Preface

The Canadian Councils of Resource Ministers developed a Biodiversity Outcomes FrameworkReference 1 in 2006 to focus conservation and restoration actions under the Canadian Biodiversity Strategy.Reference 2 Canadian Biodiversity: Ecosystem Status and Trends 2010Reference 3 was the first report under this framework. It presents 22 key findings that emerged from synthesis and analysis of background technical reports prepared on the status and trends for many cross-cutting national themes (the Technical Thematic Report Series) and for individual terrestrial and marine ecozones+ of Canada (the Ecozone+ Status and Trends Assessment Report Series). More than 500 experts participated in data analysis, writing, and review of these foundation documents. Summary reports were also prepared for each terrestrial ecozone+ to present the ecozone+-specific evidence related to each of the 22 national key findings (the Evidence for Key Findings Summary Report Series). Together, the full complement of these products constitutes the 2010 Ecosystem Status and Trends Report (ESTR).

This report, Mixedwood Plains Ecozone+ Evidence for Key Findings Summary, presents evidence from the Mixedwood Plains Ecozone+related to the 22 national key findings and highlights important trends specific to this ecozone+. It is based on the Mixedwood Plains Ecozone+ Status and Trends Assessment--with an emphasis on Ontario,Reference 4 as well as further synthesis done to specifically address the national key findings. Additional information was provided by the Quebec Region of Environment Canada. The report is not a comprehensive assessment of all ecosystem-related information. The level of detail presented on each key finding varies and important issues or datasets may have been missed. As in all ESTR products, the time frames over which trends are assessed vary--both because time frames that are meaningful for these diverse aspects of ecosystems vary and because the assessment is based on the best available information, which is over a range of time periods. Many experts from a broad range of disciplines, including university researchers, government scientists, and renewable resource and wildlife  managers, contributed to the technical report as authors and reviewers (see Acknowledgements section). This key finding summary report was also reviewed by federal and territorial government scientists and managers and, in part or as a whole, by several university researchers.

Ecological classification system – ecozones+

A slightly modified version of the Terrestrial Ecozones of Canada, described in the National Ecological Framework for Canada,Reference 5 provided the ecosystem-based units for all reports related to this project. Modifications from the original framework include: adjustments to terrestrial boundaries to reflect improvements from ground-truthing exercises; the combination of three Arctic ecozones into one; the use of two ecoprovinces--Western Interior Basin and Newfoundland Boreal; the addition of nine marine ecosystem-based units; and, the addition of the Great Lakes as a unit. This modified classification system is referred to as "ecozones+" throughout these reports to avoid confusion with the more familiar "ecozones" of the original framework.Reference 6 The boundary for the Atlantic Maritime is the same in both frameworks.

Long Description for map of the ecozones

This map of Canada shows the ecological classification framework for the Ecosystem Status and Trends Report, named “ecozones+”. This map shows the distribution of 15 terrestrial ecozones+ (Atlantic Maritime; Newfoundland Boreal; Taiga Shield; Mixedwood Plains; Boreal Shield; Hudson Plains; Prairies; Boreal Plains; Montane Cordillera; Western Interior Basin; Pacific Maritime; Boreal Cordillera; Taiga Cordillera; Taiga Plains; Arctic), two large lake ecozones+ (Great Lakes; Lake Winnipeg), and nine marine ecozones+ (North Coast and Hecate Strait; West Coast Vancouver Island; Strait of Georgia; Gulf of Maine and Scotian Shelf; Estuary and Gulf of St. Lawrence; Newfoundland and Labrador Shelves; Hudson Bay, James Bay and Fox Basin; Canadian Arctic Archipelago; Beaufort Sea).

Content for this report for the Ontario portion of the ecozone+ is drawn heavily from Mixedwood Plains Ecozone+ Status and Trends Assessment--with an emphasis on Ontario.Reference 4 Specialists from the Ministère des Ressources naturelles  et Faune du Québec as well as Environment Canada and Agricultural and Agri-Food Canada contributed to several key findings as both authors and reviewers extending the coverage beyond Ontario for those key findings. Reviews of versions of this summary report were provided by scientists and resource managers from relevant provincial and federal government agencies.

Long description for Figure 1

This map provides an overview of the Mixedwood Plains Ecozone+, which is located in the provinces of Ontario and Quebec south of the Precambrian Shield. It is bordered along the south and west by Lake Ontario, Lake Erie, Lake St. Clair, the state of Michigan, and Lake Huron and along the southeast by the states of New York and Vermont and the province of Quebec. Majors cities located within the ecozone+, from west to east, are Windsor, Port Franks, London, Brantford, Hamilton, Toronto, Niagara Falls, Ottawa, Montreal and the city of Quebec. Major lakes and rivers in the ecozone+ are, from west to east, the Thames River, Lake Simcoe, Kawartha Lakes, the Ottawa River, the St. Lawrence River, the Richelieu River and Lac Saint-Pierre. Manitoulin Island, in Lake Huron, is also located within the Mixedwood Plains Ecozone+
