Abstract
The fourth full annual inventory of Minnesota's forest reports 17.6 million acres of forest land with an average live tree volume of 1,156 cubic feet per acre. Aspen is the most predominant forest type in Minnesota, making up 28 percent of the total area. Net growth exceeds removals in the State resulting in a growth to removals ratio (G/R) of 1.7, meaning that forest land is accumulating volume. Fragmentation and parcelization, aging forest cover, as well as threats from native and nonnative pests, are major issues that will impact the future of Minnesota's forests. Information from the National Woodland Owners Survey (NWOS) is also presented in this report. A detailed interactive report is available at https://doi.org/10.2737/NRS-RB-123-INT, and supplemental information, including (1) tables summarizing quality assurance, (2) a core set of tabular estimates for a variety of forest resources, and (3) user and database guides for P2 and P2+ protocols, can be accessed at https://doi.org/10.2737/NRS-RB-123.
