Invasive Plants of California’s Wildlands

“Invasive nonnative plants threaten native species with habitat loss, displacement, and severe population declines, thus seriously reducing biodiversity. Invasive Plants of California’s Wildlands is a tremendous source for land managers and others who are interested in protecting the rich natural heritage of California and surrounding states.”

—John C. Sawhill, former President and CEO, The Nature Conservancy

September 2000 Addendum: Species Name Index

Invasive species–those nonnative organisms that aggressively spread into the landscape–are widely recognized as major threats to biological diversity, second only to direct habitat loss. This book provides specific information about the biology and control of the 78 nonnative plant species that are listed by the California Invasive Plant Council (Cal-IPC) as being of greatest ecological concern in California.

The heart of the book consists of species accounts, each description illustrated with a close-up photo, a habitat photo, and line drawings showing details to aid identification. The text addresses the following questions about each species: How do I recognize it? Where would I find it? Where did it come from and how does it spread? What problems does it cause? How does it grow and reproduce? How can I get rid of it?

Many invasives can be halted or slowed, and in certain circumstances even badly infested areas can be restored. With the help of this book, land managers, volunteer stewards, conservationists, and others concerned with wildlands in the western United States can better understand invasive plants and help combat the damage they do.
