Bird Density and Marine Mammal Counts Based on 7700 Meter Bins in Southern California, 1999-2002 Tracklines and associated observations were mapped and analyzed using ArcMap (ESRI, Redlands, CA). GPS data were recorded in NAD27 map datum and projected to an USGS Albers Equal Area Conic map projection for presentation and subsequent density analyses. Concatenated GPS and observation data were then used to generate point and line coverages in ArcMap (ESRI, Redlands, CA). We designed a custom analytic tool using ArcMap Model Builder that allows for the construction and export of user-specified and effort-adjusted spatial binning of species observations along continuous trackines. For the purposes of this report, we calculated seabird density estimates and marine mammal counts along continuous 3.0-kilometer and...

However, the existing maps of these resources were created at different scales and are housed in a variety of locations. This can be challenging for users and limits their utility for a regional approach to analysis. Looking across boundaries is important to understanding relative value when making habitat conservation decisions. With this project, The Nature Conservancy (TNC) proposes to: (1) develop a suite of regional natural resource maps for the South Atlantic; (2) create a report describing data source, analytical methods and mapping results that includes a summary of...
