradigm of rewilding, as well as the deep-time perspective (paleoecological science) that reminds us that redwoods have been transiting north and south for tens of millions of years in accordance with the slow pace of natural climate shifts. See Barlow's 1999 essay "Rewilding for Evolution" and her 2009 chapter "Deep-Time Lags: Lessons from Pleistocene Ecology" accessible here: http://thegreatstory.org/CB-writings.html

As always, Barlow grounds quantitative results within a systems (rather than mechanistic) frame of ecological science. Observations, hypotheses, and hesitations emerge from Barlow's natural-history-style encounters with the species in its wild native habitats, poleward horticultural plantings, and (in two Seattle-area examples) "recipient" regrowth forests into which horticultural plantings have successfully launched a next generation — with no additional human help.

The last quarter of the video overlays Barlow's audio presentation of information with video and photos she collected over the years of (a) Coast Redwood in natural and horticultural settings and (b) glimpses of actual seed-casting dispersal of the newly gathered seeds into regrowth forested areas (rich in sword ferns and under deciduous canopies) at the south end of Whidbey Island, northwest of Seattle.

UPDATE: In Week 6 of the final seed germination experiment, Portland Tree #2 germinated 3 more seeds, bringing its total germination rate from 13% to 15%.

October 2021 Barlow collaborated with the Seattle-based "1000 Redwoods Project" in producing a photo-rich webpage to help Pacific NW planters of donated Coast Redwoods find the best habitats and microsites: "Finding Good Redwood Habitat in Coastal Pacific Northwest" at thegreatstory.org/redw/redwood-habitat.html

Post-Doom Death of Expectations - Connie Barlow guest sermon Dec 2019

ghostsofevolution 2020-02-20 | Connie Barlow is co-developer and video editor of the "Post-Doom Conversations" series on youtube. In this guest sermon, delivered 29 December 2019, at the Unitarian Universalist Congregation of Whidbey Island (WA), Barlow offers five patterns that she has detected among the guests telling their stories and describing their outlooks and sources of equanimity — despite a shared recognition that the future portends serious decline in many ways. The five patterns are:

(1) Diversity of outlooks
(2) Find a peer group
(3) Share stories
(4) Identity shift / myth
(5) Generational distinctions

Along the way she highlights lessons and stories from conversations hosted by Michael Dowd of these early guests to the ongoing series (all posted on youtube): Shaun Chamberlin, Joanna Macy, Dougald Hine, Rupert Read, LaUra Schmidt, Aimee Lewis-Reau, Richard Heinberg, Carolyn Baker, Ganga Devi Braun, Stephen Jenkinson, and Terry Patten.

CTL 9H - Coast Redwoods - Is climate change already stressing cone production?

ghostsofevolution 2019-11-29 | Connie Barlow visits Humboldt State University, Arcata CA, and video-documents evidence that cone production of Coast Redwoods on campus is strongly linked to the presence of artificial water sources: watered lawns, outflow of roof gutters, and sloped parking pavement.

Tree-by-tree video-documentation occurred Sept 17 and 26, 2019.

At the end of this video (timecode 56:12), Barlow adds an October 4 video documenting that red squirrels in Laurelhurst Park of Portland Oregon were busily harvesting green cones. Hence a cautionary note: Documenting presence or absence of green cones must occur prior to squirrel activity — if, indeed, red squirrels are present in the locale. As well, even though old cones remain on the tree for a year, they will be absent if squirrels harvested them the previous year.

00:08 - Barlow introduces this video as the 8th installment in the Redwood series
01:12 - Do campus redwoods produce cones only in locations with access to artificial water?
03:12 - First evidence of differential cone production on campus
07:04 - Distinction bt past year (brown) and new (green) cones

CTL 9F - Coast Redwoods Thrive and Multiply at Seabeck, WA 2019

ghostsofevolution 2019-11-07 | Crucial documentation of a mid 1980s planting of Coast Redwoods into a Douglas-fir regrowth forest west of Seattle. Site visit by Connie Barlow October 2019 shows thrival of the in-forest plantings plus multiple age groups of evident offspring: seedlings and saplings dispersing beyond the original plantings. This video is part 6 of a 9-part video series advocating "assisted migration" northward of California's Coast Redwood and Giant Sequoia trees.

