ghostsofevolution | FL Torreya to North Carolina (pt 2): 2015 progress report (Junaluska, NC) @ghostsofevolution | Uploaded June 2015 | Updated October 2024, 15 minutes ago.
Part 2 of Torreya Guardians video report of ongoing results of a rewilding project begun in 2008: assisted migration of the endangered Florida conifer tree, Torreya taxifolia, northward to its ancestral "home" in the southern Appalachian mountains.
Evaluating and measuring the young trees 7 years after planting, the founder of Torreya Guardians (Connie Barlow) draws some conclusions — and more questions — that will be crucial for helping this ancient tree cope with continuing climate change this century.

00:13 Intro to 2-part series: Waynesville NC and Junaluska NC planted 2008
03:43 Torreya taxifolia as a "deep-time native" of western North Carolina
04:50 Scientific investigations: what is northern range limit? habitat preferences?
05:48 3 trees were killed first winter by voles stripping bark, so wire cages added
07:00 All 31 trees planted in 2008 were named for botanists and conservationists
09:07 William Bartram Tree: video report
10:49 Rachel Carson Tree (discovery: some buds sprout on older branch sections)
15:24 Aldo Leopold Tree (rhododendrons encroach; original stem died)
18:36 Lucy Braun Tree (on steep slope; mature white oaks create shade)
21:02 Wangari Maathai Tree (2 stems, compare vertical growth patterns)
24:00 Hazel Delcourt Tree (tallest; branches favor sun-side; buds also on old stems)
28:09 Henry Thoreau Tree (2nd tallest; white pine neighbor dapples sunlight)
32:04 chart compares measurements of Hazel and Henry trees
32:26 Final section: Connie Barlow narrates analyses and conclusions
34:00 Q: Why are Hazel and Henry so much taller than the other 5 trees?
35:00 Chart of data for all 7 torreya trees at Junaluska NC
35:29 Data problem: counted only buds at tips — not on old branch sections
36:08 Missing data on Bartram and Braun trees means cannot see 2013–15 trends
36:58 Waynesvile NC site data and analysis begins here
37:30 Maxilla Evans Tree is healthiest of the Waynesville trees
38:09 Sara Evans describes her mother's role in origin of Junaluska garden site
39:10 Comparing 2,600-ft Junaluska v. 3,400-ft Waynesville elevation sites
39:45 Negative results (tree deaths at Waynesville) helpful for learning
40:13 Conclusion: east-facing slope may be best (least afternoon heat)
41:22 Problem: all trees harmed by too long in pots before planting (rootbound)
42:18 Annie Dillard Tree had original stem die; 2 basal stems are now primary
43:01 Caution: Tree stressed if sun/shade shifts bt the potted v. planted habitats
44:11 In 2013 some seeds planted directly into soil at Waynesville site (video)
