A population of endangered San Joaquin kit foxes (Vulpes macrotis mutica; SJKF) occurs in the urban environment in the city of Bakersfield, California, and may be important for SJKF conservation.  We used a systematic camera station survey and occupancy analysis to identify suitable habitat for SJKF in Bakersfield and to estimate a conceptual carrying capacity.  We identified high, medium, and low suitability habitat totaling 121 km², 196 km², and 40 km², respectively.  Based on a mean urban kit fox home range size of 0.78 km² and an assumption of two adults in high suitability home ranges and one adult in medium suitability ranges, we estimated the adult carrying capacity in Bakersfield to be 561 foxes.  A carrying capacity of 561 adults would increase the estimated range-wide carrying capacity by as much as 38%.  Adult density estimates derived for the urban SJKF population based on the carrying capacity (1.57/km²) and home range size (2.56/km²) were higher than estimates for foxes in natural habitats.  The urban SJKF population in Bakersfield is substantial and therefore could contribute significantly to conservation and recovery efforts for SJKF.  Given our results, a potential conservation strategy may be to encourage or even establish additional urban SJKF populations.
