Certain species considered provincially rare in the Lake Simcoe watershed including some listed as threatened or endangered under Ontario's Endangered Species Act (Statutes of Ontario 2007), may be at risk of extirpation due to adverse effects of natural and/or anthropogenic stressors. Climate change, acting alone or in combination with other stressors, may pose an important emerging threat for many of these species. Several tools to assess climate change effects are being developed for use by resource managers to categorize the relative vulnerability of selected species to climate change. In response to the Lake Simcoe Protection Plan, Ontario's Adaptation Strategy and Action Plan: 2011-2014, and the Ministry of Natural Resources' Climate Change Strategy, vulnerability assessments have been completed for selected natural assests in the Lake Simcoe watershed. By testing the model against a subset of high priority provincially rare species found within the Lake Simcoe watershed the authors objectives were to: categorize the relative vulnerability of each species; identify species-level indicators that are useful for assessing vulnerability to climate change; identify the key factors causing species vulnerability.--Document.

In this report, the authors document the development and application of a vulnerability assessment that can be used with other tools and techniques to assess wildlife vulnerabilities to climate change and inform an adaptive strategic planning process. The authors selected four wildlife indicators to assess the ecological condition of the Lake Simcoe Watershed and to identify potential vulnerabilities to climate change and land use practices. The four indicators are avian guild species richness, anuran calling and breeding phenology, mammal species richness, and landscape fragmentation. These indicators were selected because they describe local biodiversity, community and range boundary dynamics, population size, and landscape fragmentation all of which are affected by or interact with climate to influence wildlife populations.--Document.

On- strategies organized according to the need to understand climate site land use planning and management techniques must be change, mitigate the impacts of rapid climate change, and help designed to protect the ecological and social pieces, patterns, Ontarians adapt to climate change: and processes. [...] Given the uncertainty in the amount of emissions and associated effects, natural resource management agencies around the world are using a number of climate models and scenarios of human behaviour to depict a range of potential climatic conditions and impacts that may appear in the next 100 years. [...] It is notable that the countries attending the 2005 climate change conference in Montreal to review and discuss future programs under the auspices of the United Nations Framework Convention on Climate Change and the Kyoto Protocol agreed that the development of adaptation tools and techniques should receive significant attention during the next 5 years. [...] Species Distribution and Abundance in Response to Climate Change The distribution and abundance of a species across its geographic range is related to both biotic (e.g., food, competition, and disease) and abiotic (e.g., climate and substrate) factors. [...] There are several ways to examine the effects of climate on terrestrial fauna, and to determine how climate change may affect species and their habitat in the future.

The authors assessed the vulnerability of furbearers in the Clay Belt to climate change. They identified four processes leading to vulnerability: the introduction of southern competitors and pathogens, increased extinction risk of cold-adapted species, selection for early breeding, and reduced synchrony. Potential indicators of these processes include the distribution and abundance of temperate species, such as the raccoon (Procyon lotor) and the distribution and abundance of cold-adapted species, such as the American marten (Martes americana) and Canada lynx (Lynx canadensis). Other indicators include changes in the seasonal timing of breeding in rodents such as the muskrat (Ondatra zibethicus) and changes to the frequency and amplitude of the lynx-snowshoe hare (Lepus americanus) cycle. Overall, they anticipate that climate change will result in the Clay Belt and its constituent furbearer species becoming more temperate in character.--Document.
