摘要

Research has shown us that both native and introduced plant species are valuable in revegetation and have long been used in range and other cultural practices. Both native and introduced species have more recently been shown to have utility on mined land, especially as revegetation technologies have advanced. This suggests very strongly that the artificial distinction between native and introduced species should be largely disregarded in both theory and practice in mined land reclamation. We must consider each species used in reclamation on its own individual merits, regardless of its place of origin. We must determine how to best use all of the plant materials available to use, includig introduced species--and hybrid crosses of introduced and native species such as those recently developed and tested by Dewey and Asay in Utah. And we need to reexamine the rules and regulations which distinguish between native and introduced species. There have already been changes proposed which would allow use of any plant materials which will achieve the desired goals of specific reclamation plans. Surely the continental origin of a plant species is not as important as its suitability for the purpose at hand. (ERA citation 08:038396)
