Results/Conclusions I found that amphibians are particularly sensitive to urban development. Only four amphibian species were estimated as present in the three urban streams surveyed, whereas I estimate between 12 and 14 species in non-urbanized streams. Contrastingly, reptiles were more species rich in urban riparian areas relative to other land use types. Within the amphibians, data from previous work indicates that salamander density is best predicted by development at the watershed-scale. Data collected as part of this study suggest the same pattern does not hold for anurans. Anuran counts (as indexed from automated recording devices) were best predicted by the amount of deciduous forest within a 1 km buffer of the monitoring point. The data suggest that monitoring protocols designed to evaluate effects of a stressor on herpetofauna are likely to be flawed if they do not separately evaluate amphibians and reptiles. Furthermore, within the amphibians it is important to appreciate that salamanders are subjected to land use patters far beyond the stream edge, as stream beds act as an attractor of non-point source pollutants and increased runoff in urban areas. Anurans are not subjected to this same dynamic and therefore respond to land use patterns at a much smaller scale.
