    By Steve Kemp

    Four research projects focused on bears in the Great Smoky Mountains are currently underway or have recently been completed. Of the four, the results of two are troubling, one is encouraging, and on the last it’s too early to tell.

  2. DLiA’s Science at Sugarlands Focuses on Fish Restoration

    Pat Rakes

    By Frances Figart

    Part of the mission of any national park is protecting and restoring species that were once native. Restoring native fish is an exciting area of Smokies science that goes unseen by those who are not swimming or snorkeling in park waters.

  4. EYS Exotics & Invasives: Larry and the Lady HWAs

    Hemlock Woolly Adelgid

    During my most recent Experience Your Smokies class, I learned the details of a sad story. It all started in 1951, when a seemingly innocent shipment of trees made its way from Japan to Richmond, Va. The trees were intended for used as exotic suburban showpieces. Unfortunately, they carried with them an invasive species that would, in 40 years time, almost completely destroy one of the most ecologically important tree species in Great Smoky Mountains National Park.

  5. “When the Gales of November Came Slashin’*”

    The hurricane-force mountain wave winds that annually torment residents living in the foothills of the Great Smoky Mountains and which contributed greatly to the deadly wildfires in late November 2016 are probably as old as the mountains themselves. Yet much about these winds remains a mystery.

    One reason for the mystery is the scarcity of professional-grade wind measuring equipment (anemometers) in the isolated areas where the wave winds occur. Many official weather-monitoring stations are located at airports because the terrain is flat and unobstructed by trees or man-made structures. The foothills of the Smokies are the opposite of that. The equipment and its power source also must be capable of enduring extremely high winds.

  6. Bird Brain? Not so fast...

    By mid-March, birds like the Louisiana water thrush and the blue-headed vireo will be returning to the Great Smoky Mountains. They will have traveled hundreds of miles, mostly at night — perhaps across the Gulf of Mexico — from as far away as Central America, to their summer home in the Smokies.

    The mystery of precisely how birds navigate on these epic journeys has never been completely solved. Plausible theories have included using the stars to navigate, using magnetic fields, watching landscape features like mountain ranges and coastlines, and their sense of smell. Now a new idea from Dr. Jonathan Hagstrum of the U.S. Geological Survey has the birding world chirping.
