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 2010 Reference 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 Technical Ecozone+ Reports). 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, Hudson Plains Ecozone+ Evidence for Key Findings Summary, presents evidence from the Hudson Plains Ecozone+ related to the 22 national key findings. The report is not a comprehensive assessment of all ecosystem-related information. The level of detail presented on each key finding varies, and issues or datasets may have been missed. Some emphasis is also placed on information from the national Technical Thematic Report Series. 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.

This summary report is based on the full Technical Ecozone+ Report for this ecozone+, Hudson Plains Ecozone+ Status and Trends Assessment, Reference 4 which was prepared for this project and also incorporates information from many of the Technical Thematic Reports. Many experts from a broad range of disciplines and organizations contributed to the full Hudson Plains status and trends assessment as authors and reviewers (see acknowledgements section on page iii). Additional reviews of this summary report were provided by scientists and resource managers from relevant provincial, territorial, and federal government agencies.

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 For the Hudson Plains, modifications were made to the southern boundary of the ecozone within Ontario to reflect the actual contact between the Precambrian and Paleozoic bedrock.

Ecological classification system – ecozones+
This map of Canada shows the ecological classification framework
Long description for Preface Figure

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).

Long description for Figure 1

This map of the Hudson Plains Ecozone+ shows the locations of cities/towns and bodies of water which are referred to within this report. This ecozone+ runs from the eastern corner of Manitoba, along the Hudson Bay into Ontario, to the eastern side of the James Bay in Quebec and includes Akimiski Island, Nunavut. Cities/towns shown are: Churchill, Gillam, York Factory, and Shamattawa in Manitoba (Gillam lies outside of ecozone+ boundaries, but is shown for geographic context), Fort Severn, Peawanuck, Cape Henrietta Maria, Attawapiskat, Kashechewan, Fort Albany, Moosonee, and Moose Factory in Ontario, Waskaganish, and Eastmain in Quebec. From west to east, the labeled rivers are: Churchill, Nelson, Hayes, Severn, Winisk, Sutton, Attawapiskat, Albany, Moose, Harricana, Nottaway, Rupert, and Eastmain. Missisa Lake is west of Fort Albany. Further details can be found in the preceding/next paragraph(s).
