Integrated Pest Management for Home Gardeners and Landscape Professionals
Wild pigs are not native to North America and were first introduced in California in 1769 by the Spanish missionaries at Mission San Juan Bautista. The missionaries released domestic pigs near the missions in order to take advantage of the rich natural forage resources available. Read Article (Finzel et al 2015).
Managing Rangelands to Benefit CRLF and CTS
Ranches and grazed public lands are vital to the California tiger salamander and the California red-legged frog not just because they have remained undeveloped but because grazing as a land use is compatible with—and to a great extent beneficial for—conservation of both of these rare amphibians.

Natural History of the Ground Squirrels of California (Grinnel 1918)
In the case of the ground squirrels of California, we have a group of mammals which seems to have in many places benefited by human invasion.

Because of the destructiveness of these rodents to the planted crops and native forage upon which man is dependent to a large extent directly or indirectly for his own food supply, the problem of ground squirrel control has become one of very immediate agricultural and pastoral importance.
