• Environmental modeling

Modeling the Landscape from an Amphibian
Perspective
Land cover and terrain characteristics can
ameliorate effects from exposure to extreme
temperatures and drying for amphibians. Species
biophysical data can be used to help reclassify
land cover from an amphibian perspective. How
amphibian friendly is the landscape during
different seasons? years? management scenarios?
