Separate analysis of covariance (ANCOVAs) were run with a general linear model for each of the Pasture–Broadleaf and Broadleaf– Conifer set of paired plots. We modeled total soil carbon (O horizon plus 0–45 cm mineral soil) as well as the difference in total soil carbon between vegetation pairs as a dependent variables in separate analyses. The model results for the whole soil profile model are reported below, except where additional information was gained by analyzing on a per depth basis.
