  1. Restorable area represents grassland land cover within the stream buffer width indicated for the entire 1215-km stream network of Marin County, California. Carbon in Mg C ha−1 represents the sum of modeled biomass and soil estimates at 20 years restoration age. Success rate is calculated as the proportion, by area, of the total area attempted that resulted in successful revegetation. Total is the product of restorable area, Mg C ha−1, and success rate %; low and high estimates are calculated the same way, but use the endpoints of the 95% confidence intervals for the 20-year point estimates for soil C and biomass C
