Nature Conservancy Scientists Rank Natureâ€™s Greatest Past and Future Comebacks
The Conservancy Identifies Top Nature Resurgences
Arlington, VA (PRWEB) October 27, 2011
Decades ago, few would have predicted that bald eagles would be a common sight over the Potomac River in the 21st Century. But as The Nature Conservancy celebrates its 60th anniversary this month, eagles are among the top 10 success stories of modern conservation, as identified by Conservancy scientists in a new report.
Ã¢Å“Nature is resilient,Ã¢ said M. Sanjayan, lead scientist for The Nature Conservancy. Ã¢Å“With a little help, animals, landscapes and even the air that we breathe can come back from the brink of disaster. These amazing comeback stories give me hope for the future of our world.Ã¢
Someday, weÃ¢ll be talking about stories like the miraculous return of salmon to American rivers, the restoration of floodplain ecosystems and the amazing recovery of the Yunnan golden monkey in the forests of China, which Sanjayan and other Conservancy scientists predict will be the next great comebacks:
- Salmon species native to both the Atlantic and Pacific have been pushed to the brink, struggling to battle dammed and polluted rivers, a warming climate and fishing pressure at sea. But there are signs of progress: In Maine, migratory runs of federally protected Atlantic salmon runs reached record numbers this fall and dam removals will restore key habitat. And on the West Coast, where salmon are critical to the entire Pacific Coast ecosystem, the Conservancy is involved in more than 50 restoration projects across five states and Canada, including an innovative project to restore habitat for coho salmon in California thatÃ¢s already showing results.
- ChinaÃ¢s Yunnan golden monkey is one of the worldÃ¢s most endangered primates, with no more than 2,000 remaining. Habitat loss and illegal hunting have pushed the monkey to the brink of disaster. But with the help of local people and Conservancy biologist Long Yongcheng who is tracking the elusive creatures the monkey is making progress.
- Much floodplain land in the United States has been lost to farming or development, but reconnecting floodplains with their rivers can be an effective and low-cost way to reduce flooding and protect habitat. WeÃ¢re working to restore elms along the Connecticut River, and studying past Mississippi River floods to better understand river behavior.
NatureÃ¢s Top 10 Greatest Comebacks of the 20th Century
Bald Eagle: The national symbol of the United States is also a sign of survival. In the mid-20th Century, eagles were driven to the edge of extinction due to hunting, habitat loss and pesticide contamination that harmed their ability to hatch chicks. Eagle populations began to rebound after the pesticide DDT was banned in the United States in 1972. Today, there are an estimated 10,000 nesting pairs in the United States.
Gray Wolf: Top predators in many parts of the world, little threatens a wolf. But as agriculture expanded across the Midwest in the 20th century, thousands of wolves were killed for being a threat to livestock, as much of their habitat became farms and towns. Following their listing on the Endangered Species List in 1974, wolf populations began to bounce back in the Great Lakes region. Today there are estimated to be more than 4,000 wolves.
Eastern Forests of the United States: Large swaths of the eastern United States are more forested today than they were in the 1800s. ItÃ¢s estimated that less than 48 percent of the maple, oak, cedar, pine, hemlock and more that once stretched from Maine to Florida and east to Texas and the Great Lakes was gone by 1900. The 1911 Weeks Act created 48 national forests, protecting 20 million acres, and in recent decades working forest conservation easements have helped keep millions of additional acres of private land forested.
Mauritius Kestrel: The story of the Mauritius Kestrel is probably the most remarkable conservation success story youÃ¢ve never heard. In 1974, this small bird of prey that lives on an island off the coast of Africa was considered the rarest bird in the world Ã¢“ there were just four of them. But two conservationists established a wildlife sanctuary, and their captive breeding program helped the kestrel population recover. By the mid-1990s there was a self-sustaining population, and today there are more than 800 mature birds.
Cuyahoga River Valley & Lake Erie: Following decades of industrial pollution, the Cuyahoga River Valley and Lake Erie were once devoid of most aquatic life. In the 1950s and 60s, the river actually caught fire several times and TIME magazine dubbed it Ã¢Å“the river that oozes rather than flowsÃ¢. But these systems have been brought back to life, fisheries are rebounding and Ohioans are again enjoying the river, thanks in large part to the Clean Water Act.
Gray Whale: The International Whaling CommissionÃ¢s moratorium on commercial whaling may have saved gray whales from extinction. Gray whales make one of the longest migrations of any animal Ã¢” more than 12,000 miles from their winter breeding grounds in Baja, Calif., to their summer feeding grounds near Alaska. In the 19th Century, gray whales were hunted to near extinction. Since then, gray whale numbers have rebounded to an estimated 22,000 animals.
Clean Air: Depending on where in the United States you live, your intake might be fresher than others. But itÃ¢s probably far better than it could have been, thanks to the 1970 Clean Air Act. Air pollution has always been an issue and probably always will be, as long as humans are driving, flying, farming and manufacturing. But with the passage of the Clean Air Act, the quality of the air we breathe became a right that must be protected.
Santa Cruz Island Fox: Until the 1990s, the tiny, 4-pound Santa Cruz Island fox ruled the small island off the coast of California. Then came the pigs. The feral pigs attracted golden eagles, who also snacked on the foxes. By 2002, fewer than 100 remained Ã¢Ë†´ until The Nature Conservancy, together with the National Park Service, U.S. Fish and Wildlife Service and the California Department of Fish and Game, initiated a captive breeding program. Today, the population is up to 1,300.
Grizzly Bear: The story of grizzly bears in the western United States is one of cautious optimism. Like many species, hunting and habitat loss took a toll as settlers moved West. By 1970, their numbers were low enough to earn them threatened status in the lower 48 states. Now their numbers are up to 600 near Yellowstone National Park and they just might be taken off the threatened list.
Southern White Rhino: Near the verge of extinction in the 1800s, the southern white rhino is now considered the most abundant rhino in the world. Their story is much like that of the American bison. They once grazed huge swaths of grassland, but were decimated by widespread hunting. By the late 1800s, the southern white rhino was on the verge of extinction. Today, thanks to decades of work by conservationists and researchers, their numbers are above 20,000.
The Nature Conservancy is the leading conservation organization working around the world to protect ecologically important lands and waters for nature and people. To date, the Conservancy and its more than one million members have been responsible for the protection of more than 18 million acres in the United States and have helped preserve more than 117 million acres in Latin America, the Caribbean, Asia and the Pacific.
