Ohio forests 2016.
This report constitutes the third full report of annualized inventory on Ohio forest land and summarizes field data collected from 2011 through 2016. Ohio has 8.0 million acres of forest land containing 103 tree species and 50 forest types. Net cubic-foot and sawtimber volumes continued to increase, as did the area occupied by large diameter stands. Growing-stock volume remained stable overall, though it decreased 3 percent on private land since 2006. The net-growth-to-harvest-removals ratio dropped from 2.3:1 in 2011 to 1.6:1 in 2016. Invasive insects have had a substantial impact on Ohio's forests, particularly for ash species. Additional information on land-use change, fragmentation, ownership, forest composition, structure, age, carbon stocks, regeneration, invasive plants, insect pests, and the possible future of Ohio's forests is also presented. Sets of supplemental tables are available online at https://doi.org/10.2737/NRS-RB-118 and contain: (1) tables that summarize quality assurance and (2) a core set of tabular estimates for a variety of forest resources.
