ghostsofevolution | Ancient Florida Torreya in Columbus Georgia @ghostsofevolution | Uploaded February 2015 | Updated October 2024, 3 minutes ago.
While visiting the famous sole remaining Torreya taxifolia in Columbus, Georgia, Connie Barlow was struck by its location right along a free-flowing section of the Chattahoochee River. The Chattahoochee is the main conduit between the peak-glacial plant refuge in n. Florida (along the Apalachicola River) and the southwestern Appalachian Mountains, where it would have lived in warmer times.
"Might this ancient Torreya actually have been growing as a wild, native tree when the early white settlers built their first homes there?" asks Connie.
In this video she records the origin of that new hypothesis, as she rounds the bend and sees the close proximity of the ancient tree to the river. Also, the home whose front yard is graced by the Torreya has a historic registration plaque by its door: built in 1892, it reads.
In this 24 minute video, Connie takes viewers on a visual tour of that portion of the Chattahoochee, of the tree itself, its surrounds, and a variety of evidence that supports a "this tree is native here!" conjecture.

22:57 - New conjecture post-video recording: Might Torreya taxifolia have become "left-behind" in its N. Florida peak glacial refuge because the Chattahoochee River flows southward? The tree could have used the river current to make a quick migration southward (its seeds floating downstream), but it would have been utterly dependent on the much slower actions of squirrels burying its seeds for the the return trip north.
