Abstract
The mountain pine beetle (MPB) infestation has significantly reduced forest cover, and has the potential to alter snow accumulation in infested basins due to changes in both canopy interception and micrometeorological conditions. Salvage harvesting, prescribed as the current treatment for the MPB epidemic, also impacts snow accumulation and melt by removing forest cover and altering interception, evapotranspiration, and environmental variables such as air temperature, wind speed and incoming radiation. However, the nature and extent of these impacts, particularly the effect of altered snow accumulation on seasonal melt and the onset of peak flow, remain largely theoretical, and are untested with empirical field data. This research specifically examines the impact of MPB infestation on the hydrologic cycle by measuring snow water equivalence (SWE), canopy cover and meteorological variables in a non-infested, infested, and salvage-logged stand within the Vanderhoof Forest District, and projecting the potential impacts on melt and peak flow from these areas.
