Create shallow-water benthic habitat maps for the marine ecosystem off southwest Puerto Rico, including marine areas adjacent to Natural Reserves in Guanica and Belvedere. These maps will be used to support marine resource management and conservation in the Commonwealth. In addition, the maps will enable change detection in an assessment of the effectiveness of restoration activities on the condition of adjacent coral reef ecosystems.

As part of a baseline characterization of Guanica Bay, Puerto Rico, in support of watershed restoration (http://ccma.nos.noaa.gov/ecosystems/coralreef/guanica.aspx), the Biogeography Branch (BB) updated a benthic habitat map off southwest Puerto Rico, extending from Guanica Bay in the east to Cabo Rojo to the west (Figure 1). In addition, in coordination with the NOAA Fisheries Caribbean Field Office, marine areas adjacent to two Natural Reserves were also mapped. The Guanica Dry Forest Reserve (Bosque Estadal de Guanica) is located adjacent to and east of Guanica Bay. The Reserva Natural Finca Belvedere is located in the municipality of Cabo Rojo off the west coast of Puerto Rico, and covers a coastal area of 256 acres of wetlands.
The mapping effort involves a refinement of existing NOAA benthic habitat maps for the study area. Two major improvements include a reduced minimum mapping unit from one acre to 1000 sq. meters (~1/4 acre) and increased
coverage into areas formerly classified as unknown. In addition, a refined classification scheme was used. The digital map product was produced using a technique known as ‘heads-up digitizing’, where digital satellite imagery was visually interpreted and habitats were then delineated in a hierarchical classification scheme.
