The water resources in the park are protected and managed under the Federal Water Pollution Control Act Amendments of 1972, and the Clean Water Act of 1977. NPS Management Policies also require the protection and conservation of water quality in the park.
About 149 exotic (nonnative) plant species are found in the park. Most nonnative species grow in disturbed habitat below 5,500 feet. Their presence is the result of human intervention, not natural migration. About 10% of the species are aggressive, capable of invading undisturbed natural areas and dominating native plant communities.
