Northwest Water Research Initiative

One of the most critical resources from forested landscapes is water. National forests and grasslands supply some of the purest water in the country, serving more than 60 million people in 33 states. Water from national forests also supports fish and wildlife habitat and recreational opportunities, among many other uses.

Water is key to the health of forest and aquatic ecosystems to the prosperity of agriculture, tourism, and other industries. Understanding where water comes from and how to manage it has singular scientific, political, environmental, and economic relevance.

The Pacific Northwest Research Station has a long legacy of innovation in watershed sciences. Hydrology, aquatic ecology, fish biology, and, the effects of forest and rangeland management on watersheds are just some of our areas of expertise. Given very high interest from land managers and other partners about this topic, the PNW Research Station has developed the Northwest Water Research Initiative and grounded it in the current information needs of resource managers and policy makers.

The Northwest Water Research Initiative will develop new knowledge focused on increasing the resilience of watersheds to rapid environmental change, including increasingly extreme events. The initiative emphasizes scientific inquiry that explicitly addresses the impacts of this change on increasingly novel ecosystems with highly variable conditions. Our questions will be geographically focused on the forests and rangelands of Alaska, Washington, and Oregon, and guided by the diverse people who live, work, and play here. This includes indigenous communities that rely on water, salmon, and other First Foods that these landscapes provide.

The work under this initiative is organized around three themes that ranked high on the list of our partners’ information needs:

• Water quantity and quality. We are undertaking research to better understand the factors controlling streamflow and water quality, including the effects of extreme events such as drought, floods, and severe wildfire. 
• Aquatic ecology. We are assessing change and projecting how it is likely to affect the structure, function, and biodiversity of aquatic and riparian ecosystems, including First Foods and other subsistence resources. 
• Aquatic-riparian ecosystem management and restoration. We are conducting research and developing tools that guide the work of aquatic and riparian restoration. 

Collectively, this work will strategically employ the PNW Research Station’s unique set of strengths: 

• Close connections with land managers. 
• Unrivaled access to experimental forests and rangelands and other diverse land and riverscapes where research can be conducted. 
• Highly skilled cadre of research hydrologists, geomorphologists, ecologists, and other scientists.

Many partners have helped shape this initiative and will continue to advance and refine the work as it progresses. This allows us to ask the most useful questions, develop the most accessible information tools, and ultimately maximize delivery of relevant new knowledge about expanding extremes and their effect on watersheds in a rapidly changing world.
