Tsuga is a genus of conifers in the subfamily Abietoideae of Pinaceae, the pine family. The English-language common name "hemlock" arose from a perceived similarity in the smell of its crushed foliage to that of the unrelated plant hemlock. Unlike the latter, Tsuga species are not poisonous.
Alnus rubra, the red alder, is a deciduous broadleaf tree native to western North America.
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 m (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.
Abies grandis is a fir native to northwestern North America, occurring at altitudes of sea level to 1,700 metres (5,600 ft). It is a major constituent of the Grand Fir/Douglas Fir Ecoregion of the Cascade Range.
Abies concolor, the white fir, concolor fir, or Colorado fir, is a coniferous tree in the pine family Pinaceae. This tree is native to the mountains of western North America, including the Sierra Nevada and southern Rocky Mountains, and into the isolated mountain ranges of southern Arizona, New Mexico, and Northern Mexico. It naturally occurs at elevations between 900 and 3,400 metres.
Acer macrophyllum, the bigleaf maple or Oregon maple, is a large deciduous tree in the genus Acer. It is native to western North America. In addition to uses by animals, it is of some culinary and woodworking interest.
Tsuga canadensis, also known as eastern hemlock, eastern hemlock-spruce, or Canadian hemlock, and in the French-speaking regions of Canada as pruche du Canada, is a coniferous tree native to eastern North America. It is the state tree of Pennsylvania. Eastern hemlocks are widespread throughout much of the Great Lakes region, the Appalachian Mountains, the Northeastern United States, and Maritime Canada. They have been introduced in the United Kingdom and mainland Europe, where they are used as ornamental trees.
Tsuga mertensiana, known as mountain hemlock, is a species of hemlock native to the west coast of North America, found between Southcentral Alaska and south-central California.
Acer circinatum, or vine maple, is a species of maple native to northwestern North America. Vine maple typically grows as a low-elevation coastal tree in temperate areas of high precipitation such as the west coast of Oregon and northern California, as well as the temperate rainforests of Washington and British Columbia. Vine maples play an important role in conserving the biodiversity of lowland ecosystems by enriching upper soil layers and providing habitat for other organisms.
Tsuga caroliniana, the Carolina hemlock, is a species of hemlock endemic to the United States. As of 2023, it is under review for listing under the Endangered Species Act of 1973.
Abies amabilis, commonly known as the Pacific silver fir, is a fir native to the Pacific Northwest of North America, occurring in the Pacific Coast Ranges and the Cascade Range. It is also commonly referred to in English as the white fir, red fir, lovely fir, amabilis fir, Cascades fir, or silver fir. The species name is Latin for 'lovely'.
Management of Pacific Northwest riparian forests is necessary because many of these forests have been dramatically changed from their original makeup. The primary interest in riparian forest and aquatic ecosystems under the Northwest Forest Plan (NWFP) is the need to restore stream habitat for fish populations, particularly anadromous salmonids. Some of these forests have been grazed by cattle or other livestock. The heavy hooves of these animals compact the soil. This compaction does not allow the water to be absorbed into the ground, so the water runs off into the stream carrying topsoil along the way.
Tsuga chinensis, commonly referred to as the Taiwan or Chinese hemlock, is a coniferous tree species native to China, Taiwan, and Vietnam. The tree is quite variable and has many recognised varieties, though some are also maintained to be separate species by certain authorities. The tree was recently discovered in the mountains of northern Vietnam, making that the southernmost extension of its range.
Craterellus tubaeformis is an edible fungus, also known as the winter chanterelle, yellowfoot, winter mushroom, or funnel chanterelle. It was reclassified from Cantharellus, which has been supported by molecular phylogenetics.
Craterellus lutescens, formerly sometimes called Cantharellus lutescens or Cantharellus xanthopus or Cantharellus aurora, commonly known as Yellow Foot, camagroc in Catalan, craterelle jaune in French, is a species of mushroom. It is closely related to Craterellus tubaeformis. Its hymenium is usually orange or white, whereas the hymenium of C. tubaeformis is grey. C. lutescens is also usually found in wetlands.
Bridgeoporus is a fungal genus in the family Polyporaceae. A monotypic genus, it contains the single polypore species Bridgeoporus nobilissimus, first described to science in 1949. Commonly known both as the noble polypore and the fuzzy Sandozi, this fungus produces large fruit bodies that have been found to weigh up to 130 kilograms (290 lb). The upper surface of the fruit body has a fuzzy or fibrous texture that often supports the growth of algae, bryophytes, or vascular plants.
Rhododendron menziesii, also classified as Menziesia ferruginea, is a species of flowering plant in the heath family Ericaceae, known by several common names, including rusty menziesia, false huckleberry, fool's huckleberry and mock azalea.
Pseudotsuga menziesii var. menziesii, commonly known as Coast Douglas-fir, Pacific Douglas-fir, Oregon pine, or Douglas spruce, is an evergreen conifer native to western North America from west-central British Columbia, Canada southward to central California, United States. In Oregon and Washington its range is continuous from the Cascades crest west to the Pacific Coast Ranges and Pacific Ocean. In California, it is found in the Klamath and California Coast Ranges as far south as the Santa Lucia Mountains with a small stand as far south as the Purisima Hills, Santa Barbara County. In the Sierra Nevada it ranges as far south as the Yosemite region. It occurs from near sea level along the coast to 1,800 metres (5,900 ft) in the California Mountains. Further inland, coast Douglas-fir is replaced by Rocky Mountain or interior Douglas-fir. Interior Douglas-fir intergrades with coast Douglas-fir in the Cascades of northern Washington and southern British Columbia.
Lepraria torii is a species of corticolous and lignicolous, leprose lichen in the family Stereocaulaceae. It is found in northwestern North America.
Hypogymnia canadensis is a species of corticolous (bark-dwelling), foliose lichen in the family Parmeliaceae. Found in western North America, it was formally described as a new species in 2007. Although Hypogymnia canadensi shares its habitat with several related species, it can be reliably identified through a combination of its morphological traits—such as narrower lobe width and smoother upper surface—and its unique chemical composition.
