Preface

The Canadian Councils of Resource Ministers developed a Biodiversity Outcomes FrameworkReference 4 in 2006 to focus conservation and restoration actions under the Canadian Biodiversity Strategy.Reference 7 Canadian Biodiversity: Ecosystem Status and Trends 2010Reference 8 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 Assessments). 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, Boreal Plains Ecozone+ Evidence for Key Findings Summary, presents evidence from the Boreal Plains Ecozone+ related to the 22 national key findings and highlights important trends specific to this ecozone+. It 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. Some emphasis has been 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.

Ecological classification system – ecozones+

A slightly modified version of the Terrestrial Ecozones of Canada, described in the National Ecological Framework for CanadaReference 9 , 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 10

Ecological classification system – ecozones+
Map
Long description for Ecological classification system – 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).

Overview Map of Boreal Plains Ecozone+
Long description for Figure 1

This map shows the location of cities/towns and bodies of water referred to in this report. The ecozone+ encompasses a section of southern Manitoba, central Saskatchewan, central Alberta, and small section of northeastern British Columbia (British Columbia). Towns in British Columbia include Fort Saint John and Dawson Creek. In Alberta, the Peace River and Lake Athabasca delineate the northernmost section of the ecozone+. The southern edge of the boundary within Alberta runs just north of Grande Cache, Calgary and Edmonton. Whitecourt, Lesser Slave Lake, the Athabasca River, the Athabasca Oil Sands, and Fort McMurray fall within the ecozone+. The ecozone+ runs across central Saskatchewan north of Saskatoon, Regina, and Whitewood and includes the Saskatchewan River and the Porcupine Hills. In Manitoba, Lake Winnipegosis, the majority of Lake Manitoba, and Lake Winnipeg are located within the ecozone+. Selkirk is within the ecozone+ but the city of Winnipeg is not.
