Forested wetlands are wooded bottomlands covered with shallow, sometimes intermittent waters that are adequate to support wetland-associated plants. Examples of tree species include cottonwood, black or green ash, black willow, swamp white oak, red maple, silver maple, black spruce, larch or tamarack, and northern white cedar. Beaver ponds are included in this category, but streams, rivers, and deeper lakes that do not support emergent vegetation are not.

Open herbaceous wetlands have few or no trees and are dominated by perennial, emergent, herbaceous vegetation, sometimes with shrubs interspersed; like forested wetlands, they also feature shallow or intermittent waters supporting emergent vegetation. Swamps, marshes, bogs, and fens are examples of herbaceous wetlands.

Breeding birds associated with wetlands have generally fared well. More than three times as many species gained Priority 1 blocks as lost blocks between the two atlases.
