Decades of fire suppression, as well as changing land management practices, have caused vegetation to accumulate and become altered on federal lands. Concerns about the effects of wildland fires have increased efforts to reduce fuels on federal lands. These efforts also have environmental effects. The requesters asked GAO to (1) describe effects from fires on the environment, (2) assess the information gathered by the Forest Service and Bureau of Land Management (BLM) on such effects, and (3) assess the agencies approaches to environmental risks associated with reducing fuels. This report recommends that the Secretaries of Agriculture and the Interior (1) develop a plan to implement the agencies monitoring framework, (2) develop guidance that formalizes the assessment of landscape-level risks to ecosystems, and (3) clarify existing guidance, working with the Council on Environmental Quality (CEQ), to assess the risks of environmental effects from reducing fuels.

The Forest Service, within the U.S. Dept. of Ag., manages over 190 million acres of forest and grassland. The agency is responsible for managing its lands for various purposes -- including recreation, grazing, timber harvesting, and others -- while ensuring that such activities do not impair the lands' long-term productivity. Carrying out these often competing responsibilities has been made more difficult by the increasing cost of wildland fires and the budgetary constraints necessitated by our nation's long-term fiscal outlook. This testimony highlights some of the major management challenges the Forest Service faces in carrying out its responsibilities. It is based on numerous reports issued on a wide variety of the agency's activities.

Since 1997, the Ecosystem Management Decision Support (EMDS) system has been used around the world to support environmental analysis and planning in many different application areas, and it has been applied over a wide range of geographic scales, from forest stands to entire countries. An extensive sampling of this diversity of applications is presented in section 2, in which EMDS application developers describe the varied uses of the system. These accounts, together with the requisite background in section 1, provide valuable practical insights into how the system can be applied in the general domain of environmental management.
