Estimating sizes of wild pig populations in the North and Central Coast regions of California
Article Abstract:
Variation in climate, habitats and predator densities may combine to produce differences in the population biology of wild pigs in the North and Central Coast regions of California. Hunting may lead to a substantial reduction in the density of wild pig populations.

Range expansion, population sizes, and management of wild pigs in California
Article Abstract:
There were around 133,000 wild pigs in California in 1996. It is possible that wild pigs have saturated the range of appropriate habitat available to them, and that their numbers will therefore not rise much more. However, it is also possible that the halt in the growth of wild pig numbers seen in the late 1980s and early 1990s is only temporary. The California Dept of Fish and Game has mainly sought to control wild pig numbers through hunting. It is not possible to eliminate wild pigs from large mainland regions, so control efforts must focus on understanding and reducing the ecological impact of wild pigs.

Range expansion, population sizes, and management of wild pigs in California
Article Abstract:
The home range expansion and population sizes of wild pigs in California were investigated to determine their effects on the ecology of mainland areas. Data from Game Take Hunter Surveys were analyzed to assess relative population densities within the range of wild pigs and to derive semiquantitative estimates of the numbers of wild pigs in different regions in California. It was found that the increase in the home range of wild pigs in the state was caused by a combination of deliberate releases of domestic pigs, multiple hunting-related introductions and possibly, increased forage availability related to agricultural development.
