On Cumberland Island, Carol Ruckdeschel studies the life and death of its endangered creatures. I peer into the cardboard box strapped to the hind rack of her vehicle and discover the source of the gnats’ attraction: the severed head of a loggerhead sea turtle. The ferryboat I’ve taken to Cumberland Island edges up to the Sea Camp dock along the western shoreline. Passengers disembark and mill along the quay outside the visitors’ center. Many of them are her to explore the Cumberland Island National National Seashore, which was established in 1972, or to spot some of the island’s famous “wild” horses; some hope to catch a glimpse of the ruins of Dungeness or other mansions built by the Carnegie family on the southern end of the island in the late nineteenth and early twentieth centuries. But I am here to visit the field biologist Carol Ruckdeschel, a longtime resident of the north end of Cumberland whom I befriended five years ago while working on the island as an environmental educator for the National Park Service. Carol pulls alongside me on her Honda ATV, a cloud of gnats following behind. She appears just as I remember her, with two coffee-colored braids and a pencil attached to her wide-brimmed hat. Carol is in her late fifties, but her lithe body, brisk movements, and inquisitive gaze belie her age. “You’ve got bigger ovaries than me,” she says, referring to my four-day crosscountry drive to get her in a twenty-three-yearold Volkswagen van, which I parked on the Georgia mainland, seven miles west of Cumberland. I peer into the cardboard box strapped to the hind rack of her vehicle and discover the source of the gnats’ attraction: the severed head of a loggerhead sea turtle. “Found this one washed up near the beach at Dungeness,” she says. Wedging my backpack between the rear seat and the box, I slide into the remaining space, and we motor sixteen miles along the sandy road that runs south-north through the island’s humid interior. We pass red bay and live oak trees covered in pink, scab-like patches of “bubble gum” lichen. Two painted buntings flit from the forest’s thick understory and cross the road in front of us, splaying their blue-green, ruby, and lemonyellow wings for an instant before disappearing inside a tress of muscadine grapevines. Spanish moss, not a true moss but a flowering plant in the pineapple family, drapes the oaks and provides nest bedding for the northern parula warbler, white-eyed vireo, and mockingbird. The cabin in which Carol lives with her husband, the herpetologist’s Bob Shoop, is on the north end of the island and is part of an old abandoned neighborhood she calls “the Settlement.” Its population dwindled when the completion of the railroad through Georgia routes and tourists stopped visting Cumberland altered travel routes and tourists stopped visiting Cumberland. All hotel business on the northern end shut down, and the remaining people moved away. Now several small, unpainted wooden cabins in the Settlement contain abandoned tables and chairs and rusted-through coffee cups. As I open the swinging gate to the yard so she can drive through, Carol says, “You can set up your tent at Halfmoon Bluff. I’ll walk you down there. Don’t want you to take a wrong turn and meet up with Ray.” Page 2 Ceiridwen Terrill The Advocate We stroll past the white clapboard First African Baptist Church, which was the place of worship for residents of the Settlement. It was founded in 1893, “He only responds to female voices, and then he expects to be fed.” and, after a fire destroyed the original structure, the current building was erected in the 1930s. Due to a limited budget, the National Park Service focuses its conservation efforts on the southern end of Cumberland, where the ruins of antebellum plantation houses and Carnegie family mansions still stand. The northern end of the island, where most of the residents were poor and black, is all but ignored. Through donations offered by the occasional visitor, however, Carol helps maintain the church as a centerpiece of African-American presence on the island. Soon we enter Halfmoon Bluff, a small clearing overlooking the salt marsh. “Set up your tent there,” Carol says, pointing to a wooden platform under the oaks. I toss my gear down and follow Carol along a faint path through the saw palmetto and leaf litter, careful to avoid brushing against the fronds where ticks wait for a warm body. Cumberland Island is no place for bare legs. We reach an oblong pen that contains a shallow pool of water and black sludge festooned with claw prints. “Ray!” Carol calls out. Turning to me, she explains, “He only responds to female voices, and then he expects to be fed.” The black water stirs, and from the mud comes a sucking sound. Then jaws emerge snapping. Checkered with black squares, Ray’s hide glistens as he swings his head side to side, flashing white, sightless sockets. “What did I tell you? He gets hungry when he hears a female voice.” Ray is the blind alligator that Carol found four