Master of Science in Ecological Restoration Applied Research Projects

Description

This is Canada’s first master’s program specializing in Ecological Restoration and is offered as a joint program between British Columbia Institute of Technology (BCIT) and Simon Fraser University (SFU). The MSc in Ecological Restoration combines the strong technical and applied (experiential) knowledge at BCIT with SFU’s fundamental (contextual) basic science and community engagement expertise.

Throwing shade
Reed canarygrass (Phalaris arundinacea) is an invasive grass common in wetlands and riparian areas throughout the Pacific Northwest. It is highly adaptable and resistant to many control methods, but is vulnerable to shading. We sought to control reed canarygrass by establishing desirable native shrubs to overtop and shade it. Plots were rototilled, mulched, live-staked, and monitored for 2-6 growing seasons. We tested 1) effective planting densities by live-staking hardhack (Spiraea douglasii) at 50, 30, and 15 cm spacing, 2) relative species performance by planting hardhack, red-osier dogwood (Cornus sericea), and thimbleberry (Rubus parviflorus), all at 30 cm densities, and 3) alternative site preparation methods by using cardboard mulch or excavating the top 20 cm of topsoil. Higher planting density significantly reduced reed canarygrass cover and biomass. Both hardhack and red-osier dogwood successfully suppressed reed canarygrass, though thimbleberry did not. No significant differences between site preparation methods were observed., reed canarygrass, Phalaris arundinacea, invasive species management, live staking, planting density, Spiraea douglasii
