Amphibians and Reptiles 



Occurrence of four species of amphibians and nine species of 

 reptiles was documented on the study area (Table 69). The snapping 

 turtle, plains hognose and mllksnake are listed by Plath (1981) 

 as species of special concern in Montana. The plains hognose and 

 milksnake are thought to be uncommon on the area as only one 

 specimen of each was observed.
