North Creek Forest
The North Creek Forest is located in Bothell, Washington and surrounds a section of the North Creek and encompasses 64 acres of mature second growth mixed coniferous/hardwood forest with 7 streams and 9 wetlands. The forest forms a one mile long and up to 1/3- mile wide habitat corridor extending from Canyon Park Junior High School in the north almost to the North Creek wetlands near the University of Washington Bothell Campus, and eventually links to the Sammamish River in the south. The North Creek Forest is one of the last remaining mature coniferous forests in the Bothell area. The forest here filters and cools water in streams, wetlands and countless small springs and seeps, along an entire mile of watershed. The cooling of this water is crucial for 5 species of anadromous fish that spawn in North Creek including chum, coho, sockeye, chinook and steelhead. Many other ecosystem services are provided by this forest including carbon sequestration, reduction of surface run ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bothell, Washington
Bothell () is a city in King and Snohomish counties in the U.S. state of Washington. It is part of the Seattle metropolitan area, situated near the northeast end of Lake Washington. As of the 2020 census, it had a population of 48,161 residents. History The Sammamish River valley from Lake Washington to Issaquah Creek was historically inhabited by the indigenous Sammamish people (also known as the "s-tah-PAHBSH", or "willow people"), a Coast Salish group with an estimated population of 80 to 200 by 1850. Among them were the "ssts'p-abc" ("meander dwellers"), who settled near the river's mouth at two villages—the larger of which was "tlah-WAH-dees" between modern-day Kenmore and Bothell. The Sammamish were removed from their lands in 1856 following the Puget Sound War and moved to the Port Madison and Tulalip indian reservations. The first American claims to the lower Sammamish River valley, then mostly a marshland, were filed in 1870 by Columbus S. Greenleaf and George R. ...

Rhamnus Purshiana
''Frangula purshiana'' (cascara, cascara buckthorn, cascara sagrada, bearberry, and in the Chinook Jargon, chittem stick and chitticum stick; syn. ''Rhamnus purshiana'') is a species of plant in the family Rhamnaceae. It is native to western North America from southern British Columbia south to central California, and eastward to northwestern Montana. The dried bark of cascara was used as a laxative in folk medicine by the indigenous peoples of the Pacific Northwest, and later worldwide in conventional medicines until 2002. Description Cascara is a large shrub or small tree tall, with a trunk 20–50 centimetres (8–20 in) in diameter. The buds have no scales, unique for the northwest region. The thin bark is brownish to silver-gray with light splotching (often, in part, from lichens); the inner bark is smooth and yellowish (turning dark brown with age and/or exposure to sunlight). Cascara bark has an intensely bitter flavor that will remain in the mouth for hou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...

Pacific Tree Frog
The Pacific tree frog (''Pseudacris regilla''), also known as the Pacific chorus frog, has a range spanning the Pacific Northwest, from Northern California, Oregon, and Washington to British Columbia in Canada and extreme southern Alaska. They live from sea level to more than 10,000 feet in many types of habitats, reproducing in aquatic settings. They occur in shades of greens or browns and can change colors over periods of hours and weeks. Taxonomy The taxonomy of this frog has a very confusing history. First, the frog was moved from the genus ''Hyla'' to the genus ''Pseudacris'' in 1986, and ''Hyliola'' in 2016 (an elevation of the subgenus which has not been widely accepted). In 2006, Recuero ''et al.'' split the frog into three species based on DNA evidence. Recuero ''et al.'' used incorrect names for two of the three populations, but subsequent authors established that the correct name (i.e., the oldest available name) for the northern component is ''Pseudacris regilla'', ...

Pileated Woodpecker
The pileated woodpecker (''Dryocopus pileatus'') is a large, mostly black woodpecker native to North America. An insectivore, it inhabits deciduous forests in eastern North America, the Great Lakes, the boreal forests of Canada, and parts of the Pacific Coast. It is the largest confirmed extant woodpecker species in North America, with the possible exception of the ivory-billed woodpecker, which the U.S. Fish and Wildlife Service has proposed be reclassified as extinct. It is also the third largest species of woodpecker in the world, after the great slaty woodpecker and the black woodpecker. "Pileated" refers to the bird's prominent red crest, from the Latin meaning "capped". Taxonomy The English naturalist Mark Catesby described and illustrated the pileated woodpecker in his book ''The Natural History of Carolina, Florida and the Bahama Islands'' which was published between 1729 and 1732. Catesby used the English name "The larger red-crested Wood-pecker" and the Latin ''Picus n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Merlin (bird)
The merlin (''Falco columbarius'') is a small species of falcon from the Northern Hemisphere, with numerous subspecies throughout North America and Eurasia. A bird of prey once known colloquially as a pigeon hawk in North America, the merlin breeds in the northern Holarctic; some migrate to subtropical and northern tropical regions in winter. Males typically have wingspans of , with females being slightly larger. They are swift fliers and skilled hunters who specialize in preying on small birds in the size range of sparrows to quail. The merlin has for centuries been well regarded as a falconry bird. In recent decades merlin populations in North America have been significantly increasing, with some merlins becoming so well adapted to city life that they forgo migration. Nomenclature The merlin was described and illustrated by the English naturalist Mark Catesby (as the "pigeon hawk") in his ''Natural history of Carolina, Florida and the Bahama Islands'' published in 1729–17 ...

