Bruchia Bolanderi
''Bruchia bolanderi'' (known as Bolander's candlemoss or Bolander's pygmymoss) is a rare plant of the Western U.S.: Oregon, California, and Nevada. It grows on very damp bare soil. One may distinguish it from other mosses by the capsules, which are shaped like little upside-down pear fruits. Technical description The plants are tiny, erect, and acrocarpous, with stems and capsules together only 5.1–12 mm tall. The leaves are short, costate (but awn not filled by costa), linear, narrowly acuminate to subulate, serrulate, and green to light brown in color. The ''seta'' are straight, long-exserted, and 1.6–5.4 mm. long, usually longer than 3 mm. The ''hypophysis'' are as long as the urn. The capsules' are the most conspicuous part of the plants, and are long exserted above the perichaetial leaves, and tend to be 1.9–3.0 mm long, light brown, beige to greyish at maturity, widest at the rounded top, with a long tapering neck. The ''calyptra'' is smoot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aulacomnium Palustre
''Aulacomnium palustre'', the bog groove-moss or ribbed bog moss, is a moss that is nearly cosmopolitan in distribution. It occurs in North America, Hispaniola, Venezuela, Eurasia, and New Zealand. In North America, it occurs across southern arctic, subboreal, and boreal"boreal" refers to northern coniferous forests where permafrost occurs only sporadically. regions from Alaska and British Columbia to Greenland and Quebec. Documentation of ribbed bog moss's distribution in the contiguous United States is probably incomplete. It is reported sporadically south to Washington, Wyoming, Georgia, and Virginia. Habitat types and plant communities Ribbed bog moss is frequent in arctic to subboreal wetlands. Moss assemblages are typically diverse in northern (arctic, subarctic, and boreal) plant communities, and individual moss species often have low cover and/or frequency. Moss species with coverages of 2% to 4% can be common to dominant in boreal communities, although ribbed bog mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Nevada
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. 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 Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leptobryum Pyriforme
''Leptobryum pyriforme'' is a species of moss belonging to the family Bryaceae. It has a cosmopolitan distribution. ''Leptobryum pyriforme'' is known for its ability to utilize artificial light to grow in environments that are otherwise devoid of natural light, such as Crystal Cave in Wisconsin Wisconsin () is a state in the upper Midwestern United States.

NatureServe
NatureServe, Inc. is a non-profit organization based in Arlington County, Virginia, US, that provides proprietary wildlife conservation-related data, tools, and services to private and government clients, partner organizations, and the public. NatureServe reports being "headquartered in Arlington, Virginia, with regional offices in four U.S. locations and in Canada." In calendar year 2011 they reported having 86 employees, 6 volunteers, and 15 independent officers. History The Nature Conservancy reports that in 2000 it spun off its 85-center Natural Heritage Network "into a new independent organization, the Association for Biodiversity Information (later renamed NatureServe)." NatureServe reports that it was established in 1994 as the Association for Biodiversity Information. In 2001 the IRS approved a name change to NatureServe that was requested in 1999, while maintaining the organization's 501(c)(3) tax-exempt status granted in July 1995.

California Native Plant Society
The California Native Plant Society (CNPS) is a California environmental non-profit organization (501(c)3) that seeks to increase understanding of California's native flora and to preserve it for future generations. The mission of CNPS is to conserve California native plants and their natural habitats, and increase understanding, appreciation, and horticultural use of native plants throughout the entire state and California Floristic Province. History California Native Plant Society was founded in 1965 by professional botanists and grassroots activists who, after saving an important native plant garden in Berkeley's Tilden Regional Park, were inspired to create an ongoing organization with the mission to save and promote the native plants of California. Structure For 50 years, professional CNPS staff and volunteers have worked alongside scientists, government officials, and regional planners to protect habitats and species, and to advocate for well-informed environmental practic ...

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. The agency manages about 25% of federal lands and is the only major national land management agency not part of the U.S. Department of the Interior, which manages the National Park Service, the U.S. Fish and Wildlife Service, and the Bureau of Land Management. History The concept of national forests was born from Theodore Roosevelt's conservation group, Boone and Crockett Club, due to concerns regarding Yellowstone National Park beginning as early as 1875. In 1876, Congress formed the office of Special Agent in the Department of Agriculture to assess the quality and conditions of forests in the United States. ...

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 com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pinus Contorta
''Pinus contorta'', with the common names lodgepole pine and shore pine, and also known as twisted pine, and contorta pine, is a common tree in western North America. It is common near the ocean shore and in dry montane forests to the subalpine zone, subalpine, but is rare in lowland temperate rainforest, rain forests. Like all pines (member species of the genus ''Pinus''), it is an evergreen conifer. Description Depending on subspecies, ''Pinus contorta'' grows as an evergreen shrub or tree. The shrub form is krummholz and is approximately high. The thin and narrow-crowned tree can grow high and achieve up to in diameter at chest height. The ''murrayana'' subspecies is the tallest. The Crown (botany), crown is rounded and the top of the tree is flattened. In dense forests, the tree has a slim, conical crown. The formation of twin trees is common in some populations in British Columbia. The elastic branches stand upright or overhang and are difficult to break. The branches a ...
