Environment Of Wyoming
Wyoming straddles the Continental Divide, and its abrupt topographic relief includes alternating basins and mountain ranges. Major mountain ranges include the Beartooth, Gros Ventre, Teton, Wind River, Bighorn, Sierra Madre, and Medicine Bow. Internal basins and eastern plains are rolling to flat, and in the east are the Great Plains. Typical vegetation includes sagebrush, greasewood, and saltbush shrubs in the intermountain basins, grasses on the Great Plains, juniper and mountain mahogany in the foothills, and forest and alpine meadows in the mountains. The state lies within the US Environmental Protection Agency's Region 8. Agriculture in Wyoming The state of Wyoming, also known as the Cowboy State, has 30.2 million acres dedicated to farm land alone.

Saltbush
Saltbush is a vernacular plant name that most often refers to ''Atriplex'', a genus of about 250 plants distributed worldwide from subtropical to subarctic regions. ''Atriplex'' species are native to Australia, North and South America, and Eurasia. Many ''Atriplex'' species are halophytes and are adapted to dry environments with salty soils. The genus ''Chenopodium'' is taxonomically a cousin of the genus ''Atriplex''. Certain chenopodiums may be called saltbushes, including '' C. robertianum'' and '' C. nutans''. ''Sarcobatus vermiculatus'', native to North America, is a halophyte plant, and is sometimes informally called a saltbush.

List Of Superfund Sites In Wyoming
This is a list of Superfund sites in Wyoming designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law. The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations.P.L. 96-510, (), December 11, 1980. These locations are known as Superfund sites, and are placed on the National Priorities List (NPL). The NPL guides the EPA in "determining which sites warrant further investigation" for environmental remediation. As of March 26, 2010, there were two Superfund sites on the National Priorities List in Wyoming. No other sites are currently proposed for entry on the list, and one site has been cleaned up and removed from the NPL.

Environmental Issues In Wyoming
The U.S. state of Wyoming faces a broad array of environmental issues stemming from natural resource extraction, species extirpation, non-native species introduction, and pollution. Wildlife species that have been affected by these issues include: * Gray wolf (''Canis lupus''), locally extirpated * Grizzly bear (''Ursus arctos horribilis'') * Lodgepole pine (''Pinus contorta''), affected by mountain pine beetles, which threaten to disrupt forests in Wyoming * Greater sage grouse (''Centrocercus urophasianus''), affected by natural gas extraction. * Wyoming toad (''Anaxyrus baxteri''), extinct in the wild Within the state organizations and governments are working to combat these environmental threats and restore balance to the ecology. Protection of some of these species has proven controversial. Natural resource extraction Wyoming is a resource rich state with a history of boom and bust cycles. The 1970s energy crisis initiated a coal-mining boom in Wyoming that lasted until the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
US Environmental Protection Agency
The Environmental Protection Agency (EPA) is an independent executive agency of the United States federal government tasked with environmental protection matters. President Richard Nixon proposed the establishment of EPA on July 9, 1970; it began operation on December 2, 1970, after Nixon signed an executive order. The order establishing the EPA was ratified by committee hearings in the House and Senate. The agency is led by its administrator, who is appointed by the president and approved by the Senate. The current administrator is Michael S. Regan. The EPA is not a Cabinet department, but the administrator is normally given cabinet rank. The EPA has its headquarters in Washington, D.C., regional offices for each of the agency's ten regions and 27 laboratories. The agency conducts environmental assessment, research, and education. It has the responsibility of maintaining and enforcing national standards under a variety of environmental laws, in consultation with state, triba ...

