Large-scale experiment on the rural Olympic Peninsula to test innovations in forest management

A young section of forest within the Olympic Experimental State Forest.

Before humans intervened in forest ecosystems, disturbances such as fire, wind storms and diseases wracked segments of the landscape, killing off swathes of trees and providing spaces for regrowth. Today, forest conditions are largely constrained by logging and conservation strategies, but scientists are recognizing the ecological and community benefits of letting a forest behave in more natural patterns. Scientists at the University of Washington and the state Department of Natural Resources intend to test a management approach that mimics natural disturbance patterns and processes across a portion of the Olympic Peninsula, an area known for having the most rainfall in the lower 48 states, high tree-growth rates and old-growth forests, part of which remain today.

Investing in fisheries management improves fish populations

Research published this week in the Proceedings of the National Academy of Sciences suggests that successful fisheries management can be best achieved by implementing and enforcing science-based catch or effort limits. The study is authored by researchers from the University of Washington and California Environmental Associates. The paper shows that, among 28 of the world’s major fishing nations, there is wide variation in the effectiveness of fisheries management systems at meeting their objectives for productive fish populations.

2 UW scientists lead effort to craft ‘blueprint’ for holistic fisheries management

Two University of Washington professors are leading an effort to help U.S. fisheries consider the larger marine environment, rather than just a single species, when managing a fishery. Tim Essington, a UW professor of aquatic and fishery sciences, and Phil Levin, a UW professor of practice with the School of Environmental and Forest Sciences and lead scientist at The Nature Conservancy, head a taskforce convened by the Lenfest Ocean Program to guide managers on implementing ecosystem-based fisheries management.

Large forest die-offs can have effects that ricochet to distant ecosystems

Abigail Swann, Dave Minor and Juan Villegas take measurements of live and dead trees in central New Mexico.

Major forest die-offs due to drought, heat and beetle infestations or deforestation could have consequences far beyond the local landscape. Wiping out an entire forest can have significant effects on global climate patterns and alter vegetation on the other side of the world, according to a study led by the University of Washington and published Nov. 16 in PLOS ONE. “When trees die in one place, it can be good or bad for plants elsewhere, because it causes changes in one place that can ricochet to shift climate in another place,” said lead author Elizabeth Garcia, a UW postdoctoral researcher in atmospheric sciences.

Mislabeled seafood may be more sustainable, new study finds

With seafood, what you see isn’t always what you get. It’s no secret that mislabeling is rampant around the world. Recent studies estimate up to 30 percent of seafood served in restaurants and sold in supermarkets is actually something other than what is listed on the menu or label. Why mislabeling happens is a little squishier. Fraud, human error or marketing ploys — combined with an often multicountry traverse from boat to restaurant — make it possible you are eating a different fish than what’s on the menu.
