EXOTIC PLANT MANAGEMENT
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
