The national register of Big Trees: 2002-2003 (A-Y).From the Big Tree DEPARTMENT The controversy has simmered for months: Which is the bigger boldcypress, Louisiana's reigning national champion or Florida's Senator? The issue was not point size (Florida's is 557 points smaller) but whether Louisiana's was a single tree or several grown together. DNA testing has confirmed the Cat island chomp as a single boldcypress, allowing it to keep its crown. The tree has a 644-inch circumference and stands 83 feet tall with an 85-foot average crown spread and a total of 748 points, Issues like this one have led AMERICAN FORESTS to develop a Big Tree Advisory Committee. We'll look to them to improve coordination at the state and local levels and set standards for species eligibility and measurement specifications. Committee members include: state coordinators Pete Smith (Tex.), Kay Fermann (Tenn.), and David Johnson (N.J.); Big Tree hunters Robert Van Pelt, Robert Leverett, and Colby Rucker; Susan Corbett of AMERICAN FORESTS' Historic Tree Nursery; and scientists from the National Arboretum and Chris Luley from The Davey Tree Expert Company. For info, contact Karen Fedor, VP, Global ReLeaf Center at kfedor@amfor.org. Many thanks to McKenzie Clement, a Global ReLeaf Center fellow, for her bard work, patience, and dedication to making the 2002 Register a reality. Karen Fedor

RELATED ARTICLE: Barbara Bosworth AN AMERICAN PORTRAIT Photographer Barbara Bosworth (shown here with her dad) remembers trees hosed on the people she meets along the way. When asked about favorites, she first remembers the forester who helped her or the nearby family who invited her for dinner. Trees also became favorites based on the pictures she takes. One shot (and tree) dear to her heart shows a massive sycamore shading her niece who sits at its base, reading. Bosworth captures on film what most of us feel whoa standing in the shadow of a colossal national champion tree: joy, awe, and an appreciation for nature's wanders. To achieve a crispness and detail not possible with a regular 35 mm camera, Bosworth uses an 8x10 box camera. Using black and white film, she pares down the essence of the tree to simple, beautiful silver tones. Boswarth's pictures capture not only the trees but the environment in which they are found. Over the past 10 years her collection has shown a cross-section of the American landscape. A tree in a backyard with a child's swing, one at a midwestern Missouri crossroads, and a western cedar alone amidst a clearcut--the tree saved due to its national champion status. Her pictures ore a testament to our landscape and bow we hove chosen to use it. Bosworth says she especially loves AMERICAN FORESTS' Big Tree Program and its notional champions because, "America loves the biggest and the best... and everyone loves trees!" McKenzie Clement ADVENTURES IN BIG TREE HUNTING Have you ever been rhododendron surfing (crawling across the tops of rhodies so thick you can't get through them any other way), hiked 11 miles, and then crawled on your hands and knees for two hours to get to your destination or been inside o fence with an angry bull? As Champion Tree Coordinator for Tennessee I have the great pleasure of doing all of these. My name is Kay Fermann and I have served as the state's coordinator for two years. My colleagues joke that I should write a book on bow to survive hunting champion trees because each hunt is a new adventure. Over the past two years I've worked hard with tree hunters and Division of Forestry employees to update Tennessee's Champion Tree Program. The state's list was last published in 1988, and many of those champions have not been seen since 1979. The best advice give tree hunters is to furnish very detailed directions and provide coordinates. That helps me locate the tree and helps the nominator remember where it is. I cannot tell you how many times I've had a nominator say, "I wish I had written down better directions; I think the tree is over there." The best part of being state coordinator is verifying the trees. I have seen several amazing specimens and have been lucky enough to go places very few individuals have seen. Among the trees I've seen, the one that impressed me most was the Notional Champion Pecan, located in Cocke County. This tree sits within 10 feet of a highway in someone's front yard. I wonder what stories it could tell and how it has survived all these years. I have never fell so small as I did that day standing next to this magnificent tree.--Kay Fermann IN THE PRESENCE OF MAGIC I'm sitting at a small table in Room 213 of the Best Western Motel in Covington, Louisiana. On the table next to me ore: three different mops of Louisiana, each with its own strengths and weaknesses; my abused camera bag foil of nearly antique equipment; my glasses that are looking a little rough after I stepped on them earlier today; two film canisters that contain not film, hut vitamin C, aspirin, and antihistamine; a pocket knife; an Arkansas black apple that will serve as dinner; and my thermos cup half full of a cafe au lait that I pieced together with motel coffee and microwave-scorched vending machine milk. Life is good. I'm making some final notes in my fieldbook, a small volume that acts as travel-journal, photo record, and sketchbook. As I reread this past week's entry, it is a litany in Latin: Quercus nigra, Taxodium distichum, Pinus glabra, Pinus taeda, Diospyros virginiana, and a song of praise in English: water oak, baldcypress, spruce pine, loblolly pine, persimmon. I have been in the presence of giants, of magic, and I know that I have been changed in some way because of it. I would approach each tree like the photographer that I am, I suppose, looking for the right angle, the best light, some indication of scale that might help the viewer to put the size into perspective, but at some point, without fail, I would simply leave my equipment and walk aver to the tree and pot my outstretched arms as far around the massive trunk as I could, place my cheek an the cool bark, close my eyes, and just listen. Walking bock to my tripod, I would continue the process of composition, exposure evaluation, dark-slide removal, shutter release, band dark-slide replacement, but more slowly, less frantically. And I would feel less like on intruder looking far something to take and more like a friend. Don House TREES BY THE NUMBERS For as long as I can remember, I've been interested in trees for their size, age, and emotional appeal. Interest in mathematics, science, and history--and a compulsion for absolute numerical accuracy--have