Distribution of palustrine wetland classes along a continuum from the upland environment to deep water. DISTRIBUTION OF THE PALUSTRINE SYSTEM Palustrine wetlands comprise a total area of approximately 189,702 acres (75,881 ha), or about 9% of the land and freshwater area of the coastal zone (table 8-2). A total of 13,650 palustrine wetland units have been identified by the NWI project in the characterization area (table 8-3). The number of palustrine wetland units in each of the six coastal regions (which vary greatly in size) ranges from 758 (region 1) to 3323 (region 4). Their total surface area by region ranges from 57,831 acres (23,132 ha) in region 6 to 7096 acres (2838 ha) in region 1 (table 8-2). The palustrine wetlands com- prise between 4% and 13% of the total upland and freshwater area in regions 1 and 6, respectively. Forested wetlands represent 56% of the area of palus- trine wetlands in the coastal zone. They are the most numerous, are generally the largest, and occupy the greatest area in each of the regions. Scrub/shrub wetlands comprise 25% of the palustrine wetlands in the coastal zone. Forested, scrub/shrub, and forested/scrub/shrub mixed wetlands together com- prise more than 88% of the total area of palustrine wetlands in coastal Maine. As these classes in Maine are primarily bogs, the figures reveal the preva- lence of bogs in coastal Maine. The distribution of palustrine wetland classes in each of the towns in coastal Maine is included in appendix A of chapter 2. 8-6
