An oak is a tree or shrub in the genus Quercus of the beech family, Fagaceae. There are approximately 500 extant species of oaks. The common name "oak" also appears in the names of species in related genera, notably Lithocarpus, as well as in those of unrelated species such as Grevillea robusta and the Casuarinaceae (she-oaks). The genus Quercus is native to the Northern Hemisphere, and includes deciduous and evergreen species extending from cool temperate to tropical latitudes in the Americas, Asia, Europe, and North Africa. North America has the largest number of oak species, with approximately 160 species in Mexico of which 109 are endemic and about 90 in the United States. The second greatest area of oak diversity is China, with approximately 100 species.
Quercus kelloggii, the California black oak, also known as Kellogg oak, is an oak in the red oak section, native to western North America. Although genetically separated from them for more than 20 million years, its leaves are remarkably similar in appearance to several other members of the red oak section including the red oak and the black oak found in eastern and central North America.
Maclura pomifera, commonly known as the Osage orange, is a small deciduous tree or large shrub, native to the south-central United States. It typically grows about 8 to 15 metres (30–50 ft) tall. The distinctive fruit, a multiple fruit, is roughly spherical, bumpy, 8 to 15 centimetres (3–6 in) in diameter, and turns bright yellow-green in the fall. The fruits secrete a sticky white latex when cut or damaged. Despite the name "Osage orange", it is not related to the orange. It is a member of the mulberry family, Moraceae. Due to its latex secretions and woody pulp, the fruit is typically not eaten by humans and rarely by foraging animals. Controversial suggestions have been made that it was consumed by extinct Pleistocene megafauna, but these claims have been criticised as lacking empirical evidence.
Quercus alba, the white oak, is one of the preeminent hardwoods of eastern and central North America. It is a long-lived oak, native to eastern and central North America and found from Minnesota, Ontario, Quebec, and southern Maine south as far as northern Florida and eastern Texas. Specimens have been documented to be over 450 years old.
Quercus garryana is an oak tree species of the Pacific Northwest, with a range stretching from southern California to southwestern British Columbia. It is commonly known as the Oregon white oak or Oregon oak or, in Canada, the Garry oak. It grows from sea level to an altitude of 690 feet in the northern part of its range, and from 980 to 5,900 ft in the south of the range in California. The eponymous Nicholas Garry was deputy governor of the Hudson's Bay Company.
The Chequamegon–Nicolet National Forest is a 1,530,647-acre (6,194.31 km2) U.S. National Forest in northern Wisconsin in the United States. Due to logging in the early part of the 20th century, very little old growth forest remains. Some of the trees that grow there today were planted by the Civilian Conservation Corps in the 1930s. The national forest lands contain trees and vegetation corresponding to the North Woods Ecoregion that is prevalent throughout the upper Great Lakes region.
New River State Park is a North Carolina state park in Ashe County, North Carolina in the United States. Located near Jefferson, North Carolina, it covers 3,323 acres (13.45 km2) in the protected New River watershed. The New River is one of the oldest rivers in the United States. It is considered by some geologists to be possibly one of the oldest rivers in the world, between 10 million and 360 million years old. New River State Park is open for year-round recreation, including canoeing, hiking, picnicking, fishing, camping and environmental education. The park is just off U.S. Route 221 in northwestern North Carolina.
The tallgrass prairie is an ecosystem native to central North America. Historically, natural and anthropogenic fire, as well as grazing by large mammals provided periodic disturbances to these ecosystems, limiting the encroachment of trees, recycling soil nutrients, and facilitating seed dispersal and germination. 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 terms "oakery" or "woodlands" are 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.
Rome Sand Plains is a 15,000-acre (61 km2) pine barrens about five miles (8.0 km) west of the city center of Rome in Oneida County in central New York. It consists of a mosaic of sand dunes rising about 50 feet (15 m) above low peat bogs that lie between the dunes. The barrens are covered with mixed northern hardwood forests, meadows, and wetlands. About 4,000 acres (16 km2) are protected in conservation preserves. Pine barrens are typical of seacoasts; the Rome Sand Plains is one of only a handful of inland pine barrens remaining in the United States. A second inland pine barrens, the Albany Pine Bush, is also found in New York, located north and west of state's capital Albany.
Quercus coccinea, the scarlet oak, is a deciduous tree in the red oak section Lobatae of the genus Quercus, in the family Fagaceae.
Natural burial is the interment of the body of a dead person in the soil in a manner that does not inhibit decomposition but allows the body to be naturally recycled. It is an alternative to other contemporary Western burial methods and funerary customs.
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 Appalachian mixed mesophytic forests is an ecoregion of the temperate broadleaf and mixed forests biome, as defined by the World Wildlife Fund. It consists of mesophytic plants west of the Appalachian Mountains in the Southeastern United States.
Joseph E. Ibberson Conservation Area is a 783-acre (317 ha) Pennsylvania state park in Middle Paxton and Wayne Townships, Dauphin County, Pennsylvania in the United States.
Clark State Forest, located just north of Henryville, Indiana in the United States, is Indiana's oldest state forest, formed in 1903 as a forest research facility and a nursery and later expanded by the Works Progress Administration. Originally 2,028 acres (8 km²) of total land area, it is now almost 24,000 acres (100 km2) and is bisected by Interstate 65. It features three trails used exclusively for hikers trails: two internal trails, and the 59-mile (95 km) Knobstone Trail. There are nine horse trails, and five miles (8 km) of mountain bike trails. Two nature preserves are also situated within the forest. The forest also contains a 100-yard (91 m) outdoor gun range.
Zoar Valley is an area of deep gorges along the Main and South branches of Cattaraugus Creek in western New York, United States. The valley is located along the border of Erie County and Cattaraugus County, roughly between the villages of Gowanda to the west and Springville to the east.
Ogdens Cave Natural Area Preserve is a 131-acre (53 ha) Natural Area Preserve located in Frederick County, Virginia. The preserve protects a cave that carries a below-ground branch of Buffalo Marsh Run, which also flows overland through the preserve.
The eastern woodlands 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.
Stephens State Forest is the a state forest located in Lucas, Clarke, Monroe, Appanoose and Davis Counties in Iowa. Stephens State Forest is 15,500 acres and split into 7 separate locations that collectively make up the largest state forest in Iowa.
