Species breakdown

The top ten species in Nevada in terms of standing biomass are white fir, quaking aspen, bristlecone pine, limber pine, Jeffrey pine, California red fir, subalpine fir, Engelmann spruce, ponderosa pine, and lodgepole pine. These species account for 91.2% of the total aboveground biomass and 91.9% of the total merchantable volume. For merchantable wood volume, the species with the smallest percent change was ponderosa pine 0.4%, while the largest percent change was with limber pine -18.4%. For total aboveground biomass, the species with the smallest percent change was white fir 4.5%, while the largest percent change was with subalpine fir 36.5%. For sawlog wood volume, the species with the smallest percent change was Engelmann spruce -1.7%, while the largest percent change was with limber pine -20.9%. For merchantable bole biomass, the species with the smallest percent change was lodgepole pine -4.3%, while the largest percent change was with limber pine -39.7%. For stump wood and bark biomass, the species with the smallest percent change was Jeffrey pine -4.7%, while the largest percent change was with quaking aspen 55.7%. For top and limb biomass, the species with the smallest percent change was quaking aspen 62.1%, while the largest percent change was with bristlecone pine 359.9%.
