Book Description
The calving grounds of the Beverly caribou herd in the Northwest Territories have been delineated over the 23 years between 1957 and 1994 by the Canadian Wildlife Service and the Northwest Territories Department of Resources, Wildlife & Economic Development, and during monitoring for the Caribou Protection Measures. Survey design, criteria for defining the calving ground, timing & coverage of surveys, and weather conditions have varied from year to year. This report maps the Beverly caribou herd's traditional calving grounds from information in the 1957-94 surveys, compiles flight lines & survey strata for each annual calving ground survey into one report, and determines how frequently the Caribou Protection Area covered the annual calving grounds. It also discusses the technical & environmental sources of uncertainty that influence the mapping of the calving grounds.

Book Description
In spite of the harsh conditions that characterize the Arctic, it is a surprisingly fragile ecosystem. The exploration for oil in the Arctic over the past 30 years has had profound effects on the plants and animals that inhabit this frozen clime. The Natural History of an Arctic Oil Field synthesizes decades of research on these myriad impacts. Specialists with years of field experience have contributed to this volume to create the first widely available synopsis of the ecology and wildlife biology of animals and plants living in close association with an actively producing oil field. - First widely available synthesis of arctic oil field ecology and wildlife biology - Concise yet readable treatment of a diverse polar ecosystem - Useful for land managers, policy makers as well as ecologists, and population biologists - Chapters authored by recognized authorities and contributions are peer-reviewed for accuracy and scientific rigor - Illustrations attractively designed to enhance comprehension
