Seminar Abstract:
Resource exploration and extraction in the arctic cause long lasting disturbances that affect ecosystem functions and services, and highlight a need for effective revegetation techniques to restore disturbed environments. This research program developed and assessed revegetation techniques for integrated tundra communities with a similar mosaic of species as found in undisturbed areas. Research conducted in the field at Diavik Diamond Mine Inc, Northwest Territories, Canada (Diavik), and in growth chambers at the University of Alberta, focused on propagation and establishment of shrub species and lichen biocrusts, the dominant vegetation in shrub heath tundra in upland areas at Diavik. As very little research of this nature has been done in the north, we conducted a number of studies to develop a baseline understanding of species behaviours under a variety of conditions that can be used to inform current reclamation practitioners and guide future research directions.
