Utilization of air photo interpretation to locate prairie rattlesnake (Crotalus viridis viridis) hibernacula in the South Saskatchewan River Valley

Description

Current anecdotal evidence suggests that the distribution and abundance of the prairie rattlesnake is declining. Due to a lack of standardized information, a means of conducting a landscape level hibernacula inventory and population assessment of rattlesnakes in Alberta must be developed. Previous work undertaken by Alberta Environment was done to attempt to facilitate this process. This method used air photo interpretation and the ecological land classification system to classify a portion of the South Saskatchewan River valley for the likelihood of containing snake hibernacula. This method was evaluated for effectiveness by conducting ground searches throughout the identified study area and correlating actual locations of confirmed hibernacula to predicted locations. A total of eight hibernacula were confirmed.
