A hike through Kentucky’s Red River Gorge is a trip that outdoor enthusiasts never forget. The adventure begins amid rugged terrain with towering sandstone cliffs that contour steep, forested slopes. Visitors discover hundreds of natural stone arches and other unique rock features that create some of the most splendid geological formations east of the Rocky Mountains. Within the beauty and solitude of the gorge resides a rare plant found nowhere else in the world.
The white-haired goldenrod occurs predominantly in the Daniel Boone National Forest, typically found growing along the base of cliffs or on ledges. In areas where the ground is undisturbed, this plant thrives in moist, sandy soil underneath rock shelters. During the fall, the plant blooms with bright yellow flowers along its upper stem. Alternating white-haired leaves line the stem from its base. Read more »

An intrepid fossil hunter on the U.S. Forest Service’s Flathead National Forest in northwest Montana doesn’t need to dig too deep to find exquisitely preserved fossil insects with traces of their original stomach contents. Amazing as this sounds you just need to visit rock outcrops of the Kishenehn Formation exposed on the banks of the Flathead River.
There, researchers affiliated with the Smithsonian’s National Museum of Natural History have discovered a treasure trove of tiny, 46-million year old fossil insects from the Eocene Epoch, which were deposited in sediments of an ancient lake early during the Age of Mammals. The preserved insects—over 7,000 specimens have been collected over the last several years—include fossil mosquitos. At least one specimen preserves an abdomen still engorged from its last meal.

“If you were to tell me three years ago that in two years, I would be camping a couple feet away from a glacier and kayaking next to icebergs, I would tell you that you are out of your mind,” said Isabel Azpilcueta.
But life takes us in unexpected directions, and that is exactly what Isabel – a Chugach Children’s Forest alumni – found herself doing during a Habitat Restoration Kayaking Expedition on the Chugach National Forest, in Alaska. Read more »
Whitebark pine at Crater Lake National Park.
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 »

Last summer, after a flash flood swept through Tbilisi, the capital of the nation of Georgia, the U.S. Forest Service deployed three teams to help address some of the most critical challenges.
The horrific event killed 19 people, forced 67 families from their homes, destroyed roads, and flooded the city zoo. Most of the animals died and the surviving animals wandered the city’s streets. Read more »

The need for food and shelter for wildlife to survive is basic, particularly for sage grouse living in a post-wildfire landscape in western states. The U.S. Forest Service is helping this upland game bird survive by growing about 3 million sagebrush shrubs a year to restore the area’s dry, grassy plains, essential for the bird’s nesting grounds.
“Our goal is to help accelerate the restoration process on our public lands,” says Clark Fleege, manager of the Lucky Peak Nursery, part of the Boise National Forest. Read more »