CORRECTION: In the video Connie incorrectly reports that the redwoods were planted in the 1970s. The current director of Seabeck Conference Center, Charles Kraining, contributed this correction in a 7 November 2019 email to Connie:

"I think the redwoods were planted in the mid 1980s. The Director that planted them started here in 1984. He did it early in his tenure here. I would guess that like most of our trees, the deer made quick work of many. I think the video is a great asset to have for future generations and us."

October 2021 Barlow collaborated with the Seattle-based "1000 Redwoods Project" in producing a photo-rich webpage to help Pacific NW planters of donated Coast Redwoods find the best habitats and microsites: "Finding Good Redwood Habitat in Coastal Pacific Northwest" at thegreatstory.org/redw/redwood-habitat.html

Connie also created a long, photo-rich webpage of technical details on "Growth Capacities of Coast Redwood" that she posted on the Torreya Guardians website here: http://www.torreyaguardians.org/redwood-2019.html That page utilizes photos from this site in Pacific NW, along with a lot of photos from an old second-growth site along Freshwater Creek east of Eureka , California.

Also in 2021 Barlow collaborated on a new wikipedia page rich in background and linked sources: "Assisted Migration of Forests in North America" at en.wikipedia.org/wiki/Assisted_migration_of_forests_in_North_America

October 2022 the Canadian Forestry Service published a 39-page report by Richard S. Winder et al., titled, "Potential for Assisted Migration of Coast Redwood (Sequoia sempervirens) to Vancouver Island: Problems and Prospects." I have excerpted and linked the report here: http://www.torreyaguardians.org/assisted-migration.html#winder-2022

UPDATE JANUARY 2023: I just learned of a second Coast Redwood forest planting that took place in the 1990s by Hama Hama Logging Company (a subsidiary within the family owned Hama Hama Oyster Company): hamahamaoysters.com/pages/forestry
The company is located in the village of Hama Hama on the Hood Canal side of the Olympic Peninsula of Washington State. Its redwood forest is about 15 miles southwest of the within-forest redwood planting at Seabeck WA portrayed in this video.

NEW WEBPAGE REDWOOD INFORMATION IN 2023: This youtube channel owner, Connie Barlow, is corresponding with citizens in the Seattle area who are planting Coast Redwood (and Giant Sequoia) in their area. Their website is propagationnation.us

To support their effort, I created a 6-part photo-essay series on a new webpage of mine, titled, "Growth Capacities of Coast Redwoods" here: http://www.torreyaguardians.org/redwood-2019.html
The 6 sections are: (1) Redwood Lignotubers, (2) Redwoods sprout from Lignotubers, (3) Fallen Branches sprout by Layering, (4) Trunk Reiteration, (5) Propagation from Cuttings (obtaining vertical orientation) and (6) Bark Beetle Evidence (on fallen redwood branch).

VIDEO SERIES: "Climate, Trees, and Legacy" (a.k.a., "Helping Forests Walk") is
Connie Barlow's multi-part advocacy for "assisted migration" poleward of trees native to North America. As of 2023, there are 34 videos in this series, which are listed, linked, and annotated here: http://thegreatstory.org/climate-trees-legacy.html

Barlow's advocacy for "assisted migration" of native trees began in 2004 with advocacy for a glacial relict conifer, left behind in its peak glacial refuge in Florida, Torreya taxifolia. Visit the Torreya Guardians website for more information on the tree and advocacy for moving it poleward: http://www.torreyaguardians.org

CTL 9G - Coast Redwoods at Chetco River Oregon - 2019 site visit

ghostsofevolution 2019-11-07 | September 29, 2019 Connie Barlow video-documented her site visit to the northern-most wild (unlogged) grove of Coast Redwoods in America. While it lacks the immense tree sizes for which Redwood National Park (at various sites in northern California) is justifiably famous, this site in southwestern Oregon offers great hope for those of us weary of climate bad news. For it is here where one finds site evidence of this tallest tree species in the world still producing lots of offspring, which then head for the canopy themselves.

