The publication reviews the ecological information available for patterned boreal peatlands in Northern Minnesota. The report describes the distribution of peatlands, the physical settings in which they exist, and the processes leading to their development on the landscape. Hydrology, water chemistry, and nutrient cycling in bogs and fens are discussed. The plant communities unique to these types of wetlands, their successional trends, and the animal communities inhabiting them are also described. The profile closes with a summary of past human impacts on peatlands and recommendations for future management.
