Scientists map recovery for endangered orcas off British Columbia’s coast
BRITISH COLUMBIA, CANADA, JUL 7 – The strategy aims to prevent extinction of southern resident orcas using innovative conservation methods, addressing urgent risks faced by this population, researchers said.
- A report published on July 7, 2025, reveals that the critically endangered southern resident killer whales off British Columbia and Washington show no signs of recovery.
- The report follows a March workshop of 31 experts from Canada, the U.S., and Europe, and notes that limited access to chinook salmon remains the main barrier to recovery.
- It recommends 26 science-based actions including fisheries restrictions, underwater noise standards, expanded ship slowdown zones, and prohibiting wastewater discharge near whale habitats.
- The Fisheries Department identified the whales as a highly threatened and emblematic population, with only 73 remaining according to the latest census, and stated that Ottawa plans to implement gradual actions rather than issuing an immediate emergency protection order.
- The report’s findings and government decisions imply recovery will require sustained strong efforts and time, as these long-lived whales reproduce slowly and face imminent survival threats.

A Public Dataset of Annotated Orcinus orca Acoustic Signals for Detection and Ecotype Classification
Killer whales (Orcinus orca) exhibit significant ecological and genetic diversity, with three primary sympatric populations in the Northeast Pacific: Resident, Bigg’s (Transient), and Offshore. Each population is characterized by distinct foraging habits, social structures, and vocal repertoires, which complicate accurate monitoring and conservation efforts. This dataset, compiled from diverse sources, provides a comprehensive resource for the d…
