Vertebrate Distributions for New England Gap Analysis
Personnel: David Capen, Ernest Buford, Peter Williams
Cooperators: New Hampshire Fish and Game Dept., Vermont Fish and Wildlife Dept.
Using a variety of distributional data, we have constructed range maps of New
England's vertebrate species. Sources of data for birds
include statewide Breeding Bird Atlas projects and the Breeding Bird Survey.
Data sources for mammals and for
reptiles and amphibians also include
atlas project data, but also rely heavily on data from Natural Heritage programs.
An example for willow flycatcher illustrates the process of range map development:
You may notice that our range map for willow flycatcher suffers for lack of a detailed land cover map for the final step (because our land-cover map is still in progress, we used the AVHRR forest cover map for this example).
Recent work on vertebrate distributions also includes production of regional range maps that have been smoothed by bioregions (U.S. Forest Service sections and subsections).
