General: White Fir (Abies concolor) is a coniferous (cone-bearing) tree with flat needles that radiate upward from the twigs. The cones, found only on the upper-most branches, are conical and stand up from the branches (cones of other conifers hang down). The cones fall apart when ripe, leaving upright "spindles" on the branches.

In southern Nevada, White Fir is a common component of the montane vegetation in the Canadian (Pine-Fir Forest) life zone. In southern Nevada, this species is the "Fir" in the "Pine-Fir Forest" and can be found in the highest mountains around Las Vegas (Spring, Sheep, Virgin, Clark, and New York mountains). This species is more common in mountain ranges to the north of Las Vegas.
