    Abies ziyuanensis, first described in by Fu Li-Kuo and Mo Sin-Li, is commonly known as Zhiyuan fir, or 资源冷杉 (Zhiyuan lengshan) in the Chinese language.. n fir is an evergreen coniferous species of tree that will grow to mature heights of feet (30 m) tall with a 36 inch (90 cm) wide trunk at breast height, with a straight round trunk and long, horizontally. Fir cones on the other hand remain upright or erect (figures ). Cones consist of scales attached to a central stalk. At maturity, the scales of pine and spruce remain attached to the central stalk and the entire cone frequently falls to the ground intact after most of the winged seeds are dispersed from between the scales.

    Abies delavayi, as described in by Phillippe Édouard Léon van Tieghem and later by Adrien René Franchet, is commonly known as Delavay fir; or 苍山冷杉 (cang shan leng shan) in the Chinese language. It was named for its discoverer, Father I.M. Delavay who collected it at 10, to 12, feet (3, - 4, m) elevation on Cangshan near Dali in Yunnan in April of   The cones of fir trees (Abies sp.) vary widely among cones of fir trees can range from very small ( inches-long) on Frasier fir (A. fraseri) to large (10 inches-long) on noble fir (A. procera).White fir (A. concolor) produces cylindrical female cones, up to inches-long, on branches with soft fir is recommended for planting in Missouri, and is often sold at cut.

    Abies concolor (Gord.& Glend.) Lindl. ex Hildebr. White Fir. Pinaceae -- Pine family. Robert J. Laacke. Long considered undesirable for timber, white fir (Abies concolor) is finally being recognized as a highly productive, valuable tree fir reaches its best development and maximum size in the central Sierra Nevada of California, where the record specimen is m ( ft) tall. purplish-red, but often unnoticed Fruits. upright cones are about 5" long, pale green with a deep purplish cast, changing to brown at maturity Twigs. off-white smooth stems change to light gray with age all stems lie in the same plane of the main branch, giving the tree a distinctly layered branching effect (similar to some Blue Spruce).

Seed maturity in white fir and red fir. Berkeley, Calif.: Pacific Southwest Forest and Range Experiment Station, Forest Service, U.S. Dept. of Agriculture, (OCoLC) Data suggest that red fir cones should be collected as close to beginning of seed fall as possible.

White fir cones should be collected within 3½ weeks of seed fall. White fir cones collected 4 weeks before seed fall can be artificially ripened, however. Seed maturity in white fir and red fir. USDA Forest Service, Research Paper PSW Pacific Southwest Forest and Range Experiment Station, Berkeley, CA.

12 p. Oliver, William W. Unpublished data. Pacific Southwest Forest and Range Experiment Station. as maturity indices of white and red fir seeds, and reports a limited test of artificial ripening of white fir cones.

METHODS Seeds tested in came from six white and eight red fir trees in a mixed stand at 6, feet elevation on the Latour State Forest. The Forest lies on the west slope of the Cascade Range, 37 miles eastCited by: 2.

Abstract. This chapter summarizes current technology concerning cone collection and seed processing, testing, storage, and stratification for the six major conifer species—Douglas-fir, ponderosa pine, lodgepole pine, noble fir, white fir, and western hemlock—produced Cited by: The winged seeds are released when the cones disintegrate at maturity about 6 months after pollination The White Fir species offers a perfect combination of strength, versatility and beauty.

White Fir is a preferred construction species because of its nail-holding ability, lightness in weight, and resistance to split, twist, and pitch. Fir - White Fir, Concolor Fir - Abies concolor Seeds.

White fir (Abies concolor) is a fir native to the mountains of western North America, occurring at elevations ofm (2, ft). It is a medium to large evergreen coniferous tree growing to 25–60 m ( ft) tall and with a trunk diameter of up to 2 m ( ft).

It is popular as an ornamental landscaping tree and as a. The best, most reliable producers are mature, healthy dominants. Immature fir can produce heavy seed crops, but production is more erratic than that of mature trees (18). California red fir seeds aver/kg (6,/lb). Shasta red fir seeds tend to be smaller and aver/kg (7,/lb) (36).

White fir in shallow soils can be damaged by strong winds. The chances of windthrow are increased when neighboring trees are removed. Seeds and Plant Production. White fir is produced by seeds. Seeds are ready for collection when the cone easily breaks apart.

Franklin Noble fir (Abies procera), also known as red fir and white fir, is an impressive true fir limited to the Cascade • Range and Coast Ranges of the Pacific Northwest.

At maturity, it typically has a clean, columnar bole and short, rounded crown. Noble fir attains the largest dimensions of any of. Seven species of true fir are native to western North America, and Oregon has six--more than any other state: grand fir, Pacific silver fir, noble fir, California red fir, subalpine fir, and white fir.

All true firs have the following characteristics. White Fir (Abies concolor - Iowiana) The White Fir tree is considered the best Fir tree for the Midwest and East.

The White Fir tree produces beautiful foliage. Grows to heights of 30 to 50 feet. Soil Type: Prefers deep, rich, moist, well-drained gravelly or sandy-loam soils; dislikes heavy clay, fun sun, but will tolerate light shade.

Zones: 4 to 7. White fir may be regenerated by natural seeding, direct seeded, or planted. Cones begin to disintegrate and shed seeds in late September or early October, and there is a good seed crop about every 2 to 5 years.

The seed germinates in the spring but usually less than 50 percent of the seed germinate. White fir. Seed maturity in white fir and red fir. USDA For. Serv. Res. Note PSW– Maturation of sugar maple seed. USDA Forest Service Research Paper NE The IUCN Plant Red Data Book.

The Int. The white fir is a moderately prolific seeder and the red fir is a very prolific one. Heavy seed years occur at intervals of from two to three years, and some seed is borne every year.

The cones of the two trees afford another means of distinction between them, those of the white fir being from 3 to 5 inches long, while those of the red fir are from 6 to 8 inches long. Publisher: Berkeley, Calif.: Pacific Southwest Forest and Range Experiment Station, Forest Service, U.S.

Dept. of Agriculture. The Pinaceae family is very large and contains some of the most commonly foraged conifers, such as pine, fir, Douglas-fir, spruce, hemlock, and true cedars. Pine Tree Identification Pine trees (Pinus spp.) have needles that are bundled in clusters ofwith being most common, depending on the species.

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 is also commonly referred to as the white fir, red fir, lovely fir, Amabilis fir.

Abies concolor, the white fir, is a coniferous tree in the pine family tree is native to the mountains of western North America from the southern Cascade range in Oregon, south throughout California and into the Sierra de San Pedro Mártir in northern Baja California; east through parts of southern Idaho, to Wyoming; and south throughout the Colorado Plateau and southern Rocky.

Native to the western mountain states, the white fir (Abies concolor) also known as concolor fir, has been planted in Iowa for ornamental and windbreak use.

Where native, it is a large tree to feet tall. In Iowa, it reaches a height of 50 to 80 feet. It is a hardy tree and grows on a wide range of soils.

In the North American lumberjack circles, the grand fir is also known as the ‘hem fir’, which is an umbrella term coined to refer to the noble fir, California red fir, Pacific silver fir, western hemlock fir and the white fir (Abies concolor).

The scent of the grand fir is citrus like, thus adding to its popularity as a Christmas tree.Douglas-fir is classified as an intermediate shade intolerant after its first few years. It is, however, more tolerant than most associates including ponderosa pine, Jeffrey pine, sugar pine, western white pine, lodgepole pine, incense-cedar, noble fir, and red alder, but less than white fir.
