Restoring the milelong stretch of Wallowa River that runs through their family ranch near Lostine realized a longtime dream for Ian and Heidi Wilson. The ranch has been home to five generations of Wilson and Haun families. And the river is home to many fish species, including Chinook salmon, summer steelhead, and bull trout.
In partnership with Trout Unlimited and Grande Ronde Model Watershed, the family worked to reconnect the Wallowa's floodplain and restore important spawning and rearing habitat. With an overall focus on bringing back natural processes, this project aimed to create more habitat and increase habitat complexity and ecosystem function. Work included adding side channels, placing logs, building beaver dam analogs, and planting thousands of native trees.
Their efforts lead to remarkable results. Water surface area in the floodplain went from 3 acres to 25 acres, adding important habitat. Salmon and steelhead appreciated that 700 percent increase, with spawning and rearing activity already observed.
Attracting beavers was a big goal for the family, said Ian Wilson, who’s a trained fisheries biologist and restoration project manager for the Grande Ronde Model Watershed. “We wanted them to take over long-term stewardship, and not rely on future man-made intervention,” he said. “We wanted the original stream restorers to come in and do their thing.”
Within two months of project completion, for the first time in nearly 25 years, beavers got back to work as stewards of the stream.
The project team includes Wolf Water Resources, BCI Contracting, Anabranch Solutions, Plantworks, and Wildlands. Partners included the Wallowa Implementation Team: the Nez Perce Tribe, U.S. Forest Service, Oregon Department of Fish and Wildlife, Wallowa Resources, NOAA Fisheries, and Bonneville Power Administration.
