Effects of forest harvesting and fire on fish assemblages in Boreal Plains lakes: A reference condition approach
Download2003
Scrimgeour, G.J., Lange, M., Prepas, E.E., Westcott, K., Aku, P.K.M., Paszkowski, C.A., Tonn, W.M.
To assess the impacts of forest harvesting and fires on lentic fish assemblages in the Boreal Plains ecoregion (Alberta, Canada), we applied a reference condition approach to 37 lakes in burned, logged, or undisturbed catchments. Fish assemblages in the reference lakes were classified into two...
