Cougar-human Conflict
Agencies reported that sightings were the most common type of cougar-human conflict,
followed by livestock depredation, pet depredation, human encounters, wildlife
predation, and poultry depredation (Fig. 3). When asked which conflicts were considered
common to serious problems, livestock depredation rated highest (71%) followed by pet
depredation (36%), cougar sightings (21%), wildlife predation (14%), and cougar-human
encounters (7%) (Fig. 4). Questions regarding the time of year cougar-human conflicts
occurred yielded mixed results: across all jurisdictions, cougar sightings occurred most
often in summer and winter; reports of wildlife predation was most common in fall and
winter; human encounters occurred throughout the year but showed a significant spike in
summer; livestock depredation was most common in summer; and pet depredation was
most common in winter (Fig. 5).
