Boynton’s Sand Post Oak is another endangered native tree in USA, Help!

This shrubby tree (1-6 meters) was originally identified in Angelina County, Texas but was last seen there in 1953. Much of that original Texan habitat has been altered for pine plantations or pasture. The species was suspected to be extinct until a population was discovered in St. Clair County, Alabama in 1994. Very little information is known about this tree, where it is, and how many are left. Five to twelve populations are known to be left in Alabama sandstone glades in mixed oak-pine-hickory forest, according to Al Schotz of the Alabama Natural Heritage Program in 2010. Other sources (e.g., the IUCN) note that the original populations are extinct, but other populations may exist in Louisiana and Mississippi. The IUCN cites the need for updated information and lists the tree as endangered.
