Abstract
AbstractPeatland development in Canada is influenced by climatic conditions, specifically a north–south temperature and an east–west precipitation gradient, resulting in specific and characteristic kinds of wetlands. The wetland classes (bogs, fens, marshes) are broad ecological units, each composed of distinctive groups of vegetation growing in appropriate habitats. Bogs usually develop in nutrient-poor areas where there is little movement of groundwater, whereas fens occur in more mineral-rich environments having a slowly moving water table. Marshes develop in areas that are periodically inundated by oxygen-rich water. Included within the peatlands are water environments ranging from small puddles to pools, each with a water quality that is influenced by the surrounding peatland.
