This table contains information on land cover within the watersheds of the study sites. Watershed land use (% natural, % pasture, and % developed) is from the 2011 NLCD, % paved area is calculated from all road and parking lot surfaces (not including sidewalks), imperviousness is the mean of the values within the watershed from the NCLD 2011 Percent Developed Imperviousness dataset and has potential vales ranging from 0 (all area high permeability) to 100 (all area highly impermeable), buffer canopy is the mean of values within 30 meters of the perennial stream channels of a watershed from the NCLD 2011 USFS Tree Canopy cartographic dataset and has potential vales ranging from 0 (no canopy for all buffer area) to 100 (thick canopy for all buffer area), and % carbonate bedrock is calculated from whole rock geochemical analysis from Low and Hewitt (unpublished data). It is linked from this document.
