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.
