Thelypodium Howellii
''Thelypodium howellii'', the Howell's thelypody or Howell's thelypodium, is a rare plant of the Western United States. It is endemic to a relatively small area on the borders of three western States: Oregon, Nevada, and California. Description The ''Thelypodium howellii'' plant is biennial. It is often somewhat hairy, especially near the base, but may be hairless and waxy in texture. It produces a slender, branching, erect stem up to 70 centimeters tall. The leaves are mostly located in a rosette around the base. Leaves located higher on the stem may have clasping bases. The inflorescence is a raceme of widely spaced flowers with greenish white or purplish sepals and pale blue or purple, spoon-shaped petals. The fruit is a silique up to 4.5 centimeters long containing plump brown seeds. Subspecies *''Thelypodium howellii'' subsp. ''howellii'' *''Thelypodium howellii'' subsp.

Sereno Watson
Sereno Watson (December 1, 1826 in East Windsor Hill, Connecticut – March 9, 1892 in Cambridge, Massachusetts) was an American botanist. Graduating from Yale in 1847 in Biology, he drifted through various occupations until, in California, he joined the Clarence King Expedition and eventually became its expedition botanist. Appointed by Asa Gray as assistant in the Gray Herbarium of Harvard University in 1873, he later became its curator, a position he maintained until his death. Watson was elected a Fellow of the American Academy of Arts and Sciences in 1874, and a member of the National Academy of Sciences The National Academy of Sciences (NAS) is a United States nonprofit, non-governmental organization.

Great Basin
The Great Basin is the largest area of contiguous endorheic watersheds, those with no outlets, in North America. It spans nearly all of Nevada, much of Utah, and portions of California, Idaho, Oregon, Wyoming, and Baja California. It is noted for both its arid climate and the basin and range topography that varies from the North American low point at Badwater Basin in Death Valley to the highest point of the contiguous United States, less than away at the summit of Mount Whitney. The region spans several physiographic divisions, biomes, ecoregions, and deserts. Definition The term "Great Basin" is applied to hydrographic, biological, floristic, physiographic, topographic, and ethnographic geographic areas. The name was originally coined by John C. Frémont, who, based on information gleaned from Joseph R. Walker as well as his own travels, recognized the hydrographic nature of the landform as "having no connection to the ocean". The hydrographic definition is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Nevada
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms '' gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thur ...

Endemic Flora Of The United States
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oregon Department Of Fish And Wildlife
The Oregon Department of Fish and Wildlife (ODFW) is a government agency of the U.S. state of Oregon responsible for programs protecting Oregon fish and wildlife resources and their habitats. The agency operates hatcheries, issues hunting and angling licenses, advises on habitat protection, and sponsors public education programs. Its history dates to the 1878 establishment of the office of Columbia River Fish Warden. Since 1931, enforcement of Oregon's Fish and Game laws has been the responsibility of the Oregon State Police rather than separate wardens. Hunting, Fishing, Shellfishing and Wildlife viewing A study was done in 2008 by ODFW and Travel Oregon to find the results of expenditures made throughout Oregon from residents and nonresidents that participated in the economic significance of fishing, hunting, wildlife viewing, and shellfish harvesting in Oregon. Roughly 2.8 million residents and non-residents participated in either hunting, fishing, wildlife viewing, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

United States Forest Service
The United States Forest Service (USFS) is an agency of the U.S. Department of Agriculture that administers the nation's 154 national forests and 20 national grasslands. The Forest Service manages of land. Major divisions of the agency include the Chief's Office, National Forest System, State and Private Forestry, Business Operations, and Research and Development.

Fire Ecology
Fire ecology is a scientific discipline concerned with natural processes involving fire in an ecosystem and the ecological effects, the interactions between fire and the abiotic and biotic components of an ecosystem, and the role as an ecosystem process. Many ecosystems, particularly prairie, savanna, chaparral and coniferous forests, have evolved with fire as an essential contributor to habitat vitality and renewal. Many plant species in fire-affected environments require fire to germinate, establish, or to reproduce. Wildfire suppression not only eliminates these species, but also the animals that depend upon them. Campaigns in the United States have historically molded public opinion to believe that wildfires are always harmful to nature. This view is based on the outdated beliefs that ecosystems progress toward an equilibrium and that any disturbance, such as fire, disrupts the harmony of nature. More recent ecological research has shown, however, that fire is an integral c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
