The Pacific Island Network (PACN) Inventory and Monitoring Program (I&M) is one of 32 National Park Service I&M Networks across the country facilitating collaboration, information sharing, and economies of scale in natural resources monitoring. Spanning islands in American Samoa, Guam, the Northern Mariana archipelago, and Hawaii, the Pacific Island Network encompasses an area as large as the continental United States.

The islands and near-shore marine areas within the National Park System protect a wealth of the planet's aquatic and terrestrial biodiversity, unique geologic features, and cultural sites. Isolated from the continental land-masses, these federally protected areas share similarities, including threats from invasive species, limited land area, and finite resources inherent on islands.

This web site delivers information about these resources and how the Inventory & Monitoring Program collects and manages data for Pacific island parks.
