A beech–maple forest or a maple beech forest is a climax mesic closed canopy hardwood forest. It is primarily composed of American beech and sugar maple trees which co-dominate the forest and which are the pinnacle of plant succession in their range. A form of this forest was the most common forest type in the Northeastern United States when it was settled by Europeans and remains widespread but scattered today.
Big Woods refers to a type of temperate hardwood forest ecoregion found in western Wisconsin and south-central Minnesota. "Big Woods" is a direct translation of the name given to the region by French explorers: Grand Bois.
The Bottomland hardwood forest is a type of deciduous and evergreen hardwood forest found in US broad lowland floodplains along large rivers and lakes. They are occasionally flooded, which builds up the alluvial soils required for the gum, oak and bald cypress trees that typically grow in this type of biome. The trees often develop unique characteristics to allow submergence, including cypress knees and fluted trunks, but can not survive continuous flooding.
California mixed evergreen forest is an plant community found in the mountain ranges of California and southwestern Oregon.

The eastern forest–boreal transition is a temperate broadleaf and mixed forests ecoregion of North America, mostly in eastern Canada. It is a transitional zone or region between the predominantly coniferous Boreal Forest and the mostly deciduous broadleaf forest region further south.

The Eastern Great Lakes and Hudson Lowlands region extends along the south shores of Lake Erie and Lake Ontario and the St. Lawrence River to Lake Champlain, and south down the Hudson River. It is primarily within the state of New York, with smaller portions in Vermont, Pennsylvania, and Ohio. In the north it meets the Mixedwood Plains Ecozone of Canada. It is mostly temperate deciduous forest and agricultural land.
The Eastern Great Lakes lowland forests is a temperate broadleaf and mixed forest ecoregion of North America, as defined by the World Wildlife Fund. It lies mostly in south and eastern Ontario and Quebec in Canada, and Upstate New York in the United States.

The Southern Great Lakes lowland forests is a temperate broadleaf and mixed forest ecoregion of North America, as defined by the World Wildlife Fund. Located near the Great Lakes, it lies mostly in the central northeastern United States and extends into southeast central Canada. In modern times, little of it remains intact due to land use, including agriculture and urban uses.

Hammock is a term used in the southeastern United States for stands of trees, usually hardwood, that form an ecological island in a contrasting ecosystem. Hammocks grow on elevated areas, often just a few inches high, surrounded by wetlands that are too wet to support them. The term hammock is also applied to stands of hardwood trees growing on slopes between wetlands and drier uplands supporting a mixed or coniferous forest. Types of hammocks found in the United States include tropical hardwood hammocks, temperate hardwood hammocks, and maritime or coastal hammocks. Hammocks are also often classified as hydric, mesic or xeric. The types are not exclusive, but often grade into each other.

The Interior Low Plateaus are a physiographic region in eastern United States. It consists of a diverse landscape that extends from north Alabama across central Tennessee and Kentucky into southern Illinois, Indiana, and Ohio. Its natural communities are a matrix of temperate forests, woodlands, and prairies.

Laurel forest, also called laurisilva or laurissilva, is a type of subtropical forest found in areas with high humidity and relatively stable, mild temperatures. The forest is characterized by broadleaf tree species with evergreen, glossy and elongated leaves, known as "laurophyll" or "lauroid". Plants from the laurel family (Lauraceae) may or may not be present, depending on the location.

The Laurentian Mixed Forest Province, also known as the North Woods, is a forested ecoregion in eastern North America. Among others, this terminology has been adopted by the Minnesota Department of Natural Resources. Similar, though not necessarily entirely identical regions, are identified by the United States Environmental Protection Agency as Northern Lakes and Forests, and by the World Wildlife Fund by regions such as the Western Great Lakes forests and Eastern forest-boreal transition.

The Mississippi lowland forests are a temperate broadleaf and mixed forest ecoregion in the eastern United States, covering an area of 112,300 km2 (43,400 sq mi).

The Northeastern coastal forests are a temperate broadleaf and mixed forests ecoregion of the northeast and middle Atlantic region of the United States. The ecoregion covers an area of 34,630 sq miles (89,691 km2) encompassing the Piedmont and coastal plain of seven states, extending from coastal southwestern Maine, southeastern New Hampshire, eastern Massachusetts, and Rhode Island, southward through Connecticut, New York State, New Jersey, southeast Pennsylvania, Delaware and Maryland.

The northern hardwood forest is a general type of North American forest ecosystem found over much of southeastern and south central Canada, Ontario and Quebec, extending south into the United States in northern New England, New York, and Pennsylvania, and west along the Great Lakes to Minnesota and western Ontario. Some ecologists consider it a transitional forest because it contains species common to both the oak-hickory forest community to the south and the Boreal forest community to the north. The trees and shrub species of the Northern Hardwood Forest are known for their brilliant fall colors, making the regions that contain this forest type popular fall foliage tourist destinations.

An oak forest is a plant community with a tree canopy dominated by oaks. In terms of canopy closure, oak forests contain the most closed canopy, compared to oak savannas and oak woodlands.

The Ozark Mountain forests are a temperate broadleaf and mixed forests ecoregion of the central United States delineated by the World Wide Fund for Nature. The ecoregion covers an area of 23,900 square miles in northern Arkansas and eastern Oklahoma.

The Southeastern mixed forests are an ecoregion of the temperate broadleaf and mixed forest biome, in the lower portion of the Eastern United States.
The Tallgrass Aspen Parkland is an ecoregion located in southeastern Manitoba and northwestern Minnesota. The area is characterized by a mosaic of habitat types, including tallgrass prairie, aspen woodland, sedge meadow wetlands, riparian woodland, and oak savanna. A number of endangered and threatened species occur in the area, including the western prairie fringed orchid and Dakota skipper. One of Minnesota's only wild elk herds utilizes the area as well.

The Upper Midwest forest–savanna transition is a terrestrial ecoregion that is defined by the World Wildlife Fund. An oak savanna plant community located in the Upper Midwest region of the United States, it is an ecotone between the tallgrass prairies to the west and the temperate deciduous forests to the east. A part of the Upper Mississippi River basin, it is considered endangered with less than 5% of the original ecosystem remaining intact, due mostly to overgrazing and conversion to agriculture.

The Western Allegheny Plateau is an ecoregion of the Temperate broadleaf and mixed forests Biome, located on the western Allegheny Plateau and in the Appalachia region of the Eastern United States.

The Western Great Lakes forests is a terrestrial ecoregion as defined by the World Wildlife Fund. It is within the temperate broadleaf and mixed forests biome of North America, in northern areas of the United States' states of Michigan, Wisconsin and Minnesota, and southern areas of the Canadian provinces of Ontario and Manitoba.
