The Areas for Sensitive Terrapin Nesting Sites dataset represents all areas in the Coastal Bays Watershed that have been observed as nesting sites for terrapins as well as those areas that are excellent potential areas for nesting - i.e.. sandy beaches. All areas are ranked for sensitivity by the Sensitive Areas Taskforce - conviened by the MD Dept. of Natural Resources Water Use Committee. The dataset was created by combining the sandy beach areas compiled by MD Geologic Survey from the MD Wetland Guidance Map shoreline data and information given to staff by Mr. Jim Casey of the MD DNR Fisheries Division of the observed nesting sites.Feature Service Link:http://geodata.md.gov/imap/rest/services/Biota/MD_LivingResources/FeatureServer/2 ADDITIONAL LICENSE TERMS: The Spatial Data and the information therein (collectively "the Data") is provided "as is" without warranty of any kind either expressed implied or statutory.

The vector format was created from the SHA Shoreline file and graphic representations in the Lippson book (See bibliography below). These areas were then overlane with a point file created from lat/long collected during the surveys conducted by O'dell - Mowrer - and Uphoff of MD DNR Fisheries Service. This was done to verify that the graphic representations were accurate. These data sets were then converted to raster format and reclassified with a rank determined by DNR biologists. This rank determines level of habitat importance with spawning areas ranking highest and adult areas of bay depth below 3 feet ranking the lowest. These ranked rasters were then stacked and an output raster was created showing areas of high habitat diversity. These rasters were then clipped by county.

The Sensitive Areas Horseshoe Crab dataset shows areas within Maryland's Coastal Bays that are significant for Horseshoe Crab breeding populations. Horseshoe Crabs use sandy beach areas for breeding. The coverage differentiates potential breeding habitat (hcrab_rank=3) from confirmed breeding locations (hcrab_rank=5).Feature Service Link:http://geodata.md.gov/imap/rest/services/Biota/MD_LivingResources/FeatureServer/4 ADDITIONAL LICENSE TERMS: The Spatial Data and the information therein (collectively "the Data") is provided "as is" without warranty of any kind either expressed implied or statutory.

The areas in this data set were determined from USGS Terrapin studies (for more information contact Paula Henry - 410-465-0550 or paula.henry@usgs.gov) - DNR studies conducted by Margaret Whilden - and a terrapin study conducted by Willem Roosenburg (contact information can be acquired from Harley Speir of DNR Fisheries Service). For extent acquracies please contact the project lead for each study. Secondary habitats were delineated using sandy beach data from VIMS and salinity data from Lee Karrh of DNR. Sandy beach areas were selected and exported from the source file and then combined with the salinity data to determine sensitivity importance levels. These data sets were then converted to raster format and reclassified with a rank determined by DNR biologists. This rank determines level of habitat importance with spawning areas ranking highest and adult areas of bay depth below 3 feet ranking the lowest.
