Summary: The Cook Creek Riparian Enhancement Project restored 4 miles of stream habitat by employing well tested silviculture techniques to increase conifers along the riparian areas for future large wood recruitment. Cook Creek is a tributary of the Lower Nehalem River. The confluence is located approximately 6.5 miles above the head of tidewater and is the one of the largest sub-basins in the Lower Nehalem Watershed Council (LNWC) boundaries. The stream has approximately 8 miles of coho habitat and also supports Chinook salmon as well as steelhead and cutthroat trout.
Previous ODFW and LNWC habitat surveys determined this sub-basin lacks adequate conifers and therefore poor future large wood recruitment, and multiple streamside locations are dominated by invasive plant species. This project resulted in considerable conifer planting (12,000 mixed conifer species), manual hemlock seeding (approx. 1 million seeds), and in several camping areas non-native plant removal (Scotch broom and Himalayan blackberry). Implementation of the project, future tree release prescriptions, and all effectiveness monitoring reports was completed through the combined efforts of Boswell Consultants, LNWC, ODF, ODFW, and BLM. OWEB funds were utilized for riparian planting materials and labor, purchasing and installing tree
cages and fence materials, labor for invasive plant removal costs, and some additional overhead costs for project management and fiscal administration.
