The Redwood National and State Parks together comprise a World Heritage Site, so designated for the rugged coast- lines, streams, rivers, and ancient redwood forests. The parks are mandated to protect this heritage for public inspiration and enjoyment, and to ensure passage unim- paired to future generations. Currently, there are more than 200 species of exotic plants in the Redwood National and State Parks. More than thirty of these are invasive species. At least ten exotic plant species threaten the parks' native species and ecosystems. Exotic plant management is a necessary part of the responsibility to protect our natural heritage. Control of harmful exotic plants requires both a guiding plan and long-term, steadfast commitment. Short-term lapses allow invasive species to expand quickly and to negate previous control efforts. The threat of invasive exotic species will not disappear. Keys to successful control are a systematic approach and consistent follow- up. Controlling invasive exotics is a universal challenge of importance beyond simply the parks. To learn more, when finished here, you may wish to visit other web sites on exotic plant management.
