RT Journal Article T1 Windthrow in riparian buffers affects the water quality of freshwater ecosystems in the eastern Canadian boreal forest A1 Guimond, Michel A1 Grosbois, Guillaume A1 Waldron, Kaysandra A1 Montoro Girona, Miguel AB Despite the wide application of riparian buffers in the managed boreal forest, their long-termeffectiveness as freshwater protection tools remains unknown. Here, we evaluate windthrow incidencein riparian buffers in the eastern Canadian boreal forest and determine the effect of windthrow onthe water quality index of the adjacent freshwater ecosystems. We studied 40 sites—20 riparianbuffers, aged 10 to 20 years after harvesting and 20 control sites within intact riparian environments—distributed among clay and sandy (esker) soils and black spruce (Picea mariana) and jack pine (Pinusbanksiana) stands. We observed more windthrow in the harvested stands (36%) relative to thecontrol sites (16%), regardless of substrate and species. We determined that the most importantfactors explaining windthrow were exposition, harvesting, aquatic environment size, and standcharacteristics. These factors drive wind exposure, speed, and force, which determine post-harvestwindthrow risk. Furthermore, windthrow negatively affected the water quality index of the adjacentaquatic systems, i.e., greater windthrow decreased the protective effect of the riparian buffer. Werecommend increasing the use of partial harvest near riparian environments and adapting riparianbuffers to site conditions to ensure the long-term protection of adjacent freshwater ecosystems.
