In December 2013 when Sarah Jovan and Geoffrey Donovan, two scientists with the U.S. Forest Service’s Pacific Northwest Research Station in Portland, Oregon, crisscrossed the northwest area of their city they had no idea they were onto something big. Armed with a ladder and collection equipment, the two spent most of that gray and rainy month carefully plucking hundreds of moss samples off the trunks of the city’s hardwood trees.
They were in relatively uncharted scientific territory, though their research focus seemed straightforward enough: determine if moss, in particular, the ubiquitous Lyell’s orthotrichum moss which grows abundantly across much of the city, could help measure urban air pollution. Read more »

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. Read more »

Preparing for a career involves many steps, plus individual motivation as well as help from those who’ve gone before you.
That’s what a group of 60 Harpers Ferry Job Corps students explored recently during a recent training session related to job preparedness for the U.S. Forest Service. Their hearts and minds were focused on advancing their knowledge about Forest Service job opportunities and how to serve others but also on learning how to help themselves. They were not disappointed. Read more »
Standing in a disturbed patch of forest, Menominee forester Jeff Grignon looks around and explains, “My role is to regenerate the forest, maintain the forest, create diversity, and look toward the future.” This task is becoming increasingly challenging as growing forest health issues intersect with additional stressors brought about by climate change in the forests of the Menominee Nation and elsewhere.
As a leader in forestry and natural resource conservation, USDA has a long history of working with tribes to address their management issues and concerns. Climate change is an active part of that discussion, and has been increasing through development of the new USDA Regional Climate Hubs. The network of Hubs deliver science-based knowledge, practical information, and program support to help natural resource managers, producers, and landowners make climate-informed decisions and then implement those decisions.

It started with a call from a concerned landowner living on Pine Country Lane, nestled in the foothills just west of Denver. The landscape spread out before them was scarred from previous high-severity fires, the homeowners told their local Conservation District.
Their home was sitting at the top of a hill in a tinderbox surrounded by dense forests dying from bark beetle and tussock moth invasions. Decades of fire suppression has altered forests on the Front Range. These forests were historically adapted to frequent low-severity fire and, with suppression, have become fuel-dense and are now comprised of a different species mix. Read more »

The Methow Beaver Project is a bit uncommon as far as forest health restoration projects go, because it relies on one of nature’s greatest engineers – the beaver.
Beavers build dams on rivers and streams, and build homes (“lodges”) in the resulting bodies of still, deep water to protect against predators. Beavers play an important ecological role, because the reservoirs of water that beaver dams create also increase riparian habitat, reduce stream temperatures, restore stream complexity, capture sediment, and store millions of gallons of water underground in wetland ‘sponges’ that surround beaver colonies. This benefits the many fish, birds, amphibians, plants and people that make up the entire ecosystem. Read more »
