Can replacing native grasslands with agronomic species improve the above-ground productivity on the Mixed Prairie in Canada?

摘要：

Introduction The relative benefits of introducing forage species to the Northern Great Plains has been examined in well publicized studies with contradictory conclusions.In most cases the research was conducted in trials that were confounded by time of establishment or where the treatments could not be randomized and consequently lacked independence.Therefore,we initiated a study to re-examine the relative productivity between commonly introduced species and native Mixed Prairie communities on the Northern Great Plains.
