On the Persistence of Cyanobacteria in Lakes in BC

In my talk I will be discussing the issue of persistent blue-green algae blooms in the lakes of Southwestern British Columbia. Quamichan and Somenos Lakes will be used as models to illustrate the pathology of systems that have become dominated by blue-green algae.  I will describe how historic and current land management has combined with anthropogenic phosphorus to create persistent blue-green algae blooms in urban and rural lakes across southwest BC and, indeed, much of the industrialised world. I will describe monitoring and research that is being done in the Cowichan Valley and Victoria area to understand the issue and the management options that are available for controlling blue-green algae in our lakes.
