Reptiles & Amphibians

NOTES:

Species listed. Unless otherwise noted, species names are according to Crother (2008). Following the main list is a list of species reported in the ‘Observed and Expected Fauna’ in the 1999 EIR but not confirmed by observation.

Photos and descriptions. Links labeled ‘BFS’ are pages created for the Bernard Field Station. Photos on the BFS pages may be used for any personal or academic purposes as long as notification of use is sent to the BFS Webmaster and the image is clearly credited with ©[Name of photographer]. For higher-resolution images, please contact the photographer. Note that no photos taken at the BFS may be used for commercial purposes without the express permission of the Claremont University Consortium. You must have pop-ups enabled to view the BFS pages.

Links labeled ‘WERC’ are to species accounts in A Field Guide to the Reptiles and Amphibians of Coastal Southern California by Robert N. Fisher and Ted J. Case, available online from the the USGS Western Ecological Research Center.

‘CP’ links will return all photographs of the listed taxon in the CalPhotos, Digital Library Project database. As indicated above, some of these taxa may not, in fact, occur on the BFS. Note that you must check the stipulations with each photograph for permissible uses of the CalPhotos images.

Lizards:

California Legless Lizard Anniella pulchra

Reported in the 1999 EIR as Anniella pulchra pulchra, but A. p. pulchra and A. p. nigra are no longer recognized as separate subspecies (2003 Crother update).

FSC, CSC, USFS S BFS, CP, WERC
Coastal Whiptail Aspidoscelis tigris stejnegeri

Originally reported as Cnemidophorus tigris multiscutatus; however, Crother (2001) assigned the coastal Southern California species to C. t. stejnegeri, and the 2003 Crother update reassigned the genus to Aspidoscelis. The Field Station Manual reported the whiptail on the BFS as C. t. mundus (now A. t. munda), but this identification is almost certainly in error — see range map.

Southern Alligator Lizard Elgaria multicarinata

Formerly known as Gerrhonotus multicarinatus

S, M BFS, CP, WERC
Blainville’s Horned Lizard Phrynosoma blainvillii

Phrynosoma blainvillii was until fairly recently considered a subspecies of Phrynosoma coronatum; however, in 2004 it was elevated to a separate species (Crother 2008).

FSC, CSC, USFS S, M BFS, CP, WERC
Western (Skilton’s) Skink Plestiodon skiltonianus skiltonianus

Formerly Eumeces skiltonianus skiltonianus; changed to Plestiodon in Crother (2008).

S CP, WERC
Western Fence Lizard Sceloporus occidentalis

Reported in the 1999 EIR as Sceloporus occidentalis biseriatus, but the subspecies designation seems unlikely given its range.

S, R, M BFS, CP, WERC
Side-blotched Lizard Uta stansburiana

Reported in the 1999 EIR as Uta stansburiana hesperis, but this subspecies is not recognized in Crother (2001).

S, R, E, M BFS, CP, WERC

Snakes:

California Striped Racer Coluber lateralis lateralis

Originally reported as Masticophis lateralis lateralis, but now considered to be in genus Coluber (Crother 2008).

S, E BFS, CP, WERC
San Bernardino Ring-necked Snake Diadophis punctatus modestus FSC, USFS S CP, WERC
San Diego Night Snake Hypsiglena ochrorhyncha klauberi

Originally reported as Hypsiglena torquata klauberi; assigned to H. ochrorhyncha supspecies klauberi in 2006 (Crother 2008).

S, M CP, WERC
California Kingsnake Lampropeltis getula californiae FSC S CP, WERC
Gophersnake Pituophis catenifer

Originally reported as Pituophis melanoleucus, but this species is now restricted to the related Pinesnakes found in the Eastern U.S. (Crother 2001).

S BFS, CP, WERC
Western Black-headed Snake Tantilla planiceps S CP, WERC

Turtles:

Western Pond Turtle Actinemys marmorata

Previously reported as Clemmys marmorata pallida; assigned to Actinemys in the 2003 Crother update. The subspecies pallida is no longer recognized (Crother 2008).

Frogs & Toads:

Southern California Toad Anaxyrus boreas halophilus

Previously reported as Bufo boreas halophilus. The genus Bufo was recently determined to be paraphyletic; North American toads are now placed in Anaxyrus (Crother 2008).

FSC S BFS, CP, WERC
American Bullfrog Lithobates catesbeianus

Exotic. Native to the Eastern U.S., L. catesbeianus has now been introduced into many places in the Western U.S., including California. Formerly Rana catesbeiana.

J, S CP, WERC

Salamanders:

Garden Slender Salamander Batrachoseps major major

Listed in the 1999 EIR as Batrachoseps pacificus major; however, recent revision elevates this taxon to a species, B. major, with two subspecies (Crother 2001). See also a discussion of the species formerly classified as B. pacificus by the USGS Northern Prairie Wildlife Research Center.

S BFS, CP, WERC

Species listed in ‘Observed and Expected Fauna’ in the 1999 EIR, but not confirmed at the BFS:
Western Yellow-bellied Racer Coluber constrictor mormon
Red Racer Coluber flagellum piceus

Originally reported as Masticophis flagellum piceus, but now assigned to genus Coluber (Crother 2008).

Southern Pacific Rattlesnake Crotalus oreganus helleri

Rattlesnakes have been extirpated from the BFS. Listed in the EIR as Crotalus viridis helleri; assigned to C. oreganus in the 2003 Crother update.

California Mountain Kingsnake Lampropeltis zonata

Originally reported as Lampropeltis zonata pulchra, but subspecies of L. zonata are no longer recognized (Crother 2008).

Southwestern Threadsnake Leptotyphlops humilis humilis
Coast Patch-nosed Snake Salvadora hexalepis virgultea
California Lyresnake Trimorphodon biscutatus lyrophanes

Listed in the 1999 EIR as T. b. vandenburghi; however, this sub species was synonymized with T. b. lyrophanes (Crother 2001).

Baja California Treefrog Pseudacris hypochondriaca

Listed in the 1999 EIR as Hyla regilla; however, Crother 2001 placed the species in Pseudacris, and Crother 2008 recognized the Pseudacris in our area as a distinct species from P. regilla.

Arboreal Salamander Aneides lugubris
Black-bellied Slender Salamander Batrachoseps nigriventris
Monterey Ensatina Ensatina eschscholtzii eschscholtzii
