Estimates were derived by fitting multivariate linear regressions to C values for sample plots (aboveground) and measured soil C (from soil pits) using environmental variables such as elevation, slope, solar radiation, soil taxonomy, normalized differential vegetation index (NDVI) and habitat type in a GIS platform (see methods). Soil C is to 1 m depth; AG = aboveground; aboveground C on wildlands excludes grasslands.
