Puget Sound ecosystem holding on, but recovery remains uncertain, says latest status report

Share

Efforts to restore ecological health to Puget Sound have largely failed to meet recovery goals, yet fish and wildlife populations are still hanging on, according to a new report that describes many struggling populations as neither increasing nor decreasing to a significant extent. The latest State of the Sound report, released last week by the Puget Sound Partnership, reveals the ongoing difficulty of recovering the Puget Sound ecosystem in the face of rapid population growth, climate change and a legacy of pollution and habitat damage. Yet the report, produced every […]

Prey and predators create varying life-or-death conditions for salmon, as shown with Atlantis model

Share

This article is the latest in a series about computer models and their uses within the Puget Sound ecosystem. As scientists uncover more and more information about a particular ecosystem, computer modelers are often eager to put that raw data to good use in complex models tuned to local conditions. One highly acclaimed model, called Atlantis, has been applied to more than 40 ecosystems around the world. In Puget Sound, Atlantis has been used to study the food web to determine whether salmon are more threatened by predators or by […]

New federal and state funding to study toxics in Puget Sound

Share

The Puget Sound Institute (PSI) and its parent organization the Center for Urban Waters (CUW) are the recipients of more than $3.2 million dollars in grants this month from the Environmental Protection Agency and the Puget Sound Partnership. The funds will go toward understanding and reducing emerging threats from toxic chemicals in Puget Sound. The grants — six in total — will support projects based at our labs at the University of Washington Tacoma. These include: The research builds on earlier work coming from the lab including the discovery of 6PPDQ, […]

Health of killer whales examined through Bayesian network modeling and informed predictions

Share

As part of a project exploring the technical uncertainties surrounding Puget Sound water quality, we are reviewing how computer models are used to advance our understanding of natural systems. This blog post is part of a series focused on different models and their uses within the Puget Sound ecosystem. The project is jointly sponsored by King County and the Puget Sound Institute. Qualitative network modeling, as shown in the previous post in Our Water Ways, is focused on actions that create either positive or negative results for actors in the model. […]

Shutdown looms for Alaska summer troll fishery; court order aims to provide more salmon for orcas

Share

Southern Resident killer whales, which frequent Puget Sound, are expected to benefit from more Chinook salmon later this year, as expressed in a court order calling for the suspension of a major troll fishery in Southeast Alaska. Alaska state officials are dismayed by the ruling, saying that closing this commercial fishery would have a devastating effect on fishing families in Alaska and on many small communities along the coast. The state has launched an appeal of the ruling. The court order, signed last week by U.S. District Judge Richard Jones […]

A new oral history project looks at the unique development of natural resource policy in Washington state

Our affiliates at the Center for Urban Waters and external partners will examine 50 years of collaborative leadership in the state leading to groundbreaking outcomes on forest, fish, wildlife, land, and water management. Funding secured to date includes generous gifts and pledges from Anchor QEA, the Jamestown S’Klallam Tribe, the Nisqually Tribe, the Puget Sound Partnership, the Port Gamble S’Klallam Tribe, the Squaxin Island Tribe, the Suquamish Tribe/Suquamish Foundation, the City of Tacoma, the Washington State Department of Fish and Wildlife, and Washington State University. Billy Frank Jr. was just […]

As winter approaches, salmon and orcas are still a commanding presence

Share

With salmon and orcas still on the move and facing ever-changing weather conditions, I thought it might be time for a brief update to my blog post of Nov. 21. At the time of the last report, the Puget Sound region had gone through a 13-day dry spell, which followed a period of brief and limited precipitation. Low stream flows were making it tough for chum and coho salmon to go upstream when they should have been at their peak of spawning. Many unfortunate fish were dying before they could […]

Add-on structure will begin to address steelhead crisis at the Hood Canal Bridge

Share

The Hood Canal Bridge, which connects the Kitsap and Olympic peninsulas, has proven to be a dangerous impediment to juvenile steelhead trout. As many as half of the young migratory steelhead in Hood Canal may get picked off by seals, birds and other predators as the fish try to pass under the floating highway, according to studies. While a permanent solution may be years away, the first step at reducing predation at the bridge may be just around the corner, as construction crews prepare to fabricate a floating structure that […]

New orca calf confirmed amid serious health concerns and actions to protect the whales

Share

A surprise visit by K pod on Saturday near Vancouver Island led to the official confirmation of a new orca calf born into the Southern Resident killer whale community. The new calf, designated K45, is the second baby born to the Southern Residents this year, as recorded by the Center for Whale Research, which maintains the official census. For K pod, this is the first confirmed calf to be born since 2011. The youngster was first reported on April 28 by a fishing guide cruising off the Oregon Coast. The […]

Governor’s renewed salmon strategy faces decisive period in the current Legislature

Share

State legislation designed to enhance salmon habitat by requiring protective buffers along streams has been set aside pending further discussions over the coming year. Meanwhile, several other salmon-protection measures proposed by the governor could move forward with decisive funding from the Legislature. The buffer bill (HB 1838), named the Lorraine Loomis Act, would prohibit degradation of streamside habitat while encouraging restoration within prescribed “riparian management zones” on both public and private lands. Such requirements would apply to farmland, areas destined for development and even properties undergoing redevelopment. The bill is […]

Understanding the cold-water needs of salmon and helping them to survive

Share

Salmon need cold water. This general statement is something I’ve been hearing since I first began reporting on these amazing migrating fish years ago. Cold water is a fact of life for salmon, known for their long travels up and down streams, out to saltwater and back. But colder is not always better. Questions about why salmon need cold water and how their habitat might grow too warm or too cold led me into an in-depth reporting project. I ended up talking to some of the leading experts on the […]

Salmon study sparks controversy

Share

Occasionally, this space includes reports and essays from guest writers on the subject of Puget Sound ecosystem recovery. Biologist and author Eric Wagner has this look at the controversy surrounding a recent study of salmon numbers in the Salish Sea.  By Eric Wagner A couple of weeks ago, the Canadian Journal of Fisheries and Aquatic Sciences published a research article from the Marine Mammal Research Unit at the University of British Columbia (UBC). The article, first-authored by a hydroacoustician named Mei Sato, looked at the abundance of Chinook salmon during […]
