Union Bay Natural Area
The Union Bay Natural Area (UBNA) in Seattle, Washington, also known as Union Bay Marsh, is the restored remainder of the filled former Union Bay and Union Bay Marsh. It is located at the east end of the main University of Washington campus, south of NE 45th Street and west of Laurelhurst. Ravenna Creek is connected to University Slough (Drainage Canal), thence to Union Bay, and Lake Washington. Drainage Canal is one of three or four areas of open water connected with Lake Washington around Union Bay Marsh. The canal extends from NE 45th Street, between the driving range and IMA Sports Field 1, south to the bay, ending southeast of the Husky Ballpark baseball grandstand (northeast of the IMA Building). The Drainage Canal that carries Ravenna Creek past UBNA to Union Bay is locally sometimes called University Slough. The little grasslands, modest ponds, and lake shoreline of the UBNA is a sanctuary for birds (including double-crested cormorants, great blue herons, and ea ...

Montlake Cut
The Montlake Cut is the easternmost section of the Lake Washington Ship Canal, which passes through the city of Seattle, linking Lake Washington to Puget Sound. It opened in 1916 after 56 years of conversation and construction to create the manmade canal. The path along the cut was designated a National Recreation Trail as Montlake Cut National Waterside in 1971. The cut provides a connection between Union Bay, part of Lake Washington, to the east and Portage Bay, an arm of Lake Union, to the west. It is spanned by the Montlake Bridge, a bascule drawbridge carrying Montlake Boulevard ( State Route 513). Most of the land on the north shore of the cut is occupied by the University of Washington, its medical school to the west and its stadium parking lot to the east; residences and a recreational trail occupy the south bank, which is part of the Montlake neighborhood. Before the creation of the Montlake Cut, the land was regularly used by the Duwamish tribe and the holds i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Convolvulus Arvensis
''Convolvulus arvensis'', or field bindweed, is a species of bindweed in the Convolvulaceae native to Europe and Asia. It is a rhizomatous and climbing or creeping herbaceous perennial plant with stems growing to in length. It is usually found at ground level with small white and pink flowers. Other common names, mostly obsolete, include lesser bindweed, European bindweed, withy wind (in basket willow crops), perennial morning glory, small-flowered morning glory, creeping jenny, and possession vine. Taxonomy Field bindweed was first described in 1753 by Carl Linnaeus in the ''Species Plantarum''. In the following centuries, many subspecies, varieties, and synonymous taxa were discovered and described as purportedly new species in places including China, Russia, Egypt, and Morocco. New species and forms were described as far as Chile, Mexico, and the state of California when botanists encountered the plant there, although it is not native to these areas. In the ninth volume ...

Rubus Armeniacus
''Rubus armeniacus'', the Himalayan blackberry or Armenian blackberry, is a species of ''Rubus'' in the blackberry group ''Rubus'' subgenus ''Rubus'' series ''Discolores'' (P.J. Müll.) Focke. It is native to Armenia and northern Iran, and widely invasive elsewhere. Both its scientific name and origin have been the subject of much confusion. In some areas, the plant is cultivated for its berries, but in many areas it is considered a noxious weed and an invasive species. Description ''Rubus armeniacus'' is a perennial plant that bears biennial stems ("canes") from the perennial root system. In its first year a new stem grows vigorously to its full length of 4–10 m, trailing along the ground or arching up to 4 m high. The stem is stout, up to diameter at the base, and green; it is polygonal (usually hexagonal) in cross-section, with fearsome thorns up to 1.5 cm long forming along the ribs. The canes can turn more red/purple if they are exposed to bright sunlight. This is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daylighting (streams)
Daylighting is the opening up and restoration of a previously buried watercourse, one which had at some point been diverted below ground. Typically, the rationale behind returning the riparian environment of a stream, wash, or river to a more natural above-ground state is to reduce runoff, create habitat for species in need of it, or improve an area's aesthetics. In the United Kingdom, the practice is also known as deculverting. In addition to its use in urban design and urban planning, planning the term also refers to the public process of advancing such projects. According to the Planning and Development Department of the City of Berkeley, "A general consensus has developed that protecting and restoring natural creeks' functions is achievable over time in an urban environment while recognizing the importance of property rights."

