The Balcones Canyonlands Preserve was established to set aside and manage habitat and protect populations of two endangered songbirds and six endangered karst invertebrates as well as 27 additional species found in Travis County. In addition to these listed species, the BCP is managed for the benefit of all the native wildlife of the area, and is among the nation’s largest urban preserve systems.

GCWA pinetree 2

The Golden Cheeked Warbler nests nowhere else in the world except in the oak-juniper woodlands of Central Texas. This migratory songbird builds nests of bark strips from mature Ashe juniper (locally called “cedar” or “mountain cedar”) which it binds with spider webs that it collects in its beak. These colorful native Texans spend their winters in Central America, and can be found near Austin from early March through July and August. Loss of habitat is the main threat to the survival of this species. Click here for more information about management of the golden-cheeked warbler.

BCVI CU

The Black-capped Vireo is also a migratory songbird that builds its nest in very specialized habitat just a few feet off the ground. Historical records show that this bird once nested throughout Central Texas and as far as Oklahoma and central Kansas. Today, central Texas provides habitat for the last viable populations of this species. Habitat loss, cowbird parasitism, and predation are the primary threats to this native songbird.

The Tooth Cave Pseudoscorpion is one of six endangered karst (or cave) dwelling invertebrates protected by the BCP. The Tooth Cave Pseudoscorpion resembles a tiny tailless scorpion. Reaching a size of about 4 millimeters (or about the size of a single grain of rice), this tiny eyeless predator catches small insects by seizing them with its pincers. It is threatened by loss of habitat, changes in hydrology, and by pollution.

croton texabama

Texabama Croton is a thicket-forming woody shrub usually found in canyon woodlands associated with live oak mottes. Populations of this unusual plant are monitored by Travis County BCP staff and checked for overall health, including damage due to insect and deer populations. Researchers are working to determine the relationship of the isolated Central Texas populations of this flowering shrub to the nearest populations found more than a thousand kilometers away in Alabama.

The Jollyville Salamander is a unique species that is listed as threatened under the Endangered Species Act as of September 2013. This species is not listed on the BCCP permit, but benefits from the habitat protection provided by the preserve. Ideal habitats for the Jollyville Plateau Salamander are springs, spring-fed streams, and caves with flowing water. This species is restricted to a very narrow geographic range in and around northwest Austin and several populations have been found within the boundaries of the Balcones Canyonlands Preserve.

twisted brach

The Bracted Twistflower is another Texas Hill Country species that is not listed as endangered, but which benefits from the habitat protection in the preserve. Habitat loss and grazing pressure by white-tailed deer are the primary threats to the remaining populations of this rare plant.
