Data Sources and Methods: General Status of Species Indicator

Data

3.1 Data source

Data for the General status of species indicator are drawn from the Wild Species reports (CESCC 2001; CESCC 2006; CESCC 2011).

Data contributing to the assessment of individual wildlife species in the Wild Species reports are drawn from a wide range of sources and are cited within the relevant reports.

3.2 Spatial coverage

Species are assessed throughout Canada at the regional level (in all provinces, territories and ocean regions) and at the national level.

3.3 Temporal coverage

The status of wild species is generally reassessed by the Canadian Endangered Species Conservation Council (CESCC) every five years. The first assessment was done in 2000 for 1670 species (CESCC 2001). New species groups were added in subsequent reports and in 2005, 7732 species were assessed (CESCC 2006). In 2010, 11 950 species were assessed and fish species were not reassessed (CESCC 2011).

3.4 Data completeness

The General status of species indicator covers only the suite of wildlife species assessed in the Wild Species 2010 report (CESCC 2011). Knowledge regarding wild species varies among regions and among taxonomic groups. A risk ranking was attributed only to species that have sufficient data to be assessed. Fish species were not reassessed in 2010.

3.5 Data timeliness

The general status of species is assessed every five years; this indicator is current to the end of 2010.
