Collaboration is the way the USDA Forest Service operates in this new era, where the challenges in our natural world - to soil, air, plants, animals, watersheds - require the talents of devoted scientists, managers, citizens, communities. Conservation of terrestrial and aquatic ecosystems depends on the success of these networks of involved participants in finding answers to present and future problems. In a 30-year span of time, from 2000 to 2030, a trend shows significant housing density on 57 million acres of private forest land across the United States. The increase in homes will affect public lands, too. Housing density, which translates to higher population, will most likely increase on the 22 million acres of private land that lie within ten miles of a national forest or grassland.
