Eucalyptus is a genus of more than 700 species of flowering plants in the family Myrtaceae. Most species of Eucalyptus are trees, often mallees, and a few are shrubs. Along with several other genera in the tribe Eucalypteae, including Corymbia and Angophora, they are commonly known as eucalypts. Plants in the genus Eucalyptus have bark that is either smooth, fibrous, hard or stringy, the leaves have oil glands, and the sepals and petals are fused to form a "cap" or operculum over the stamens. The fruit is a woody capsule commonly referred to as a "gumnut".
Pinus radiata, the Monterey pine, insignis pine or radiata pine, is a species of pine native to the Central Coast of California and Mexico. It is an evergreen conifer in the family Pinaceae.
Platanus occidentalis, also known as American sycamore, American planetree, western plane, occidental plane, buttonwood, and water beech, is a species of Platanus native to the eastern and central United States, the mountains of northeastern Mexico, extreme southern Ontario, and possibly extreme southern Quebec. It is usually called sycamore in North America, a name which can refer to other types of trees in other parts of the world. The American sycamore is a long-lived species, typically surviving at least 200 years and likely as long as 500–600 years.
The longleaf pine is a pine species native to the Southeastern United States, found along the coastal plain from East Texas to southern Virginia, extending into northern and central Florida. In this area it is also known as "yellow pine" or "long leaf yellow pine", although it is properly just one out of a number of species termed yellow pine. It reaches a height of 30–35 m (98–115 ft) and a diameter of 0.7 m (28 in). In the past, before extensive logging, they reportedly grew to 47 m (154 ft) with a diameter of 1.2 m (47 in). The tree is a cultural symbol of the Southern United States, being the official state tree of Alabama. This particular species is one of the eight pine tree species that falls under the "Pine" designation as the state tree of North Carolina.
Urban forestry is the care and management of single trees and tree populations in urban settings for the purpose of improving the urban environment. Urban forestry involves both planning and management, including the programming of care and maintenance operations of the urban forest. Urban forestry advocates the role of trees as a critical part of the urban infrastructure. Urban foresters plant and maintain trees, support appropriate tree and forest preservation, conduct research and promote the many benefits trees provide. Urban forestry is practiced by municipal and commercial arborists, municipal and utility foresters, environmental policymakers, city planners, consultants, educators, researchers and community activists.
Picea sitchensis, the Sitka spruce, is a large, coniferous, evergreen tree growing to almost 100 meters (330 ft) tall, with a trunk diameter at breast height that can exceed 5 m (16 ft). It is by far the largest species of spruce and the fifth-largest conifer in the world, and the third-tallest conifer species. The Sitka spruce is one of the few species documented to exceed 90 m (300 ft) in height. Its name is derived from the community of Sitka in southeast Alaska, where it is prevalent. Its range hugs the western coast of Canada and the US, continuing south into northernmost California.
The emerald ash borer, also known by the acronym EAB, is a green buprestid or jewel beetle native to north-eastern Asia that feeds on ash species. Females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years. In its native range, it is typically found at low densities and does not cause significant damage to trees native to the area. Outside its native range, it is an invasive species and is highly destructive to ash trees native to Europe and North America. Before it was found in North America, very little was known about emerald ash borer in its native range; this has resulted in much of the research on its biology being focused in North America. Local governments in North America are attempting to control it by monitoring its spread, diversifying tree species, and through the use of insecticides and biological control.
Tsuga canadensis, also known as eastern hemlock, eastern hemlock-spruce, or Canadian hemlock, and in the French-speaking regions of Canada as pruche du Canada, is a coniferous tree native to eastern North America. It is the state tree of Pennsylvania. Eastern hemlocks are widespread throughout much of the Great Lakes region, the Appalachian Mountains, the Northeastern United States, and Maritime Canada. They have been introduced in the United Kingdom and mainland Europe, where they are used as ornamental trees.
Ailanthus altissimaay-LAN-thəss al-TIH-sim-ə, commonly known as tree of heaven, Ailanthus, varnish tree, copal tree, stinking sumac, Chinese sumac, paradise tree, or in Chinese as chouchun, is a deciduous tree in the family Simaroubaceae. It is native to northeast and central China, and Taiwan. Unlike other members of the genus Ailanthus, it is found in temperate climates rather than the tropics.
Taxodium distichum is a deciduous conifer in the family Cupressaceae. It is native to the southeastern United States. Hardy and tough, this tree adapts to a wide range of soil types, whether wet, salty, dry, or swampy. It is noted for the russet-red fall color of its lacy needles.
The Donald E. Davis Arboretum, in Auburn, Alabama, United States, is a public native plants museum, and botanical arboretum with educational facilities, event spaces, and a conservation program. Its grounds, covering 13.5 acres of Auburn University's campus, include cataloged living collections of associated tree and plant communities representative of Alabama's ecosystems, among which is mixed oak forest, carnivorous bog, and longleaf pine savanna. The living collections include more than 1,000 plant types, including 500 different plant species, with over 3,000 cataloged specimens. The Arboretum contains over a mile (2 km) of interwoven walking trails that meander through various southeastern biotopes.
Ulmus pumila, the Siberian elm, is a tree native to Asia. It is also known as the Asiatic elm and dwarf elm, but sometimes miscalled the 'Chinese elm'. U. pumila has been widely cultivated throughout Asia, North America, Argentina, and southern Europe, becoming naturalized in many places, notably across much of the United States.
The National Register of Champion Trees is a list of the largest tree specimens found in the United States as reported to American Forests by the public. A tree on this list is called a National Champion Tree.
American Forests is a 501(c)(3) non-profit conservation organization, established in 1875, and dedicated to protecting and restoring healthy forest ecosystems. The current headquarters are in Washington, D.C.
Lantana camara is a species of flowering plant within the verbena family (Verbenaceae), native to the American tropics. It is a very adaptable species, which can inhabit a wide variety of ecosystems; once it has been introduced into a habitat it spreads rapidly; between 45ºN and 45ºS and more than 1,400 metres in altitude.
The United Kingdom, being in the British Isles, is ideal for tree growth, thanks to its mild winters, plentiful rainfall, fertile soil and hill-sheltered topography. In the absence of people, much of Great Britain would be covered with mature oaks, except for Scotland. Although conditions for forestry are good, trees do face damage threats arising from fungi, parasites and pests. The development of afforestation and the production and supply of timber in Wales come under Natural Resources Wales, as set out in the Forestry Act 1967.
Invasive species are a significant threat to many native habitats and species of the United States and a significant cost to agriculture, forestry, and recreation. The term "invasive species" can refer to introduced/naturalized species, feral species, or introduced diseases. Some introduced species, such as the dandelion, do not cause significant economic or ecologic damage and are not widely considered as invasive. Economic damages associated with invasive species' effects and control costs are estimated at $120 billion per year.
The Arkansas Champion Tree Program is a listing of the largest known specimens of particular tree species in the U.S. state of Arkansas. It is updated every five years by the Arkansas Forestry Commission. The program was modeled on the National Register of Big Trees, started by the American Forests organization in 1940. The goal of Arkansas's program is to record, heighten awareness of, and preserve the largest tree specimens in the state. It uses the same formula for recording tree specimens that was developed by American Forests. Former champions are removed from the list as new, larger, champions are identified and recorded. The program had a total of 130 Champion Trees listed.
Quercus sinuata var. sinuata, commonly called Durand oak, is a variety of Quercus sinuata, a species of oak tree that grows in parts of the southern United States and northeastern Mexico.
