sentences: Arceuthobium abietinum is a species of dwarf mistletoe known as fir dwarf mistletoe.
 It is native to western North America from Washington to New Mexico to northern Mexico, where it lives in coniferous forests as a parasite on various species of fir, particularly white fir, giant fir, and red fir.
 This is a small shrub which is visible as a network of scaly yellowish stems extending above the bark of its host tree.
 Most of the mistletoe is located inside the host tree, attached to it via haustoria, which tap the tree for water and nutrients.
 The leaves of the mistletoe are reduced to knobby scales on its surface.
 It is dioecious, with male and female mistletoe plants producing spikes of staminate and pistillate flowers, respectively.
 The fruit is a sticky berry a few millimeters long which explodes to disperse the seeds it contains several meters away from the parent plant and its host tree.
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".
Abies magnifica, the red fir or silvertip fir, is a western North American fir, native to the mountains of southwest Oregon and California in the United States.
 It is a high elevation tree, typically occurring at 1400 - elevation, though only rarely reaching tree line.
 The name red fir derives from the bark color of old trees.
Pseudotsuga menziesii, commonly known as Douglas fir or Douglas-fir, is an evergreen conifer species native to western North America.
 One variety, the coast Douglas fir, grows along the Pacific Ocean from central British Columbia south to central California.
 A second variety, the Rocky Mountain Douglas fir, grows in the Rocky Mountains from British Columbia south to Mexico.
 The tree is dominant in western Washington.
 It is extensively used for timber, worldwide.
The Red Creek Fir is a Douglas fir tree, at least 1000 years old, standing near Port Renfrew on Vancouver Island in British Columbia, Canada.
 With its diameter of 4.2 meters (13.8 feet) and height of 73.8 meters (242 feet), it is the largest Douglas fir in the world.
 Note it is not the tallest in Canada (MacMillan Provincial Park houses a specimen 10 meters (33 feet) taller) but it does contain more wood than any other known Douglas fir.
Imperata is a small but widespread genus of tropical and subtropical grasses, commonly known as satintails.
Christmas tree production occurs worldwide on Christmas tree farms, in artificial tree factories and from native strands of pine and fir trees.
 Christmas trees, pine and fir trees purposely grown for use as a Christmas tree, are grown on plantations in many western nations, including Australia, the United Kingdom and the United States.
 In Australia, the industry is relatively new, and nations such as the United States, Germany and Canada are among world leaders in annual production.
Abies procera, the noble fir, also called red fir and Christmastree, is a western North American fir, native to the Cascade Range and Coast Range mountains of extreme northwest California and western Oregon and Washington in the United States.
 It is a high altitude tree, typically occurring at 300 - altitude, only rarely reaching tree line.
Fir and spruce forests are greatly affected by slight fluctuations in climate.
 Temperature is the primary determinate for spatial patterns of fir and spruce.
 The two dominant trees in this type of forest are "Picea engelmannii" (Engelmann spruce) and "Abies lasiocarpa" (subalpine fir).
 Although thick-barked trees, such as the "Pinus resinosa", frequently survive fire, the thin bark of spruce make them more vulnerable.
 Trees such as the Douglas fir withstand much of the fire due to the thicker bark they have.
 The scale of the burn mosaic during a fire, relative to species niche requirements and mobility, can have major impacts on flora and fauna dynamics.
Abies concolor, commonly known as the white fir or Colorado white-fir, is a fir native to the mountains of western North America, occurring at elevations of 900 – .
 It is a medium to large evergreen coniferous tree growing to 25 – tall and with a trunk diameter of up to 2 m .
 It is popular as an ornamental landscaping tree and as a Christmas tree.
 It is sometimes called concolor fir.
