Preface

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 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, Atlantic Maritime Ecozone+ Evidence for Key Findings Summary, presents evidence from the Atlantic Maritime Ecozone+ Status and Trends AssessmentFootnote4 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. Also, because of the report’s timing or a lack of readily available ecozone+-specific information, some key findings were not addressed. 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 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+, two large lake ecozones+, and nine marine ecozones+.

Long Description for Figure 1

This map of the Atlantic Maritime ecozone+ shows the location of cities/towns and bodies of water which are referred to within this report. This ecozone+ is located on the southern Atlantic coastline of Canada and fully encompasses the three Canadian Maritime provinces of New Brunswick, Nova Scotia, and Prince Edward Island as well as a portion of southern Quebec. The area of Quebec included in this ecozone+ encompasses the Gaspé Peninsula, Îles-de-la-Madeleine, part of the eastern shore of the St. Lawrence River, and includes the cities of Gaspé, Rimouski, and Sherbrooke but not Québec City. Its southern boundary is defined by the Canada–U.S. border.
