Guam and the Northern Mariana Islands ESI: MGT (Management Area Polygons)

This data set contains geographical boundary information for National Park Service properties, wildlife refuges, and other management areas in Guam and the Northern Mariana Islands. Vector polygons in this data set represent the management areas. Location-specific type and source information is stored in relational data tables (described below) designed to be used in conjunction with this spatial data layer.This data set comprises a portion of the Environmental Sensitivity Index (ESI) data for Guam and the Northern Mariana Islands. ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil. The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources. See also the SOCECON (Socioeconomic Resource Points) data layer, part of the larger Guam and Northern Mariana Islands ESI database, for additional human-use information.
