Natural History/Regional
The classic account of human impact on this vast wilderness area, now back in print by popular demand!
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.
"A fine, perceptive exploration. . . The wilderness is the Boundary Canoe Area of northern Minnesota, and 'lob trees' are used as a poetic way to link the results of historical and ecological research in this setting. This is a well-illustrated book, built to be carried in hand or pack, as one travels through the lands under discussion." The Canadian Field-Naturalist
"A remarkable book that is well researched, well illustrated, and well written." Inland Seas
"There is no one more qualified than the Ahlgrens to describe the ways human beings have affected the forest of this area." Journal of Forest History
Clifford and Isabel Ahlgren have retired from forest ecology after working many years at the Wilderness Research Foundation in Ely, Minnesota.
