ghostsofevolution's video: Florida Torreya in Louisiana - Mature Grove with Seedlings 2018

Site visit to Caroline Dormon Nature Preserve by two Torreya Guardians 15 November 2018. Of the four long-ago horticultural plantings outside of Florida that produce seeds that have germinated into seedlings nearby (with no human help), this mature grove of Florida Torreya in Louisiana is the first one in which knowledgeable local guides could provide the complete oral history and answer questions posed by Torreya Guardians. This is thus a superb example of why "natural history" observations and inquiry can crucially help the development of best practices for "assisted migration" recovery actions to ensure that this climate-endangered tree does not slide into extinction. Because wild Torreya ("left behind" in its tiny "peak glacial" refuge in Florida) failed to maintain mature stems beginning 70 or 80 years ago, this set of mature trees outplanted in Louisiana in 1950 offers one of very few opportunities to discern the "natural history" and adaptive forms taken on by this highly endangered species. All it needs is to be given an opportunity to grow in a climate zone outside of Florida that is conducive to good health. All citizens and scientists who are working toward species recovery and de-listing are encouraged to carefully watch and learn from this 2-part video set.
