Invading Exotic Pests: What Can Gardeners Do?

When it comes to the spread of non-native plant and animal pests, the world is truly a smaller place. These intruders threaten the environment and cost billions of dollars annually in lost agricultural production. Because they take advantage of new food sources and have no natural enemies, their populations can literally explode almost overnight.

As gardeners, we are the front lines and can provide valuable assistance to federal, state, and local quarantine officials by spotting and reporting unusual plants and animals. Please browse our links for information about these and other unwelcome visitors to California.

For a comprehensive list of invasive species of particular concern in our area, click here to visit our UC IPM Invasive Species page.
