Invasive Plant Management Plan and Environmental Assessment
North Cascades National Park Service Complex will implement an integrated pest management program that controls invasive, non-native plants; restores impacted areas; and detects and prevents new infestations. The purpose of the program is to protect the resources and values of the North Cascades ecosystem from the adverse impacts of invasive, non-native plants.
Over 200 non-native plants have been documented within North Cascades National Park Service Complex; however, not every species is invasive. For the purpose of this planning effort, an invasive plant is defined as a non-native species whose introduction does or is likely to cause environmental or economic harm, or harm to human, animal, or plant health. Through this planning effort the park complex has developed a well-rounded program to effectively manage invasive, non-native plants within its boundaries, as well as a strategy to prevent their movement from non-park lands.
