This book explores the U.S. forest service plans for responding to climate change. The mission of the Forest Service, U.S. Department of Agriculture (USDA), is to sustain the health, diversity and productivity of the Nation’s forests and grasslands to meet the needs of present and future generations. These services are connected and sustained through the integrity of the ecosystems on these lands. Most of the urgent forest and grassland management challenges of the past 20 years, such as wildfires, changing water regimes and expanding forest insect infestations, have been driven in part by a changing climate and future impacts are projected to be even more severe.
