The purpose of Bird Conservation Regions strategies is to summarize the important issues and to recommend the actions required to conserve populations of birds in Canada. The Bird Conservation Regions (BCR) used as the basis for our planning units are based on the Commission for Environmental Cooperation’s internationally-accepted Level III ecoregions. We have adopted Marine Biogeographic Units as the planning units for marine birds. The data presented here have three main functions: to provide a consistent national approach to planning for bird conservation in Canada; to streamline the planning process; and to provide sufficient guidance to allow the development of detailed implementation plans and to support on-the-ground conservation efforts.

The Canadian Wildlife Service - Ontario Region Biodiversity Atlas represents the Canadian Wildlife Service biodiversity portfolio across the Ontario portions of the Boreal Hardwood Shield (Bird Conservation Region 12) and Mixedwood Plains (Bird Conservation Region 13) ecozones. These data are the derived product from an extensive landscape assessment that assessed the Canadian Wildlife Service biodiversity portfolio (Species at Risk, migratory birds, habitat) at various resolutions. Biodiversity is mapped by forest, grassland (open country) and wetland quality and quantity, and then progressively combined to identify local High Value Biodiversity Areas. At the finest resolution, scores were applied to each unit of analysis (5 hectare hexagon in Bird Conservation Region 12; 2 hectare hexagon in Bird Conservation Region 13), based on over 30 criteria for landscape habitat condition, Species at Risk and migratory birds.

Population trend estimates based on data collected through the North American Breeding Bird Survey (BBS), for approximately 300 Canadian bird species. The trend results are Canadian trends and thus use data from Canadian BBS routes only. Results are updated annually; these estimates use BBS data from 1970 through 2009. Trends are presented for species, provinces, territories, and Bird Conservation Regions (BCR) for which there are sufficient BBS data for statistical analysis.The estimates were generated using a maximum likelihood, annual index analysis, which differs from the analysis currently used to generate trend and annual index estimates.

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Population status of Canada's migratory birds indicator reports the proportion of bird species listed in the Migratory Birds Convention Act whose populations fall within, or are above or below national population goals. It provides a snapshot assessment of the state of bird populations in Canada. Some bird species are managed towards specific population levels (for example, some hunted species or species of conservation concern).

Archived population trend estimates, based on data collected through the North American Breeding Bird Survey (BBS), for approximately 300 Canadian bird species. These archived estimates use data from Canadian BBS routes only, collected from 1970 through 2011. Trends are presented for species, provinces, territories, Bird Conservation Regions (BCR), as well as the sub-regions that make up the analytical strata (intersections of BCRs and provinces/territories), for which there are sufficient BBS data for statistical analysis. These estimates were produced using a hierarchical Bayesian model, which differs from the maximum likelihood model that was used to generate BBS trend estimates from 2002 through 2009.
