Long Term Soil Development (multiple projects)

Two long-term studies were conducted starting in 1992 to assess soil reclamation performance at the Mildred Lake Mine. One study tracked moisture levels across various reclaimed soil designs, revealing that slope position had more influence than capping depth, and vegetation growth didn’t significantly reduce moisture availability. The second examined how bison grazing affected soil properties, showing changes in bulk density, infiltration, and penetration resistance—especially in peat-mineral reclamation covers. Both studies confirm that reclaimed soils maintain stable moisture profiles and can endure moderate grazing pressures.

Reclaimed soil profiles at Mildred Lake support vegetation long-term without major moisture loss. Grazing causes some surface soil changes, but its overall impact is limited and can be managed with smart design and soil selection.
