1992 Seagrass and Mangrove Habitats of the Salt River Bay National Historical Park and Ecological Preserve
Habitat maps were created as part of a larger ecological assessment conducted by NOAA's National Ocean Service (NOS), Biogeography Branch, for Salt River Bay National Historic Park and Ecological Preserve (National Park Service).Aerial photographs were obtained for 1992 from the National Geodetic Survey, and were orthorectified by the Biogeography Branch. A classification scheme was set up with 20 benthic habitat types, 19 land cover types, and 13 mangrove habitat types. For this map of seagrass and mangrove habitats during 1992 only the 3 seagrass, and 14 mangrove classification categories were used. These were mapped directly into a GIS system through visual interpretation of orthorectified aerial photographs.

1997-2001 Mangrove Restoration Areas in Salt River Bay National Historical Park and Ecological Preserve, St. Croix, USVI
공공데이터포털
Apart from two 100 m test plots, mangrove restoration activities were conducted between 1997 and 2001. Each year, thousands of red mangrove propagules were planted in three large rectangular plots on the western side of Sugar Bay. In addition to those large plots, a fringe planting of propagules was conducted along much of the eastern shore of Sugar Bay. A small zone of black mangroves was also planted in 2001 although less than 1% survived long term. Detailed methods of restoration activities are available in Riley and Kent 1999 and SEA 2004. Restoration mangroves were not visible in the 2000 imagery due to the small size of individual seedlings. These plots were therefore delineated with the aid of GPS waypoints acquired by walking or kayaking around the perimeter of each plot. GPS positions were used as a guide to digitize the boundaries of the restoration areas and the results are presented.