Florida Torreya Loves Tennessee - March 2019 in Ocoee Watershed

ghostsofevolution 2019-08-23 | Clint Bancroft is one of the lead volunteer "assisted migration" planters of America's most climate-endangered tree: Florida Torreya. Connie Barlow video-documents Clint's skills in siting this species into his regrowth deciduous forest of Tennessee's southern Appalachian mountains. Because Torreya is a well-known "glacial relict" that was left behind in its peak glacial refuge after the last Ice Age, it is best adapted today for the climate not of Florida but of the southern Applachian Mountains. Other videos in the Torreya Guardians series show that this species thrives even in more northern states: http://www.torreyaguardians.org/video.html

Florida Torreya in Michigan Survives -45 Degree F Windchill (Part 1 of 2)

ghostsofevolution 2019-07-15 | First Torreya Guardians video of PAUL CAMIRE's in-forest plantings of potted seedlings and also seeds from the 2016 fall harvest in Medford Oregon. His 50-acre regrowth forest/woodlot is surrounded by farm fields in the thumb of Michigan's Lower Peninsula, near the town of Capac. Florida Torreya has been documented surviving (with little or no damage) subzero temperatures before (and in other states). But this is by far the worst condition: -45 degrees F windchill during Winter 2019. And yet none of the existing evergreen leaves and overwintering vegetative buds appeared to be damaged in any way.

Connie Barlow visited 24 June 2019. This 2-part video series of that visit includes inserts of video footage Connie captured at the same site 9 months earlier: 27 September 2018.

The last half of the video features a species-by-species look at the kinds of trees growing in Paul's forest, which is entirely deciduous and full canopy. A tally of plants as indicator species where Torreya grows well will help us discern best habitats for further plantings (assisted migration) of Florida Torreya (a glacial relict) northward in this fast-warming climate.

Florida Torreya in Louisiana - Mature Grove with Seedlings (2018)

ghostsofevolution 2019-02-09 | Site visit to Caroline Dormon Nature Preserve by two Torreya Guardians 15 November 2018. Of the four long-ago horticultural plantings outside of Florida that produce seeds that have germinated into seedlings nearby (with no human help), this mature grove of Florida Torreya in Louisiana is the first one in which knowledgeable local guides could provide the complete oral history and answer questions posed by Torreya Guardians. This is thus a superb example of why "natural history" observations and inquiry can crucially help the development of best practices for "assisted migration" recovery actions to ensure that this climate-endangered tree does not slide into extinction.

Because wild Torreya ("left behind" in its tiny "peak glacial" refuge in Florida) failed to maintain mature stems beginning 70 or 80 years ago, this set of mature trees outplanted in Louisiana in 1950 offers one of very few opportunities to discern the "natural history" and adaptive forms taken on by this highly endangered species. All it needs is to be given an opportunity to grow in a climate zone outside of Florida that is conducive to good health.

Florida Torreya to Lake Junaluska NC - 10th Anniversary, 2018

ghostsofevolution 2018-12-27 | The Lake Junaluska locale in North Carolina (planted with 10 potted seedlings in 2008) offers insights for helping endangered species recovery ten years later:

1. ASSISTED MIGRATION - The plants seem to be disease-free at this latitude and elevation some 300 miles north of the historically native range in Florida.

2. ADAPTIVE GROWTH FORMS - If afforded the opportunity to grow in open sunlight, Torreya takes the form of a standard conifer. If the habitat is shaded subcanopy, its form is yew-like and growth is much slower. Because Torreya genus is not a pioneer-sere taxon, only human intervention in cutting back overgrowth shade can maximize Torreya's growth potential and induce an upright form (and early seed production). As of 2018, no reproductive structures have been observed on even the tallest individuals.

3. ROOT-EATING RODENTS - Of the original 10 plantings in 2008, only 4 remain in 2018. All 6 deaths are attributable to tunneling, root-eating rodents. Because the same-age, same genetics Torreya planting at the Waynesville site has not been afflicted in the same way, the rodent problem must be site-specific. The forest garden (Corneille Bryan) is surrounded by pavement and homes, and there are two sources of boom-and-bust foods: (a) the Red and White Oaks have multi-year cycles of acorn masting, and (b) the house in the southwest corner of the garden forest has a birdfeeder overhanging its deck that drops seed only during this seasonally occupied summer community.

4. COMPETITIVE EXCLUSION BY RHODODENDRONS - Rhododendrons and Mountain Laurels are evergreen, subcanopy shrubs. Rhodies easily outpace Torreyas. (The two horizontally growing specimens both have rhodies encroaching.)