Stream
A stream is a continuous body of water, body of surface water Current (stream), flowing within the stream bed, bed and bank (geography), banks of a channel (geography), channel. Depending on its location or certain characteristics, a stream may be referred to by a variety of local or regional names. Long, large streams are usually called rivers, while smaller, less voluminous and more intermittent river, intermittent streams are known, amongst others, as brook, creek, rivulet, rill, run, tributary, feeder, freshet, narrow river, and streamlet. The flow of a stream is controlled by three inputs – surface runoff (from precipitation or meltwater), daylighting (streams), daylighted subterranean river, subterranean water, and surfaced groundwater (Spring (hydrology), spring water). The surface and subterranean water are highly variable between periods of rainfall. Groundwater, on the other hand, has a relatively constant input and is controlled more by long-term patterns of pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seattle, Lake Shore And Eastern Railway
The Seattle, Lake Shore and Eastern Railway (SLS&E) was a railroad founded in Seattle, Washington, on April 28, 1885, with three tiers of purposes: Build and run the initial line to the town of Ballard, Seattle, Ballard, bring immediate results and returns to investors; exploit resources east in the valleys, foothills, Cascade Range, and Eastern Washington in 19th-century style, attracting more venture capital; and boost a link to a Transcontinental railroad#United States, transcontinental railroad for Seattle, the ultimate prize for incorporation. The historical accomplishment of the line was Seattle to Sumas at the border, with British Columbia, Canada, connecting with the Canadian Pacific Railway, Canadian Pacific transcontinental at the border at Huntingdon, Abbotsford, Huntingdon, British Columbia, now part of the Abbotsford, British Columbia, City of Abbotsford.

Yesler Creek
Yesler Creek is a stream that originates in the Bryant and Wedgwood neighborhoods of Seattle, Washington, and flows southward to empty into Union Bay of Lake Washington. Portions are daylighted, such as those flowing between 39th and 40th Avenue NE and through Burke Gilman Park. The stream also continues underground underneath Seattle Children's Hospital. Restoration Members of the Green Seattle Partnership and the University of Washington The University of Washington (UW and informally U-Dub or U Dub) is a public research university in Seattle, Washington, United States.

Ravenna Creek
Ravenna Creek is a stream in the Ravenna and Roosevelt neighborhoods of Seattle, Washington, whose present daylighted length of nearly is entirely within the Ravenna & Cowen Parks. Ravenna Creek used to drain Green Lake into Lake Washington's Union Bay, but urban development and the lowering of the two lakes in 1911 and 1916 resulted in the disappearance of the creekbed between Green Lake and Cowen Park and between Ravenna Park and Union Bay. Ravenna Creek's current source is a wetland in the northwest corner of Cowen Park, at NE 62nd Street and Brooklyn Avenue NE. It is also fed by springs throughout Ravenna Park, and is joined there by a second branch which begins near the intersection of NE 65th Street and 23rd Avenue NE. Until 2006, the creek ended at a sewer grate where the park's trail system opened into a soccer field. A daylighting project completed in May 2006 disconnected the creek from the sewer system and extended its bed towards the southeast corner of Ra ...

Tachycineta Bicolor 3285
''Tachycineta'' is a genus of birds in the swallow family Hirundinidae. There are nine described species all restricted to the Americas. These are slender swallows with forked tails. Most species have a metallic green back, green or blue head, and metallic blue or unglossed brown wings. All have pure white underparts, and four species have a white rump. Most ''Tachycineta'' swallows are at least partially bird migration, migratory, with only Golden swallow (bird), golden and mangrove swallow being essentially resident. All the species use natural or disused cavities for nest sites. Taxonomy The genus ''Tachycineta'' was introduced by the German ornithologists Jean Cabanisin 1850 with the violet-green swallow (''Tachycineta thalassina'') as the type species. The genus name is from Ancient Greek ''takhukinētos'' meaning "moving quickly". The genus contains nine species, divided into two sub-clades that are associated with geography: a North American/Caribbean clade and a Sou ...

Soil
Soil, also commonly referred to as earth, is a mixture of organic matter, minerals, gases, water, and organisms that together support the life of plants and soil organisms. Some scientific definitions distinguish dirt from ''soil'' by restricting the former term specifically to displaced soil. Soil consists of a solid collection of minerals and organic matter (the soil matrix), as well as a porous phase that holds gases (the soil atmosphere) and water (the soil solution). Accordingly, soil is a three- state system of solids, liquids, and gases. Soil is a product of several factors: the influence of climate, relief (elevation, orientation, and slope of terrain), organisms, and the soil's parent materials (original minerals) interacting over time. It continually undergoes development by way of numerous physical, chemical and biological processes, which include weathering with associated erosion. Given its complexity and strong internal connectedness, soil ecologists ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
