Successional reclamation in western Canada: New light on an old subject

Abstract

Successional reclamation is defined as the enhancement of natural successional processes for rehabilitation of drastically disturbed sites. Formulation of grass and legume seed mixes which enhance natural successional processes is described. The use of key pioneering woody plant species and the dynamics of vegetation succession are discussed in the context of reclamation of western Canadian sites. The benefits of using the successional reclamation approach in terms of improved species performance, decreased cost, and enhancement of ecological stability are discussed. Development of bioengineering techniques for use on difficult sites is discussed with reference to techniques, costs and benefits. Key factors in the planning of a successional redamation program are detailed. Examples are drawn from redamation programs conducted at mining and other industrial sites.
