U.S. Army officials near San Antonio have successfully lobbied local officials to pass a new ordinance making it more difficult for developers to build new properties near Camp Bullis, a key subsection of Fort Sam Houston. The primary weapon used by the military in this development battle has been five endangered species, including the golden-cheeked warbler. It’s not that Army brass are big bird lovers—rather, they just want to keep the federally-protected bird off their own territory, which is becoming difficult to do as civilian developments drive the animals toward Camp Bullis. Having migrating endangered species on the military base forces the Army to limit its training exercises and new developments of its own.
