For New Mexico, estimated merchantable wood volume is expected to increase from 10.052 billion cubic-feet to 10.162 billion (a change of 1.1%), while estimated sawlog wood volume is expected to decrease from 8.23 billion cubic-feet to 7.9552 billion (-3.3%). Estimated merchantable bole biomass is expected to increase from 145.4 million tons to 149.02 million (2.5%), while estimated stump biomass is expected to increase from 7.027 million tons to 7.6779 million (9.3%), and estimated tops and limbs biomass is expected to increase from 26.126 million tons to 60.028 million (129.8%). Finally, estimated aboveground biomass is expected to increase from 184.04 million tons to 223.85 million, a change of 21.6%.

The top ten species in New Mexico in terms of standing biomass are ponderosa pine, Douglas- fir, Engelmann spruce, white fir, quaking aspen, corkbark fir, southwestern white pine, limber pine, blue spruce, and Fremont cottonwood. These species account for 99.4% of the total aboveground biomass and 99.5% of the total merchantable volume. For merchantable wood volume, the species with the smallest percent change was corkbark fir -0.2%, while the largest percent change was with southwestern white pine 10.2%. For total aboveground biomass, the species with the smallest percent change was quaking aspen 9.7%, while the largest percent change was with Fremont cottonwood 52%. For sawlog wood volume, the species with the smallest percent change was ponderosa pine -1.1%, while the largest percent change was with quaking aspen -23.9%. For merchantable bole biomass, the species with the smallest percent change was southwestern white pine 2%, while the largest percent change was with white fir 17.2%. For stump wood and bark biomass, the species with the smallest percent change was blue spruce 2.4%, while the largest percent change was with Fremont cottonwood 42.1%. For top and limb biomass, the species with the smallest percent change was quaking aspen 17.4%, while the largest percent change was with Fremont cottonwood 224.7%.
