Water Quality Vulnerability in the Ozarks using Landscape Ecology Metrics: Upper White River Browser (v2.0)

The Upper White River study area landscape metric maps provided in this section are based on the inter-decade change of conditions among the early 1970s, 1980s, 1990s, and 2000s (see maps and metadata for additional information). Land-cover maps demonstrate the changes in urban, forest, and agricultural/grassland land-cover types from the early 1970s to the early 1980s; from the early 1980s to the early 1990s; from the early 1990s to the early 2000s; and then a full 30 year summary of change from the early 1970s to the early 2000s. The three decadal views and the summary 30-year change view of land-cover change focuses on land-cover types, which are among the key indicators (using contemporaneous data in the late 1990s and early 2000s) of water-quality vulnerability. Additional analyses of land-cover change are ongoing to improve and expand upon the indicators of water-quality vulnerability provided in v2.0 of the browser.

• Overview of Key Land-Cover Types Used for Change Analyses
  • Examples of urban land-cover are urban centers and small rural towns.
  • Examples of the agricultural/grassland land-cover are pasture, a row crop field, a golf course, or any other area of herbaceous vegetation.
  • Examples of forest land-cover are nature reserves and woodlots.
