Project Update: Supporting Community and Citizen Science at the Elwha ScienceScape Symposium

The removal of two large dams from the Elwha river in the ancestral lands of the Coast Salish peoples was the first large-scale dam removal of its kind in the world. This effort has inspired many other watershed-scale restoration projects and dam removal organizations both nationally and internationally. CCS has an important role to play in the Elwha: the Lower Elwha Klallam Tribe (LEKT) and other local communities were a large part of the original drive to remove the dams, and as funding and policy requirements sunset, ongoing monitoring will need to be increasingly taken up by stewards beyond federal and state agencies. For us at the Center for Community and Citizen Science, this place and moment offer a remarkable opportunity to help center participation in the ongoing stewardship of a world-renowned watershed-scale restoration project. How can we support and elicit ideas for public involvement in understanding the Elwha’s continuing transformation?

To mark the ten-year anniversary of the removal of the dams, the Elwha scientific community came together to coordinate sampling efforts, plan for future long-term monitoring, and synthesize data collected to date – an effort called “Elwha ScienceScape.” Supported by the Resources Legacy Fund (RLF), the ScienceScape effort built on their April workshop by holding a public event at Peninsula College and a science symposium at the NatureBridge Olympic Campus in late summer of 2022. We joined ScienceScape for these events to learn about the Elwha River’s first 10 dam-free years and to celebrate the successes of these groundbreaking restoration projects, while also recognizing ongoing downsides and areas for growth. We were also able to join agency and tribal scientists and community groups to observe (and participate in!) emerging participatory science projects. We had been discussing the past, present, and future of CCS on the Elwha with scientists and community organizations over the preceding four months, and we were excited to get a chance to experience the place in person, meet our collaborators face-to-face, and continue those conversations. 



Joining current CCS field sampling projects

Our trip included accompanying researchers and community partners as they jointly discussed taking up new forms of public participation in environmental monitoring. 

NOAA Scientists Sarah Morley and Aimee Fullerton work with Joel Green of Clallam County Streamkeepers and Ryan Meyer of the UC Davis Center for Community and Citizen Science to install new temperature loggers which can be downloaded with a smartphone.

For example, NOAA maintains a network of water temperature loggers throughout the watershed, providing crucial data used by scientists at the Lower Elwha Klallam Tribe, NOAA, USGS, Olympic National Park, and other organizations. A variety of local groups may be able to step in and help with crucial tasks such as periodic data downloads and monitoring the condition and positioning of each sensor in the network. On this trip, Joel Green, who leads the Clallam County Streamkeepers, explored ways of bringing Streamkeeper volunteers into the collective effort to sustain the temperature monitoring network, focusing on the front country loggers that are more easily accessible by car. Streamkeeper volunteers already track a variety of water quality measurements in the local area, but managing temperature loggers in the Elwha would be a new activity for them.

We accompanied NatureBridge staff members to meet with Sarah Morley from NOAA at the mouth of the Elwha to develop a stable isotope sampling activity for students. This contribution would provide valuable data for understanding how the aquatic food web is changing over time as salmon populations continue to rebuild following dam removal. Stable isotopes are used to track the origin of nutrients that pass through the system. If these nutrients are coming from the ocean, the implication is that salmon are bringing those nutrients up into the river system and benefiting the food web in ways that had been prevented by the dams for more than a century. 

We also joined USGS and Lower Elwha Klallam Tribe researchers as they deployed small mammal traps on one of the former reservoirs – continuing the study of how the river’s food web is changing as the landscape and vegetation continues to evolve since dam removal. This project often involves volunteers, but is not specifically designed as a citizen science project. Researchers noted that the relative tradeoff between the effort to bring volunteers along and the benefit the volunteers bring can vary over time, but noted that there have been times where the extra help was absolutely critical.


Elwha ScienceScape Public Event and Scientific Symposium

The public event – with well over 200 attendees! – featured speakers summarizing the state of the Elwha system 10 years after dam removal, giving a report on the current status of the upcoming Klamath River dam removals (slated to begin in 2023), on Dam Removal Europe and the work being done abroad, and on RLF’s regional work supporting dam removals in the American West. Following these presentations, the Peninsula College Longhouse ʔaʔkʷustəŋáw̕txʷ House of Learning graciously hosted a poster session.

The Longhouse is the first of its kind, representing a partnership between Tribes and the Community College, and we were grateful for their hosting and the presence and performance of the Lower Elwha Klallam Tribe drummers and singers who gave a welcome at both the presentations and the poster session. Poster presenters shared research on a variety of topics, and representatives from the National Park Service, NatureBridge, and Clallam Streamkeepers shared various outreach tools used by their organizations.

As part of the registration for the public event, we asked if registrants were interested in being involved in science and monitoring on the Elwha; over half said yes. In addition, we have noted that many of the questions currently being answered regarding the river system have been driven by regulations and policy, and the answers are currently driven largely by scientists. So we also asked registrants what questions they have about the Elwha River and its recovery since dam removal. We wanted to know what the community’s interests are in how things are changing, and how those interests align with the science that is happening.

Unsurprisingly, there was a lot of interest in how the fish have recovered, but there was also interest in many other aspects of the system (including sediment, vegetation, and wildlife). Most notably, there was interest in the human aspects of the dam removals – for example, asking how human uses of the river and opinions about the dam removal have changed and how people have benefited from the dam removals.



We then attended the three-day ScienceScape Symposium, hosted at NatureBridge. In addition to field trips to the Elwha estuary and former Aldwell reservoir, the occasional swim in Lake Crescent, and an early morning trip to see Chinook salmon spawning in a nearby stream, we engaged with the Symposium events in several ways. There were talks summarizing geomorphological changes, the evolution of vegetation in the former reservoirs, and the responses of food webs, fish, and wildlife, and many more talks about individual research projects on particular topics. We presented insights about the past, present, and potential future of CCS on the Elwha. These efforts vary in their past longevity and future feasibility, often depending on the availability of individuals who can maintain groups of volunteers and interface with agencies. 

During discipline-specific breakout groups (paralleling the groups from the April workshop), we heard CCS mentioned more frequently and confidently as a part of future plans for Elwha research. There was also strong interest from scientists in communicating more effectively with the public and addressing questions about human impacts of the dam removal. 

In our breakout session focused specifically on CCS, there was strong interest in working with youth, and in particular with Tribal youth as appropriate. There was potential for connecting with educators in Olympic National Park, programs at Peninsula College, and school programs at NatureBridge.

The future of CCS on the Elwha

We will continue to support existing CCS efforts including water quality measurements, river food web characterization, camera traps for wildlife monitoring, biodiversity observations via iNaturalist, and stable isotope measurements to track the influence of anadromous fish into the watershed. We will also support ScienceScape members in seeking longer-term funding to support CCS and CCS coordination into the future. Future project ideas include remote sensing analysis of vegetation change, birding (with eBird), fish genetics, photo resurveys of geomorphological change, subtidal dive surveys, beach grain size analyses, and back country surveys of a variety of ecological and other processes. 

Beyond the many important findings from the past decade of Elwha science, one thing is clear: there are still many fascinating and important questions to be answered about how ecosystems and landscapes respond to a restoration effort at this scale. The ScienceScape meeting afforded many different opportunities to discuss CCS approaches that can sustain and broaden that learning process. We are excited about where this might lead, both for the Elwha, and the broader field of citizen science and watershed restoration.
