Classification of watershed vulnerability to wetland impacts from climate change was based on the
proportions of total wetland and acid wetland within the National Forest boundary of each HUC-6 (Figure
10). Three risk categories were established for both total and acid wetlands. The percentage of total
wetland area ranged from 0 to 55.8 percent. Those with less than 10 percent were rated low, 10 to 30
percent were rated moderate, and greater than 30 percent were rated high. Acid wetland ranged from 0 to
42.8 percent of the area for all HUC-6s. Those with less than 5 percent were rated low, 5 to 15 percent
were rated moderate, and greater than 15 percent were rated high. These two risk classes were combined
to form one vulnerability classification for each watershed, as indicated in Table 2.
