Endangered Species Act Protection Sought for Rarest U.S. Frogs, Turtles and Salamanders- Largest Petition Ever Filed Targeting Amphibians and Reptiles Aims to Save 53 Species in 45 States Press Release from Center for Biological Diversity-July 11, 2012- WASHINGTON D.C. The Center for Biological Diversity and several renowned scientists and herpetologists, including E.O. Wilson and Thomas Lovejoy, filed a formal www.biologicaldiversity.org/campaigns/amphibian_conservation/pdfs/Mega_herp_petition_7-9- 2012.pdf today seeking Endangered Species Act protection for 53 of the nations most threatened species of amphibians and reptiles. The petition the largest ever filed focusing only on amphibians and reptiles asks the U.S. Fish and Wildlife Service to protect six turtles, seven snakes, two toads, four frogs, 10 lizards and 24 salamanders under the Act. Many of Americas frogs, turtles and salamanders are living on the knife edge of extinction. We can only save them if theyre protected by the Endangered Species Act, said Collette Adkins Giese, a Center biologist and lawyer devoted to herpetofauna. Amphibians and reptiles face a profound, human-driven extinction crisis unlike any other. If we dont act now, well lose some of our natural worlds most important and fascinating citizens. Through extensive consultation with wildlife experts, scientists at the Center conducted a coast-to- coast investigation of the countrys most vulnerable but least protected frogs, toads, salamanders, lizards, turtles and snakes. Backed by hundreds of scientific articles, the 450-page petition details the status of, and threats to, 53 amphibian and reptile species in 45 states, demonstrating the urgent need for their federal protection. Habitat destruction, pollution, invasive species and climate change are among the chief threats they face. Some species have lost more than 95 percent of their historic habitat. Among the covered species are the alligator snapping turtle in the Southeast, the wood turtle in the Northeast, Floridas key ringneck snake, the Illinois chorus frog, the Pacific Northwests cascade torrent salamander and Californias western spadefoot toad. We will get serious scientists and general public alike about preserving the diversity of life on Earth only when we have precise knowledge of individual species like those in this petition, said Edward O. Wilson, a distinguished Harvard biologist and Pulitzer Prize-winning author. Future generations will think badly of us if, through ignorance and inaction, we let die this part of their natural heritage. Scientists estimate that about 25 percent of the nations amphibians and reptiles are at risk of extinction, yet only 58 of the approximately 1,400 U.S. species protected under the Endangered Species Act are amphibians and reptiles. The animals in todays petition will reap lifesaving benefits from the Act, which has a 99 percent success rate at staving off extinction for species under its care. So many imperiled species lack the protections of the Endangered Species Act that they need to survive and recover. Mass listing is an excellent way to address biodiversity challenges at scale, said Thomas Lovejoy, a professor of environmental science and policy at George Mason University credited with introducing the term biological diversity to the scientific community. He co-authored a recent www.biologicaldiversity.org/campaigns/amphibian_conservation/pdfs/Gratwicke_et_al_2012.pdf finding that 82 percent of U.S. amphibians that need help are not protected under the Endangered Species Act.
Frogs, lizards, turtles and toads are integral parts of the wild where they live, whether its a remote mountain stream or a suburban wetland, said Adkins Giese. Losing them will impoverish those places and our own connection with the natural world.

Species Highlights Alligator Snapping Turtles (Alabama, Arkansas, Florida, Georgia, Illinois, Indiana, Kansas, Kentucky, Louisiana, Mississippi, Missouri, Oklahoma, Tennessee, Texas): With their heavily armored shells, bear-like claws and powerful beaked jaws its not surprising that these prehistoric-looking turtles have no natural enemies and once thrived throughout the southeastern United States. Early in the 20th century, they were abundant in U.S. river systems draining into the Gulf of Mexico, from the waterways and lakes of the upper Midwest to the swamps and bayous of Florida, Louisiana and Texas. But recent population surveys demonstrate the turtles are now likely extirpated in Iowa, Illinois, Kentucky, Missouri and Tennessee, with declines up to 95 percent over much their historic range from overharvest and unchecked habitat degradation. These slow-moving, largely sedentary behemoths spend so much of their time sitting on river bottoms waiting for food they use a wormlike process on their tongue to lure prey that algae grows thick on their shells. Theyre easy prey for hunters who still look to feed thriving world markets for the exhibition and consumption of the turtles. Wood Turtles (Connecticut, Iowa, Maryland, Maine, Massachusetts, Michigan, Minnesota, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia, Wisconsin): Coveted across much of the world for the colorful red to yellow markings on its neck and legs and the striking geometric growth-line etchings on each of the dark plates that make up its top shell, the wood turtle is considered by many to be the perfect pet. That popularity, from the United States and Europe to Asia, coupled with habitat loss and degradation, has left the wood turtle in serious decline across every state within its range in the northeastern part of the United States. Increasingly hurt by channelization of rivers and streams, careless timber-harvesting practices along waterways, and urbanization and agricultural practices including pesticide use, the turtles remaining populations tend to be isolated, greatly reducing the chances of their natural recovery in areas where their numbers have plummeted. Traditionally low survival rates among juvenile wood turtles have been made worse by the prevalence of turtle predators, such as raccoons and skunks, which thrive in urbanized areas. Wood turtles have an unusual feeding behavior: They stomp their front feet to cause earthworms to come to the surface. Key Ringneck Snakes (Florida): These 6-inch-long, nonvenomous residents of the Florida keys, including Key West and Big Pine Key, could hardly be less of a threat. But the slate-gray snakes with muted neck rings face an ongoing barrage of unmitigated threats to the seaside limestone outcroppings and rockland areas they call home. Largely due to ongoing residential development, the snakes rockland hammock habitat has been reduced by 98 percent, leaving highly fragmented population pockets. Hurt not only by ongoing development but also by malicious killing by humans and predation by invasive species like fire ants, key ringneck snakes face rapid loss across their range. They also face catastrophic threats from climate