5. REWILDING CONSTRAINTS - Unlike animals, plants cannot move to situate themselves in ideal circumstances — so we planters must attempt to find those macro sites (latitude, elevation, slope, aspect, forest type) and micro sites: rhododendron-free, deciduous canopy, extreme slopes. Until hundreds of seeds or seedlings are available for outplanting in each area, human interventions will remain necessary for ensuring speedy development of reproductive populations.
ACTIONS include: wire cages against surface rodents, removal of encroaching Rhododendrons, prompt removal of branch and treefalls. Autumn protection from antler rubbing will be important in deer habitat when a seedling reaches a height of 2 or 3 feet and until the prickly-leaf sapling loses its low branches. (Our planting site at Lake Junaluska shows no evidence of deer herbivory.) Both to deter deer and tunneling rodents, siting plants on extremely steep slopes is advised.
IDEALLY, in every "rewilding" site (distinct from full-sun, tended "orchard" sites), specimens should be numerous enough to have some managed for nearly full sunlight, some placed beneath a deciduous canopy but managed against branch-fall and rhodie intrusion, and others planted in various settings and left largely unmanaged — thus affording opportunities for learning more of Florida Torreya's natural history, preferences, and abilities to withstand and recover from setbacks.

Free-Planting Climate-Endangered Florida Torreya - 2018 Update

ghostsofevolution 2018-12-27 | Given governmental budgetary constraints, it is unlikely that full recovery and delisting of the endangered Torreya taxifolia tree can be accomplished in labor-intensive and costly ways (e.g., producing potted seedlings and later transporting them to and planting them in ultimate destinations northward of their peak glacial refuge in Florida).

Accordingly, it is vital to ascertain best practices for safely, yet inexpensively, introducing seeds directly into forest habitats — without first germinating them in protected settings (such as wire-protected soil beds or pots in botanical gardens).

Since 2013, a growing number of Torreya Guardians have been legally experimenting (beyond the constraints of the governmentally sanctioned recovery plan, which will be updated in 2019) with techniques for skipping the potted seedling step in Torreya propagation. Instead, harvested seeds are being put directly into forest habitats as their ultimate destinations. Torreya Guardians founder Connie Barlow has been the chief proponent of "free-planting" experiments and has been photo- and video-documenting ongoing results.

Seeds of Florida Torreya Produced in Ohio

ghostsofevolution 2018-10-15 | Fred Bess in Cleveland Ohio set the record in 2017 for the farthest north production of Torreya taxifolia seeds ever documented. When Connie Barlow visited him a year later, she filmed seed production that had expanded 3 or 4-fold.

In this short video, viewers will also learn that:

1. Torreya seeds are only produced when a plant gets a lot of sun — and then only on the sunniest side of the tree.

2. When a potted seedling from the south is out-planted far to the north, its leaves will at first die on the winter windiest side of the tree. But new growth will acclimatize to the cold (each evergreen leaf usually stays on the tree, photosynthesizing, for 5 or even 7 years).

3. Branchlets that are winter-killed will offer a flush of new branchlets in a ring at the base of the dead twig, thus making the tree even more leafy and compact.

4. Because a young Torreya tree is a very prickly evergreen plant, it will be the favored outlet for buck deer scraping velvet off antlers in the fall; so fencing (or stacks of surrounding brush) are crucial in the fall where deer are populous.

5. Fred's experience suggests that a few seeds will sprout after their first winter. Most will sprout after their second winter. None sprout after that. (However, other Torreya Guardians experimenting with "free-planting" seeds directly into the wild are finding that planting seeds as deep as 6 inches is an excellent way to deter rodent predation, but may delay the appearance of above-ground growth.)

Fawn twins hear moms alert but dont see me 12 feet away

ghostsofevolution 2018-09-23 | After this astonishing encounter with deer twins in Ludington Michigan, I found online that since deer evolved to see at dawn and dusk, they have trouble seeing an absolutely still object right in front of them during the day. Here you will notice that I positioned myself to capture the twins chasing each other in playful circles out in the field — only to have them decide to rest by coming into the shady mowed lawn area, right where I am standing.

I move only slightly to adjust my camera when they are looking away from me. They do hear the click when my camera finishes zooming a bit. But they really hear mom! Mom is hidden off to my right. Watch their muscles twitch whenever mom gives the alert sound. Then when her alerts get intense, they finally move toward her; grasp the correct direction to run and head on out — with mom huffing and displaying her running skills after them.

