Smith-Root eDNA sampler collecting and filtering water from a tributary of the Okanogan River. Researchers are looking for traces of environmental DNA from spring-Chinook salmon that were reintroduced in the river. 

This dashboard displays summary data for portions of wildland fire perimeters (polygons) that occur within the selected filters. To display fire trends, it is recommended to filter out the smallest fires - those less than 1,000 acres. For large queries, please allow the tool a minute to process the request.

This dashboard displays summary wildfire data for those areas of raster wildfires that occur within the selected filters. Change the dashboard view with the filters across the top. Hover over data in each visualization for more information. Rows resize to fit the selected data. You may need to select more narrow filter options to obtain the best visual results.

The former Mills reservoir restoration area on the Elwha River in Olympic National Park, WA. This photo taken from the Glines overlook shows the revegetation that has occurred at the former reservoir post-dam removal.

An elk photographed by a trail camera positioned near the Elwha River, WA. Researchers are using trail cams to monitor wildlife recovery, use of, and interaction with areas restored after the removal of two dams on the river.

Field technicians Marcus Rehrman and Maddie Zickgraf surveying for Oregon spotted frogs in Deschutes County, OR. Field survey data helps researchers keep tabs on the status of this threatened species.

Researchers at the Pacific Northwest Environmental DNA Laboratory designed artificial flowers to attract pollinators. DNA left behind on the flowers can be collected and analyzed as a non-invasive way to survey for pollinator species diversity and abundance.
