Introduction
The U.
S.
population has grown increasingly urban
each decade, from 28 percent in 1910 to 80 percent in
2000 (U.
S.
Census Bureau, 2002).
In the Chesapeake
watershed alone, residential development is predicted
to consume 800,000 acres between 2003 and 2030,
nearly 90 percent of it replacing farmland (Boesch and
Greer, 2003).
As urban communities grow larger and
faster than ever before, natural resource management
in these areas becomes crucial for achieving sustainable development and maintaining and enhancing the
quality of life and the environment.

storage, 4) improved water quality, and 5) reduced energy consumption.
Trees reduce air pollution by trapping particulate matter in their leafy canopies and by absorbing noxious
pollution into their leaves.