Grief and Gratitude in a Time of Climate Change (C. Barlow sermon)

ghostsofevolution 2018-08-28 | Connie Barlow's guest sermon (26 August 2018) for a Unitarian Universalist audience in Michigan conveys the anxiety and suffering of friends in Colorado, California, and Washington who are suffering yet another summer of forest fire danger, smoke, and flash flood warnings. Her message: Environmental damage (and consequent fear and anxiety) out West is clearly "21st Century." But climate change is mostly an abstract understanding in Michigan — where environmental concerns and calamities are still "20th Century".

ORIGINAL TITLE AND SUMMARY: "Michigan, My Michigan". Bedazzled by the mountain states for 48 years, this Michigander gratefully returns to the Great Lake State, bringing along the sad stories of western wildfires, water wars, and life-threatening heat waves.

BIO: Connie Barlow, born and raised in Detroit, spent every summer break during her college years at Michigan State University making beds and cleaning toilets in national parks out west. In 1970 she had her first train ride: from Detroit to Yellowstone. 1971 had her on the train again: this time to Glacier National Park. For her final 3 summers, she made the peak: She travelled by plane, for the first time, all the way up to Alaska, to Mt. McKinley National Park. There, she used her college studies to qualify as a wildlife tour guide on the buses. Since then, she's written 4 books on evolution and ecology themes and actually seen them on the shelves of university libraries. Since 2002 she has lived on the road with her husband, Rev. Michael Dowd, speaking in churches. Mostly retired now, she has ramped up her environmental activism to include climate — specifically the need for "assisted migration" of native trees poleward.

SONG: "Michigan, my Michigan" (1902, first verse)
A song to thee, fair State of mine — Michigan, my Michigan.
But greater song than this is thine — Michigan, my Michigan.
The whisper of the forest tree; the thunder of the inland sea,
Unite in one grand symphony of Michigan, my Michigan.

Note: videos of Sandhill Cranes flying and trumpeting were taken by Connie in Ludington, summer of 2018.

Rewilding Torreya Trees - Dayton, Ohio (2016-17)

ghostsofevolution 2018-08-20 | Torreya Guardians in Cleveland, Loveland (Cincinnati), and now Dayton Ohio are reporting early success with nurturing Torreya taxifolia in their forests. Florida Torreya has long been regarded as a "glacial relict" — that is, left behind at the downstream end of the Chattahoochee River system at the end of the Ice Age. It was therefore not surprising that 60 or 70 years ago, climate had already warmed well past Torreya's ability to thrive and to fend off disease agents in its small Florida refuge.

Given the rapid additional climate change ongoing now, the tree's future looks especially bleak — unless citizens volunteer to help this member of the yew family move north. That is the role of Torreya Guardians, which has been assisting this species in moving north since 2005.

Considering that the "champion" Torreya tree is in a landscape planting in a cemetery south of Dayton, Ohio seems like a sure bet for doing well in today's climate and perhaps being able to tolerate substantial warming in the decades ahead.

Connie Barlow video-interviews Diana Spiegel (with assistance from Jim Spiegel) during an onsite survey (November 2017) along the couple's forested creek-side slope. Recent deaths of ash trees (owing to the Emerald Ash Borer) is opening up more sunlight on the forest floor. A delight is discovery of a ginkgo seedling 8 feet away from a little Torreya. The ginkgo seed would have been consumed by a raccoon or fox, then pooped out in the Spiegel's forest: thus "naturalizing" on this continent that was its home in the distant past.

Michigan Monarchs Galore! (Ludington, 2018)

ghostsofevolution 2018-08-19 | Connie Barlow raised (and filmed) more than a dozen Monarch Caterpillars into butterflies during the 2018 summer, when the population seemed astonishingly strong and caterpillars were therefore very easy to find. This video is meant to be both educational and celebratory. Such beauty! Such hope for the future!

Assisted Migration of Florida Torreya to Michigan - Leelanau Peninsula

ghostsofevolution 2018-08-03 | Germination success in planting seeds directly into a rich forest habitat is show-cased during a field visit to our northern-most planter in Michigan (near Traverse City). Liana May is a professional botanist who, in April 2017, planted 100 seeds (from the fall 2016 harvest of Torreya taxifolia in Medford OR). She "free-planted" the seeds directly into the conservation easement on her 40 acres of forested property. Thankfully, by the time she received the seeds, other Torreya Guardians had confirmed an ideal way to foil rodent predation: plant the seeds 4 to 6 inches deep. Liana followed those directions, so we are expecting a satisfying proportion of the seeds to produce seedlings by fall of 2019.

