Data contributing to the assessment of individual wildlife species are drawn from a wide range of sources, which are cited within the relevant status reports.

The indicator is national.

3.5 Data timeliness
The Committee meets twice per year to consider recent species reports, assess wildlife species' risk of extinction or extirpation, and designate a status category. Individual species are generally reassessed every 10 years. This indicator is current to May 2016.