years ago, skinny and starving in Christmas Creek. She obtained a permit to take care of him, and since Ray is no longer able to catch prey, Carol will care for him until he dies. “Uh-huh,” I say, unable to muster anything more. Carol feeds Ray fat from the corpses of feral hogs. “Those damn hogs eat dozens of turtle eggs a night. Nothing natural about them. Carnegies and Rockefellers brought them over for sport. When I first came to this island over twenty-six years ago, I don’t think a single nest survived—not one. And there wasn’t a square yard of the island that wasn’t rooted up.” Holding out the handle of a kitchen broom to keep the alligator at bay, she empties the contents of two ten-pound buckets of hog fat and offal into the pen. Carol is brave. Even though Ray is blind, he can hear her movements, and those teeth could tear off her leg. *** Carol came to Cumberland Island first as an undergraduate student doing field research on the island’s lizard species. “I loved it here and wanted to come back,” she says. So she dropped out of school and went to work as a caretaker for the Candler family’s estate on the island. “I’ve been on Cumberland Island ever since,” she says. For the past twenty-five years, Carol has been conducting fieldwork on sea turtles and building the Cumberland Island Museum to house her specimens. The museum, which is adjacent to Carol’s rustic cabin, provides valuable information about the diet, reproductive condition, general health, and taxonomy of the island animals. Skulls, skeletons, and whole specimens line the wooden shelves. The bodies of snakes found dead on the sandy road are now pickled and coiled in Mason jars; alligator hatchlings are preserved in recycled olive jars. These smaller fauna, along with loggerhead sea turtles, double-crested cormorants, porpoise, and numerous bird species, represent each of the island’s ecosystems (salt marsh, maritime forest, ocean, dune, and freshwater lake). All of the museum’s specimens are collected opportunistically, meaning that the animals were found dead rather than killed for analysis. As curators of the museum, Carol and Bob catalog and store the collected specimens. Any carcass in good condition is a candidate for the museum because it has the potential to provide knowledge about the evolution of that island species. The Advocate Ceiridwen Terrill Page 3 “Most people cannot understand why I might want yet another dead blacksnake when I already have four or five pickled,” Carol says. “However, that animal might be from a different time of year, a different sex, have eaten a different food item, and on and on. There is no such thing as having too many animals to look at if you are after a true picture of what is going on here.” Carol and Bob compare notes with other researchers around the country and invite them to use the museum for their own investigations. Despite Carol’s lack of academic credentials, she has been the senior author of a number of scientific papers on sea turtles, and has a reputation for presenting innovative ideas about rare and endangered species at conferences and workshops throughout the country. Her regular monitoring of sea turtle nesting patterns and turtle mortalities makes her uniquely qualified to educate and advise on sea turtle biology and conservation. “I bet we have more loggerhead skulls and skeletal material from the southeast Atlantic coast than anybody else—anybody,” she says. And because species evolve faster on islands due to separation from mainland influences, island geography provides an ideal setting to study evolutionary processes. “The virtue of all wilderness areas is that you learn and observe cycles,” Carol says. “Ecologists watch changes. We know things are changing in the natural world, but we don’t know how these changes occur unless we observe long-term patterns. If we destroy all the naturally functioning systems on the planet, there’s no hope for us to understand these systems and then we’re just playing God.” Though many biologist conduct research on Cumberland, most inhabit a field site only temporarily or seasonally. Carol lives on Cumberland year-round. I ask her why she chose to remain on this particular barrier island to do her research. “I didn’t. It takes most of us so long to find our lifework. Later on, we look back and say, ‘if only I’d seen where I was going back then, I could have had all this time to get my ducks in a row and get down to work soon.’ But that just rarely happens. The real spark is discovering questions about Cumberland’s natural systems that no one knows the answers to. And you know, what matters to me is living in a place where rain counts for the right reasons—not because you might get your panty hose or your shoes muddy, but because rain is critical to gardens and natural communities.” Most days, Carol works from early morning to late afternoon preparing specimens for the museum and performing autopsies (or what naturalists call necropsies) on washed-up loggerhead sea turtles and other wildlife. She also travels the island to count least tern nests, and during nesting season makes monthly boat trips to nearby islands to count pelicans and cranes. A constant advocate for wilderness preservation, she has written letters to Congress since 1965 recommending conservation measures on behalf of Cumberland Island. After dinner, we stack our plates in the kitchen and move to a storage shed, separate from the museum, that is filled with boxes of turtle bones, containers of Lysol bleach, wire scrubbers, and piles of plastic dish drains and fusty crockery. This is where she dissects her specimens. The museum collection helps Carol place wildlife deaths into a larger scientific context, but before she can catalog a specimen, she must first clean, prepare, and label it. This evening Carol begins gluing together the skull plates of a loggerhead. She explains that because juvenile craniums are not fully developed and readily fall apart, she must first bleach away the flesh, and glue the plates securely in place before she can mount the skeletons in the museum. Jagged seams across the skull of another immature loggerhead reveal where the turtle experienced trauma to the head, perhaps from the bludgeon of a shrimper. When it eventually died of the wounds, the turtle washed ashore. Carol maneuvers tenderly around the site of the trauma. Reading glasses perched on her nose, she carefully inscribes in black ink directly onto the bleached surface the species of sea turtle, the date and location found, and the bone type. “The virtue of all wilderness areas is that you learn and observe cycles. Ecologists watch changes.” Sea turtle trail to the nest Page 4 Ceiridwen Terrill The Advocate The specimens that Carol catalogs are stored inside the Cumberland Island Museum, but they may not remain their indefinitely. First African Baptist Church “You know, you just can’t predict what your greatest contribution will be.” When the federal government established Cumberland Island National Seashore in 1972, most private landholders negotiated individual retained-rights agreements. Like many other island residents, only about thirty-three of whom live on Cumberland year-round. Carol sold her property to the government but has the right to live there until her death, at which time the Park Service will claim the property as public land. The agreement does not extend to the lifetimes of spouses or children. But while the federal government will “inherit” Carol’s small cabin, the specimens cataloged and stored inside the museum may be moved to a permanent location where they’ll be available for the next generation of ecologists researching the distinctive ecosystems of this barrier island. I help Carol gather the tagged and separated bones, and we carry them to the museum. We climb the wooden steps and open the front door to a small room used as an office and a library. The smell of formaldehyde wafts through the main collections room. Stacks of science journals and books of peoms, as well as Carol’s publications dating back to the 1960s, line the shelves. An interior door opens into a room of skulls, boxes containing complete sets of bones, and jars of preserved frogs and salamanders. We store the turtle bones in old banana and peach boxes. Carol yawns. It’s about seven in the evening and her bedtime. Retiring early facilitates her pre-dawn scholarly work: reading the latest issues of Marine Ecology and Smithsonian to stay abreast of recent developments in her field and cross-referencing her previous day’s data on three-by-five note cards to look for trends in the island’s ecology. “You know,” she says as we close the museum door behind us, “you just can’t predict what your greatest contribution will be. You just don’t know. When I was younger, I kept thinking that I would get of the animal corpse business. I certainly didn’t get into cataloging dead tur- tles because I loved it. But someone has to record what’s going on here, to try and change things. I keep field notes every day. I also have a separate turtle book. Bob and I thought that when the law went into effect requiring shrimp boats to use TEDS [Turtle Excluder Devices—hatch doors allowing turtles to swim free of shrimp nets] that we’d be out of the turtle business. Everybody did. But nothing changed. Nothing at all.” Carol and I say good night, and I close the yard gate behind me. Several chipped granite headstones leaning against the side of the porch catch my eye. Their written dedications have been gouged out. Carol raised the money to purchase these gravestones, which she placed on the unmarked graves of freed slaves and slave descendants who had lived out their lives on Cumberland. When I arrived, she mentioned the recent vandalism of the burial sites and stressed that the destruction wasn’t random. “Had to be an island resident,” she said. “No one else would care enough to make a fuss.” She has strong suspicions about the culprit’s identity, but resolving to repair or replace the markers and