Cascade Head
Cascade Head is a headland and UNESCO biosphere reserve and United States Forest Service Experimental Forest. It is situated southwest of Portland, Oregon on the Oregon Coast between Lincoln City and Neskowin. Cascade Head Preserve is a Nature Conservancy Selected Site. The Nature Conservancy In the early 1960s, volunteers organized an effort to protect Cascade Head from development. By 1966 they had raised funds and purchased the property, and then turned it over to The Nature Conservancy. Because of its ecological significance, Cascade Head Preserve and surrounding national forest and other lands won recognition in 1980 as a National Scenic Research Area and a United Nations Biosphere Reserve. Conservancy researchers are testing methods of maintaining and restoring grassland habitat for the Oregon silverspot butterfly, including prescribed fire. Conservancy ecologists also monitor the populations of rare plants throughout the year. In spring and summer, teams of volunt ...

Tillamook County, Oregon
Tillamook County is one of the 36 counties in the U.S. state of Oregon. As of the 2020 census, the population was 27,390. The county seat is Tillamook. The county is named for the Tillamook or Killamook people, a Native American tribe who were living in the area in the early 19th century at the time of European American settlement. The county is located within Northwest Oregon. The Tillamook were the southernmost branch of the Coast Salish. They were separated from their more northern kinsmen by tribes speaking the Chinookian languages. The name Tillamook is of Chinook origin (a trade pidgin, which had developed along the lower Columbia.) According to Frank Boas, "It illamookmeans the people of Nekelim. The latter name means the place of Elim, or in the Cathlamet dialect, the place of Kelim. The initial t of Tillamook is the plural article, the terminal ook the Chinook plural ending —uks." Since there was one village in the area of Nehalem bay; the area was referred t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Alder
''Alnus rubra'', the red alder, is a deciduous broadleaf tree native to western North America (Alaska, Yukon, British Columbia, Washington, Oregon, California, Idaho and Montana). Description Red alder is the largest species of alder in North America and one of the largest in the world, reaching heights of . The official tallest red alder (as of 1979) stands tall in Clatsop County, Oregon (US). The trunks range from in diameter. The bark is mottled, ashy-gray and smooth, often colonized by white lichen and moss. The leaves are ovate, long, with bluntly serrated edges and a distinct point at the end; the leaf margin is revolute, the very edge being curled under, a diagnostic character which distinguishes it from all other alders. The leaves turn yellow in the autumn before falling. The male flowers are dangling reddish catkins long in early spring. Female flowers occur in clusters of (3) 4–6 (8). Female catkins are erect during anthesis, but otherwise pendant. They ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viola Adunca
''Viola adunca'' is a species of violet known by the common names hookedspur violet, early blue violet, sand violet, and western dog violet. It is native to meadows and forests of western North America, Canada, and the northern contiguous United States. Description This is a hairy, compact plant growing from a small rhizome system. The leaves are spade- or heart-shaped, sometimes with broadly wavy margins. They are generally 0.5 to 4 centimeters long. The single-flowered inflorescence grows at the end of a very thin peduncle reaching about high. The nodding flower is a violet about long, with five purple petals. The lower three petals have white bases and purple veining. The two side petals are white-bearded near the throat. The upper two petals may have hooked spurs at their tips. It is a perennial blooming in late spring. There are several varieties of ''V. adunca''; a white-petaled form has been noted in Yosemite National Park. It has also been observed in Southern Ont ...

