2 Provides an assessment of the estimated viability or probability of persistence of the population (see Appendix C).

3 Following a review of the data by the CDPNQ in 2011, individuals from the Pointe du Gouvernement and Marcel-Raymond Ecological Reserve are considered to be part of the same population. No individuals have been detected in the Pointe du Gouvernement sector since 1992 and no individuals have been transplanted there.