move on, keeps the name to herself. Before continuing down the pathway to Halfmoon Bluff and my tent, I walk up three plank stairs into the First African Baptist Church. There are only eleven simple wooden pews. The building was used as a schoolhouse as well as a place of worship. The whitewashed walls made of plank board brighten the interior of the church, whose dingy windows don’t permit much light. A cross made of sticks fastened together with string marks the front of the pulpit, and a Bible lies open to the Gospel According to Luke. Nearby, a small bench bears a jar filled with coins, where visitors offer spare change for the building’s upkeep. In the fall of 1996, the wedding of the late John F. Kennedy Jr. and Carolyn Bessette took place inside this church. The building was dark, and Carol offered the Kennedy party the use of her oil lantern for the ceremony. I asked her what it was like to witness the wedding of a famous couple in her backyard. The Advocate Ceiridwen Terrill Page 5 “I took my bowl of popcorn and a beer and sat on a milk crate to watch. I would have kicked myself later if I had just gone in the house and worked on my field notes.” Although the wedding was supposed to be a secret, news of it leaked out, and a handful of reporters chartered a boat to the island. One described Carol as “the local eccentric who lives in a broken-down cabin” without electricity or a toilet. In fact, both the museum and her cabin have electric power (which she installed herself). There is even air conditioning in the museum, though she is strict about its use—it’s to protect vital specimens from rot, not for luxury. She and Bob say they don’t use their cabin’s toilet—it was installed for the occasional visiting relative—but she admits to having flushed it once to make sure it worked. Now the seat is stacked with back issues of Smithsonian and Nature. Back at my tent, I zip myself in and flash my headlamp around the wall, swatting any mosquitoes that have tracked me inside. I comfort myself with thoughts of mosquito fish that inhabit the waters of nearby Christmas Creek and Lake Whitney. These two-inch-long fish gorge themselves on mosquito larvae. I hope they are supping blissfully. *** The next morning, I wake up late. It’s Thursday and the day of Carol’s weekly beach survey, a thorough patrol of the seventeen-mile stretch of Cumberland’s beach to take stock of all marine life washed ashore. I quickly pull on my clothes, slap a hat on my head, and run up the pathway to Carol’s cabin. I find her loading the ATV with field equipment for the survey. I know I’ve made a poor start to our fieldwork when Carol hands me two slices of plain bread for breakfast and nods for me to open the gate. She has been awake since 3 a.m. writing summaries of the previous day’s observations. Carol told me once that if she had too many visitors, she would never get her work done. I feel embarrassed at my tardiness. A field biologist’s life is about timing—Carol must get out at the right time of the morning to study marine debris washed in by the tide before it’s lost to the receding ebb. Long pants tucked into white rubber boots, shirt sleeves buttoned at the wrists, and felt hat over her pigtails, Carol is prepared for the scalding sun and mosquitoes. She turns over the Honda’s engine, and we start out. To access the beach, Carol motors the four-wheel ATV along North Cut Road through curtains of gray-green Spanish moss, past houses owned by other private residents. Carol slows, pointing to tracks in the sand that disappear into the duff. They are yellow belly turtle tracks but nowhere near the island’s freshwater ponds. The drought, severe this year, drives land turtles all over the island in search of pools. “You could think of these conditions as bad,” Carol says above the din of the ATV’s engine. Then, slipping into teacher mode, she adds, “but extremes provide the necessary stress for the most effective natural selection.” Although Carol champions Darwin’s theory of natural selection, when we find a wayward turtle at the end of the tracks, she scoops up the animal and drives to South Cut Trail to release it in the stream. We then drive over the dune crossing to the beach, where jackknife clamshells jut out of the sand and plastic Sunny Delight jugs lie half-buried , stranded by low tide. A wavy ribbon of debris marks high tide, and Carol spots a Teva sandal. “Want a pair of sandals?” she asks. “Saw the left foot fifty yards back. Good shape. Someone can use them if they’re too small for you.” She idles the ATV and retrieves the sandals, placing them in the cardboard box bungeed to the hind rack. Terns on Cumberland “You could think of these extremes as bad, but extremes provide the necessary stress for the most effective natural selection.” Page 6 Ceiridwen Terrill In keeping with her conservation efforts, Carol has a use for everything. She salvages lightbulbs the items of marine debris most frequently washed in by the tide, and turns them into Christmas