Figure 1From: Estimating the carbon budget and maximizing future carbon uptake for a temperate forest region in the U.S.Simulated carbon balance for the Chequamegon-Nicolet National Forest (CNNF), 1825–1999. Spatial averages of net biome production, left-hand axis, are shown for the entire CNNF (All, solid line), hardwoods (large dash) and conifer (small dash). Positive values indicate a C sink relative to the atmosphere. Bar graph of simulated annual harvest area in CNNF, right-hand axis, is shown in light grey.Back to article page
