Percentage of streams affected by cuts vs. fills for five ecoregions
Detailed Description
Percentage of streams affected by cuts vs. fills for five ecoregions. Note that nearly all the streams affected by topographic changes in the Central Appalachians fall within fill polygons, most of which are likely in valley fills from mountaintop mining operations.
See the Significant Topographic Changes in the United States project for more information.
