Purpose: For centuries, humans have inadvertently been contaminating peatlands due to industrial emission of pollutants that degrade key peatland ecosystem functions, such as carbon sequestration. Returning the ecosystem functionality to these degraded peatlands remains a challenge due to adverse ecohydrological conditions and elevated peat pollutant concentrations, such as nickel (Ni) and copper (Cu), at the remnant peat surface. However, field-scale trials can be labour, time, and monetarily expensive with no guarantee of success. As a precursor to field-scale trials, we use a 10-year coupled hydrological and solute transport models in Hydrus-1D to assess the feasibility of using peat-block transplants to restore a peatland contaminated by Ni and Cu. The exceedance of critical capitula hydrological (soil water tension >100 mbar) and chemical ([Ni] and [Cu] > 10−6 mmol mL−1) thresholds that correspond with increased Sphagnum physiological stress were assessed using a series of modelled scenarios with varying peat-block thicknesses (5 to 30 cm in 5 cm increments), Sphagnum species (S. fuscum, S. rubellum, S. magellanicum, and an average Sphagnum), and initial contaminant loads (i.e., distance from a smelter).
