Firs are evergreen coniferous trees belonging to the genus Abies (Latin: [ˈabieːs]) in the family Pinaceae. There are approximately 48–65 [3][4] extant species, found on mountains throughout much of North and Central America, Eurasia, and North Africa. The genus is most closely related to Keteleeria, a small genus confined to eastern Asia. [5]

2025年2月19日 · Fir, genus of more than 40 species of evergreen trees of the conifer family Pinaceae. The plants are native to North and Central America, Europe, Asia, and northern Africa. Several species are useful as a source of timber, and a number are cultivated as ornamentals.

Douglas-fir is one of the world's best timber-producing species and yields more timber than any other species in North America, making the forestlands of western Oregon, Washington, and British Columbia the most productive on the continent. In 2011, Douglas-fir represented 34.2% of US lumber exports, to a total of 1.053 billion board-feet.

Fir is any of the species of conifers belonging to the genus Abies included in the Pinaceae (or pine) family. These large trees, although closely related to cedars, can be distinguished from other conifers by their soft cones that perch upright like candles.

2022年3月24日 · Fir trees are woody plants that belong to the genus Abies. They are closely related to other coniferous trees in the family Pinaceae such as pines and cedars. Knowing the scientific name of true fir trees can help to identify them.

True firs belong to the genus Abies in the Pinaceae family. They are part of the gymnosperms or “naked seed” plants that evolved millions of years before flowering plants.

Common Name(s): Fir. Distribution: Primarily in mountainous/high-altitude regions worldwide. Genus Size: About 50 species. Mechanical Characteristics: Low density and hardness; generally good strength-to-weight ratio.
