Evaluation of controlled fertilization of acidified wetlands for enhancement of waterfowl production. / M. Brylinsky
Material type:
TextPublication details: Nova Scotia : 1991Online resources: Abstract: The acidification of freshwater wetlands, through either natural or anthropomorphic processes, can have a drastic effect on the biological habitats and communities contained within these systems. The toxic effects imposed by heavy metals, which become more soluable at low pH,together with the ability of heavy metals to bind with and make unavailable essential plant nutrients, lead to changes in community structure and function that result in systems characterized by very low levels of both primary and secondary production. The problem of wetland acidification is most prominent in industrialized regions of the world where local geomophology, particularly the presence of igneous bedrock of low solubility, leads to water systems having limited buffering capacity. In Nova Soctia it has been estimated that approximately 60 percent of the total land area has terrain characteristics highly sensitive to acid rain and an additinal 25 percent of the landscape has a moderately high sensitivity
