In this exhilarating installment of the award-winning Scientists in the Field series, journey to the isolated islands of Isle Royale National Park where the longest predator/prey study in the world is being conducted along with a controversial genetic rescue to save not only the wolves and moose, but the entire island ecosystem. On Isle Royale, a unique national park more than fifty miles from the Michigan shore and about fifteen miles from Minnesota, a thrilling drama is unfolding between wolves and moose, the island’s ultimate predator and prey. For over sixty years, in what has been known as the longest study of predator and prey in the world, scientists have studied the wolves and moose of Isle Royale and the island’s ecology to observe and investigate wildlife populations. But due to illness and underlying factors, the population of wolves on the island has dropped while the number of moose has increased, putting the Isle Royale ecosystem in jeopardy. Now, for the first time ever, scientists are intervening. Join celebrated author Nancy Castaldo in this exciting journey to Isle Royale to document the genetic rescue experiment scientists there are embarking on. If they can successfully relocate twenty to thirty wolves from the mainland to Isle Royale, scientists can potentially restore the balance among wolves, moose, and trees of the island's ecosystem. Now the living laboratory experiment begins.

This field study took place in Isle Royale National Park, Canada began in June 1958. There, Meech met Donald E. Murray of Mountain Iron, Minnesota, who served as one of the aircraft pilots for the project. During the 3-year project, the team achieved great things in the aerial observation of wolves and their hunting with a grant from the National Science Foundation.

In this book, we document and evaluate the recovery of gray wolves (Canis lupus) in the Great Lakes region of the United States. The Great Lakes region is unique in that it was the only portion of the lower 48 states where wolves were never c- pletely extirpated. This region also contains the area where many of the first m- ern concepts of wolf conservation and research where developed. Early proponents of wolf conservation such as Aldo Leopold, Sigurd Olson, and Durward Allen lived and worked in the region. The longest ongoing research on wolf–prey relations (see Vucetich and Peterson, Chap. 3) and the first use of radio telemetry for studying wolves (see Mech, Chap. 2) occurred in the Great Lakes region. The Great Lakes region is the first place in the United States where “Endangered” wolf populations recovered. All three states (Minnesota, Wisconsin, and Michigan) developed ecologically and socially sound wolf conservation plans, and the federal government delisted the population of wolves in these states from the United States list of endangered and threatened species on March 12, 2007 (see Refsnider, Chap. 21). Wolf management reverted to the individual states at that time. Although this delisting has since been challenged, we believe that biological recovery of wolves has occurred and anticipate the delisting will be restored. This will be the first case of wolf conservation reverting from the federal government to the state conser- tion agencies in the United States.

Our national parks are more than mere recreational destinations. They are repositories of the nation's biological diversity and contain some of the last ecosystem remnants needed as standards to set reasonable goals for sustainable development throughout the land. Nevertheless, public pressure for recreation has largely precluded adequate research and resource monitoring in national parks, and ignorance of ecosystem structure and function in parks has led to costly mistakes--such as predator control and fire suppression--that continue to threaten parks today. This volume demonstrates the value of ecological knowledge in protecting parks and shows how modest investments in knowledge of park ecosystems can pay handsome dividends. Science and Ecosystem Management in the National Parks presents twelve case studies of long-term research conducted in and around national parks that address major natural resource issues. These cases demonstrate how the use of longer time scales strongly influence our understanding of ecosystems and how interpretations of short-term patterns in nature often change when viewed in the context of long-term data sets. Most importantly, they show conclusively that scientific research significantly reduces uncertainty and improves resource management decisions. Chosen by scientists and senior park managers, the cases offer a broad range of topics, including: air quality at Grand Canyon; interaction between moose and wolf populations on Isle Royale; control of exotic species in Hawaiian parks; simulation of natural fire in the parks of the Sierra Nevada; and the impact of urban expansion on Saguaro National Monument. Because national parks are increasingly beset with conflicting views of their management, the need for knowledge of park ecosystems becomes even more critical--not only for the parks themselves, but for what they can tell us about survival in the rest of our world. This book demonstrates to policymakers and managers that decisions based on knowledge of ecosystems are more enduring and cost effective than decisions derived from uninformed consensus. It also provides scientists with models for designing research to meet threats to our most precious natural resources. "If we can learn to save the parks," observe Halvorson and Davis, "perhaps we can learn to save the world."
