　　Saving a Forgotten forests The longleaf pine

　　Found only in the Deep South of America, longleaf pine woodlands have �dwindled to about 3percent of their former range, but new forts are under way �to restore them.

　　A The beauty and the biodiversity of the longleaf pine forest are well-kept �secrets, even in its native South. Yet it is among the richest ecosystems in �North America, rivaling tallgrass prairies and the ancient forests of the �Pacific Northwest in the number of species it shelters. And like those two other �disappearing wildlife habitats, longleaf is also critically endangered.

　　B In longleaf pine forests, trees grow widely scattered, creating an open, �park like environment, more like a savanna than a forest. The trees are not so �dense as to block the sun. This openness creates a forest floor that is among �the most diverse in the world, where plants such as many-flowered grass pinks, �trumpet pitcher plants, Venus flytraps, lavender ladies and pineland bog-buttons �grow. As many as 50different species of wildflowers, shrubs, grasses and ferns �have been cataloged in just a single square meter.

　　C Once, nearly 92 million acres of longleaf forest flourished from Virginia �to Texas, the only place in the world where it is found. By the turn of the 21st �century, however, virtually all of it had been logged, paved or farmed into �oblivion. Only about 3 percent of the original range still supports longleaf �forest, and only about 10,000 acres of that is uncut old-growth—the rest is �forest that has regrown after cutting.

　　D Figuring out how to bring back the piney woods also will allow biologists �to help the plants and animals that depend on this habitat. Nearly two-thirds of �the declining, threatened or endangered species in the southeastern United �States are associated with longleaf. The outright destruction of longleaf is �only part of their story, says Mark Danaher, the biologist for South Carolina’s �Francis Marion National Forest. He says the demise of these animals and plants �also is tied to a lack of fire, which once swept through the southern forests on �a regular basis. "Fire is absolutely critical for this ecosystem and for the �species that depend on it," says Danaher.

　　E Name just about any species that occurs in longleaf and you can find a �connection to fire. Bachman’s sparrow is a secretive bird with a beautiful song �that echoes across the longleaf flatwoods. It tucks its nest on the ground �beneath dumps of wiregrass and little bluestem in the open under- story. But �once fire has been absent for several years, and a tangle of shrubs starts to �grow, the sparrows disappear. Gopher tortoises, the only native land tortoises �east of the Mississippi, are also abundant in longleaf. A keystone species for �these forests, its burrows provide homes and safety to more than 300 species of �vertebrates and invertebrates ranging from eastern diamond- back rattlesnakes to �gopher frogs. If fire is suppressed, however, the tortoises are choked out. "If �we lose fire," says Bob Mitchell, an ecologist at the Jones Center, "we lose �wildlife.’

　　F Without fire, we also lose longleaf. Fire knocks back the oaks and other �hardwoods that can grow up to overwhelm longleaf forests. "They are fire �forests," Mitchell says. "They evolved in the lightning capital of the eastern �United States." And it wasn’t only lightning strikes that set the forest aflame. �“Native Americans also lit fires to keep the forest open," Mitchell says. “So �did the early pioneers. They helped create the longleaf pine forests that we �know today."

　　G Fire also changes how nutrients flow throughout longleaf ecosystems, in �ways we are just beginning to understand. For example, researchers have �discovered that frequent fires provide extra calcium, which is critical for egg �production, to endangered red-cockaded woodpeckers. Frances James, a retired �avian ecologist from Florida State University, has studied these small black- �and-white birds for more than two decades in Florida’s sorawling Apalachicola �National Forest. When she realised female woodpeckers laid larger clutches in �the first breeding season after their territories were burned, she and her �colleagues went searching for answers. "We learned calcium is stashed away in �woody shrubs when the forest is not burned," James says. "But when there is a �fire, a pulse of calcium moves down into the soil and up into the longleaf." �Eventually, this calcium makes its way up the food chain to a tree-dwelling �species of ant, which is the red- cockaded’s favorite food. The result: more �calcium for the birds, which leads to more eggs, more young and more �woodpeckers.

　　H Today, fire is used as a vital management tool for preserving both �longleaf and its wildlife. Most of these fires are prescribed burns, �deliberately set with a drip torch. Although the public often opposes any type �of fire—and the smoke that goes with it—these frequent, low-intensity bums �reduce the risk of catastrophic conflagrations. "Forests are going to bum," says �Amadou Diop, NWF’s southern forests restoration manager. "It’s just a question �of when. With prescribed bums, we can pick the time and the place."

　　I Restoring longleaf is not an easy task. The herbaceous layer—the �understory of wiregrasses and other plants, also needs to be re-created. In �areas where the land has not been chewed up by farming, but converted to �loblolly or slash pine plantations, the seed bank of the longleaf forest usually �remains viable beneath the soil. In time, this original vegetation can be coaxed �back. Where agriculture has destroyed the seeds, however, wiregrass must be �replanted.

　　Right now, the expense is prohibitive, but researchers are searching for �low-cost solutions.

　　J Bringing back longleaf is not for the short-sighted, however. Few of us �will be alive when the pines being planted today become mature forests in 70 to �80 years. But that is not stopping longleaf enthusiasts. "Today, it’s getting �hard to find longleaf seedlings to buy," one of the private landowners says. �“Everyone wants them. Longleaf is in a resurgence."
