Puerto Rico Gap Analysis Project

The Puerto Rico Gap Analysis Project (PRGAP) is a comprehensive assemblage of information on Puerto Rico's land cover, vertebrate occurrences and natural history information, and land stewardship.

It is based on methods developed by the national Gap Analysis Program (GAP) to determine the degree to which animal species and natural communities are represented in the current mix of conservation lands.

The PRGAP provides geographic and ecological information on the status of not only threatened or rare species, but the common species of Puerto Rico.

Those species or communities not well represented are considered conservation "gaps."

IITF-RMAP-01 Urban and rural land use in Puerto Rico
This map identifies three land use regions: Urban, suburban, and rural, and displays (built up) developed surfaces. The classification was made using information on the density of developed land and on human population distribution. The classification can aid in the understanding of how people use and develop the island and serve as a tool in land use planning.