Alpine Meadow
Alpine tundra is a type of natural region or biome that does not contain trees because it is at high elevation, with an associated harsh climate. As the latitude of a location approaches the poles, the threshold elevation for alpine tundra gets lower until it reaches sea level, and alpine tundra merges with polar tundra. The high elevation causes an adverse climate, which is too cold and windy to support tree growth. Alpine tundra transitions to sub-alpine forests below the tree line; stunted forests occurring at the forest-tundra ecotone are known as ''Krummholz''. With increasing elevation it ends at the snow line where snow and ice persist through summer. Alpine tundra occurs in mountains worldwide. The flora of the alpine tundra is characterized by dwarf shrubs close to the ground. The cold climate of the alpine tundra is caused by adiabatic cooling of air, and is similar to polar climate. Geography Alpine tundra occurs at high enough altitude at any latitude. Portions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mahogany
Mahogany is a straight-grained, reddish-brown timber of three tropical hardwood species of the genus ''Swietenia'', indigenous to the AmericasBridgewater, Samuel (2012). ''A Natural History of Belize: Inside the Maya Forest''. Austin: University of Texas Press. pp. 164–165. . and part of the pantropical chinaberry family, Meliaceae. Mahogany is used commercially for a wide variety of goods, due to its coloring and durable nature. It is naturally found within the Americas, but has also been imported to plantations across Asia and Oceania. The mahogany trade may have begun as early as the 16th century and flourished in the 17th and 18th centuries. In certain countries, mahogany is considered an invasive species. Description The three species are: *Honduran or big-leaf mahogany ('' Swietenia macrophylla''), with a range from Mexico to southern Amazonia in Brazil, the most widespread species of mahogany and the only genuine mahogany species commercially grown today.

Juniper
Junipers are coniferous trees and shrubs in the genus ''Juniperus'' () of the cypress family Cupressaceae. Depending on the taxonomy, between 50 and 67 species of junipers are widely distributed throughout the Northern Hemisphere, from the Arctic, south to tropical Africa, throughout parts of West Asia, western, Central Asia, central and South Asia, southern Asia, east to eastern Tibet in the Old World, and in the mountains of Central America. The highest-known juniper forest occurs at an altitude of in southeastern Tibet and the northern Himalayas, creating one of the highest tree lines on earth. Description Junipers vary in size and shape from tall trees, tall, to columnar or low-spreading shrubs with long, trailing branches. They are evergreen with needle-like and/or scale-like leaves. They can be either monoecious or dioecious. The female Conifer cone, seed cones are very distinctive, with fleshy, fruit-like coalescing scales which fuse together to form Juniper berry, a&n ...

Shrub
A shrub (often also called a bush) is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some definitions state that a shrub is less than and a tree is over 6 m. Others use as the cut-off point for classification. Many species of tree may not reach this mature height because of hostile less than ideal growing conditions, and resemble a shrub-sized plant. However, such species have the potential to grow taller under the ideal growing conditions for that plant. In terms of longevity, most shrubs fit in a class between perennials and trees; some may only last about five y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sarcobatus
''Sarcobatus'' is a North American genus of two species of flowering plants, formerly considered to be a single species. Common names for ''S. vermiculatus'' include greasewood, seepwood, and saltbush. Traditionally, ''Sarcobatus'' has been treated in the family Chenopodiaceae, but the APG III system of 2009 recognizes it as the sole genus in the family Sarcobataceae. Name In Greek, ''sarco'' means 'fleshy' (probably in reference to the fleshy leaves) and batus means 'bramble' (referring to the spiny branches). Description The ''Sarcobatus'' plants are deciduous shrubs growing to 0.5–3 metres tall with spiny branches and green succulent leaves, 10–40 mm long and 1–2 mm broad. The leaves are green, in contrast to the grey-green color of most of the other shrubs within its range. The flowers are unisexual, with the male and female flowers on the same plant and appear from June to August. The species reproduces from seeds and sprouts. ''S. vermicu ...

Continental Divide Of The Americas
The Continental Divide of the Americas (also known as the Great Divide, the Western Divide or simply the Continental Divide; ) is the principal, and largely mountainous, hydrological divide of the Americas. The Continental Divide extends from the Bering Strait to the Strait of Magellan, and separates the watersheds that drain into the Pacific Ocean from those river systems that drain into the Atlantic and (in northern North America) Arctic oceans (including those that drain into the Gulf of Mexico, the Caribbean Sea and Hudson Bay). Although there are many other hydrological divides in the Americas, the Continental Divide is by far the most prominent of these because it tends to follow a line of high peaks along the main ranges of the Rocky Mountains and Andes, at a generally much higher elevation than the other hydrological divisions. Geography Beginning at the westernmost point of the Americas’ mainland (Cape Prince of Wales, just south of the Arctic Circle), the Conti ...
