Using pest and tree photos, tables, and interactive maps, the Forest Health Advisory System provides vital information on future risks to forests across our nation. (U.S. Forest Service)
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.

The shiny green one-half-inch-long, one-eighth-inch-wide emerald ash borer has destroyed tens of millions of ash trees in the U.S. since the beetle’s discovery in 2002 in Detroit.
The real Ash trees comprise around seven percent of the trees in eastern U.S. forests. In urban areas, ash trees make up about 50 percent of street trees.
Ash trees are important both economically and ecologically. A wide array of products are made from ash wood, including baseball bats, tool handles, pool cues, furniture, cabinets, oars, and acoustic and electric guitars. Ash seeds are an important food source for birds, mice, squirrels, and other small mammals. Ash trees also provide essential habitat for cavity nesting birds, such as woodpeckers, owls, and wood ducks. Read more »
