ghostsofevolution | Florida Torreya to SW Ohio - preliminary report (Nov 2017) @ghostsofevolution | Uploaded January 2018 | Updated October 2024, 6 minutes ago.
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.
