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.

The geographic impact of imported plants

By Faith Campbell, Emeritus environmental advocate and tree-pest expert

As I said in my previous post, the greatest pest risk is associated with imports of whole plants. The U.S. allows few imports of plants in soil; instead, plants must be imported a bare-root stock, which facilitates visual inspection. Still, bare-root plants can also transport a variety of pests and diseases.

GR25: Whitebark pine in 2013


by Jami Westerhold

Welcome Back! As we continue our journey back to 1990, we are bringing you the perilous story of the whitebark pine.

As you will read, 2013 was only one of the many years American Forests worked protecting and restoring the whitebark pine, and if you follow us you may know this story and how our work on this critical species is far from over. That year, American Forests and our partners planted 6,300 trees in an area damaged by wildfir... (Read More)

This year, we will partner with local organizations to plant more than 1.7 million trees in 35 projects in 19 U.S. states and seven countries around the world.

Since its inception 25 years ago, American Forests’ Global ReLeaf program has completed more than 1,000 projects, planting nearly 50 million trees in all 50 U.S. states and 45 countries around the world. These projects are completed in cooperation with local nonprofits, bus... (Read More)