ornaments. She reuses National Park Service envelopes, scratching out the old addresses and stuffing them with new letters. She writes her correspondence to friends and colleagues on the blank side of tossed-out Park Service computer paper. The household garbage she produces in a week’s time fits in a small grocery bag. Hot gusts drub our ears as we drive toward the southern tip of the island. Carol eyes the dun-colored wedge of a turtle’s shell from a distance. When we get closer, she cuts the Honda’s engine and slides off the seat to investigate the scene. “So many of the turtles deaths are a result of shrimp trawlers,” she says. “They scoop up everything. Trawling is like bulldozing a woodland for blueberries.” The turtle’s head is swollen, its throat bloated with putrefied shrimp. “I hate to see this,” she says, shaking her head. “They know they’re killing these damn turtles.” Carol leans over the carcass to ascertain its sex, and my eyes linger on the wrinkled backs of her hands, the folds of skin that stretch lean across the knucklebone. Carol’s hands have had years of practice navigating inside the body cavity of turtles, whales, and birds. Today, she performs a field necropsy. These examinations are a large part of Carol’s field work, and they are perhaps the least pleasant aspect. She has to decapitate the turtles in order to analyze the skulls for trauma. She scrapes off tissue samples and collects the gut contents. Carol traces, with her finger, the slash along the turtle’s throat that was likely caused by the blade of some fisherman’s knife. “What a beautiful animal. God, does it hurt.” With her buck knife, she cuts off the turtle’s head at the nape and places it next to the sandals in the cardboard box, along with a plastic bag containing the turtle’s last meal. Then she drags the carcass to the back dune to prevent the tide from taking it out. She may need to revisit the turtle’s body for more tissue samples. Back at Carol’s yard, black vultures and gnats will peck and nibble the skull clean. Carol’s specimen-collecting is difficult and emotionally taxing. She tells me that at times, large groups of turtles wash up on the beach, causing Bob and her to perform necropsies for twelve to fifteen hours a day on one loggerhead after another. They have also seen whales stranded in the surf fighting for their lives. But with no way to save them, she and Bob could only watch them die. We continue along the strandline and spot an osprey with a mullet dangling from its talons. Least terns hover above schools of olive-colored sheepshead minnow as they slice through the shallows. One after another these birds plunge into the surf and catch the shiny min- The Advocate nows in their sharp beaks. We brake along a wide swath of white sand beach and count the terns. Carol instructs me to tally the birds on our right, while she adds up the ones on our left. Then she plucks the pencil from her hat and jots down the numbers in her field notebook. Her counts of least terns monitor the success of these ground-nesting birds against damage by the island’s feral horses (the horses damage tern nests while grazing on sea oats). The horses on the island are controversial. The popular notion is that they are an indigenous population, or that they may even be left from the Spanish invasions. More likely, however, is that they are leftover stock from the first generation of Carnegies. Within a larger story about conservation, Carol casually mentions her friendship with Jimmy Carter. In the early ‘70s, she says, she helped navigate a stretch of the Chattahoochee River with carter, then the governor of Georgia. She showed him where the river choked on millions of gallons of raw sewage and hot effluent from power plants as it entered Atlanta. Carter was moved to support the preservation of the Chattahoochee not only Carol’s eloquence, but also by the evidence she produced. Since that river ride, the Chattahoochee has been designated a National Recreation Area. But Carol’s efforts do not always result in agency compliance with conservation measures. Perhaps picking up on occasional disputes between Carol and the National Park Service, the popular mystery writer Nevada Barr created a villain in her novel Endangered Species that resembled Carol. Barr, a former Park Service ranger, worked on the island one summer as part of a fire-suppression team. Like Carol, Barr’s character Marty Schlessinger is a sea turtle biologist in her late fifties who lives in a cabin on the north end of Cumberland Island. Unlike Carol, Marty is a murderer, drug addict, and embezzler, using money she acquires for sea turtle research to support her cocaine habit. Carol’s lawyer, Hal Wright, was quoted in the Augusta Chronicle as saying, “Probably the worst thing you can do to a scientist is question what they do with their research funds.” “The thing that gets me,” says Carol, “is that I never even met the woman. Sometime after her book came out, I was down on the south end of the island picking up my mail when a park visitor said, ‘Oh, hey, are you that biologist on the north end?’ and I just thought, ‘Oh, shit. Does this guy think I’m Marty or did he hear something legitimate?’ Visitors have asked some of the park rangers if ‘that biologist Marty’ still lives on the north end of the island. People go screwy. They don’t separate fact from fiction. Not when all the place names are right and Barr’s physical description of Marty exactly matches me.” Page 7 Ceiridwen Terrill Carol filed a libel lawsuit in 1998 against Barr. The parties reached an out-of-court settlement, and the paperback version of Endangered Species features Marty as a man. Other writers have lauded Carol, portraying her as a bright and capable field scientist. John McPhee wrote about her in his 1973 New Yorker profile “Travels in Georgia,” and Anne LaBastille, in her 1980 book Women and Wilderness, praised Carol’s conservation efforts and her commitment to protect the sea turtles. “Carol is her own self-appointed conservation watchdog,” LaBastille wrote. “Nothing escapes her notice—planes flying too low over the beaches, the ran sulfurous stink from air-polluting paper mills nearby…” LaBastille also quoted from a National Marine Fishery Service report, “‘We are compelled to singularly acknowledge the valuable contribution of Carol Ruckdeschel; sea turtles have no greater ambassador.’” The Advocate tub. He beats his wings to cool off, sloshing water over the rim. Six black vultures lurk nearby, and when Duck Duck finishes, two of them hop into the tepid water while the other four press themselves against the ground and pant, their legs stretched out behind them in the shade. For the rest of the afternoon, Carol washes bones, turning the delicate pieces of skeleton over and over in her hands. She scours the ligament oil from hinges and smoothes the bones with her fingers under the purl of the garden hose. Lines etched around Carol’s eyes deepen as she steadies each vertebra between her fingers. “All we have left are islands of wilderness,” she says. “Islands are living laboratories for studying larger systems.” *** Still riding south along the shoreline, Carol brakes the ATV and leans over to loosen three burst balloons from their sand-shingle moorings. The faded lettering reads CAPTAIN D’S SEAFOOD, FARMER’S FURNITURE GRAND OPENING, and HAPPY BIRTHDAY. Helium-filled balloons tear when they reach a certain altitude. When they fall in the ocean, they hang in the water column and resemble jellyfish, a favorite food of sea turtles and other marine life. Balloons and plastic bags lodge in animals’ throats and sea birds’ gizzards where they become a lethal mess. Carol publishes the names of the companies and the messages printed on these scraps of balloon in the Cumberland Island Museum newsletter. We have one stop before heading north up the main road: the Park Service woodpile. We drive under the cabbage palms to the woodpile and winnow through piles of scrap lumber, tricycles, and life preservers dumped by the island’s other residents or their renters. Wild turkeys gawk at us from the shade of a palm. “That timber there,” says Carol, pointing to a dense-looking plank, “that’s a gorgeous piece. You couldn’t buy that today. It’s all fast-grown junk wood. This here is slow grown. Feel how heavy this is.” We gather a few smaller pieces of the good wood and tie them to the ATV. When we return to the Settlement and Halfmoon Bluff, completing a loop of the island, Carol takes the turtle’s head out of the cardboard box and places it beneath tall stems of fennel. Vultures loaf in the year, having picked clean yesterday’s turtle skulls. Carol rewards us with a rest on the cabin porch. We bolt fistfuls of Indian-spiced popcorn—a specialty of Carol’s—and open some beers. Duck Duck—Carol’s pet drake, bathes in the rusty outdoor Cumberland Island beach at low tide *** Nearly finished cataloging vertebrae, Carol calls the work done for the day. It’s almost seven o’clock. As we gather the bones from the floor of the storage room, I ask her why she chose her profession. “Science was my passion—ever since I was a girl,” she says. “And of course, that’s the ideal thing to do when you have a passion: spend your whole life committed to your lifework and get paid for it…My family kept telling me that I’d grow up and forget about toads and frogs and spiders. ‘You’ll outgrow all that,’ they said. And I kept waiting to grow up. Goddamn hurry and grow up. But I couldn’t help myself and finally gave up trying to do what they wanted. I didn’t care anymore. I did what I wanted to do. I had my snakes, and I went in the woods. I’ve always been selfdirected.” Carol is quite for a moment, turning the bones over in her hands. “I’ve gone through some evolutionary processes—in my own thinking and in my way of life,” she says. “I do everything myself. See,” she says, gesturing around at her cabin and at the Cumberland Island Museum, “I don’t have an electrician. I don’t want an electrician. I am the electrician.”
