This report summarizes the 2013 results of the annualized inventory of Delaware’s forests conducted by the U.S. Forest Service, Forest Inventory and Analysis program. Results are based on data collected from 389 plots located across the State. There are an estimated 362,000 acres of forest land in Delaware with a total live- tree volume of 936 million cubic feet. There has been no change in the area of forest land since 2008, however, live-tree volume in Delaware has been increasing. Forest land is dominated by the oak/hickory forest-type group, which occupies 53 percent of total forest land area. Seventy-four percent of the forest land area is in large diameter stands, 12 percent in medium diameter stands, and 13 percent in small diameter stands. The volume of growing stock on timberland has been rising since the 1950s and currently totals 811 million cubic feet. Between 2008 and 2013, the average annual net growth of growing-stock trees on timberland was approximately 16 million cubic feet per year. Additional information is presented on forest attributes, ownership, carbon, timber products, species composition, regeneration, and forest health. Detailed information on forest inventory methods, data quality estimates, and summary tables of population estimates are available online at https://doi.org/10.2737/NRS-RB-115.
