This data set is based on summaries of observed nesting activities and presence of all bird species monitored by the SCDNR from 2006 through 2010 at several transient washover islands that are critical habitat used by these seabirds for nesting in South Carolina. Numbers are from nest counts or from estimates made from counting adults that appear to be incubating or brooding young. Nests counts were conducted by walking through the colony and counting nests with eggs or chicks. The number of wading bird nests at these sites is also included. Wading bird counts were primarily estimates from counting adults that were assumed to be nesting. Each site was only counted once, thus these numbers may not represent peak numbers of nests at the site. This data does not include all species that nest on a site. For example, laughing gulls, shorebirds, and uncommon species are not included. This data set does not include all sites in SC that have nesting seabirds, thus totaling all nests for a species during one year, may not be the total number of nests in SC for that species.
This GIS data set was created for the purpose of describing the location and types of seabird colonies that nest along the South Carolina coastline so that these nesting activities can be considered for any planned energy development or other coastal use activities.

Due to the transient and constantly changing nature of these island, a single point was used to represent the island. The point was placed on the island in a location that was present on all of the following 1 meter imagery: 2009 NAIP, 2006 DOQQ, 1999 DOQQ, and 1994 DOQQs. Numbers are from nest counts or from estimates made from counting adults that appear to be incubating or brooding young. Nests counts were conducted by walking through the colony and counting nests with eggs or chicks. The number of wading bird nests at these sites is also included. Wading bird counts were primarily estimates from counting adults that were assumed to be nesting.
