Lob Trees in the Wilderness by Clifford Elmer Ahlgren,Isabel Ahlgren Pdf
Along the Minnesota-Ontario border, in the days of voyageurs, tall trees were used as guideposts in the uncharted wilderness to help fur traders and explorers find their way through the maze of lakes and portages. Branches were cut, leaving the middle of the tree bare with branches above and below. Clifford and Isabel Ahlgren, two of the most knowledgeable ecologists of the area, use nine native trees to serve as lob trees for this book, an ecological history of human activity in the Quetico-Superior wilderness area.

Wild Forests by William S. Alverson,Don Waller,Walter Kuhlmann Pdf
Wild Forests presents a coherent review of the scientific and policy issues surrounding biological diversity in the context of contemporary public forest management. The authors examine past and current practices of forest management and provide a comprehensive overview of known and suspected threats to diversity. In addition to discussing general ecological principles, the authors evaluate specific approaches to forest management that have been proposed to ameliorate diversity losses. They present one such policy -- the Dominant Use Zoning Model incorporating an integrated network of "Diversity Maintenance Areas" -- and describe their attempts to persuade the U.S. Forest Service to adopt such a policy in Wisconsin. Drawing on experience in the field, in negotiations, and in court, the authors analyze the ways in which federal agencies are coping with the mandates of conservation biology and suggest reforms that could better address these important issues. Throughout, they argue that wild or unengineered conditions are those that are most likely to foster a return to the species richness that we once enjoyed.
With more than 200,000 visitors annually, the Boundary Waters Canoe Area Wilderness is among the most alluring wilderness areas in the country, unique because it is most often explored by canoe. Comprised of more than one million acres, the BWCAW is an exceptional combination of expansive wilderness, abundant wildlife, and fascinating natural and human history. Exploring the Boundary Waters is the most comprehensive trip planner to the BWCAW, giving travelers an overview of each entry point into the wilderness area as well as detailed descriptions of more than one hundred specific routes—including a ranking of their difficulty level and maps that feature the major waterways, portages, and the designated campsites. The book is crafted so that readers can design their own route through the almost inexhaustible network of lakes and streams. Daniel Pauly, Boundary Waters expert, worked with the U.S. Forest Service, the Minnesota DNR, and local outfitters to collect and present crucial information here: instructions on about how to obtain a permit, the rules and regulations of the park, safety tips, and suggestions about how to help maintain the ecological integrity of the wilderness. As engaging as it is informative, Exploring the Boundary Waters not only contributes advice on the pros and cons of each route, but also brings the reader a natural and historical context for the journey by offering insight into the pictographs, mining sites, logging railroads, and ruins one may encounter on an expedition. With its accessible and personal style, Exploring the Boundary Waters is the perfect guide for anyone—novice or seasoned veteran—arranging a trip to the BWCAW. A companion Web site for this book, http://www.boundarywatersguide.com, presents useful information that can be downloaded for planning a trip, including gear lists, overview maps, and route updates.
Quetico Park in northwestern Ontario celebrates its 100th anniversary in 2009. Long-recognized as a gem among parks, Quetico contains some of the largest stands of old-growth red and white pine in Canada , as well as a diversity of fascinating lichens, carnivorous plants in specialized habitats. The author presents an insightful look into Quetico’s natural history as he examines the adapations that have allowed moose, white-tailed deer, wolves and other mammals to survive. The human history of the park is also explored, beginning with the Objiwa living there when the area was designated as a park, followed by accounts of trappers, loggers, miners, park rangers, and poachers. Beginning with the retreat of the glaciers, the author combines his thorough research into Quetico’s long and varied history with the threads of his own extensive involvement with the park. The result is a splendid tribute to a very special place.
Since its introduction in 1979, CHEAPO, a computer based economic analysis program, has allowed users of the Stand Prognosis Model to evaluate silvicultural alternatives from an economic point of view. Subsequent modifications to the Prognosis Model have rendered CHEAP0 obsolete. This users guide covers a new computer model, CHEAP0 II, which is compatible with version 5.1 of the Prognosis Model and expands its economic analysis capabilities.

Mastering the Inland Seas by Theodore J. Karamanski,Theodore Karamanski Pdf
Theodore J. Karamanski's sweeping maritime history demonstrates the far-ranging impact that the tools and infrastructure developed for navigating the Great Lakes had on the national economies, politics, and environment of continental North America. Synthesizing popular as well as original historical scholarship, Karamanski weaves a colorful narrative illustrating how disparate private and government interests transformed these vast and dangerous waters into the largest inland water transportation system in the world. Karamanski explores both the navigational and sailing tools of First Nations peoples and the dismissive and foolhardy attitude of early European maritime sailors. He investigates the role played by commercial boats in the Underground Railroad, as well as how the federal development of crucial navigational resources exacerbated sectionalism in the antebellum United States. Ultimately Mastering the Inland Sea shows the undeniable environmental impact of technologies used by the modern commercial maritime industry. This expansive story illuminates the symbiotic relationship between infrastructure investment in the region's interconnected waterways and North America's lasting economic and political development.

An extraordinary illustrated biography of a Métis man and Anishinaabe woman navigating great changes in their homeland along the U.S.–Canada border in the early twentieth century John Linklater, of Anishinaabeg, Cree, and Scottish ancestry, and his wife, Tchi-Ki-Wis, of the Lac La Croix First Nation, lived in the canoe and border country of Ontario and Minnesota from the 1870s until the 1930s. During that time, the couple experienced radical upheavals in the Quetico–Superior region, including the cutting of white and red pine forests, the creation of Indian reserves/reservations and conservation areas, and the rise of towns, tourism, and mining. With broad geographical sweep, historical significance, and biographical depth, Making the Carry tells their story, overlooked for far too long. John Linklater, a renowned game warden and skilled woodsman, was also the bearer of traditional ecological knowledge and Indigenous heritage, both of which he was deeply committed to teaching others. He was sought by professors, newspaper reporters, museum personnel, and conservationists—among them Sigurd Olson, who considered Linklater a mentor. Tchi-Ki-Wis, an extraordinary craftswoman, made a sweeping array of necessary yet beautiful objects, from sled dog harnesses to moose calls to birch bark canoes. She was an expert weaver of large Anishinaabeg cedar bark mats with complicated geometric designs, a virtually lost art. Making the Carry traces the routes by which the couple came to live on Basswood Lake on the international border. John’s Métis ancestors with deep Hudson’s Bay Company roots originally came from Orkney Islands, Scotland, by way of Hudson Bay and Red River, or what is now Winnipeg. His family lived in Manitoba, northwest Ontario, northern Minnesota, and, in the case ofJohn and Tchi-Ki-Wis, on Isle Royale. A journey through little-known Canadian history, the book provides an intimate portrait of Métis people. Complete with rarely seen photographs of activities from dog mushing to guiding to lumbering, as well as of many objects made by Tchi-Ki-Wis, such as canoes, moccasins, and cedar mats, Making the Carry is a window on a traditional way of life and a restoration of two fascinating Indigenous people to their rightful place in our collective past.
