Species breakdown

The top ten species in California in terms of standing biomass are Douglas- fir, white fir, ponderosa pine, redwood, tanoak, California red fir, canyon live oak, Jeffrey pine, incense- cedar, and lodgepole pine. These species account for 78.4% of the total aboveground biomass and 81.6% of the total merchantable volume. For merchantable wood volume, the species with the smallest percent change was Douglas- fir 0.7%, while the largest percent change was with canyon live oak -31.7%. For total aboveground biomass, the species with the smallest percent change was redwood -0.6%, while the largest percent change was with California red fir 33.4%. For sawlog wood volume, the species with the smallest percent change was tanoak -1%, while the largest percent change was with canyon live oak 30.8%. For merchantable bole biomass, the species with the smallest percent change was tanoak -0.6%, while the largest percent change was with canyon live oak -36.7%. For stump wood and bark biomass, the species with the smallest percent change was white fir -0.3%, while the largest percent change was with redwood -44.1%. For top and limb biomass, the species with the smallest percent change was Douglas- fir -21.5%, while the largest percent change was with lodgepole pine 212.4%.
