Swanton Pacific Ranch contains a variety of habitats for wildlife that include grassland, wetlands, forestland and cultivated land. Wildlife management is an integral component of the activities on the property, and this includes protection, enhancement and management where necessary.

Of crucial importance to wildlife integrity is the existence of corridors or transects between habitat islands to permit migration. The riparian corridors serve as important links in this regard and are also a major source of species diversity.

There is an abundance of wildlife on the property, which in general poses no problems to ranch operations. The exception to this is the feral pig and deer populations that have caused crop damage in the past and continued grassland disturbance.

Coyotes and bobcats and more recently mountain lions are present which can pose a hazard for small domestic animal species.
