The second full remeasurement of the annual inventory of the forests of New Hampshire was completed in 2017 and covers more than 4.7 million acres of forest land, with an average volume of over 2,300 cubic feet per acre. The data in this report are based on 1,162 plots located across New Hampshire. Forest land is dominated by the maple/beech/birch forest-type group, which occupies 52 percent of total forest land area. Of the forest land, 64 percent consists of large diameter trees, 25 percent contains medium diameter trees, and 11 percent contains small diameter trees. The volume of growing stock on timberland has continued to increase since the 1980s and currently totals nearly 9.5 billion cubic feet. The average annual net growth of growing stock on timberland from 2012 to 2017 was over 180 million cubic feet per year. Additional information is presented on forest attributes, land use change, carbon, species composition, regeneration, and forest health. Sets of supplemental tables are available online at https://doi.org/10.2737/NRS-RB-119 and contain: 1) tables that summarize quality assurance and 2) a core set of estimates for a variety of forest resources.
