Anthropogenic and Environmental Stressors in Cook Inlet Beluga Whales, Literature Review and Assessment

September 01, 2011

Information about anthropogenic and select environmental factors that are believed to have a potentially negative impact on the Cook Inlet, Alaska.

At reduced numbers and with contraction of their range, this population is far more vulnerable to losses due to nonlethal anthropogenic stressors than it was at a population level similar to the 1300 belugas seen in the 1970s. Disturbances that cause belugas to temporarily or permanently abandon summer feeding and calving areas could reduce their ability to reproduce or survive through the winter months.
