Natural wetlands provide many ecosystem services essential to wildlife and valued by humans. However, global declines in natural wetlands due to land-use change means that artificial wetland construction and restoration efforts are becoming increasingly important.
Our research partner, Ducks Unlimited Canada, monitors and manages many wetland ecosystems in the Cumberland Marsh Region (CMR), along the border of NB and NS, maritime Canada. Anecdotal observations by wetland mangers and some scientific study suggests that artificial wetlands in the CMR show signs of declining aquatic productivity several years after construction.
Strategic sampling of aquatic macroinvertebrates, combined with other environmental measures, will allow investigation of dozens of artificial wetlands believed to show recent productivity declines. Collaboration with our research partners will allow us to better understand senescence and developed monitoring techniques exportable to other wetland restoration initiatives in Atlantic Canada.
