Wildlife Watching Amphibians and Reptiles  This checklist includes 24 species which currently occur within the Carrizo Plain National Monument. Also included are two species (indicated with a "?") which may occur in the Carrizo Plain National Monument, but have not yet been verified. This checklist can best be used with a field guide to amphibians and reptiles that provides identification and natural history information. Species common and scientific names generally follow Laudenslayer and Grenfell (1983). The Carrizo Plain National Monument encompasses a variety of habitat types. The major habitat types include Juniper,Mixed Scrubland, Alkali Desert Scrub and Annual Grassland. The habitat classification used in this checklist is generally based on A Guide to Wildlife Habitats of California (Mayer and Laudenslayer 1988) and Preliminary Descriptions of the Terrestrial Natural Communities of California (Holland 1986).  State or Federally listed species.    Amphibians Habitat Occurrence Salamanders - ORDER Caudata     Lungless Salamanders - Family Plethodontidae     Black-bellied Slender Salamander  Batrachoseps nigraventris JUN/MSC Common Frogs and Toads - ORDER Salientia     Spadefoot Toads - Family Pelobatidae     Western Spadefoot Toad Scaphiopus hammondi MSC/ASC/AGS Common True Toads - Family Bufonidae     Western Toad Bufo boreas MSC/ASC/AGS Common Treefrogs and Relatives - Family Hylidae     Pacific Treefrog Pseudacris (Hyla) regilla  JUN/MSC/ASC/AGS Common    Reptiles Habitat Occurrence Lizards and Snakes - ORDER Squamata     Iguanids - Family Iguanidae     Blunt-nosed Leopard Lizard  Gambelia sila MSC/ASC/AGS Common Western Fence Lizard Sceloporus occidentalis JUN/MSC Common Side-blotched Lizard Uta stansburiana JUN/MSC/ASC/AGS Common Coast Horned Lizard Phrynosoma coronatum JUN/MSC/ASC/AGS Uncommon Night Lizards - Family Xantusiidae     Desert Night Lizard Xantusia vigilis JUN/MSC/ASC Common Skinks - Family Scincidae     Gilbert's Skink Eumeces gilberti JUN/MSC/AGS Uncommon Whiptails and Relatives - Family Teiidae     Western Whiptail Cnemidophorus tigris JUN/MSC/ASC/AGS Common Alligator Lizards and Relatives - Family Anguidae     Southern Alligator Lizard Elgaria multicarinata MSC/AGS Uncommon California Legless Lizards - Family Anniellidae     California Legless Lizard Anniella pulchra JUN/MSC Uncommon Colubrids - Family Colubridae     Racer Coluber constrictor MSC/ASC/AGS Rare Coachwhip Masticophis flagellum MSC/ASC/AGS Common California Whipsnake Masticophis lateralis JUN/MSC Common Western Patch-nosed Snake Salvadora hexalepis JUN/MSC/ASC/AGS Rare Glossy Snake Arizona elegans MSC/ASC/AGS Uncommon Gopher Snake Pituophis melanoleucus JUN/MSC/ASC/AGS Common Common Kingsnake Lampropelts getula JUN/MSC/ASC/AGS Uncommon Long-nosed Snake Rhinocheilus lecontei JUN/MSC/ASC/AGS Rare Common Garter Snake Thamnophis sirtalis JUN/MSC/AGS Rare California Black-headed Snake Tantilla planiceps JUN/MSC/AGS ?
