Forest Area Density Analysis map (FDEN)
The Forest Area Density Analysis map (FDEN) can be used to answer the question: How much forest is surrounded by how much other forest?
Forest area on the FDEN map is colored according to the amount of other forest in a surrounding 15-hectare neighborhood (approximately 37 acres). A place that is not itself forest is colored gray, and a place that is outside the continental United States is colored white. The color of a forest place ranges from red (small amount of forest in the neighborhood) to green (large amount of forest in the neighborhood), with intermediate colors (yellow) indicating forest with intermediate amounts of forest in the neighborhood.
Compare the forest area density in these regional areas selected from the FDEN map:

Note: Differences between the NLCD-FDEN product and Google Earth images are due to different spatial resolutions, date of maps, geographic projections, and definitions of forest. Land cover and forest pattern changes since 2001 are not represented in the 2001 NLCD-FDEN product.
