Reptiles and amphibians (herps) represent an important part of aquatic and terrestrial ecosystems. Amphibians in particular are good indicators of environmental change due to their sensitivity to a variety of factors such as pollution, introduced species, drought, habitat destruction, and disease. Herp populations may be affected by these factors and exhibit measurable changes in site occupancy, distribution, abundance, and species richness.
