Anthropogenic disturbances and restoration

Novel, reconstructed or degraded ecosystems are increasing in prevalence worldwide. How we manage and restore these ecosystems to be self-sustainable and resilient is a pressing issue. Toward this goal, we study ecological principles underlying forest establishment on reclaimed landscapes previously mined for oil sands. Specifically, we investigate root structure and function of trees establishing on reclaimed areas. These reconstructed ecosystems are novel in the sense there are no natural analogues.
