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 from the extreme southeast of Alaska, through western British Columbia, Washington and Oregon, to the extreme northwest of California. It is also commonly referred to as the white fir, red fir, lovely fir, Amabilis fir, Cascades fir, or silver fir. It grows at altitudes of sea level to 1,500 metres (4,900 ft) in the north of the range, and 1,000–2,300 m (3,300–7,500 ft) in the south of the range, always in temperate rain forest with relatively high precipitation and cool, humid summers. Common associate trees are Douglas fir and in the extreme southern area of its range, California buckeye.

It is a large evergreen coniferous tree growing to 30–45 m (98–148 ft), exceptionally 72 m (236 ft) tall, and with a trunk diameter of up to 1.2 m (3 ft 11 in), exceptionally 2.3 m (7 ft 7 in). The bark on younger trees is light grey, thin and covered with resin blisters. On older trees, it darkens and develops scales and furrows. The leaves are needle-like, flattened, 2–4.5 cm (0.79–1.77 in) long and 2 mm (0.079 in) wide by 0.5 mm (0.02 in) thick, matte dark green above, and with two white bands of stomata below, and slightly notched at the tip. The leaf arrangement is spiral on the shoot, but with each leaf variably twisted at the base so they lie flat to either side of and above the shoot, with none below the shoot. The shoots are orange-red with dense velvety pubescence. The cones are 9–17 cm (3.5–6.7 in) long and 4–6 cm (1.6–2.4 in) broad, dark purple before maturity; the scale bracts are short, and hidden in the closed cone. The winged seeds are released when the cones disintegrate at maturity about 6–7 months after pollination.
Pacific silver fir is very closely related to Maries' fir A. mariesii from Japan, which is distinguished by its slightly shorter leaves—1.5–2.5 cm (0.59–0.98 in)—and smaller cones, which are 5–11 cm (2.0–4.3 in) long.
The wood is soft and not very strong; it is used for paper making, packing crates and other cheap construction work. The foliage has an attractive scent and is sometimes used for Christmas decoration, including Christmas trees.
It is also planted as an ornamental tree in large parks, though its requirement for cool, humid summers limits the areas where it grows well; successful growth away from its native range is restricted to areas like western Scotland and southern New Zealand.
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 (or conks) 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.
This species is found in the Pacific Northwest region of North America where it grows on large (at least 1 m diameter) specimens of noble fir (Abies procera), Pacific silver fir (Abies amabilis), or western hemlock (Tsuga heterophylla). Bridgeoporus nobilissimus causes a brown rot in its tree hosts. Genetic analysis shows that the fungus is more prevalent than fruit body distribution indicates.British Columbia Mainland Coastal Forests (WWF ecoregion)
British Columbia mainland coastal forests is a temperate coniferous forest ecoregion the Pacific coast of North America, as defined by the World Wildlife Fund (WWF) categorization system.Dodecatheon austrofrigidum
Dodecatheon austrofrigidum (syn. Primula austrofrigida) is a species of flowering plant in the primrose family known by the common names frigid shooting star and tundra shooting star. It is native to Washington and Oregon in the United States, where it grows in the coastal mountain ranges, including those on the Olympic Peninsula.This plant has a basal clump of leaves up to 30 centimeters long by 7 wide and have smooth to wavy or somewhat toothed edges. The inflorescence is borne on a flowering stalk up to 45 centimeters tall. It has one to seven flowers with magenta corolla lobes up to 2 centimeters long or more which are reflexed away from the flower center. The stamens are maroon or purple and forms a protruding tube.This plant grows on rocky slopes on river banks and other seasonally moist, rocky areas. It may grow with various mosses that form a substrate that it can root in. Associated plants include Alnus rubra, Filipendula occidentalis, Rubus parviflorus, Rubus spectabilis, Saxifraga occidentalis, Saxifraga nuttallii, Saxifraga mertensiana, and Mimulus guttatus, though it often grows on slopes with few other plants around. At higher elevations the plant occupies grassy turf. The soil is thin. The plant has also been found growing in substrates of decomposing wood. Associated species at higher elevations include Abies amabilis, Tsuga heterophylla, Cladothamnus sp., and Synthyris schizantha.This plant is known to occur at only about eight locations. Populations are small and scattered. Threats include increased flooding caused by grazing and logging upstream. The status of the rivers next to populations affects population size; the plant numbers may decrease during flood conditions and then increase the following year.Erythronium elegans
Erythronium elegans is a rare species of flowering plant in the lily family known by the common names Coast Range fawnlily and elegant fawnlily. It is endemic to Oregon in the United States, where it is known from about 12 occurrences in the northern Coast Range.This plant grows from a slender bulb 3 to 5 centimeters long. It produces two leaves up to 20 centimeters long which are green, sometimes with brownish or white mottling. The scape grows up to 30 centimeters tall and bears one to four flowers. The flower has six tepals, the inner three white and the outer three white tinged with pink. The tepals have yellow bands near the bases. They are 2 to 4 centimeters long. The protruding stamens are tipped with yellow anthers each 1 to 2 centimeters long. Blooming occurs in May and June.This plant is very restricted in distribution but it grows in a range of habitat conditions, with varying light and moisture levels. It can be found in open and deep forests, the edges of bogs, cliffs, and meadows. The local forests are dominated by Douglas-fir (Pseudotsuga menziesii) and other plants in the habitat may include Pacific silver fir (Abies amabilis), western redcedar (Thuja plicata), spruce (Picea sp.), false lily-of-the-valley (Maianthemum dilatatum), California glacier lily (Erythronium grandiflorum var. pallidum), strawberry (Fragaria sp.), snowberry (Gaultheria sp.), blueberry (Vaccinium sp.), and lupine (Lupinus spp.).In the wild this plant appears to be a poor competitor, persisting in areas with low soil nutrients where competition with other plants is low. However, it has been shown to grow well in cultivation.Eupithecia annulata

Firs (Abies) are a genus of 48–56 species of evergreen coniferous trees in the family Pinaceae. They are found through much of North and Central America, Europe, Asia, and North Africa, occurring in mountains over most of the range. Firs are most closely related to the genus Cedrus (cedar). Douglas firs are not true firs, being of the genus Pseudotsuga.
They are large trees, reaching heights of 10–80 m (33–262 ft) tall with trunk diameters of 0.5–4 m (1 ft 8 in–13 ft 1 in) when mature. Firs can be distinguished from other members of the pine family by the way in which their needle-like leaves are attached singly to the branches with a base resembling a suction cup, and by their cones, which, like those of true cedars (Cedrus), stand upright on the branches like candles and disintegrate at maturity.
Identification of the different species is based on the size and arrangement of the leaves, the size and shape of the cones, and whether the bract scales of the cones are long and exserted, or short and hidden inside the cone.Gabriola dyari
Gabriola dyari is a moth of the Geometridae family. It is found from the Alaskan panhandle and British Columbia to California. The habitat consists of coniferous forests.

They have a rusty brown to gray body with white dorsal patches and a light tan head with reddish-brown mottling. They reach a length of up to 20 mm. When at rest, the larva resembles a bird dropping. Larvae can be found from May to July. The species overwinters as an egg. Pupation takes place in a cocoon on a twig in August.List of flora of Washington (state)
