01:38 Torreya taxifolia as a "glacial relict" left behind in Florida
01:51 2 specimens of Florida Torreya
01:55 Month difference in timing of budburst of Chinese v. Florida species
02:58 Nearby maple (and other trees) have same beneficial root fungi
04:27 View of closed deciduous canopy above healthy torreyas
05:16 Detailed look at Florida Torreya specimen A and yearly growth
08:27 Two basal sprouts of specimen A (basals are natural)
10:21 Detailed look at Florida Torreya specimen B
13:53 Final assessment: Florida Torreya specimens very healthy
14:05 Thrival of both specimens despite deep cold snaps in winter
14:21 Detailed look at Chinese Torreya grandis

This video of 18 June 2016 is part of an ongoing monitoring program to learn just how far north, and in what habitats, the Florida species of genus Torreya is capable of growing in this rapidly changing climate.

Two WIKIPEDIA pages put the citizen efforts of Torreya Guardians in context of the overall need for "assisted migration" poleward of native trees:
"Assisted Migration of Forests in North America" - en.wikipedia.org/wiki/Assisted_migration_of_forests_in_North_America
"Torreya Guardians" - en.wikipedia.org/wiki/Torreya_Guardians
