Towards Climate Change Adaptation in Canada's Protected Natural Areas: an Ontario Parks Case Study

Climate is a major catalyst of change in the composition, structure and function of the Ecosphere. Empirical studies of species response to climate consistently reveal that the anomalous warming occurring over roughly the past half-century is having a discernible impact on contemporary biodiversity. Climate change has also been implicated in several species extinctions, a phenomenon projected to be exacerbated in the future. These studies and events indicate that the implications of climate change for biodiversity conservation are considerable. Biodiversity conservation is one of the major modern rationales behind formal protected natural areas establishment, planning and management. However, most protected natural areas have been designed to protect in perpetuity specific natural features, species and communities in-situ, and don’t take into account shifts in ecosystem composition, structure and function that are being induced by climatic change. The ecological manifestations of climate change will be such that the established species management objectives of some protected natural areas will no longer be viable. Consequently, protected natural areas agencies will need to be adaptive in order to be able to respond to climate change-induced impacts and improve their ability to deliver their various protected natural area- and biodiversity-related mandates, such as the perpetual protection of representative elements of natural heritage. The principal goal of this dissertation was to begin the process of climate change adaptation (mainstreaming) within the Canadian protected natural areas community, thereby facilitating the ability of jurisdictions, agencies and organizations to adapt to climate change-related impacts and implement adaptation decisions. To realize this goal, four objectives were formulated: i) to synthesize the state of knowledge on climate change, biodiversity and protected natural areas policy, planning and management; ii) to establish the state of climate change adaptation with respect to Canadian protected natural areas agencies; iii) to assess the current position, priorities, and challenges of, and barriers to, Canadian protected natural areas agencies with respect to climate change adaptation; and iv) to develop a climate change adaptation portfolio and evaluate the suitability of the portfolio for implementation by a Canadian protected natural areas agency, Ontario Parks. The research revealed that while mainstreaming climate change
