Pacific Island Network
The NPS Inventory & Monitoring Program monitors changes over time in 14 different resources in the Pacific islands.
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.

Pacific Island National Parks 
As far as federal regulation of marine areas is concerned, let us remember that the sea is a continuous and non-border specific regions. That is to say, sealife moves and is not a stationary object such as a forest. Animals and even plants are going to migrate to an environment that is conducive to their survival.
