Salmon Habitat Restoration

Ecolution's salmon habitat restoration projects include ecological assessment, collaboration with engineering and design teams, permitting strategy, and technical compliance documents. Work focuses on fish passage, floodplain and riparian enhancement, and habitat evaluation, ensuring restoration actions are scientifically sound, cost-effective, and aligned with regulatory and recovery objectives.

Peer Review of Culvert Injunction Fish Passage Designs

Ecolution partnered with Smayda Environmental Associates and Fain Environmental to provide peer review of seven fish passage correction designs along Washington State Route 108. The review focused on evaluating instream and riparian habitat components to ensure the designs meaningfully improved fish and wildlife habitat while meeting federal injunction requirements.

Habitat Assessment and Restoration Design

Ecolution has provided habitat assessment and restoration design support for multiple salmon habitat restoration projects throughout the Lower Columbia subbasin and surrounding regions. Working with engineering partners and stakeholders, Ecolution conducted field studies, analyzed stream and riparian habitat conditions, identified restoration opportunities, and supported design development and project prioritization across a range of river and stream systems.

Ecolution was retained by the Mason Conservation District to support a fish passage enhancement project for Spring Chinook in the South Fork Skokomish River in partnership with the Skokomish Tribe. Dr. Tyler is developing the permitting strategy and leading stakeholder coordination for this complex, multi-agency project located on U.S. Forest Service lands. Work includes scoping NEPA review, threatened and endangered species surveys, and biological assessments to support approvals from USFWS and NOAA.