October 2018 UPDATE: A total of 12 seedlings had emerged by the end of this growing season.

Florida Torreya to Cumberland Plateau (1) - Rewilding an Endangered Tree

ghostsofevolution 2018-04-11 | Episode 24a is the first of a two-part series on the assisted migration of Torreya taxifolia to a privately owned "Stewardship Forest" on the east side of the Cumberland Plateau (near Spring City, TN).

November 2015 Chris and Christina Anderson received 400 freshly harvested seeds via Torreya Guardians. As Chris explains in this video (filmed onsite exactly two years later), the seeds were immediately put into the ground in their 232 acre forest (sampling a variety of habitats for experimental purposes, but with the bulk planted in cool, moist, deep ravines. In September 2017 the first above-ground sprouts began to appear. These are featured in this video (filmed November 2017).

Of all Torreya Guardians plantings, this locale is the best example of "free-planting" and thus "rewilding." Each seed was placed 3 inches deep into the forest soil or beneath a rock (to protect from seed-eating rodents). Of the nearly 50 sprouts surveyed by Chris and the Torreya Guardians video team (Connie Barlow and Michael Dowd), only one had its apical bud nibbled off by an above-ground herbivore. More predation may ensue and thus set back early growth. Our experience, however, is that above-ground browsing of young seedlings rarely kills the plant outright. Because the lower leaves are hardened and tipped by some of the sharpest points in the plant realm, initially naive herbivores that sample the upper leaves do not damage the entire plant.

Florida Torreya to SW Ohio - preliminary report (Nov 2017)

ghostsofevolution 2018-01-23 | This is the second installment in video documentation of an assisted migration experiment of the endangered Florida Torreya into southwestern Ohio (Loveland). This video was filmed November 11-12 and documents progress in all 3 elements of this experiment led by Bob Miller:

(1) Free-planting of seeds (shallow burial, no protection) into wild regrowth forest in May 2015 (using seeds from the March 2014 seed harvest.

(2) Shallow burial outdoors in a rodent/deer impenetrable exclosure of 29 seeds planted very soon after harvest in November 2015 (from the fall 2015 seed crop).

(3) Planting into regrowth forest in autumn 2016 of two potted seedlings donated by Jim Cullowhee, grown from seeds harvested fall of 2013.

LEARNINGS: The poor success rate of the May 2015 free-planting into wild forest may owe to any combination of these factors: (1) deterioration or extended stalling of embryo development during the winter that Barlow maintained the Fall 2014 seeds above-ground prior to final distribution; (2) shallow burial accounts for heavy rodent predation of the seeds; (3) seedlings were very difficult to spot amidst the fallen leaves. In contrast, the tremendous success of the rodent-protected seeds planted six months later could be due either to (1) elimination of rodent seed predation or (2) strength of embryos owing to immediate placement in-ground following harvest.

00:05 - Discovery of just one seedling attributed to the shallow-burial free-planting of May 2015.

03:42 - Documentation of tremendous success (22 of 29 seeds) from Nov 2015 planting of seeds in outdoor rodent-protected garden. (Obviously, Bob Miller will later replant these seedlings into his forest.)

10:27 - Next day discovery of one more seedling from the May 2015 free-planting.

12:08 - Close-up look at the previous wild-planted seedling discovered, then scoping to distant view where 2 potted seedlings were planted.

12:49 - Documentation of the two wire-protected out-planted (fall 2016) seedlings that had been initially grown in pots from seeds harvested fall 2013.

CTL 9A - California Redwoods Thrive in Pacific NW (Intro & Hutt Park)

ghostsofevolution 2017-08-12 | CTL 9a is the first in a 9-part series of videos on how landscapers (beginning a century or more ago) introduced California's Coast Redwood and interior Giant Sequoia to the Pacific Northwest — ranging from Portland to Puget Sound.

