Population viability analysis of the Southern Resident Killer Whales
Submitted by: Raincoast Conservation Foundation
- The Southern Resident Killer Whale population cannot withstand additional negative pressures.
- The project’s approval would create additional threats to the population’s survival, and the probability of the Southern Resident Killer Whale population dropping below 30 individuals (a “quasi-extinction”), is “unacceptably high” when considering new threats added by project’s approval.
- A model created by authors shows a greater than a 50% chance of the population declining below 30 individuals within the next 100 years when the cumulative negative effects of the project are taken into account.
