| Abstract: |
American forests conducted a Regional Ecosystem Analysis of the Chesapeake Bay Region to determine how the landscape has changed over time. The analysis assessed the value of ecological features using data from satellite images spanning a 24-year period from 1973 to 1997. The analysis covered approximately 11.4 million acres of land in the southeast portion of the Chesapeake Bay watershed and a more detailed study of a 1.5 million acre area in the greater Baltimore-Washington area. The analysis uses Geographic Information Systems (GIS) technology to measure the changing structure of the landscape, with emphasis on tree cover. Regional changes in the landscape are analyzed through remote sensing, while detailed site inventories and economic calculations are created by AMERICAN FORESTS' CITYgreen® software. |
