In 1934, conservationist Aldo Leopold and his wife Estella bought a barn - the remnant of a farm - and surrounding lands in south-central Wisconsin. The entire Leopold clan - five children in all - worked together to put into practice Aldo's "land ethic," which involved ecological restoration and sustainability. In the process, they built more than a pleasant weekend getaway; they established a new way of relating to nature. In 1948, A Sand County Almanac was published, and it has become a beloved and foundational text of the conservation movement. Decades later, Estella B. Leopold, the youngest of the Leopold children - she was eight when they bought the land - now reflects on the "Shack," as they called the repurposed barn, and its inhabitants, and recalls with clear-eyed fondness the part it played in her and her siblings' burgeoning awareness of nature's miracles, season by season. In Stories from the Leopold Shack: Sand County Revisited, she unforgettably recalls the intensity of those days: the taste of fresh honey on sourdough pancakes; the trumpeting arrival of migrating Canada geese; the awesome power of river ice driven by currents - and each description is accompanied by stunning photographs by her brother, A. Carl Leopold. As the Leopolds worked to restore degraded farmland back to its original prairie and woods, they noted and celebrated all of the flora and fauna that came to share the Shack lands. As first evoked in A Sand County Almanac, and now revisited in Stories from the Leopold Shack, the Leopold family's efforts of ecological restoration were among the earliest in the United States, and their work, collectively and individually, continues to have a profound impact on land management and conservationism. All of Aldo and Estella Leopold's children went on to become distinguished scientists and to devote themselves to a life of conservation; their work continues through the Aldo Leopold Foundation. Estella B. Leopold book offers a voyage back to the place where it all began.

Eastern waterfowlers, who know the black duck best, regard this big dusky bird as the top game bird against which all other ducks are measured. In parts of the Northeast this feeling of affection is so strong that in some circles only the black rates the name of "duck." All other species, even the famed canvasback, are "coots," "fish ducks," or are known by even less complimentary titles. Much of this devotion is justified. Without the black duck, wildfowling in much of the thickly settled East would be an unrewarding pastime. Big as a mallard, as wary as a Canada goose, and as handsome in full plumage as any duck that flies, the black duck fills a place on the American sporting scene that could be filled by no other waterfowl. Here is the dramatic story of the life of the black duck, from the time the broods hatch on the spruce-lined ponds of eastern Canada, through the hazardous flights to the southern wintering areas, to the return of the paired birds to the nesting grounds in spring. It is a story told authoritatively by a Canadian scientist whose adult life has been spent in studying the black duck from the fastnesses of its northern breeding grounds in Labrador and Ungava Bay, to the marshes of Louisiana. In this book are facts on the black and other species of waterfowl that will be new to many students of waterfowl as well as to sportsmen. Here also are recommendations for perpetuating the flights of these magnificent game birds.

Field biology is enjoying a resurgence due to several factors, the most important being the realization that there is no ecology, no conservation, and no ecosystem restoration without an understanding of the basic relationships between species and their environments—an understanding gleaned only through field-based natural history. With this resurgence, modern field biologists find themselves asking fundamental existential questions such as: Where did we come from? What is our story? Are we part of a larger legacy? In This Land Is Your Land, seasoned field biologist Michael J. Lannoo answers these questions and more in a tale rooted in the people and institutions of the Midwest. It is a story told from the ground up, a rubber boot–based natural history of field biology in America. Lannoo illuminates characters such as John Wesley Powell, William Temple Hornaday, and Olaus and Adolph Murie—homegrown midwestern field biologists who either headed east to populate major research centers or went west to conduct their fieldwork along the frontier. From the pioneering work of Victor Shelford, Henry Chandler Cowles, and Aldo Leopold to contemporary insights from biologists such as Jim Furnish and historians such as William Cronon, Lannoo’s unearthing of American—and particularly midwestern—field biologists reveals how these scientists influenced American ecology, conservation biology, and restoration ecology, and in turn drove global conservation efforts through environmental legislation and land set-asides. This Land Is Your Land reveals the little-known legacy of midwestern field biologists, whose ethos and discoveries have enabled us to preserve and understand not just their land, but all lands.

This book documents nearly 500 US and Canadian locations where wildlife refuges, nature preserves, and similar properties protect natural sites that lie within the North American Great Plains, from Canada's Prairie Provinces to the Texas-Mexico border. Information on site location, size, biological diversity, and the presence of especially rare or interesting flora and fauna are mentioned, as well as driving directions, mailing addresses, and phone numbers or internet addresses, as available. US federal sites include 11 national grasslands, 13 national parks, 16 national monuments, and more than 70 national wildlife refuges. State properties include nearly 100 state parks and wildlife management areas. Also included are about 60 national and provincial parks, national wildlife areas, and migratory bird sanctuaries in Canada's Prairie Provinces. Many public-access properties owned by counties, towns, and private organizations are also described.