Cooper's Hawk
Cooper's hawk (''Accipiter cooperii'') is a medium-sized hawk native to the North American continent and found from southern Canada to Mexico. This species is a member of the genus ''Accipiter'', sometimes referred to as true hawks, which are famously agile, relatively small hawks common to wooded habitats around the world and also the most diverse of all diurnal raptor genera. As in many birds of prey, the male is smaller than the female.Snyder, N. F., & Wiley, J. W. (1976). ''Sexual size dimorphism in hawks and owls of North America (No. 20)''. American Ornithologists' Union. The birds found east of the Mississippi River tend to be larger on average than the birds found to the west.Pearlstine, E. V., & Thompson, D. B. (2004). ''Geographic variation in morphology of four species of migratory raptors''. Journal of Raptor Research, 38(4), 334–342. It is easily confused with the smaller but similar sharp-shinned hawk. (''A. striatus'') The species was named in 1828 by Charles Lu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Horned Owl
The great horned owl (''Bubo virginianus''), also known as the tiger owl (originally derived from early naturalists' description as the "winged tiger" or "tiger of the air"), or the hoot owl, is a large owl native to the Americas. It is an extremely adaptable bird with a vast range and is the most widely distributed true owl in the Americas. Its primary diet is rabbits and hares, rats and mice, and voles, although it freely hunts any animal it can overtake, including rodents and other small mammals, larger mid-sized mammals, birds, reptiles, amphibians, and invertebrates. In ornithological study, the great horned owl is often compared to the Eurasian eagle-owl (''Bubo bubo''), a closely related species, which despite the latter's notably larger size, occupies the same ecological niche in Eurasia, and the red-tailed hawk (''Buteo jamaicensis''), with which it often shares similar habitat, prey, and nesting habits by day, thus is something of a diurnal ecological equivalent.

Western Screech Owl
The western screech owl (''Megascops kennicottii'') is a small owl native to North and Central America, closely related to the eastern screech owl. The scientific name commemorates the American naturalist Robert Kennicott. Description Length averages , wingspan , and weight . Weight ranges from .''CRC Handbook of Avian Body Masses'' by John B. Dunning Jr. (Editor). CRC Press (1992), . Females are larger than males and northern populations are notably larger than southern populations. Adults are larger than whiskered screech owls, with larger feet and a more streaked plumage pattern. There are several morphs: brown Pacific, grey Pacific, Great Plains, Mojave, and Mexican. All have either brown or dark gray plumage with streaking on the underparts. There is no red morph. This brown and gray streaky coloring allows the owl to camouflage with trees and hide from predators. They have a round head with ear tufts, yellow eyes, and a yellowish bill. Their appearance is quite similar t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barred Owl
The barred owl (''Strix varia''), also known as the northern barred owl, striped owl or, more informally, hoot owl, is a North American large species of owl. A member of the true owl family, Strigidae, they belong to the genus '' Strix'', which is also the origin of the family's name under Linnaean taxonomy.Sclater, P. L. (1879). ''Remarks on the Nomenclature of the British Owls, and on the Arrangement of the Order Striges''. Ibis, 21(3), 346-352. Barred owls are largely native to eastern North America, but have expanded their range to the west coast of North America where they are considered invasive.Evers, L. (2014).

Mountain Beaver
The mountain beaver (''Aplodontia rufa'')Other names include mountain boomer, ground bear, giant mole, gehalis, lesser sasquatch, sewellel, suwellel, showhurll, showtl, and showte, as well as a number of Chinookan and other Native American terms; "mountain boomer" is a misnomer, and the animal does not make the characteristic tail slapping sound of the true beaver species. See Carraway and Verts, 1993. Lewis and Clark originally called the animal "sewellel", a misunderstanding of the Chinook word "she-wal-lal", the name for garments made from the skin of the creature. See Borrecco and Anderson, 1980. is a North American rodent. It is the only living member of its genus, ''Aplodontia'', and family, Aplodontiidae. It should not be confused with true North American and Eurasian beavers, to which it is not closely related, being more closely related to squirrels. There are 7 subspecies of mountain beavers, 6 of which are found in California and 3 of which are endemic to the state. S ...

Douglas Squirrel
The Douglas squirrel (''Tamiasciurus douglasii'') is a pine squirrel found in the Pacific Northwest of North America, including the northwestern coastal states of the United States as well as the southwestern coast of British Columbia in Canada, with an isolated subspecies in northern Baja California. It is sometimes known as the chickaree or pine squirrel, although these names are also used for the American red squirrel. Variant spellings of the common name are Douglas' squirrel and Douglas's squirrel. The Native Americans of Kings River called it the "Pillillooeet", in imitation of its characteristic alarm call. Description John Muir described the Douglas squirrel, ''Tamiasciurus douglasii'', as "by far the most interesting and influential of the California Sciuridæ". Adults are about 33 cm in length (including its tail, which is about 13 cm long), and weigh between 150 and 300 grams. Their appearance varies according to the season. In the summer, they are ...
