4 Lake Simcoe Natural Heritage Estate Natural Heritage Area Designation Management Authority Total Number of Areas Provincial Parks Ontario Parks 6 Conservation Areas Areas of Natural and Scientific Interest Candidate Areas of natural and Scientific Interest Private Lands and Waters Lake Simcoe Conservation Authority Lakes Simcoe Conservation Authority and Ministry of Natural Resources Various (e.g., Nature Conservancy of Canada) Total 137 Total Area (Ha) and % of Watershed (0.21%) (0.28%) 12,016.8 (3.64%) 5,607.6 (1.70) 3,373.0 (1.02) 22,614.6 (6.85%)

5 Methods 1. Using GCMS, provide a general sense of the changes in climate projected for several natural heritage areas in the Lake Simcoe Watershed. 2. Use tree species distribution as a proxy to deduce potential representation change in Lake Simcoe watershed natural heritage areas.

11 Consequences Changes in the representation of terrestrial life science, aquatic life science, and earth science features within natural heritage areas. Increased frequency and scale of disturbances such as insect outbreaks; increased frequency and scale of extreme events such as flooding, drought, and wind; and an increase in the distribution and abundance of terrestrial and aquatic invasive species could affect the ecological integrity (ecological health) of natural heritage areas within the Lake Simcoe Watershed. Need to adapt active management objectives within Watershed natural heritage areas (i.e., objectives associated with ecological/shoreline restoration).

12 Nature-based Tourism & Recreation Natural assets are used by residents, draw hundreds of thousands of visitors every year, and generate millions of dollars for the provincial and local economies. Demand for recreational opportunities will continue to grow. Climate change presents a number of important challenges to planners and managers responsible for the provision of nature-based tourism and recreational opportunities.

14 Methods Assessed tourism and recreation vulnerability to climate change in the Lake Simcoe Watershed: 1. Length of the ice fishing season 2. Length of the snowmobiling season 3. Park visitation patterns

15 Ice Fishing Winter of 1997/98 was the warmest on record in the Great Lakes region (+3.7 C above normal) Lake Simcoe ice fishing season during this winter was on average 52% shorter than the winter of 2000/01 Mean min temperature for was C 2020s: 2.5 C, 2050s: 5.3 C, 2080s: 7.4 C warmer than mean min temp in coldest month

17 Consequences Climate change-induced changes to ecosystem composition, structure, and function could affect visitor attractions, visitation patterns, the provision of recreational activities and the overall quality of the recreational experience. Need to determine how to manage for climate changeinduced visitor behavioral responses and shifting (and emerging) destination and recreational preferences. Need to ensure visitor safety.

20 Overview of Policy Delphi Process Iterative group-oriented Idea Generating Strategy (IGS) that seeks to generate the strongest possible opposing views on the potential resolutions of a major policy issue Participants are afforded the freedom to present and challenge alternative viewpoints, and to think reflectively and independently between iterations

21 Advantages Overcomes limitations of other IGSs, including: one or a few vocal individuals to dominate the discussion people to remain silent, possibly due to shyness or fear of censure the rut effect (i.e., participants getting hung-up on one thought and staying in that rut for the duration of the meeting) the power of persuasion and the bandwagon effect the unwillingness to abandon norms geographic isolation cost

22 What s Required from You? Commitment to the process Today is just the beginning Two rounds will follow

23 Guiding Statement Based on the information that has been presented to you and what you know personally about projected climate change impacts for this theme, please identify any adaptation measures that would reduce or eliminate negative impacts or exploit potential beneficial opportunities.

24 Examples of Questions 1) Increasing Knowledge What types of information and forms of knowledge are required to support robust and flexible decision-making? 2) Strategic Planning What short- and long-term strategic planning is required to support the vision of the Lake Simcoe Protection Plan? 3) Legislation and Policy What types of policies are required to provide for an adaptive approach to decision-making?

25 Examples of Questions 4) Knowledge Dissemination What types of communication tools and techniques are needed to: 1) enhance public understanding of the climate change impact and (potential) management actions; and, 2) enhance education, extension, and training opportunities within management agencies? 5) Planning and Management What types of land-use planning and adaptive management frameworks are required to mitigate negative impacts and exploit beneficial opportunities associated with known and potential consequences on cultural, social, economic, and ecological systems?

26 The End Thank You!
