Fire suppression in the Tahoe Basin has caused an excess accumulation of organic debris creating a substantial source of biologically available N and P which can potentially move off-site into adjacent waterways. Wildfire has been found to increase the immediate mobilization of labile N, P, and S resulting in increased nutrient concentrations in surface runoff. Mechanical harvest and/or prescribed burning may offer effective restoration strategies if they can reduce wildfire hazard without adversely affecting discharge water quality. We compare the effects of wildfire, cut-to-length harvest with chip mastication, controlled burning, and untreated controls on potential hydrologic nutrient discharge. Runoff volume, season, and year were identified as important parameters influencing overland flow nutrient concentrations and loads. Higher discharge concentrations were commonly associated with summer rather than winter runoff, but the opposite was true for discharge loads due to the comparative discharge volumes. Treatment (un-harvested, harvested, unburned, burned) effect was shown to be a strong predictor for discharge loads of NO₃-N and SO₄-S, but only a weak predictor for PO₄-P. Discharge loads of both NO₃-N and SO₄-S were greater for the unburned, harvested and the burned un-harvested treatments than for either the unburned un-harvested controls or the burned and harvested treatment. Controlled burning in conjunction with mechanical harvest has the potential to improve long-term runoff water quality by reducing the N and P discharge and improving the overall health of forest ecosystems without the danger of the nutrient mobilization “shock” typically associated with a high intensity wildfire.
