Trees are often referred to as the lungs of the earth, providing not only the oxygen we need to breathe but a filter to clean our air and water. Trees from forested lands provide timber for our homes, food for people and wildlife, protection from weather extremes and, in urban and rural settings, beautify cities and landscapes alike.

As the largest steward of forested lands in the nation, the U.S. Forest Service works to protect and enhance forest resources not only on National Forests, but on all the Nation’s forests. Our agency puts a lot of effort into safeguarding trees where they grow, but trees are increasingly at risk from fire, changes in climate, insects, diseases and development.

As our nation’s forests grow older and denser they are at greater risk of attack by pests, which can devastate some of more cherished national wildlands. Healthy forests not only provide a beautiful setting for our outdoor activities, they are at lower risk for catastrophic wild fires, and are more resilient to changes in climate and to insect and disease attack.

To address myriad issues facing our nation’s aging landscapes, the U.S. Forest Service has developed the Forest Health Advisory System, a web-based application that highlights potential future activity of more than 40 major forest pests and pathogens across 1.2 billion acres of treed lands.
