Wetlands in NETN are widespread and diverse, ranging from marine to freshwater habitats. Forested freshwater wetlands are the dominant wetland type in most NETN parks. Vernal pools are present in most, if not all NETN parks, but are not mapped as part of the National Wetland Inventory. Of all NETN parks, the greatest diversity and abundance of wetlands are found in Acadia National Park, including considerable coverage of palustrine (inland marshes and swamps as well as bogs, fens, tundra and floodplains)scrub/shrub and emergent habitats. Monitoring permanent freshwater wetlands is a low priority for the National Historical Parks and Sites in NETN, therefore permanent freshwater wetlands are monitored in Acadia NP only. NETN's definition of permanent freshwater wetlands follows the targeted wetland habitats used by the EPA: palustrine emergent, palustrine scrub/shrub, and palustrine forested wetlands. All of these wetland types are characterized as having rooted vegetation, open water less than 1-m deep where present, hydric soils, hydrophytic plants, and wetland hydrology. Assessment areas may include no more than 10% non-wetland area (e.g., upland habitat, deep water, etc).
