Anthropogenic forces are a major contributing factor to the general decline of biodiversity worldwide. Amphibians are declining throughout their habitats in North America, for example. Specifically, amphibians and their habitat are threatened with the loss of small wetland breeding pools, clearing/conversion of adjacent non-breeding habitat, and loss of landscape connectivity or fragmentation of habitat (Baldwin and deMaynadier 2009). Loss of wetland buffer zones may be due to human activities like the intensification of agricultural farming and encroaching of urban sprawl, which are threats that are observed in the loss of seasonal wetlands. Through Geographic Information Systems (GIS), these at-risk habitats threatened by one or more than one of these threats will be identified in 1992 and 2006 in Missouri and Wisconsin and statistically measured to examine the conservation effects from the U.S. Supreme Court decision Solid Waste Agency of Northern Cook County vs. U.S. Army Corps of Engineers (SWANCC). This fifteen year old legal decision downgraded previously protected federal wetlands under the Clean Water Act (CWA). As a result, since 2000, temporal wetlands are left up to the states and non-profit organizations to protect. By examining populations of temporal wetlands in Missouri and Wisconsin, two states that have experienced growths in loss of buffer zones, agriculture, and urbanization a clearer understanding can be gained to determine how effective each state has been with mitigating the effects of habitat loss on amphibians.
