P. E. Botta, Townsend S. Brandegee, Walter E. Bryant, Gustav Eisen, William M. Gabb, and others added so significantly to these collections that by 1895 John Van Denburgh was able to publish the first review of the herpetofauna of Baja California and its associated islands. We now know that Van Denburgh’s 1895 review of Baja California herpetology was very incomplete, but it served as a starting point on which others could build. During the years 1888–1892, the first major collection from central Baja California was made by Léon Diguet, a French chemical engineer employed by the Boleo Mining Company at Santa Rosalía.

Species commonly found in the oases are the California Treefrog (Hyla cadaverina), Pacific Treefrog (Hyla regilla), Baja California Slider (Trachemys nebulosa), and Two-Striped Garter Snake (Thamnophis hammondii). Conservation and Commercialization Conservation issues are a rapidly growing concern for government agencies in Mexico. Several biosphere reserves have been created in key peninsular areas, and all the islands within the Gulf of California and along Baja California’s Pacific coast are now protected.

In this work, the term endemic pertains to species restricted to the region of study as a geographical and biological unit (Grismer 1994a) rather than a political one. Therefore, some species, such as the Peninsular Leaf-Toed Gecko (Phyllodactylus xanti) and the Baja California Rat Snake (Bogertophis rosaliae), which range continuously throughout the peninsula and enter southern California, are considered endemic to Baja California. In this context, the northern limit of Baja California is the northern limit of the Peninsular Ranges at Mount San Jacinto in Riverside County, California, in the east and the Los Angeles Basin in Los Angeles County, California, in the west.
