Aquatic Habitat Protection and Restoration

Restoring native fish populations important both because of their value as a recreational resource for visitors and because of the functions they serve in park ecosystems. Many species of terrestrial and aquatic wildlife rely on fish as a food source. Anadromous fish, which grow and mature in the ocean before returning to spawn in freshwater, are critical to the productivity of many aquatic, riparian and adjacent terrestrial ecosystems.

Many NPS units protect watersheds and aquatic habitats that serve as refuges for healthy populations of native fish species that have declined elsewhere within their ranges. This situation is most typical of parks that are isolated and / or located near the headwaters of large watersheds. In such areas, the protection of habitat is a top priority.
