The first in-depth examination of the ecological and political significance of the patterned peatlands of Minnesota, one of the largest peatland complexes in the world. Research conducted during the past decade has unraveled many secrets of the intricate peatland ecosystem, unique because it has been so little altered by human action and remarkable for its display of the complex adjustment of living organisms to their environment. The book describes the flora, vegetation, and animal life of the different patterned peatlands and considers the role of surface water and ground water in the development and differentiation of fens and raised bogs. Specific chapters explore the role of mammals, birds, and amphibians and reptiles in the peatland ecosystem.
