Example text

Schmidt 1922 and Van Denburgh 1922 have remained the best descriptive accounts of the Baja California and Gulf of California herpetofauna to date. Other works concerning large segments of Baja California’s herpetofauna were mostly island checklists (Van Denburgh 1905; Van Denburgh and Slevin 1914, 1921a; Cliff 1954a,b; Soulé and Sloan 1966; Savage 1967; Bostic 1975; Wilcox 1980; Murphy and Ottley 1984, Grismer 1993, 1999b, 2001a), none of which treated simultaneously the Pacific and Gulf islands.

The sheer numbers of specimens that have been removed from some areas are also alarming. I was told by two Mexican nationals from La Paz that they helped one American reptile dealer collect over one thousand San Lucan Banded Rock Lizards (Petrosaurus thalassinus) in the Cape Region for over two years. Many of these were sold, and others provided the parental stock for illegal captive propagation. Commercialization of this herpetofauna threatens insular endemics most of all. For example, the Isla Todos Santos Mountain Kingsnake (Lampropeltis herrerae) is confined to a single, tiny island off the coast of Ensenada.

35 The Herpetofauna are conspicuously absent from the mesic California and Baja California Coniferous Forest regions of the northwest and, to a large extent, the Sierra la Laguna Region of the Cape. There is also a Saxicolous Group that is generally restricted to the more arid, rocky areas of the Peninsular Ranges. Members of this group usually range throughout many phytogeographic regions and show little geographic variation. The limiting factor of their distribution seems to be the presence of rock, and the species of this group are usually endemic to Baja California.
