In the United Kingdom, an ancient woodland is a woodland that has existed continuously since 1600 or before in England, Wales and Northern Ireland. Planting of woodland was uncommon before those dates, so a wood present in 1600 is likely to have developed naturally.
The tallgrass prairie is an ecosystem native to central North America. Natural and anthropogenic fire, as well as grazing by large mammals, were historically agents of periodic disturbance, which regulates tree encroachment, recycles nutrients to the soil, and catalyzes some seed dispersal and germination processes. Prior to widespread use of the steel plow, which enabled large scale conversion to agricultural land use, tallgrass prairies extended throughout the American Midwest and smaller portions of southern central Canada, from the transitional ecotones out of eastern North American forests, west to a climatic threshold based on precipitation and soils, to the southern reaches of the Flint Hills in Oklahoma, to a transition into forest in Manitoba.
An oak savanna is a type of savanna-or lightly forested grassland- where oaks are the dominant trees, the term oakery or woodlands is also used commonly, though the former is more prevalent when referencing the Mediterranean area. These savannas were maintained historically through wildfires set by lightning, humans, grazing, low precipitation, and/or poor soil.
The Midewin National Tallgrass Prairie (MNTP) is a tallgrass prairie reserve and United States National Grassland operated by the United States Forest Service. The first national tallgrass prairie ever designated in the U.S. and the largest conservation site in the Chicago Wilderness region, it is located on the site of the former Joliet Army Ammunition Plant between the towns of Elwood, Manhattan and Wilmington in northeastern Illinois. Since 2015, it has hosted a conservation herd of American bison to study their interaction with prairie restoration and conservation.
The Cache River is a 92-mile-long (148 km) waterway in southernmost Illinois, in a region sometimes called Little Egypt. The basin spans 737 square miles (1,910 km2) and six counties: Alexander, Johnson, Massac, Pope, Pulaski and Union. Located at the convergence of four major physiographic regions, the river is part of the largest complex of wetlands in Illinois. The Cache River Wetlands — America's northernmost cypress/tupelo swamp — harbors 91 percent of the state's high quality swamp and wetland communities. It provides habitat for more than 100 threatened and endangered species in Illinois. In 1996, the Cache was designated a Wetland of International Importance by the Ramsar Convention.

Glacial Ridge National Wildlife Refuge was created on October 12, 2004, the 545th National Wildlife Refuge in the United States. Its creation was the result of cooperation between at least 30 agencies or governmental entities. The creation of the refuge was spearheaded by The Nature Conservancy, and the initial endowment of 2,300 acres (9.3 km2) of land was donated by the Conservancy. In light of its planned final size of 37,756 acres (153 km2), it is described by the US Fish and Wildlife Service as "the largest tallgrass prairie and wetland restoration project in U.S. history."
The eastern savannas of the United States covered large portions of the southeast side of the continent until the early 20th century. These were in a fire ecology of open grassland and forests with low ground cover of herbs and grasses.
Black Bayou Lake National Wildlife Refuge is one of five refuges managed in the North Louisiana Refuge Complex and one of 545 refuges in the National Wildlife Refuge System.

The Cosumnes River Preserve is a nature preserve of 46,000 acres (190 km2) located 20 miles (30 km) south of Sacramento, in the US state of California. The preserve protects a Central Valley remnant that once contained one of the largest expanses of oak tree savanna, riparian oak forest and wetland habitat in North America. Agricultural development has changed the landscape from groves of oaks and tule marshes to productive farmlands.
Aiken Canyon Preserve is a 1,621-acre (6.56 km2) Nature Conservancy-managed state property in Colorado. It was first observed and named after Charles Aiken who was a 19th century U.S. surveyor, pioneer and ornithologist who first surveyed Aiken Canyon in the 1870s and identified more than 75 bird species. The preserve consists of foothills, shrub and woodland ecosystems and is 12.4 miles southeast from Colorado Springs located on the eastern slope of the Rampart Range which is within a smaller foothill system of the Front Range. The surrounding mountain ranges of the Rampart Range and Palmer Divide created the nature preserves sustainable ecosystem. There is also a four-mile (6 km)-loop hiking trail on the preserve.

Invereshie and Inshriach is a national nature reserve on the western flank of the Cairngorms in the Highland council area of Scotland. The reserve covers habitats at a range of different altitudes, ranging from Caledonian Forest beside the River Feshie in the west, via bog and open moorland, to an arctic-alpine environment on the Cairngorm plateau. The Munro summit of Sgòr Gaoith (1118 m) lies on the eastern boundary of the reserve. The forested areas of the reserve form part of an expanse of Caledonian pinewood that stretches from Glen Feshie to Abernethy, and which as a whole forms the largest single area of this habitat remaining in Scotland. The reserve is owned and managed jointly by NatureScot and Forestry and Land Scotland (FLS): NatureScot own the Invereshie portion of the reserve and FLS the Inshriach area.
