Forests are under attack from invasive species, diseases and unprecedented outbreak of pests, while trying to withstand stress caused by climate change and drought. The Midwest is fighting is the invasive species emerald ash borer, which is killing tens of millions of ash trees. New England has seen tens of thousands of trees succumb to the Asian longhorned beetle, which, if it spreads, is estimated to be able to destroy 30 percent of the country’s hardwoods. In the West, millions of trees are being lost to the combined threat of mountain pine beetles and white pine blister rust. Cities across the country have lost tens of thousands of elm trees to Dutch elm disease over the last 60 years. Developing strong management and restoration plans is essential to protecting our forests from invasives, disease and pests.

Our Strategy

Each threat to forests requires us to take a unique approach to solving it.

Through American Forests Global ReLeaf, we work to replant trees, including disease-resistant trees, in areas harmed by disease, insects and more.

Meanwhile, our Endangered Western Forests initiative is helping fight myriad threats to our western forests by planting disease-resistant trees, applying insect-repelling pheromone patches to trees, developing new management plans and more.

Other issues can be addressed more efficiently through policy than field work by trying to prevent future problems, as well as fixing current ones. This approach has led to our efforts in advocating for sustainable forest management, economic incentives for landowners to keep their property forested, and recognition of forests as water resources.

Help for Witness Trees

Trees stand witness to many significant historical moments, often taking on a symbolism of resilience and hope. The witness trees that stand at the Flight 93 National Memorial are such trees. Managed by the National Park Service, this grove of hemlocks is the spot into which Flight 93 crashed on September 11, 2001, when crew and passengers aboard the air... (Read More)




Bats: Out of the Witches’ Cauldron and Into the Fire


by Susan Laszewski
The big brown bat is one of the species of bat at risk of white nose syndrome.

Double, double, toil and trouble!

The witches of Shakespeare’s Macbeth threw several of our forest creatures into their witch’s brew:

Fillet of a fenny snake,
In the cauldron boil and bake;
Eye of newt, and toe of frog,
Wool of bat, and tongue of dog

But this Halloween, some of these creatures have threats other than being mixed into a potion to worry about: disease. For the bat population, white nose... (Read More)




European Ash to Ashes?

By Marcelene Sutter

The current focus of ash tree research in Europe is on finding ash trees that are tolerant or resistant to the fungus outbreak, but Dr. Steve Woodward, a tree pathologist from the University of Aberdeen, says that this approach may not be wholly effective, stating that “the problem with then jumping on as though it’s a great solution to the problem of ash and the loss of ash is that ...
