Abies : Abies is a genus of evergreen conifers commonly called firs, native to temperate and mountainous regions of the Northern Hemisphere. Grand fir is one of roughly fifty species in this genus.
Timber : Timber is wood harvested and processed for construction, manufacturing, and other uses. Grand fir is harvested for lumber and pulp, though its wood is relatively soft.
Douglas fir : Pseudotsuga menziesii is a large conifer native to western North America, widely used for timber. Douglas fir often shares forests with grand fir but belongs to a different genus.
Abies grandis var. idahoensis : Abies grandis var. idahoensis is a botanical variety of grand fir associated with inland populations. The variety's name reflects geographic variation within the species.
Climate change : Climate change is a persistent shift in climate patterns, driven in recent times mainly by human greenhouse-gas emissions. Warming and changing precipitation can alter the conditions suitable for grand fir.
Pinaceae : Pinaceae is the conifer family that includes firs, pines, spruces, and several related genera. This family places grand fir among familiar cone-bearing trees.
Christmas tree : A Christmas tree is an evergreen tree displayed indoors or outdoors as part of Christmas celebrations. Grand fir's fragrance and symmetrical form make it a cultivated Christmas tree.
Noble fir : Abies procera is a tall fir native to the Cascade Range and Coast Ranges of the Pacific Northwest. Noble fir is a close relative that overlaps grand fir's range in parts of the Cascades.
Old-growth forest : An old-growth forest is a mature forest with long ecological continuity and structures shaped by many decades or centuries of growth. Grand fir can form part of old-growth forests in the Pacific Northwest.
Wildfire : A wildfire is an uncontrolled fire that burns vegetation and other combustible material in a natural area. Fire can kill grand fir, especially where dense stands and dry conditions increase fire intensity.