shadowed my tree interest end prompted me to document exemplary trees and stands of trees in the East. These compulsions have mixed with science, aesthetics, and sport to culminate in a desire to know the growth capabilities of particular eastern species. But trees are more than just numbers. I came up with the idea for, and helped co-found, the Eastern Native Tree Society (ENTS), which celebrates trees through science, art, music, mythology, history, and even bad puns. I've come to regard trees as metaphors for imagination. They offer us supreme challenges to describe, measure, or draw them or just to sit beneath them in quiet contemplation. My ENTS associates and I have perfected laser clinometer-based techniques for measuring tree heights that give us readings as accurate as expensive laser units. Yet the sheer enjoyment of life among the trees reigns supreme. The highlight of my tree measuring forays has been confirming the 207-foot-tall Boogerman White Pine with Will Blozan in the Cataloochee District of the Great Smoky Mountains National Park. Other highlights include documenting great white pines, American sycamores, tulip trees, eastern cottonwoods, eastern hemlock, and other species. Books, articles, and other publishing efforts keep me focused on the ever-present need to promote trees as life forms of beauty and ecological significance. Robert Leverett ANNE ARUNDEL'S LIFELONG FRIEND When Colby B. Rucker was growing up in Anne Arundel County, Maryland, learning about trees was as natural as going fishing. That natural pastime became a lifelong avocation that has helped recognize and protect many notable trees in his borne county. Rucker started his own tree service in 1956, which he operated for 25 years. Joining American Forests in 1958 prompted him to begin recording interesting trees in the county; over the years that list has grown to thousands of trees from nearly 250 species. Rucker's detailed entries include big trees, old trees, historic trees, unusual trees, and special trues that are no longer standing--trees like Maryland's Liberty Tree, which sheltered revolutionaries. In 1961 he found his first national champion, a Virginia pine, and began contributing nominations to Maryland's Big Tree List. His knowledge and ever-growing tree list ore an invaluable resources, helping save big trees from development and, recently, aiding in the publication of a big tree walking tour for Annapolis. Rocker cautions novices not to overlook the trues growing in their own backyard--not all species grow to extraordinary size. He knows that from experience: he has seven state champions and two notional champs on his land. Rucker retired in 1998 after 17 years as supervisor of grounds for the state capital complex in Annapolis, where his stubborn protection of the state's trees was legendary. With more free time, he's upgraded his measuring arsenal to include laser-based techniques he says are more accurate, provide a better understanding of forest structure, and will increase appreciation and recognition of forest trees. A KNACK FOR TREES Pete Smith I grew up in the shade of big sugar maples and London planetrees on the streets of my Philadelphia neighborhood and became fascinated with all the different kinds of trees an my block. I discovered I had a knack for identifying trees, which led me to forestry school at Peon State. Somewhere during those college years I discovered champion trees. On a trip to central Maine in the mid-80s, two friends and I heard of a national rechampion white pine nearby. After getting directions from the locals we headed into the woods and promptly got lost (remember "The Blair Witch Project"?) but eventually found the tree, about 150 feet toll and straddling a small stream. Its two trunks split about 10 feet off the ground, which probably saved it from the woodsman's ax. I don't know if it ever really was officially a national co-champ, but it's one of my favorite recollections of big tree hooting. My favorite Texas tree isn't even a champ. It's a baldcypress in the floodplain of the Frio River on the aptly named Big Tree Ranch. near Concan. It's unique because it has no visible buttress at the base, simply rising from the ground as a "wall of wood," as one of our foresters puts it. Over the years, the meandering Rio Frio has covered its buttress with 610 feet of rock, silt, and sand, meaning we're measuring it probably 10-14 feet above the original ground line. I wonder how other state champs would stack up if measured the same way! I'd love to see Texas' big tree program create a web-based database for entering and tracking champions, create "virtual tours" of big trees around the state, and have a network of trained volunteer measurers. As more and more people find out about the list, they want more information about specific trees or want to go see the champs. Our greatest challenge is getting them information quickly and accurately. If we can do that, maybe we can turn those with a passing interest into dedicated hunters. Pete Smith A GIANT AMONG HUNTERS Finding a big tree is a combination of preparation, skill, and a little hit of luck. Robert Van Pelt knows that all too well. A champion among Big Tree hunters with 35 current champs and co-champs under his bolt, Van Pelt consults aerial photos, topographic mops, and even friends for tips and clues. A university researcher and author of Pacific Giants, a meticiously documented guide to mammoth western trees, Van Pelt has been hunting the big ones since the early 80s, traveling across the U.S. in pursuit of his quarry. In Pacific Giants he documents notable western trees with text, photographs and his own graceful pen-and-ink drawings. Van Pelt favors "high potential" areas for big tree hunting, whicb often means leaving the beaten trail behind in favor of bushwhacking. One of his more challenging trips--into the Olympic Mountains of Washington-resulted in no new champs but a story of the "Douglas-fir champ that could have been." Van Pelt and a group of friends headed off into Queets Valley, optimistic they would find a Doug-fir he had been tipped off about. The group made their way into the valley, but soon had to leave the marked trail. Off-trail in the northwestern rainforest was tough and the group decided it was not adequately prepared, so they headed back. Van Pelt soon launched another, more-prepared expedition and this time found the tree. Unfortunately, it hod fallen just the winter before. Van Pelt measured it anyway, and found the behemoth, if still standing, would indeed hove been the largest Douglas. fir in the National Register.
