Abstract: The fifth full inventory of Delaware's forests reports an 8 percent decrease in the area of forest land to 352,000 acres, which cover 28 percent of the State's land area and has a volume of approximately 2,352 cubic feet per acre. Twenty-one percent of the growing-stock volume is red maple, followed by sweetgum (13 percent), and loblolly pine (12 percent). All species of oaks combined account for 24 percent of the volume. Red maple is the most abundant species in terms of number of trees and the population had been rising through the 1980s and 1990s, but current data show little change since 1999. Oak species and loblolly pine decreased in numbers of trees and volumes. Seventy-three percent of forest land consists of large-diameter trees and 10 percent is in the small-diameter stand-size classes. Average annual growth as a percentage of total growing-stock volume increased from 2.3 to 3.9 percent between 1999 and 2008, while removals and mortality changed little. Additional information on forest attributes, land-use change, carbon, timber products, and forest health is presented in this report. A DVD included in the report provides information on sampling techniques, estimation procedures, a glossary, tables of population estimates, raw data, and a data summarization and reporting tool.
