Linking Land-use Projections and Forest Fragmentation Analysis


Book Description

An econometric model of private land-use decisions is used to project land use to 2030 for each county in the continental U.S. On a nat. scale, forest area is projected to increase overall between 0.1 & 0.2% per year between now & 2030. However, forest area is projected to decrease in a majority of regions, including the key forestry regions of the South & the Pacific Northwest Westside. Urban area is projected to increase by 68 million acres, & cropland, pasture, rangeland, & Conservation Reserve Program land is projected to decline in area. Regional econometric models are needed to better represent region-specific economic relationships. County-level models of forest fragmentation indices are estimated for the Western U.S. Illus.
