Kern River Valley Invasive Species Information
Staff and volunteers of the Kern River Preserve have spent over a decade fighting invasive species. These efforts have paid off with one of the most native forests in western North America.
Each year staff of the Kern River Preserve, volunteers, and the California Department of Fish & Game spent time eradicating purple loosestrife and perennial pepperweed from Sprague Ranch and nearby South Fork lands.
Each of us can help prevent the spread of invasive plants and animals. You can help by learning which species can become invasive and eradicate these from your own yards. Help to educate your local nurseries about the problem with invasives and get them to stop selling problem plants. Contact your legislator and local agriculture commissioner to make sure no invasives are sold or promoted in your county or town.