Sidalcea
''Sidalcea'' is a genus (approx. 25 species) of the botanical family Malvaceae. It contains several species of flowering plants known generally as checkerblooms or checkermallows, or prairie mallows in the United Kingdom. They can be annuals or perennials, some rhizomatous. They are native to West and Central North America. In mid- to late summer the clumps of toothed basal leaves produce erect flowering stems, with 5-petalled mallow-type flowers in terminal racemes, in shades of pink, white and purple. ''Sidalcea'' is generally diploid (2n = 20), but polyploidy (4n, 6n) also occurs. Annuality appears to have evolved multiple times (4+) within this genus, although an ancestral annual state with annual paraphyly is also possible. Further, evolution rates within annual ''Sidalcea'' lineages appear to be faster than those of perennial lineages, at least when examining nuclear ribosomal DNA (internal and external transcribed spacer regions). Selected species: (A = annual, P = ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lupinus Rivularis
''Lupinus rivularis'' is a species of lupine known by the common name riverbank lupine native to North America. It is also commonly known as river lupine, streambank lupine, and stream lupine.Darris, D.; Young-Mathews, A. Plant Fact Sheet for Riverbank Lupine (Lupinus rivularis); USDA NRCs Plant Materials Center: Corvallis, OR, USA, 2012. Distribution ''Lupinus rivularis'' is found in western North America, from southern British Columbia to northern California. Specifically, it is native to California, Oregon, Washington, and British Columbia. It mainly exists from coastal habitat in places such as both Olympic and Redwood National Parks, and at Point Reyes National Seashore. Its development in these regions is driven by its preference for sandy, well-drained, and low nitrogenous soils, along with precipitation levels between 20 and 100 inches. Additionally, this species observes optimal growth in environments with full sunlight. Riverbank lupine is able to well establish a popul ...

Goldenrod
Goldenrod is a common name for many species of flowering plants in the sunflower family, Asteraceae, commonly in reference to the genus '' Solidago''. Several genera, such as '' Euthamia'', were formerly included in a broader concept of the genus ''Solidago''. Some authors treat ''Oligoneuron'', the flat-topped goldenrods, as a separate genus than ''Solidago'', while others consider it a section: ''Solidago'' sect. ''Ptarmicoidei''. Goldenrods can be used as a sustainable method to enrich soil with nitrogen. With an increase of nitrogen levels, there can then be an increase of vegetative growth. Plants known as goldenrods include: *'' Bigelowia'' spp., rayless goldenrods, 2 species native to the Southeastern United States *''Cuniculotinus gramineus ''Cuniculotinus'' is a genus of flowering plants in the family Asteraceae.

Red Fescue
''Festuca rubra'' is a species of grass known by the common name red fescue or creeping red fescue. It is widespread across much of the Northern Hemisphere and can tolerate many habitats and climates. It is best adapted to well-drained soils in cool, temperate climates; it prefers shadier areas and is often planted for its shade tolerance. Wild animals browse it, but it has not been important for domestic forage due to low productivity and palatability. It is also an ornamental plant for gardens. Description ''Festuca rubra'' is perennial and has sub-species that have rhizomes and/or form bunchgrass tufts. It mainly exists in neutral and acidic soils. It can grow between 2 and 20 cm tall. Like all fescues, the leaves are narrow and needle like, making it less palatable to livestock. The swards that it forms are not as tufted as sheep's fescue (''Festuca ovina'') or wavy hair grass (''Deschampsia flexuosa''). The tufted nature is what gives the grass its springy character ...

Salt Marsh
A salt marsh or saltmarsh, also known as a coastal salt marsh or a tidal marsh, is a coastal ecosystem in the upper coastal intertidal zone between land and open saltwater or brackish water that is regularly flooded by the tides. It is dominated by dense stands of salt-tolerant plants such as herbs, grasses, or low shrubs. These plants are terrestrial in origin and are essential to the stability of the salt marsh in trapping and binding sediments. Salt marshes play a large role in the aquatic food web and the delivery of nutrients to coastal waters. They also support terrestrial animals and provide coastal protection. Salt marshes have historically been endangered by poorly implemented coastal management practices, with land reclaimed for human uses or polluted by upstream agriculture or other industrial coastal uses. Additionally, sea level rise caused by climate change is endangering other marshes, through erosion and submersion of otherwise tidal marshes. However, r ...
