Track of the Grizzly

Track of the Grizzly is the culmination of one of the most ambitious wildlife studies ever undertaken - the Craighead field study of the grizzly bear, carried out in Yellowstone National Park and the huge ecosystem, spanning three states, in which it lies. Over a period of thirteen years, beginning in 1959, Frank Craighead, his brother John, and their colleagues used sophisticated scientific techniques to track hundreds of grizzlies, to discover the bears' social organization and seasonal movements, their breeding and feeding habits, and their life spans. This fascinating book illuminates the shortcomings of America's current system of wildlife management and provides an intimate, detailed, and definitive portrait of the greatest carnivore in our hemisphere.Craighead, Frank C., Jr. is the author of 'Track of the Grizzly', published 1985 under ISBN 9780844661315 and ISBN 0844661317.
