These Principles and Guidelines for Ecological Restoration in Canada’s Protected Natural Areas represent the first-ever Canada-wide guidance for ecological restoration practices. They result from collaboration among experts and managers from Canada’s federal, provincial and territorial parks and protected areas agencies, Canadian and international universities, the US National Park Service, the Society for Ecological Restoration International (SER), and SER’s Indigenous Peoples Restoration Network Working Group. These principles and guidelines describe an approach to restoration that will ensure that parks and protected areas continue to safeguard ecological integrity while providing opportunities for meaningful engagement and experiences that connect the public, communities, and visitors to these special places and help ensure their relevance into the future. They constitute an important tool for making consistent, credible and informed decisions regarding the management of issues of common concern to parks and protected areas agencies in Canada and internationally.
