Can nature make you happy? Science weighs in: A recent study by PSI social scientist Kelly Biedenweg found that Puget Sound residents reported increasing happiness the more they engaged with the natural environment.

“We (in the Pacific Northwest) are pretty much the leaders in trying to understand how happiness and integration with the environment relate to each other,” Biedenweg told The News Tribune, which featured the study in its April 7th edition. Biedenweg has been working with the state of Washington to identify indicators of human well-being such as happiness, physical and psychological health and economic prosperity for the Puget Sound region.

The study was published in the Journal of Environmental Psychology and was funded by The National Science Foundation and the Environmental Protection Agency. It was based on online surveys of 4,418 area residents across eleven Puget Sound counties.

A version of The News Tribune story was also published on April 9th in The Olympian.

Although eelgrass populations have declined in some parts of Puget Sound, overall numbers for the aquatic plant have remained steady ecosystem-wide, according to an analysis of 41 years of data from the Washington Department of Fish and Wildlife.

The study, published in the Journal of Ecology, was co-authored by Puget Sound Institute lead ecosystem ecologist Tessa Francis and was aided by a team of University of Washington student assistants who sorted through more than 160,000 notebook entries to parse out survey findings.

The data comes from long-time surveys of Pacific Herring, which also included the detailed observations of eelgrass abundance. (We first wrote about this treasure trove of hand-written notebooks in a PSI blog focusing on its implication for herring studies.) The paper was co-authored by a team of scientists from NOAA, PSI, Earth Resource Technology, The Nature Conservancy, WDFW and the University of Washington School of Environmental and Forest Sciences.

The researchers say the findings give some hope that eelgrass meadows may be more resilient than expected to pressures such as climate change, but they caution that sharp declines in some areas are a source of concern.

“The fact that eelgrass has been stable over the last 40 years tells you that things are probably not getting worse, but it doesn’t mean that things are good,” study co-author Phil Levin, of the University of Washington and The Nature Conservancy told the Seattle Times today.

PSI’s Francis was also quoted in the Seattle Times story and called the findings “promising in terms of recovery, because it’s a lot easier to think of what we might do on a local scale, than to think of what we might do on a grand, ecosystem scale.”

Eelgrass is an aquatic flowering plant that provides important habitat for young salmon, herring, Dungeness crabs and many other species. You can read about efforts to restore eelgrass beds in Puget Sound in our magazine series Salish Sea Currents.

This year has been as busy as any we have had since our founding in 2010. As we look forward to year seven (!) of our organization, we have put together a sort of highlight reel of accomplishments.

At various points, PSI scientists worked to prioritize emerging contaminants in our waterways. We studied the health of forage fish populations, analyzed eelgrass abundance and brought together key scientific findings for Puget Sound’s marine and nearshore. 

Most recently, our team began helping to develop new state and federal Implementation Strategies that will prioritize future Puget Sound cleanup efforts (you can read more about the Implementation Strategies in the Encyclopedia of Puget Sound).

Through it all, we have kept you informed with dozens of articles in our magazine Salish Sea Currents, as well as many new papers in scientific journals. After a strong 2016, we believe that science is more vital than ever to Puget Sound recovery. We look forward to building on our accomplishments in 2017.

A comparative study of human well-being indicators across three Puget Sound regions

Puget Sound Institute social scientist Kelly Biedenweg has published a comparative study of three well-being indicators in the Puget Sound region. The article appears in the August issue of the journal Society & Natural Resources.

Abstract:

Simple frameworks that generalize the best metrics of human well- being related to the natural environment have rarely been empirically tested for their representativeness across diverse regions. This study tested the hypothesis that metrics of human well-being related to environmental change are context specific by identifying priority human well-being indicators in distinct regions. The research team interviewed 61 experts and held 8 stakeholder workshops across 3 regions to identify and prioritize locally relevant indicators. Results from the three regions were compared to determine the degree of geographic and demographic variability in indicator priorities. The team found broadly similar domains and attributes of human well- being across the regions, yet measurable indicators were specific to the contexts. Despite this, the congruence of overarching domains suggests that a high-level framework of human well-being can guide a holistic assessment of the human impacts of environmental change across diverse regions.

Graphic from ‘Thirty-two essential questions for understanding the social–ecological system of forage fish: the case of Pacific Herring’

A new paper co-authored by PSI’s Tessa Francis connects social and ecological factors influencing herring management in the Salish Sea. The paper, published in the journal Ecosystem Health and Sustainability, grew out of a three-day workshop held last year in British Columbia. The workshop was sponsored by The Ocean Modeling Forum, a collaboration between the School of Aquatic and Fishery Sciences at the University of Washington and NOAA Fisheries. It brought together a variety of herring experts, from commercial fishermen to scientists, regulators and members of regional tribes. NOAA’s Phillip Levin was the paper’s lead author, with Nathan Taylor of Fisheries and Oceans Canada and Tessa Francis, lead ecosystem ecologist at PSI, as co-authors.

New papers look at ‘zombie’ steroids

They are sometimes called ‘zombie’ chemicals. Some compounds thought to be safe and inactive can change into dangerously active forms when they are exposed to the environment. Two recent papers co-authored by PSI collaborator Ed Kolodziej look at some of the ways that regulators may need to account for these transformations.

Impacts of diving ducks on herring populations

Herring productivity in relation biomass (Francis et al.).

Puget Sound Institute Lead Ecologist Tessa Francis attended the 2015 meeting of the International Congress for Conservation Biology earlier this month in Montpellier, France. She presented results from her recent work with colleagues at NOAA’s Northwest Fisheries Science Center evaluating the impacts on Puget Sound herring populations of herring egg predation by seabirds and other predators.

The group is evaluating the causes of local declines in herring subpopulations, or “stocklets,” and suspect that heavy egg predation by diving ducks, especially scoters, may be preventing some herring populations that are already at low levels from recovering. Using a combination of in situ incubations and predation exclusion devices, Francis and her colleagues estimated that predation accounted for between 75 and 99.6% of egg mortality in several Puget Sound stocklets, including the sharply declining Cherry Point herring stocklet. They further found that high egg mortality rates are associated with stocklets that have been declining in recent years or decades.

Pacific herring are a foundational species in Puget Sound, owing to their critical position in the marine foodweb, and the Puget Sound Partnership has set recovery targets for herring. These results suggest that an assessment of the impacts of early life stage mortality on population trends, and prospects for recovery, warrants further investigation.

A Seattle Times story features a recent paper in the Marine Ecology Press Series about shifting baselines in the Puget Sound food web. Forty years of data from the Washington Department of Fish and Wildlife reveal a trend toward more jellyfish and less of some forage fish species in the region. High amounts of jellyfish can mean a decline in ecosystem productivity, according to scientists. The original paper was based on some of the same data used by Puget Sound Institute researchers looking at trends for Puget Sound’s Pacific herring populations.

Paper says spawning herring show little preference for vegetation

Pacific herring are known to lay their eggs on a wide variety of submerged vegetation, from algae to seagrass. A new study in the Marine Ecology Progress Series reports that Puget Sound herring show little preference when it comes to these types of spawning vegetation. The paper, co-authored by Puget Sound Institute Lead Ecologist Tessa Francis, analyzes herring egg loss on five types of vegetation in several herring subpopulations in Puget Sound. Authors include Andrew Shelton, Tessa Francis, Gregory Williams, Blake Feist, Kurt Stick and Phil Levin.
