The Canadian Councils of Resource Ministers developed a Biodiversity Outcomes Framew orkFootnote1 in 2006 to focus conservation and restoration actions under the Canadian Biodiversity Strategy.Footnote2 Canadian Biodiversity: Ecosystem Status and Trends 2010Footnote3 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 Ecozones+ 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 ecozones+ to present the ecozones+-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, Prairies Ecozones+ Evidence for Key Findings Summary, presents evidence from the Prairies Ecozones+ Status and Trends AssessmentFootnote4 related to the 22 national key findings and highlights important trends specific to this ecozones+. 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. Although this is intended to be a comprehensive analysis, some issues may require further exploration. 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 Canada,Footnote5 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.Footnote6 The boundary for the Prairies is the same in both frameworks.
The ESTR Secretariat acknowledges Trish Hayes, Melanie Dubois (Agriculture and Agri-Food Canada), and Jeff Thorpe (Saskachewan Research Council) for the preparation of various drafts of the report. This report was overseen and edited by Trish Hayes and Patrick Lilley. Kelly Badger was the lead graphics designer. Additional support was provided by Jodi Frisk, Ellorie McKnight, Michelle Connolly, and others. It is based on the draft Prairies Ecozone+ Status and Trends Assessment.4 Other experts made significant contributions to that draft report and are listed below. Reviews were provided by scientists and resource managers from relevant provincial/territorial and federal government agencies. The Canadian Society of Ecology and Evolution also coordinated reviews with external experts.
