Book excerpt: This summary report provides an overview of findings from the fourth annualized inventory of Iowa forests based on data collected from 2012 to 2018. Forest land area remained stable at 2.9 million acres, and 69 percent of forest land is in the oak/hickory forest-type group. Forests in the State continue to mature, with 72 percent in large diameter stands and 50 percent in stands older than 60 years of age. Total live-tree net volume on timberland is 4.4 billion cubic feet, and 69 percent of that volume is in growing-stock trees. Decreases in gross growth (7 percent) and mortality (2 percent) between 2012 and 2018 resulted in a 14 percent decrease in annual net growth of growing-stock trees to 61 million cubic feet. Additional information on land use change, fragmentation of forest land, ownership, urban forests, species composition, stand structure, forest carbon, down woody material, regeneration, invasive plants, forest pests, tree health, and timber products output are also presented. A detailed interactive report is available at https://doi.org/10.2737/NRS-RB-128-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-128.
