Wetlands in the Northeast Temperate Network are widespread and diverse, ranging from marine to freshwater habitats. Forested freshwater wetlands are the dominant wetland type in most network parks. Vernal pools are present in most, if not all parks, but are not mapped as part of the National Wetland Inventory. Of all Northeast Temperate Network 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 the network, therefore permanent freshwater wetlands will be monitored in Acadia NP only. The Northeast Temperate Network's definition of permanent freshwater wetlands follows the targeted wetland habitats used by the Environmental Protection Agency (EPA). EPA's list of targeted wetland habitats includes 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 plant indicators, and wetland hydrology. Assessment areas may include no more than 10% non-wetland area (e.g., upland habitat, deep water, etc).
