“…In Alberta, reclamation following resource extraction requires that soil be placed and vegetation established, by planting and natural colonization [14], such that the site is on a trajectory for return to equivalent land capability, a condition in which the post-disturbance landscape can support pre-disturbance activities [15]. As such, land reclamation represents an area of intensive research, with studies focused on soil placement e.g., [16][17][18] and plant community establishment e.g., [14,19,20], including the potential for ectomycorrhizal fungi to promote seedling establishment e.g., [21][22][23]. In reclaimed areas where soils have been replaced after a period of stockpiling, the soil microbial community, including ectomycorrhizal fungi, is degraded relative to that in adjacent undisturbed areas [21,24].…”
