They have developed a Marine Debris Database that allows anyone to record and track information about marine debris on land or in the water, or clean-up events. The Forest Service plays an important role in each of the national federal interagency coordinating groups addressing invasive species, including the Aquatic Nuisance Species Task Force (ANSTF), the Federal Interagency Committee for the Management of Noxious and Exotic Weeds (FICMNEW), Federal Interagency Feral Swine Task Force, and the Federal Interagency Committee for Invasive Terrestrial Animals and Pathogens (ITAP). Recent innovations have given scientists even more precise tools to identify new insect or pathogen threats. Entities involved in invasive species management should encourage landowners to consider ecologically-based restoration as part of any plan to manage invasive species. Much as we were unprepared for the virus that has killed more than 450,000 people in the United States and 2.2 million worldwide, were not ready for the next tree pandemic either.

In April 2005, the USFS released its Final Environmental Impact Statement Preventing and Managing Invasive Plants. The potential dangers of new invasions to forestlands, agricultural and range lands, natural areas, and fish and wildlife should be determined as early as possible so that farmers, ranchers, fish and wildlife managers, and conservationists can be forewarned and better prepared.

The cost and difficulty of managing invasive non-native species increases substantially once a species has established self-sustaining populations. The trans-ocean movement of tree species upended things. But the plant spreads quickly, often choking out native wildlife.
