In 2010, Gorgas Science Foundation (GSF) reached an agreement with Audubon Texas to lease and operate the Sanctuary, allowing us to reopen this incredible place to the public.

GSF was established in Brownsville in 1947 by Texas Southmost College Biology Professor Barbara T. Warburton. In 1983, Mrs. Warburton along with former students and local volunteers formally incorporated GSF as a registered 501(c)3 foundation.
