Humans adores trees. But humans also migrate and trade, habits that led to the accidental introduction of insects and diseases that harm trees and alter the landscape. Examples are easy to find and may be outside your front door: American elms that once dotted streets across America succumbed to Dutch elm disease. Now all colors of ash species – black, green, white, pumpkin, and blue – are threatened by emerald ash borer. The already uncommon butternut tree, also known as white walnut, faces the possibility of extinction from a mysterious attacker. Many invasive insects and fungi come from regions where native trees have evolved to resist their attacks. When these species enter the United States, they find trees that lack this resistance. There's no immediate end to this dismal pipeline, but there is hope on the horizon.

The Bureau of Land Management has released the final programmatic environmental impact statement for fuels reduction and rangeland restoration in the Great Basin. This programmatic environmental impact statement (PEIS) is intended to further efforts to conserve and restore sagebrush communities within a 223 million-acre area that includes portions of Idaho, Oregon, Washington, California, Nevada and Utah.
Sagebrush communities in the Great Basin are a vital part of Western working landscapes and are home to over 350 species of plants and wildlife. Intact sagebrush communities are disappearing within the Great Basin due to increased large and severe wildfires, the spread of invasive annual grasses, and the encroachment of pinyon-juniper. The Great Basin region is losing sagebrush communities faster than they can reestablish naturally. Fuels reduction and rangeland restoration treatments can reduce fire severity, increase sagebrush communities' resistance to invasive annual grasses and improve their ability to recover after wildfires.

Sometimes reaching a height of more than 100 feet tall with trunk diameters often well over 10 feet, the American chestnut was the giant of the eastern U.S. forests. There were once billions of them and their range stretched from Georgia and Alabama to Michigan, but the majestic tree was gone before forest science existed to document its role in the ecosystem. Notes left by early foresters including Gifford Pinchot, the founder and first chief of the USDA Forest Service, suggest that its ecological role was as impressive as the tree's size. Mature American chestnuts have been virtually extinct for decades. The tree's demise started with something called ink disease in the early 1800s, which steadily killed chestnut in the southern portion of its range. The final blow happened at the turn of the 20th century when a disease called chestnut blight swept through Eastern forests. But, after decades of work breeding trees, The American Chestnut Foundation, a partner in the Forest Service's effort to restore the tree, is close to being able to make a blight-resistant American chestnut available.
USDA. FS. Eastern Region.
The USDA Forest Service Eastern Region is accepting applications for the FY 2022 Landscape Scale Restoration (LSR) competitive grant program. LSR grants achieve the shared priority goals of the Forest Service, states, and sovereign Tribal nations to protect and restore forested landscapes across jurisdictional boundaries.
LSR grants provide vital benefits to the American public. They reduce risk of catastrophic wildfires, improve water quality, restore wildlife habitat, and mitigate damaging insect and disease infestation. State forestry agencies, nonprofit organizations, universities, units of local government, and sovereign Tribal nations are eligible to submit applications. All applications require state forester sponsorship except those submitted by Tribes. Visit the LSR website to learn more about the program and how to apply. Applications must be submitted through grants.gov by November 5, 2021, with additional draft deadlines outlined on the LSR website.
