All Rivers Institute courses are delivered through the Ecological Restoration Program.
This course covers the fundamentals of wetland and estuary form, function, classification and restoration in Canada. The wetland section of the course covers wetland classification, examines mechanisms of wetland loss and the importance of wetlands in storing carbon, and the physical, chemical and biological mechanisms by which constructed wetlands remove pollutants from urban storm water. The steps for building groundwater wetlands, surface water wetlands, wetlands with liners and floating wetland will be examined, in addition to the steps for building and maintaining constructed wetlands. The estuary section of the course covers estuary classification, reviews the high ecological importance of estuaries and reviews the physical, chemical and biological nature of estuaries. Procedures for restoring estuaries is covered, including dealing with invasive species, legacy contaminants and non-migratory Canada geese. The course will focus on re-establishing the carbon flux and storage in in the estuaries through re-planting of sub tidal eelgrass, emergent sedges and strategic placement of large woody debris.
Students will participate in a weekend field trip to design a wetland for construction the following year, construct a wetland, or monitor the performance of a recently constructed wetland.
This course will give a detailed overview of freshwater restoration techniques used primarily to mitigate losses of salmonid habitat and stocks. The spectrum will examine physical, chemical, thermal, and biological restoration technologies used in this province, some of which are new and innovative, while others have been used extensively over the last 100 years. Aspects of this course will include; spawning channels, fish ladders, development of off-channel habitats, in-stream woody debris placement, lake fertilization, stream fertilization, hypolimnetic cold-water withdrawal, mitigation of Total Gas Pressure (TGP) supersaturation at dams, lake destratification, hypolimnetic aeration/oxygenation, fish passage and culvert re-design, and biomanipulation.
Students will require a laptop and access to the internet to complete some in-class assignments.
