This report presents a summary of the most recent inventory of New Mexico's forests based on field data collected between 2008 and 2014. The results presented here summarize a complete cycle of New Mexico's forest inventory, or 10 years' worth of data collection, whereas the previous report was based only on 9 years' worth of data collected under an accelerated implementation schedule between 2008 and 2012. Therefore, the results presented here are qualitatively and quantitatively similar to those in the previous report; any differences are likely due to sampling error or changes in computational procedures. The report includes descriptive highlights and tables of area, numbers of trees, biomass, volume, growth, mortality, and removals. Most results are organized by forest type or forest-type group, species group, diameter class, or owner group. New Mexico's forest land covers 24.7 million acres. Forty-three percent (10.7 million acres) of this forest land is privately owned, and another 32 percent (7.9 million acres) is administered by the USDA Forest Service. The State's most abundant forest type is pinyon/juniper woodland, which covers more than 10 million acres. Pinyon/ juniper woodlands combined with juniper woodlands cover a total of 13.5 million acres, or more than half of New Mexico's forest land area. Gambel oak is the most abundant tree species by number of trees, followed by common pinyon. Ponderosa pine makes up about one-quarter of the State's total tree volume and biomass, and thus is the most abundant tree species in terms of volume and biomass. New Mexico's forests contain 17.6 billion cubic feet of net volume in trees 5.0 inches diameter and larger. Gross growth of all live trees 5.0 inches diameter and larger averaged nearly 254 million cubic feet per year. Average annual mortality totaled 166 million cubic feet per year, and net growth was therefore 88 million cubic feet per year, or 0.05 percent of the State's total wood volume per year.
