Florida Torreya (Torreya Taxidolia) Recovery Plan

摘要

Florida torreya (Torreya taxifolia) is a small gymnosperm tree native to four counties along the Apalachicola River and Lake Seminole in northwest Florida and adjoining Georgia. Some of the torreya's habitat is protected on lands managed by The Nature Conservancy, the Florida Park Service, and the U.S. Army Corps of Engineers. The species is endangered because the wild populations have succumbed to stem cankers and stem and needle blight that has killed the main trunks of all the mature trees leaving only stump sprouts that rarely live long enough to bear seed. The trees may be vulnerable to decline because of stress caused by habitat alteration and/or drought. Cultivated trees are also affected by fungal infections including stem and leaf blight of varying severity.
