Pseudotsuga is a genus of evergreen coniferous trees in the family Pinaceae. Common names for species in the genus include Douglas fir, Douglas-fir, Douglas tree, Oregon pine and Bigcone spruce. Pseudotsuga menziesii is widespread in western North America and is an important source of timber. The number of species has long been debated, but two in western North America and two to four in eastern Asia are commonly acknowledged.
The Douglas fir is an evergreen conifer species in the pine family, Pinaceae. It is native to western North America and is also known as Douglas-fir, Douglas spruce, Oregon pine, and Columbian pine. There are three varieties: coast Douglas-fir, Rocky Mountain Douglas-fir and Mexican Douglas-fir.
Olympic National Park is a United States national park located in the State of Washington, on the Olympic Peninsula. The park has four regions: the Pacific coastline, alpine areas, the west-side temperate rainforest, and the forests of the drier east side. Within the park there are three distinct ecosystems, including subalpine forest and wildflower meadow, temperate forest, and the rugged Pacific coast.
The Olympic Mountains are a mountain range on the Olympic Peninsula of the Pacific Northwest of the United States. The mountains, part of the Pacific Coast Ranges, are not especially high – Mount Olympus is the highest summit at 7,980 ft (2,432 m); however, the eastern slopes rise precipitously out of Puget Sound from sea level, and the western slopes are separated from the Pacific Ocean by the low-lying 20 to 35 km wide Pacific Ocean coastal plain. These densely forested western slopes are the wettest place in the 48 contiguous states. Most of the mountains are protected within the bounds of Olympic National Park and adjoining segments of the Olympic National Forest.
Quercus garryana is an oak tree species of the Pacific Northwest, with a range stretching from southern California to southwestern British Columbia. It is commonly known as the Garry Oak, Oregon white oak or Oregon oak. It grows from sea level to an altitude of 690 feet in the northern part of its range, and from 980 to 5,900 ft in the south of the range in California. The eponymous Nicholas Garry was deputy governor of the Hudson's Bay Company.
Thuja plicata is a large evergreen coniferous tree in the family Cupressaceae, native to the Pacific Northwest of North America. Its common name is western redcedar in the U.S. or western red cedar in the UK, and it is also called pacific red cedar, giant arborvitae, western arborvitae, just cedar, giant cedar, or shinglewood. It is not a true cedar of the genus Cedrus. T. plicata is the largest species in the genus Thuja, growing up to 70 metres (230 ft) tall and 7 metres (23 ft) in diameter. It mostly grows in areas that experience a mild climate with plentiful rainfall, although it is sometimes present in drier areas on sites where water is available year-round, such as wet valley bottoms and mountain streamsides. The species is shade-tolerant and able to establish in forest understories and is thus considered a climax species. It is a very long-lived tree, with some specimens reaching ages of well over 1,000 years.
Pinus ponderosa, commonly known as the ponderosa pine, bull pine, blackjack pine, western yellow-pine, or filipinus pine is a very large pine tree species of variable habitat native to mountainous regions of western North America. It is the most widely distributed pine species in North America.
Prunus virginiana, commonly called bitter-berry, chokecherry, Virginia bird cherry, and western chokecherry, is a species of bird cherry native to North America.
Tsuga heterophylla, the western hemlock or western hemlock-spruce, is a species of hemlock native to the west coast of North America, with its northwestern limit on the Kenai Peninsula, Alaska, and its southeastern limit in northern Sonoma County, California. The Latin species name means 'variable leaves'.
The large yellow underwing is a moth, the type species for the family Noctuidae. It is an abundant species throughout the Palearctic realm, one of the most common and most familiar moths of the region. In some years the species is highly migratory with large numbers appearing suddenly in marginal parts of the range.
Salmo-Priest Wilderness is a 41,335 acre (167.28 km2) wilderness area located in the Selkirk Mountains in the northeast corner of Washington state, within the Colville National Forest and the Kaniksu National Forest.
Acronicta impressa, the impressive dagger moth or willow dagger moth, is a moth of the family Noctuidae. The species was first described by Francis Walker in 1856. It is found from western Canada to north-western Mexico.
Autographa sansoni, the Alberta beauty, is a moth of the family Noctuidae. The species was first described by F. H. Wolley Dod in 1910. It is found in the western mountains of North America, from Alaska south to Oregon, Idaho and Arizona. Occurring mainly in the Pacific Northwest, it thrives in mid-to-high elevation conifer forest habitat, as well as some areas of coastal rain forest in the Coast range. However, it is also found in a non-contiguous range in sub-alpine forest in the Rocky Mountains, ranging from Alberta in the north, to New Mexico in the south. The wingspan of an adult ranges between 34 and 36 mm. It is widespread, and a relatively common species.
Hydraecia obliqua is a moth in the family Noctuidae first described by Leon F. Harvey in 1876. It is found in western North America, east to the Sierra Nevada in California and the crest of the Cascade Range in Oregon and Washington. It occurs continuously on the coast north to south-western British Columbia, with a disjunct northern population at Terrace, British Columbia. The habitat consists of the riparian zone along creeks and rivers of coastal rainforests, as well as oak savanna, mixed hardwood forests and valley grasslands.
Pseudohemihyalea edwardsii, or Edwards' glassy-wing, is a moth in the family Erebidae. It was described by Alpheus Spring Packard in 1864. It is found in the United States from western Oregon and the Columbia Gorge in southern Washington south to California, in the south-west east to western New Mexico. The habitat consists of oak woodlands and mixed hardwood forests at low elevations.
Euthyatira is a genus of moths in the subfamily Thyatirinae. It was first described by Smith in 1891.
Euthyatira pudens, the dogwood thyatirid moth or peach-blossom moth, is a moth of the family Drepanidae. The species was first described by Achille Guenée in 1852. It is found in North America, where it ranges across southern Canada, south to the Gulf of Mexico. The habitat consists of moist forests and riparian zones along creeks at low to middle elevations.
Euthyatira semicircularis is a moth in the family Drepanidae. It is found in North America, where it has been recorded from British Columbia to California, east to Utah. The habitat consists of coastal rainforests and boreal forests.
Ponderosa pine forest is a plant association and plant community dominated by ponderosa pine and found in western North America. It is found from the British Columbia to Durango, Mexico. In the south and east, ponderosa pine forest is the climax forest, while in the more northern part of its range, it can transition to Douglas-fir or grand fir, or white fir forests. Understory species depends on location. Fire suppression has led to insect outbreaks in ponderosa pine forests.
Hovea lorata, is a species of flowering plant in the family Fabaceae and is endemic to eastern Australia. It is a shrub with lorate (strap-shaped) leaves, and mauve and greenish-yellow, pea-like flowers.
