In April 1986, the Chernobyl nuclear power plant in Ukraine exploded and heavily contaminated nearly 40,000 square miles with radioisotopes. The contaminated area became known as the Chernobyl Exclusion Zone in Ukraine and the Polesie Radioecological Reserve in Belarus. Today, the site remains heavily contaminated and access is restricted primarily to staff working to stabilize the remnants of the exploded reactor.

The USDA Forest Service has developed a new risk-assessment tool that helps scientists and decision makers manage natural resources and develop strategies that strengthen ecosystems.

Forest fires often reach or exceed temperatures of 2,000° Fahrenheit—that’s equivalent to one-fifth the temperature of the surface of the sun. What is the impact of such high temperatures on the soil and plants of our forests? And how do the intensity and heat of a wildfire impact its behavior, smoke and the surrounding weather?

The Forest Service manages landscapes, so they are resilient and resistant to threats of all kinds—from fires, to drought, to pest infestations. Forest Service researchers recently confirmed that naturally occurring wildland fire helps create fire-resilient landscapes that limit the start and spread of subsequent fires.

“Resilience” is the ability to recover from change, or when you think about landscapes, the ability to recover from disturbances like wildfires. A new model takes the idea of resilience and applies it to the natural environment, specifically, to sagebrush. This resilience model is one of the core elements of the new Science Framework for Conservation and Restoration of the Sagebrush Biome (Part 2).

Why are Rocky Mountain Research Station scientists sampling tree rings in the Pinaleño Mountains of southeast Arizona? Because tree ring samples reveal the history of fire. When fire scorches a tree, the tree floods its wound with sap, which protects the wound from wood rot decay for hundreds of years, as long as fires keep burning at a low intensity.

“You can’t have a forest without a foundation of quality soil,” said Debbie Page-Dumroese, a soil scientist for the U.S. Forest Service’s Rocky Mountain Research Station in Moscow, Idaho. That’s the lesson learned when hundreds of ponderosa pines were planted on rocky streambanks in national forests—only to die during their first year.

It began as a causal conversation in a hotel lobby in Kansas. After a day of discussions during the annual meeting of the Great Plains Tree Pest Council, the after-hours talk turned to the idea of updating the 1986 Diseases of Trees in the Great Plains manual.

The landscape modeling expertise Samuel Cushman provides as a research ecologist at the U.S. Forest Service’s Rocky Mountain Research Station is in demand worldwide as human-caused disturbances impact animal distribution, connectivity and survival.

Whether it’s clouded leopards in Borneo, lions in Africa, elephants in India, snow leopards in Central Asia or European brown bears, Cushman and his partners study what aspects of the landscape are truly important to animals, how they influence movement and genetic diversity, and which conservation plans will have the most impact.

The greater sage grouse is an iconic bird that lives in the American West's sagebrush landscape. It’s also a species at the center of a nationwide debate focused on how best to manage its habitat to balance multiple uses and ensure the bird’s long-term survival.

And the dialogue has just been informed by new information from a genetics study that has validated the primary target locations of current conservation efforts.
