Checklist of Amphibians and Reptiles
of the El Paso-Juarez Border Region


Carl S. Lieb, R. G. Webb, and J. D. Johnson, Laboratory for Environmental Biology, Centennial Museum, University of Texas at El Paso

The arbitrary geographic limits of the El Paso-Juarez border region, with El Paso-Juarez at its center, form a rectangular area bounded by Deming and Columbus, New Mexico, to the west; Radium Springs, New Mexico, to the north; and Van Horn, Texas, to the east. This list is conservative. It excludes some species of questionable occurrence and includes those species whose occurrences are well documented.

Pictures are available for some of the amphibians and reptiles; these are marked by §. Links without this symbol have some information, usually the taxonomic context and a distribution map within the Chihuahuan Desert Region.

Since the checklist was completed by Lieb et al., a number of names have changed. These have been updated by A. H. Harris in January of 2011 who also added a number of links to photographs on the Centennial Museum site (use your return button to return to the checklist).
