October 3, 2023 — The number of southern resident orcas that forage along the Oregon Coast has been on the decline for decades as they struggle to find food and confront boats and pollution.
Just 73 are left, down from a peak of nearly 100 in the late 1990s. Officials from the National Oceanic and Atmospheric Administration’s fisheries division project the number could decline by half during the next 20 years.
Now, the state’s Fish and Wildlife Commission will weigh whether to add the orcas to the state’s endangered species list, creating more protections for the orcas and directing more conservation money toward their survival. The Oregon Department of Fish and Wildlife on Thursday produced an assessment of the situation that the commission will review. Southern resident orcas are already listed as endangered under the federal Endangered Species Act and in Washington and Canada, where they also live and forage. Being listed under Oregon’s Endangered Species Act would offer even greater protections, according to Miyoko Sakashita, oceans program director for the nonprofit Center for Biological Diversity.
“While the federal listing is helpful, some of its provisions only apply to federal actions,” Sakashita said via email. “By having a state listing, the state has more powerful tools to address threats to orcas and their salmon prey.”
If listed, the Oregon Fish and Wildlife Department would need to develop a management plan and coordinate with other state agencies to take action and address the primary threats to orcas in Oregon. The commission is scheduled to decide whether to add the southern resident orca to the state’s endangered species list by February 2024.
The primary threats to southern resident orca survival include a lack of salmon to eat, pollution from chemicals and oil spills and disturbances from boats, including sounds from the boats.
