should be recorded. The historic sites for all amphibians, particularly Northern Leopard Frogs 

 and Bullfrogs, should be re-surveyed. Such baseline distribution information is necessary before 

 monitoring sites are chosen. 



South Dakota Unit Information 



Information from these Units is not as complete due to lack of access to museum records from 

 South Dakota; collection of this data alone would be a major project and was not part of the 

 study plan. The following information is based on our survey and Visher (1914) for historical 

 perspective. It is likely that most of the species known from the Montana Units will eventually 

 be found in the South Dakota Units. 



North Cave Hills: Three species of amphibians were found on this Unit: Tiger Salamander, 

 Western Chorus Frog, and Northern Leopard Frog. Tiger Salamanders were found in most large 

 ponds or reservoirs surveyed in June; they had apparently transformed and left the ponds by 

 September. Both frogs appear widespread, although only one Northern Leopard Frog breeding 

 site was located. Given the meager information available from this range, all sightings of 

 amphibians (except perhaps Western Chorus Frogs) and reptiles are of interest and should be 

 recorded. 



Baseline distribution information, particularly for species not yet recorded and for breeding 

 sites of known species, is necessary before monitoring sites are chosen. However, Ash Tree 

 Reservoir, Schleichart Reservoir, and the ephemeral pond at Fuller Pass should be examined 

 more closely as possible sites; if they are found to have two or more species breeding in them in 

 some years, they would make good candidates. 



South Cave Hills: Three species of amphibians were also found on this Unit: Tiger Salamander, 

 Western Chorus Frog, and Northern Leopard Frog. Tiger Salamanders were found at a single site 

 in June and had transformed and left the reservoir by September. Both frogs may be widespread 

 although no Northern Leopard Frog breeding sites were located. The Plains Garter Snake was 

 found just to the south of the Unit. Given the meager information available from this range all 

 sightings of amphibians (particularly breeding ponds) and reptiles are of interest and should be 

 recorded. 



Baseline distribution information, particularly for species not yet recorded and for breeding 

 sites of known species, is necessary before monitoring sites are chosen. Notably, Dry Creek 

 Reservoir had all three species recorded, is easy to access, and may make a good candidate. 



Slim Buttes: Three species of amphibians and two species of reptiles were found on this Unit: 

 Tiger Salamander. Western Chorus Frog, Northern Leopard Frog, Painted Turtle, and Racer. 

 Tiger Salamanders were found at two sites in June. Both frogs may be widespread, although 

 only two breeding sites were located for each species. The Painted Turtle was found at two 

 locations, although the northern site at Reva Pass was a single individual in a very small pond 

 that probably dries up in the summer. Given the meager information available from this range all 

 sightings of amphibians (particularly breeding ponds) and reptiles are of interest and should be
