Manitoba contains over 22 million hectares of wetlands, and Manitoba Hydro is growing its 12,000 km of transmission system to meet growing energy demands. In efforts to minimize its effects on wetlands and recognize the role they play in the environment, Manitoba Hydro has incorporated consideration for wetlands as a key criterion in its route selection process. With over-abundant wetlands, avoidance is not always possible, to address any potential effects when working in wetlands, Manitoba Hydro implements standard mitigation practices during construction and operations. To better understand the effects of new transmission line development on wetlands, monitoring of ground disturbance, vegetation species abundance and composition, along with wildlife species that consider wetlands their home is ongoing. Manitoba Hydro continues to take a multi-pronged approach to mitigate project effects on wetlands but appreciates the need to advance the development of best management practices for a consistent scientifically-based approach to effective wetland protection.
