Figure 6-2: Forest cover increase and abandonment of marginal agricultural lands in Grand Traverse County, Michigan. Analyses of the upper Midwestern United States show an increase in forest cover since 1970. This increase results in greater carbon sequestration because forest cover is primarily replacing pastures and croplands. The left image illustrates land-use change by parcel interpreted from aerial photographs. Green colors are forest, beige/yellow is agriculture, and pink color is residential development. The right image is forest cover from Landsat MSS satellite images. Green is forest and light yellow is not forest. The images illustrate the forest regrowth that is occurring across the Upper Midwest concurrently with parcel fragmentation, agricultural abandonment, and rural residential development.
