RESULTS AND DISCUSSION 

 General Summary 



A total of 102 sites was surveyed during the months of April (22 surveys). May (32 surveys), June 

 (34 surveys), and July (14 surveys) in 1998 (see Appendix 1). Eight of the 1998 surveys were 

 roadside nocturnal call surveys, rather than the standard site surveys. Eight additional sites (3 in 

 June, 5 in July) were surveyed on BLM lands in Carbon County in 1995 (see Appendix 3a). Of 

 the total 110 sites, 100 (90.9%) had one or more amphibian or reptile species present (Appendix 2 

 and 3b). During the 1995 surveys, 3 of the 8 sites (37.5%) had one or more amphibian species 

 present; in 1998, 97 (95. 1%) of 102 surveys had one or more amphibian and/or reptile species 

 present. Localized areas across the entire region were covered in the inventory. Although no 

 species were found at 10 sites, their absence may have been due to the time of day, weather 

 conditions, or other factors at the time of sampling. 



Ten species (6 amphibian, 4 reptile) were detected during site surveys within the Miles City 

 District, BLM (Table 1). Two amphibian species (Boreal Chorus Frog, Pseudacris triseriala, and 

 Northern Leopard Frog, Rana pipiens) were the most abundant (detected at > 50% of all site 

 surveys) and widespread, while the Plains Garter Snake (Thamnophis radix) was the most 

 abundant and widespread reptile species (detected at > 20% of all site surveys).

 call surveys unique for this species.
