…dedicated to stewardship of San Antonio’s Natural Areas, and to promoting the understanding and appreciation of nature through educational and scientific programs.
In an urban area like San Antonio, natural areas are few and far between. FoSANA’s mission is to improve, protect, and serve these natural areas where you can enjoy the sights, sounds, and smells of nature. Working with generous benefactors, city leaders, and the people of San Antonio, we assist in maintaining the natural area parks for the enjoyment of those in San Antonio. Thousands visit San Antonio’s natural areas every week. FoSANA educates these visitors about nature and supports San Antonio’s natural areas through contributions from FoSANA membership and donations, and with volunteers who support educational and maintenance programs. If you are interested in supporting San Antonio Natural Areas, become a member, donate, or sign-up to volunteer. We hope to see you out there.
