Native prairie and savanna once covered vast areas of the U.S. Southeast from Maryland to Texas, but agriculture and sprawl have left only small patches remaining. Now, a new initiative, driven by scientists and local communities, is pushing to restore these imperiled grassland habitats.
Dwayne Estes pulls over to the side of a rural road in Franklin County, Tennessee, about 20 miles from the Alabama border. He hops out of his truck and points out a small plant with dainty, trumpet-shaped white flowers with purple-streaked throats. “This is Penstemon kralii,” says Estes, a 40-year-old, 6-foot-3-inch-tall professor sporting a baseball cap and beard, the twin badges of honor for many field botanists. The plant is found almost exclusively at the base of the Cumberland Plateau escarpment, where it survives precariously in narrow, grassy roadside fringes with other rare and threatened species, including a sunflower and a blue-eyed grass yet to be named and described by scientists.
