Tillamook Riparian Restoration Effort
An award-winning project, the Tillamook Riparian Restoration Effort (TRRE) began in fall of 2003 in an effort to enhance the quality of streams in the BLM's Tillamook Resource Area (TRA) in the Salem District. Nine partners, including several watershed councils and the National Fish and Wildlife Foundation, are working to improve stream quality throughout the watershed. Many of the streams in the TRA are or were non-compliant with the temperature standards set by the Clean Water Act. As an effect, many salmon populations are struggling. Partners in the effort have concluded that the cover, stabilization, and filtration provided by native plants is needed within TRA riparian areas. By removing invasive species such as Himalayan blackberry and Reed canary grass and replacing them with natives, the TRRE has been able to increase stream cover, reduce stream temperature, and mitigate stream bank erosion. The BLM's TRA botanist has led the effort since its inception and promotes using both deciduous and coniferous trees as a means to create relatively quick cover and return nutrients to the surrounding soils and streams.
Since the project's beginning, about 30,000 trees and shrubs have been planted along streams within the Tillamook Resource Area. In 2008, the Oregon Youth Authority's Camp Tillamook propagated about 12,000 plants while Horning Seed Orchard grew about 15,000 plants for the restoration projects. Also that year, the Tillamook Resource Area cooperated with 359 landowners and planted about 50,500 trees and shrubs along 27.5 miles of stream and 8.5 acres of wetland while continuing to maintain over 55 miles of existing plantings. The effort has restored about 185 miles of stream and 72.5 acres of wetland.
