Human-wildlife conflict is a critical conservation challenge. The estimated number of black bears is increasing in California and in Sonoma County. The rise in bear detections in a region with increasing human encroachment into the wildlands creates the potential for human-wildlife conflict. Information about black bears -- such as the population size and growth rate, dispersal patterns, and habitat use -- is needed to guide and prioritize efforts to teach people how to live among bears safely, including guidance on avoiding the kind of attractive nuisances likely to lead to conflict. To evaluate long-term trends within the bear population we used image data recorded at a grid of 20 wildlife cameras at Pepperwood Preserve between 2012-19. The time series data was paired with individual identification using DNA extracted from scat samples collected in 2020. Our image data showed an increase in black bear activity at Pepperwood. Genetic results identified three females and six males, indicating the presence of at least nine bears in 2020. Our findings have informed the outreach efforts of the North Bay Bear Collaborative; a group of agencies, non-profit conservation groups, landowners and individuals, with the aim of fostering human coexistence with an increasing black bear population.
