Comparisons and Contrasts Among Different Scaled Assessments

Abstract:A comparison of a regional (multi-state) and local (multi-county) scale assessment was done to evaluate similarities and differences in the collection, analysis, and interpretation of landscape data. The study areas included EP A Region 3 a11d a sub-region spanning North and South
Carolina centered around Charlotte and Rockhill. We found that while broad scale data at a watershed unit was useful to regional managers and enabled targeted monitoring and special projects they were of less use at the local level. Local decision makers needed more specific
information in order to address issues such as traffic congestion, vehicle emissions, commuter time, and bringing in new businesses. In order to meet these needs more specialized data and smaller measurement units were required. We found the best unit to use at the local area was aggregated traffic area zones. Additional data needs included a traffic demand model, transit
routes, bike lanes, vehicle miles traveled, and average distance to work In conclusion we found that while larger scale landscape data such as acid deposition, forest fragmentation, urban sprawl, and economic and demographic trends provided information about both regional and local scales a more detailed assessment was required to enable local decision makers to address specific needs.
