Longleaf pine cornunities were once the most prevalent ecosystem in the Southeastern United States. Conversions of land to agricultural and urban uses and replacement of longleaf with other pine species following logging have drastically reduced the area occupied by longleaf pine. Although longleaf communities can still be found over most of its original range, the species occupies less than 5 percent of its historical acreage, Private individuals own most of the remaining longleaf pine, except in Florida. The private sector is where most losses in longleaf acreage have occurred over the last decade. Because prices and the number of sawtimber-sized trees are increasing, potential harvests in the near future will probably be high. If appropriate information and incentives are not in place, losses of longleaf from private lands could substantially increase.

An analysis of trees in Washington, D.C. reveals that this city has about 1,928,000 trees with canopies that cover 28.6 percent of the area. The most common tree species are American beech, red maple, and boxelder. The urban forest currently store about 526,000 tons of carbon valued at $9.7 million. In addition, these trees remove about 16,200 tons of carbon per year ($299,000 per year) and about 540 tons of air pollution per year ($2.5 million per year). The structural, or compensatory, value is estimated at $3.6 billion. Information on the structure and functions of the urban forest can be used to improve and augment support for urban forest management programs and to integrate urban forests within plans to improve environmental quality in the Washington, D.C. area.
