Long-term rattlesnake population trends in response to land management regime changes

Monitoring of wildlife populations is essential for identifying declines or changes, especially in response to habitat changes or disturbance. By comparing historical and modern populations, we can quantify long-term trends. In this study we are comparing historical data from the mid-1980’s to modern to identify trends within a population of Western rattlesnakes (Crotalus oreganus). During the previous study, the landscape was managed as cattle grazing land with negligible human presence.
