ABSTRACT 



A brief inventoty of the Thompson Chain of Lakes was conducted in May-June 2000 for 

 amphibians and reptiles in the complex of wetlands present there. Twenty-six site surveys at 16 

 sites revealed the presence of four amphibian species and three reptile species at 13 sites; one 

 species was detected at 5 sites, two species at 4 sites, three species at 3 sites, and four species at 

 I site Amphibians detected included long-toed salamander (Ambystoma macrodactylum) at 8 

 sites, western toad (Bufo boreas) at 2 sites. Pacific tree frog {Hyla regilla) at 2 sites (also heard 

 calling from a cattail area in one of the main lakes), and Columbia spotted frog {Raiia 

 luteiventris) at 5 sites. Reptiles detected included painted turtle {Chrysemys picta) at 6 sites, 

 common garter snake {Thanmuphis sirtalis) at 2 sites, and western terrestrial garter snake 

 (Thanmuphis elegans) at 1 site. Total individuals and egg masses seemed low for the amount of 

 available, apparently suitable, habitat However, amphibian/reptile species richness at the 

 Thompson Chain of Lakes is at or near expectation, and the inventory revealed all of the 

 anticipated amphibian and wetland-associated reptile species, with the possible exception of the 

 northern leopard frog {Rana pipiens).
