In 1976, Nevada hosted the first Mountain Lion Workshop (Christensen and Fischer 1976), bringing together research and management personnel from thirteen states and two Canadian provinces. While some study data were presented, the workshop was carried out in a relatively informal setting, with state management reports being emphasized. 5 A receiver and antenna are used to pinpoint a cougar’s location based on the signal emitted from the cougar’s radio collar. Telemetry has provided valuable information on cougar movements, prey use, and social interactions.

Females accompanied by large young kill more frequently. Varies with prey density, habitat type, and terrain. With high prey densities in good habitat, males may use 75–150 sq mi; females 25–50; with prey scarce and scattered, males may range over 700 sq mi or more. Young males (2–3 years of age) may disperse widely, seeking available open territories. Movements of several hundred miles from area of birth have been recorded. Young females tend to settle nearer to their area of birth and may reside next to their mother’s home area.