change, with a sea rise of as little as three feet endangering much of their remaining population. They are listed as threatened in the state of Florida, a status that makes killing and collection illegal but provides no protection from ongoing habitat destruction, the snakes greatest threat. Western Spadefoot Toads (California): These 2-inch-long, stout-looking little toads are known for their purr-like trill, their spade-like adaptation for digging on each hind foot, and for their unusual ability to accelerate metamorphosis when shallow breeding pools start to dry up. But even with those remarkable adaptations, the western spadefoot has been no match for the march of development and habitat reduction. Since the 1950s the animals have lost more than 80 percent of their preferred grassland and alluvial fan habitats. The toads, which are completely terrestrial except when breeding, depend on the existence of vernal rain pools and slow-moving streams, both of which have declined across their range due to urban development and agricultural practices. Historically known to occur in the lowlands of Southern California, from south of the San Francisco Bay area to northern Baja California, they are now listed as a species of special concern in California, a status that recognizes their dramatic decline but fails to afford them any legal protection. Already, they are thought to be extirpated throughout much of their lowland Southern California range. Illinois Chorus Frogs (Arkansas, Illinois, Missouri): Throughout American history, these inch-and-a- half-long, dark-spotted frogs have been known for their distinctive, high-pitched, bird-like whistles that can be heard from great distances. Often mistaken for toads because of their stout bodies, they have thick forearms used for digging burrows. Tiny frogs that spend most of their time below ground, they were once common along the wide, sandy soiled grasslands and floodplains of the Mississippi and Illinois river basins. But as a result of unbridled housing development that has eliminated lowland habitat, and agricultural practices that now level fields instead of leaving the water-holding troughs the frogs used for breeding, most of their already small populations are in serious decline. They are now listed as threatened in Illinois, but this status does not protect their habitat. Yuman Desert Fringe-Toed Lizards (Arizona): These striking little camouflaged lizards, known only to desert sites in southwestern Arizona, have long made their homes in sparsely vegetated areas of windblown sand. Less than 5 inches long, with their tails making up half their length, these extremely rare lizards are highly adapted to the harsh desert environment. The fringe of scales on the sides of their toes helps them run across loose sand without sinking; tightly overlapping eyelids, earflaps and valve-like nostrils protect them from the constantly blowing sand. Their fragile habitat is under ongoing threat from development and off-road vehicles. The lizard is a Bureau of Land Management sensitive species in Arizona and a state sensitive species designations that reflect the lizards rarity but offer no legal protection for them or their habitat. Despite their declining population, lizards may still be taken for personal collections. Kern Canyon Slender Salamanders (California): These 5-inch-long, brown salamanders with black sides and striking bronze and red patches on their backs live only in Californias lower Kern River Canyon. Their restricted range, coupled with ongoing threats of habitat destruction and degradation, leaves them extremely vulnerable to extinction. Known to be uncommon across their range and limited to small, isolated populations, these rare salamanders favor north-facing slopes and small, wooded tributary canyons. Those habitats provide periods of moisture and high humidity that allow the salamanders to emerge from their underground hideouts to forage among leaf debris, bark and loose rocks for a range of food that includes spiders, mites, earthworms and snails. Although nearly all their known populations occur on public lands administered by the Sequoia National Forest, they continue to be threatened by habitat destruction and degradation caused by cattle grazing, logging, mining, highway construction, hydroelectric development and firewood collecting. Cascade Caverns Salamanders (Texas): Perfectly adapted to their wholly aquatic life, these pale, ghost-like salamanders with external gills and recessed eyes spend their entire lives in the darkened worlds of Texas cave springs. Because they breathe through external gills and their skin, these highly unique amphibians require clean, clear-flowing water with a high content of dissolved oxygen. Their health offers an important barometer on water quality. As the human population in Texas continues to soar, the salamanders are at risk from a wide range of environmental hazards. Increased groundwater withdrawals decrease flows into cave springs, resulting in greater temperature fluctuations. More and more pollutants, from pesticides and herbicides to fertilizers and household solvents, are showing up in surface and storm-water runoff that eventually finds its way into the underground springs where these salamanders have long thrived. The salamander is listed as threatened by the state of Texas, a status that prohibits collection but does nothing to prevent water loss and pollution, the biggest threats to the salamander. Peaks of Otter Salamanders (Virginia): Known only to a 12-mile stretch of Virginias Blue Ridge Mountains, Peaks of Otter salamanders have one of the most restricted ranges of any salamander in the United States. These darkly pigmented, 5-inch-long salamanders with brassy metallic spots occur only in mature oak and maple forests at high elevations, a trait that makes them particularly vulnerable to climate change. Because Peaks of Otter salamanders are confined to a single ridge top, they are unable to shift their range upslope as the climate warms. While the habitat of these salamanders is offered some protection in the Jefferson National Forest and on the Blue Ridge Parkway, activities like logging continue to threaten their viability. Cascade Torrent Salamanders (Oregon, Washington): These yellowish-brown, 4-inch salamanders with bulbous eyes and bright yellow bellies inhabit coniferous forests on the west slope of the Cascade Mountains, from southern Washington to central Oregon. They prefer cold, slow-moving streams and can be found in saturated, moss-covered talus or under rocks in waterfall splash zones. Due in part to their extremely reduced lungs, even among salamanders they are considered very intolerant of dry conditions and, as a result, they occur primarily in older forest sites better able to maintain high moisture levels. Not surprisingly, timber harvest hurts torrent salamanders more than many other amphibians, and the ongoing loss of their habitat through logging is well documented.
