Description
Declines in amphibian populations at local, regional and global scales have focused attention on this group of vertebrates. Of the 10 amphibian species in Alberta, seven are listed as "at risk" by provincial or federal agencies. In response to concern about amphibians populations, and a lack of amphibian monitoring in the province, the Researching Amphibian Numbers in Alberta (RANA) program was initiated in 1997 with two main objectives: to collect long-term information on amphibian populations, and to increase public awareness of the importance of amphibians and wetland conservation. Seven RANA sites were established in Alberta and monitored using pitfall trapping at a designated poind within each study area. This report presents an analysis of pitfall trapping data collected between 1997 and 2008.
