Strategies for revegetation of disturbed gravel aeas in climate stressed subarctic environments with special reference to Churchill, Manitoba, Canada: a literature review

Abstract

In the vicinity of Churchill, Manitoba, Canada, dry heath tundra is restricted to elevated gravel deposits such as beach ridges and eskers. These sites have been utilized for gravel excavation and extraction as well as for building and road construction. When left alone these gravel areas may remain devoid of vegetation for many decades due to the severity of the climate. Nothing has been done to restore them to their pre-disturbance vegetation cover. This paper reviews literature regarding manipulation of chemical and physical properties of gravel substrates in order to facilitate the development of cover by native plants. A planned revegetation project is presented. -from Authors