Narration in Hutt Park, Seattle, is provided by Connie Barlow (founder of Torreya Guardians), Michael Foster (founder of the Seattle chapter of Plant-for-the-Planet), and Philip Stielstra (founder of "Moving the Giants to Puget Sound"). A special thanks to Jesse Curran, horticulturalist with Edmonds Parks Maintenance, who alerted Philip Stielstra to the naturalizing redwoods of Hutt Park.

00:08 - Introduction by Connie Barlow (in Jedediah Smith Redwoods State Park)
02:50 - Introduction to naturalized grove at Seabeck WA, which is shown in detail as Episode CTL 9F (2019), accessible here: http://thegreatstory.org/climate-trees-legacy.html
04:44 - Hutt Park, north of Seattle, background info
05:41 - Profiles of the 3 Hutt Park explorers on June 25, 2017 (Barlow, Stielstra, Foster)
08:43 - Philip Stielstra speaks alongside the "Mother Tree" in Hutt Park; another original mature redwood is some 50 feet away but wasn't filmed in this video.
09:34 - Philip at the oldest group of younger redwoods
12:01 - Foster speaks by a young redwood where surroundings have been pruned.
Correction: Park Staff confirm that trimmed branches and outer-bark scraping owe to removal of exotic ivy Spring 2017. Ivy removal by Earth Corps and area volunteers continues, with 3 more work sessions scheduled for 2017. Goal: total ivy removal and replacement by native Salal, Oregon grape, ferns, and mulch as ground cover.
15:37 - Michael Foster says redwoods sequester excess carbon
16:48 - Foster photo, as one of 5 climate activist 'valve turners' in 2016
16:58 - Foster & Barlow discuss severe problems caused by introduction of English Ivy
17:35 - Stielstra recounts Ivy removal; a young redwood liberated from ivy
18:47 - Smallest redwood seen before Foster and Stielstra depart; Barlow keeps exploring
19:20 - Barlow returns to the "Mother Tree" redwood; evidence of pollen cone
20:40 - Correction: both spruce trees are Norway Spruce, not Sitka Spruce
21:53 - Redwood, 12-foot-tall, has basal sprouts and nascent burls on stem
23:23 - Close look at a mature native Grand Fir conifer tree
24:15 - Discovery of a very young redwood seedling, alongside path and ivy
26:24 - A second Sitka Spruce, much younger, struggling in shade
26:54 - Discovery of a second invasive species (laurel?) from the original landscaping
27:30 - Views of invasive English Ivy creating dense coverings on mature tree trunks
28:49 - How both the invasive, ivy and laurel(?) is hard to destroy; regrows from roots
29:43 - Difference in bark bt. mature Douglas-fir and Grand Fir
30:18 - Difference in bark bt. mature Douglas-fir and Western Red Cedar
30:53 - Very large specimens of native Bigleaf Maple
31:24 - Another very young redwood seedling by path and ivy

38:06 - back to viewing a number of very small redwood seedlings
41:33 - Western Hemlock tree growing on "stilts" over a decomposing Red Cedar stump
42:14 - Resume survey of young redwoods along widest path
42:29 - Redwood seedlings struggling to rise above the shade of giant Sword Ferns
45:40 - Seedling made a 90-degree turn to find the sun
46:13 - An old Bigleaf Maple, then continue finding redwood seedlings along wide trail
48:35 - Detour on small trail to visit the biggest, oldest Douglas-fir in Hutt Park
50:24 - Discovery of the tiniest redwood seedling, underneath huge fronds of Sword Fern
51:33 - A larger redwood seedling on the opposite side of the wide path.
52:42 - Return to beginning, alongside one of the original two Redwood trees now mature
55:11 - Field videography ends, closing slides and list of affiliated groups

UPDATE ON HUTT PARK REDWOODS, DECEMBER 2019: Apparently 90% of the redwoods onsite were planted, so very few of those shown in this video are indeed evidence of full species "naturaliization." However, even though only a few are in that category, the evidence is still solid that this California native is fully capable of maintaining, reproducing, dispersing, and establishing in fog-laden regions of coastal Pac-NW. As to ongoing invasive species removal, targeted species are English Ivy, English Laurel, and Himalayan Blackberry. Replacement by natives are mostly understory species, with some Sitka Spruce, Grandfir, Shore Pine, and Pacific Madrone trees. Original non-native trees left in place are the 2 tall Redwoods, 1 Deodar Cedar, and Norway Spruce.
