The Canadian Councils of Resource Ministers developed a Biodiversity Outcomes FrameworkFootnote1 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 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, Arctic Ecozone+ Highlights and Key Findings Summary, differs from the other summaries. It consists of two parts. The first part presents highlights from the full Arctic Ecozone+ status and trends assessment, providing an overview of the ESTR findings for the Arctic and providing a foundation for further work on ecological indicators and ecological assessment. The second part presents a table that summarizes the evidence from the Arctic Ecozone+ related to the 22 national key findings. The full technical assessment for the Arctic should be consulted for further information and discussion of ecological context, and for source references. Note that the technical report was updated from a 2010 draft, and it is based partly on the national thematic trend analyses. The time span of all trends presented is specified; in some cases more recent data may be available.
The Arctic component of ESTR covers Canada’s terrestrial and freshwater Arctic ecosystems, essentially the landmass north of treeline (referred to as the Arctic Ecozone+). Jurisdictions within the Arctic Ecozone+ are all of Nunavut and northern Northwest Territories, Yukon, Quebec, and Newfoundland and Labrador. This is the homeland of Canadian Inuit.
Ecological classification system – ecozones+
A slightly modified version of the Terrestrial Ecozones of Canada, described in the National Ecological Framework for CanadaFootnote4, 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.Footnote5
This report was written and designed by Joan Eamer, with editing and review by Patrick Lilley of the ESTR Secretariat. This report is based on the Arctic Ecozone+ Status and Trends Assessment. Acknowledgements for that assessment are listed below.

Review conducted by scientists and renewable resource and wildlife managers from relevant territorial and federal government agencies through a review process recommended by the ESTR Steering Committee. Additional reviews of specific sections conducted by university researchers in their field of expertise at the request of the authors. Peer review of the final draft coordinated by the Canadian Society for Ecology and Evolution. The report was greatly improved by the reviews of D. Berteaux, P. Hale, and one anonymous reviewer.
