02:24 - why natural history observations in Calif help Florida Torreya
02:53 - brief background on Florida Torreya as "left behind"
03:21 - photos of diseased torreyas in native Florida habitat
03:32 - anthropogenic climate change as an additional stress
03:41 - north Georgia is where ESA officials have seed orchards
04:15 - 2004 Barlow & Martin advocacy paper re moving Torreya
04:49 - importance of finding northward limits of species viability
05:03 - goal: "to get this species out of the hospice wing" ("rewilding")
05:56 - "free-planting" seeds directly forest, while avoiding seed predation
06:21 - natural history observations indicate Torreya is a sub-canopy species
07:11 - CALIF SITE 1A - Robert Louis Stevenson State Park
11:43 - CALIF SITE 1B - a mountain ravine near Calistoga
15:15 - CALIF SITES 2 and 3 - Sequoia and Yosemite Natl Parks
21:24 - key conclusions re sun, moisture, and interspecies competition
21:42 - Torreya's big advantage for shade: a very big seed
22:12 - Torreya's ability to shift leaf arrangement based on sun or shade
22:27 - images of seedlings, often sprouting in deep shade
23:10 - genus Torreya often grows as double or triple stems
24:10 - similarity of Torreya and Hemlock (Tsuga) as subcanopy capable
24:36 - need to "reduce expectations" re growth speed in wild forest
25:22 - continue to part 2 for final Calif site: champion size trees
