Land Use impacts on nutrients dynamics and primary production in streams

In Progress:  "1. Analysis of relationships between periphyton growth and nutrients  for northern rivers in Alberta, as part of NREI.  2. Analysis of  relationships between aquatic plant growth and nutrients for streams  in the St. Lawrence Lowlands, as part of Great Lakes.  3. Analysis of  data on the effects of forest fire and timber harvest on western  boreal steams, as part of joint program with University of Alberta  funded by NSERC and AlPac (Alberta Pacific Forestry Products Inc.)    Goals and objectives - Nutrient (N and P) loading from point and  non-point sources affects the chemistry and biological communities of  receiving waters.  Impacts include accelerated eutrophication of  surface waters resulting in loss of habitat, changes in biodiversity,  and loss of recreational potential.  - The aim of this study is to  evaluate the impacts of nutrient loading from non-point sources  (agriculture and forestry) and point sources (municipal wastewater  discharge, industrial inputs) on nutrient dynamics and primary  production in streams and rivers. - This study will quantify the  impacts of nutrients on aquatic plant growth in flowing waters,  develop an approach for setting nutrient guidelines, and provide  recommendations for nutrient guidelines in key ecoregions of Canada  (the western boreal forest of Alberta and the St. Lawrence Lowlands of  Ontario/Quebec.  - This work contributes to the NREI and the Great  Lakes Action Plan.
