Regional/Continental
1% of the regional/continental population estimate.
Sub-regional/National SAR
The sub-regional/national SAR threshold = 1% of the COSEWIC population estimate for the region (provinces/territories) in which the species is listed as being at risk. This threshold is used to identify trigger species and IBAs under criterion C1.
