- We inventoried the herpetofauna of FRMR in 1993 (Busby et al., 1994).
Drift fences with funnel traps were used in the Republican and Kansas river valleys, areas that contain distinctive bottomland habitats not found elsewhere on FRMR and that generally lack the surface rock or other cover objects that can be searched with opportunistic methods.
Opportunistic surveys were performed in a variety of habitats throughout FRMR at all times of the day.
The record rainfall levels of 1993 (total precipitation on FRMR was 135.4 cm in 1993 vs.
- Most species of reptiles and amphibians reported from Riley and Geary counties through 1929 were confirmed on FRMR in 1993 (Table 1).
In our study, a disproportionate amount of time was spent in sandy bottomlands, a rare habitat of FRMR. This was the one habitat where Cnemidophoris sexlineatus was encountered commonly; elsewhere this lizard is found occasionally in sparsely vegetated uplands.
Burt (1927) reported that this lizard was "sometimes taken in small numbers under flat rocks, or near them, and several have been seen in the sand dunes along the Kansas River." These observations and the large number of specimens taken from this area before 1930 suggest that Phrynosoma cornutum has declined on FRMR, as it has through much of its range (Price, 1990).
In any event, we found no evidence for amphibian declines on FRMR.
- The herpetofaunal assemblage in the FRMR area has experienced modest changes in species composition and relative abundance since the 1920s.
