The marsh-forest boundary in the Chesapeake Bay was determined by geoprocessing high-resolution (1 square meter) land use and land cover data sets. Perpendicular transects were cast at standard intervals (30 meters) along the boundary within a GIS by repurposing the Digital Shoreline Analysis System (DSAS) Version 5.0, an ArcGIS extension developed by the U.S. Geological Survey. Average and maximum slope values were assigned to each transect from surface elevation data. The same values were also provided as points at the center of the transect where it crossed over the boundary. The slope values across the marsh-forest transition zone and at the boundary itself provide comprehensive data layers for local, state,...
Ellsworth Creek Preserve is being used by The Nature Conservancy to test impacts of three different restoration treatments on eight experimental sub-basins within the watershed. This suite of GIS data is part of the baseline monitoring (data collected prior to treatment) of that experiment and includes information on surveys of migratory forest birds, stream-associated amphibians, stream physical habitat, and forest structure and vegetation. For more information, visit waconservation.org . For summary reports of this data, visit our Ellsworth Creek ConserveOnline Workspace .
