Coastal Change Analysis Program Regional Forest Fragmentation
These value-added, raster-based maps of forest fragmentation were produced using Coastal Change Analysis Program (C-CAP) regional land cover data. There are four categories of forest fragmentation mapped: patch, edge, perforated, and core. These categories have been identified as indicators of forest ecosystem quality and can be used to assess the amount of fragmentation present in a landscape and potential habitat impacts. The analysis was performed using the Landscape Fragmentation Tool from the University of Connecticut’s Center for Land Use Education and Research (CLEAR).
Intact forests are ecologically important but are becoming increasingly susceptible to development pressures and conversion. Forest fragmentation is the breaking up of large contiguous forest tracts into smaller, or less contiguous, areas. It is important to look at not only the net change in forest area but also the spatial pattern of the observed changes.
Limitations and Notes
C-CAP data sets are not jurisdictional or intended for use in litigation. While efforts have been made to ensure that these data are accurate and reliable within the limits of current technology, NOAA cannot assume liability for any damages or misrepresentations caused by inaccuracies in the data, or as a result of the data to be used on a particular system. NOAA makes no warranty, expressed or implied, nor does the fact of distribution constitute such a warranty.
