Abstract Two releases from steam assisted gravity drainage (SAGD) wellheads occurred 3 yr apart. To track recovery of the affected areas, red‐backed voles were studied 1 and 4 yr later, using population estimates, hepatic detoxification effort, body condition, and tissue metal levels as bioindicators of site recovery. From years 1 to 4, higher ethoxyresorufin‐O‐deethylase induction was no longer evident, capture rate was lower, and body lead residues were no longer (inversely) correlated with body condition.
