Amphibians have been selected as a “vital sign” by several
National Park Service (NPS) Inventory and Monitoring (I&M)
networks. An eight-year amphibian monitoring data set provided
opportunities to examine spatial and temporal patterns in
amphibian breeding richness and wetland desiccation across
Yellowstone and Grand Teton National Parks. Amphibian
breeding richness was variable across both parks, and only 4 of
31 permanent monitoring catchments contained all four widely
distributed species. Annual breeding richness was also variable
through time and fl uctuated by as much as 75% in some years and
catchments. Wetland desiccation was also documented across the
region, but alone did not explain variations in amphibian richness.
High annual variability across the region emphasizes the need for
multiple years of monitoring to accurately describe amphibian
richness and wetland desiccation dynamics.
