WELCOME TO NWSA ONLINE!

Mission Statement: We are a network of professional and amateur scientists from diverse disciplines that provides support and a forum for research and education relevant to the environment and resource management of northwestern North America. To accomplish our mission, the association publishes a quarterly journal, convenes an annual scientific meeting, and awards student research grants.

Since 1923, the NWSA has existed for the purpose of promoting scientific research and disseminating scientific knowledge. Our annual meetings are held throughout the Pacific Northwest and provide an opportunity to share recent findings and foster collaborative interactions.

NWSA publishes four issues of Northwest Science each year. A peer reviewed journal, Northwest Science is an outlet for original papers on wide ranging topics in the natural sciences, including anthropology, aquatic biology, botany, ecology, fisheries, forestry, geology, geography, hydrology, soils, wildlife biology, and zoology. The geographic scope of Northwest Science is the northwestern United States and western Canada.


Announcements

  • Mar 12, 2026

    Last October we announced that Northwest Science had enrolled in BioOne's Subscribe to Open (S2O) pilot, under which Northwest Science articles would be published Open Access at a cost to authors of only the standard page charges. The catch was that BioOne had to attract enough S2O institutional subscriptions to meet financial viability. We can now confirm that this subscription threshold has been passed, so S2O is live! See the full announcement or the Northwest Science homepage for more details.

  • Oct 6, 2025

    Northwest Science will participate in the BioOne Subscribe to Open (S2O) program from January 2026. This pilot program will provide authors with open access publication at greatly reduced cost and enable free-of-charge access to current-year Northwest Science articles.

    Five new members join NWSA's Board of Directors after recent elections. Welcome to Brooke Bain-White, Dylan Fischer, Andrew Merschel, Richard Waitt, and Dana Warren!
