Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA REPTILIA SQUAMATA BIPEDIDAE

Scientific Name: Bipes biporus
Species Authority: Cope, 1894

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2007
Date Assessed: 2007-03-01
Assessor(s): Hollingsworth, B. & Frost, D.R.
Reviewer(s): Cox, N., Chanson, J.S. & Stuart, S.N. (Global Reptile Assessment Coordinating Team)
Justification:
Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Geographic Range [top]

Range Description: This species is endemic to the Baja California peninsula of Mexico, where it ranges from extreme southwestern Baja California State through western Baja California Sur, to the Isthmus of La Paz and the western Cape Region.

Population [top]

Population: It is probably a relatively abundant species, but it is secretive and is not often encountered. Papenfuss (1982) collected 2,719 specimens in an extensive study of the species.
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: This fossorial species requires areas with sandy soils with abundant leaf litter; it is rarely seen on the surface. The general habitat in its area of distribution is dryland and desert, with xeric shrub vegetation. Animals are often collected close to fenceposts, and populations are believed to be able to survive in moderately disturbed landscapes. They construct an elaborate system of burrows just below the surface, usually centered on stands of vegetation.
Systems: Terrestrial

Threats [top]

Major Threat(s): There appear to be few major threats to the species, but in some places it is probably negatively by expanding intensive agriculture. Animals may be killed when encountered because of misidentification as snakes, and a fear that they attack humans. There is some collecting of animals, possibly for the pet trade, but this is believed to have a minimal impact on populations.

Conservation Actions [top]

Conservation Actions: It is present in the large Vizcaíno Biosphere Reserve, and in some other protected areas. It is protected by national legislation, with the NOM (2003) listing this species under the Pr category (special protection).
