Siletz Bay Reclaims Tidal Riches
12 Aug
Summary
- 37 acres of coastal wetlands are being restored.
- Natural tidal flows are returning to altered land.
- Habitat, water quality, and flood resilience will improve.
Oregon's Siletz Bay National Wildlife Refuge is currently the site of a significant wetland restoration project focused on the Drift Creek Unit. Crews are actively working to restore 37 acres of tidal wetlands, reversing over a century of landscape alteration due to diking and conversion for agriculture.
The primary objective is to re-establish natural tidal flows. This involves filling old drainage ditches and digging new tidal channels designed to mimic historical waterways. These changes are intended to improve crucial ecological functions, such as providing better habitat for fish and wildlife and enhancing water quality.
Beyond habitat improvement, the project aims to increase flood resilience. By reconnecting the floodplain with the tidal system, water will be able to spread more naturally, mitigating flood risks. The restored wetlands will also aid in filtering sediment and nutrients from upstream flows.
This initiative is part of a larger, multi-year restoration effort. A prior phase completed in 2023 successfully restored 41 acres, demonstrating positive regeneration of native vegetation and habitat since its completion.
Numerous organizations, including the U.S. Fish and Wildlife Service and the Confederated Tribes of Siletz Indians, are collaborating on this vital project. The ultimate goal is to ensure the floodplain functions as a natural tidal wetland, supporting a healthier coastal ecosystem.
