Efforts to help improve Coho salmon habitat at Muir Woods National Monument in California are scheduled to begin in August, with crews removing previously placed boulders in Redwood Creek and then revegetating the creek with native plants.

To conduct the Salmon Habitat Enhancement Project work, fish in the creek will be relocated out of harm’s way, and then the work zone will be drained of water. Part of the project involves replacing four foot bridges across the creek. After work is completed, the restored creek banks will be re-vegetated with native plants and the project area will be closely monitored by biologists as it recovers.

The project is part of the so-called Redwood Renewal, which involves a series of projects implemented between 2018 and 2023 to improve and safeguard the monument's habitat. This initiative is intended to ensure evergreen preservation of the coastal redwoods and a healthier Redwood Creek through a mix of projects at Muir Woods.

Visitors will see trails built, trails retired that are too close to the creek, water/wastewater rehabilitation upgrades, a new lift station, and salmon habitat improvements to assist the return of Coho salmon. These projects will be on-going until final completion in 2023 to create a resilient Redwood Creek, according to the Park Service.

This September, work is scheduled to begin on critical components of the water and wastewater collection systems. While this work is underway, visitors may experience some temporary trail closures. Park staff will be on-hand to answer questions and signs will be posted indicating trail status.
