Volunteers help harvest native seedlings at the Hiawatha National Forest greenhouse in Marquette, Mich. U.S. Forest Service photo.
Biologists have long recognized the important role native plants play in maintaining a healthy forest. When native plants are crowded out by invasive plants, those native species can suffer to the point of extinction.
Since the early 1990s, the Hiawatha National Forest has operated a greenhouse in Marquette, Mich. The idea is to provide both native seeds and seedlings for successful restoration of sites impacted by logging or disturbed by other land management activities. For instance, when aging culverts are replaced, native plants can be introduced to re-vegetate disturbed soil. Seeds and seedlings are also used to enhance existing wildlife habitats. Read more »

You may start out wanting to talk to Leila Pinchot about a U.S. Forest Service icon, but the great granddaughter of Gifford Pinchot has much more to say about the future of another legend, the American chestnut.
One of the seminal figures in world conservation, Gifford Pinchot founded and served as the first chief of the U.S. Forest Service. The eastern forests we know today are distinctly different than the forests Gifford Pinchot would have known 100 years ago – they are missing the American chestnut, which dominated forests in the eastern United States.
Once called the sequoia of the east, the massive tree grew fast and could reach heights of 140 feet. American chestnut not only provided a seemingly endless supply of rot resistant wood, its fruit also fed inhabitants of the eastern United States for millennia. A non-native fungus caused the chestnut blight that killed an estimated 4 billion trees by the middle of the 20th century. Read more »
Mark Twery, a supervisory research forester on the Northern Research Station
How does a former dancer and theater technician end up in a career in forestry? Meet Mark Twery, a supervisory research forester on the Northern Research Station in Burlington, Vt., who is not only all of the above, but loves his unique job that incorporates forestry with dance. Read more »
Boletellus russellii grows under conifers and hardwoods, particularly oaks. It is found throughout most of eastern North America, but is relatively rare. The fungus grows around and actually covers tree roots, producing a fungal "mantle" that helps the tree absorb water and nutrients. (USDA Forest Service Photo)
U.S. Forest Service’s Northern Research Station is breaking out its 79-year-old collection of 20,000 fungus cultures – yes, the stuff that grows in dark, damp places – to help create a new 1,000-species fungal directory. Read more »
