The Species

The white whales of Cook Inlet.

Cook Inlet belugas are a genetically distinct population isolated for over 10,000 years. They are the only belugas that live year-round in the shadow of a major American city.

Compounding Threats

Noise Pollution

Ship traffic and seismic surveys disrupt echolocation and foraging.

Prey Availability

Salmon and eulachon runs are critical to summer feeding success.

Habitat Loss

Industrial development along Knik and Turnagain Arms reduces usable range.

Strandings

Extreme tides and mudflats make Cook Inlet uniquely hazardous.

Recovery Efforts

A federal recovery plan, locally executed.

NOAA Fisheries finalized the Cook Inlet beluga recovery plan in 2016. The Beluga Whale Alliance contributes the citizen science backbone — shore observations, photo-ID matching, and outreach that no federal budget could fund alone.
