Pacific Island Network

Inventory and Monitoring Program

The Inventory and Monitoring Program is a major component of the National Park Service’s strategy to improve park management through greater reliance on scientific information. The Pacific Island Network (PACN) is one of 32 National Park Service Inventory & Monitoring networks of national parks linked by geography and shared natural resource characteristics.

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 historic 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.
