Summer chum salmon in Hood Canal are making a remarkable comeback. Could it be enough to support their removal from the Endangered Species List?

Scientists are making the case that the world's orcas should be divided into two new species. Voting for the proposed change was scheduled to take place last week at the Society for Marine Mammalogy. [Update: Read about the decision here.]

Climate change could cause sea levels to rise more than four feet in some parts of Puget Sound, leaving shoreline residents with some tough decisions. Experts say fighting the waves with conventional seawalls may not be the answer.

The year 2025 has been fairly mystifying to experts who make their living studying natural systems in the Puget Sound region.Unusual observations this year include record-low dissolved oxygen levels, unexpected gray whale visitations, and the sudden arrival of an astounding number of short-tailed shearwaters — a seabird almost never seen in Puget Sound.Cold waters rising from the deep...

The recently approved HEAL Act requires the state of Washington to address issues of environmental justice within its agencies. The Act is expected to be signed by the governor and focuses on inequities in environmental health conditions for disenfranchised populations.

For close to 100 years, Seattle's Ballard Locks has been one of the region's busiest waterways, drawing major boat traffic along with millions of tourists. But as it prepares to celebrate its centennial, the aged structure is also drawing the concern of engineers. They worry that an earthquake could cause the locks to fail, draining massive amounts of water from Lake Washington and Lake Union. In some scenarios, the two lakes could drop by as much as 20 feet, stranding boats, disabling bridges and causing big problems for salmon restoration.

It has been four summers since a mother orca’s dramatic vigil brought worldwide attention to the plight of Puget Sound’s southern resident killer whales. A recent gathering of legal experts, conservationists, and academic scholars looked at how perceptions of the whales have changed since then and whether laws and policies should reflect new thinking about ethical responsibilities to orcas and other animals. 

Years of struggle have led to reduced pollution and a stronger sense of community in the Duwamish Valley. As cleanup efforts there continue, environmental justice has come front and center for the area's diverse populations.

How can Puget Sound generate more salmon? That question has been at the center of ecosystem recovery efforts for decades. But even as scientists and conservationists make progress on many fronts — from breaching dams to cleaning up the water — they have faced one especially complicated and frustrating limitation: Salmon need more estuaries. We look at how local tribes are working to restore this critical habitat.
