  • NOAA Technical Memorandum NMFS-NWFSC-97

    Protocols for Monitoring Habitat Restoration Projects in the Lower Columbia River and Estuary

    February 2009

  • NOAA Technical Memorandum NMFS-NWFSC Series The Northwest Fisheries Science Center of the National Marine Fisheries Service, NOAA, uses the NOAA Techni- cal Memorandum NMFS-NWFSC series to issue scientific and technical publications. Manuscripts have been peer reviewed and edited. Documents published in this series may be cited in the scientific and technical literature.

    The NMFS-NWFSC Technical Memorandum series of the Northwest Fisheries Science Center continues the NMFS- F/NWC series established in 1970 by the Northwest & Alaska Fisheries Science Center, which has since been split into the Northwest Fisheries Science Center and the Alaska Fisheries Science Center. The NMFS-AFSC Techni- cal Memorandum series is now being used by the Alaska Fisheries Science Center.

    Reference throughout this document to trade names does not imply endorsement by the National Marine Fisheries Service, NOAA.
