Draft Environmental Assessment for the Humboldt Bay National Wildlife Refuge Sea-Level Rise Adaptation Demonstration Project

The Draft Environmental Assessment (DEA) was prepared by the U.S. Fish and Wildlife Service to evaluate the potential for impacts that could result from the proposed Humboldt Bay National Wildlife Refuge Sea-Level Rise Adaptation Demonstration Project. The Draft EA will be available for a 30-day public review period from April 24 until May 23, 2015. The proposed Sea-level Rise Adaptation Project would be located on the Bair parcel of the Lanphere Dunes Unit, Humboldt Bay National Wildlife Refuge. The proposed Action includes the removal of up to 4 acres of invasive, non-native European beachgrass and iceplant from the foredune of the Bair parcel, followed by revegetation with native species. Beachgrass would be removed with shovels to detach rhizomes while the top of the plant is pulled to either be burned in piles or taken to an off-site composting area. Iceplant would be removed by hand-pulling to remove rhizomes prior to being bagged and transported to a composting facility. Resprouts would be pulled weekly/every other week for one or more growing seasons. Following initial beachgrass and iceplant removal but prior to the next rainy season, native dune mat plants (cuttings, root divisions and seeds) would be planted in six of eight experimental areas to compare changes in dune morphology and sediment dynamics (deposition, deflation) with that of the two experimental areas where no removal would initially occur. The project may be phased over a period of years depending on funding availability. View the Draft EA/IS via the link below. Printed copies will be available at the Richard J. Guadagno Headquarters & Visitor Center, 1020 Ranch Road, Loleta, California, and at the Humboldt Coastal Nature Center (Friends of the Dunes), 220 Stamps Lane, Manila California. Questions or comments regarding the Draft IS/EA may be submitted via U.S. Mail to: Eric Nelson, Refuge Manager, Humboldt Bay National Wildlife Refuge, P.O. Box 576, Loleta, California. E-mail to: eric_t_nelson@fws.gov. Comments must be received no later than May 23, 2015.

  • Youth Conservation Corps Opportunity

    The Youth Conservation Corps is a summer employment program for young men and women, ages 15 through 18, who work and learn together by accomplishing needed conservation work on public lands. The eight week program will begin on June 22, 2015 and conclude on August 14, 2015. Participants will be selected by random drawing and will earn $9.00 per hour. All participants must bring a lunch and be able to provide their own transportation to and from the refuge. Work schedules will begin at 8:00AM and conclude at 4:30PM each day, Monday through Friday. The type of work to be performed includes: invasive plant control, wildlife habitat maintenance, basic construction, facilities maintenance and environmental education. Forty hours of natural resource conservation education programs will be incorporated into the scheduled eight weeks. These programs will provide information on the natural resources and responsibilities of the National Wildlife Refuge System.

  • Birds Love Humboldt!

    BirdsLoveHumboldt Thomson 150x138

    Migratory Birds descend upon Humboldt Bay year round as they migrate from chilly northern breeding grounds to warmer wintering areas. These birds use the productive Refuge habitats ranging from freshwater wetlands to sandy forested dunes.

  • Combating Invasive Spartina

    SpartinaWeedWhacking 150

    Historically the Humboldt Bay area had approximately 9,000 acres of valuable saltmarsh habitat. Because of levee construction in the early 1900's, which inhibited saltwater intrusion into historic marshes, salt marshes began to disappear, and now only 900 acres remain. The remaining acres are now being invaded by a robust grass known as Spartina. If left untreated, Spartina can take over an entire saltmarsh, completely eradicating all native species and becoming a monoculture. Through restoration work, the Refuge is combating the Spartina invasion to protect Humboldt's remaining saltmarsh habitat.

  • Humboldt Dune Restoration

    DuneRestorationAfter 150x116

    The Refuge’s Lanphere Dunes Unit is home to the first dune restoration project on the west coast. Restoration began in the 1980s with early experiments to control invasive European beachgrass (Ammophila arenaria). By the early 1990s The Nature Conservancy (the past owner) began a large-scale mechanical eradication project that took 6 years to complete. This project became a template for dune restoration projects throughout the west coast and beyond. Most importantly, it demonstrated that by removing over-stabilizing beachgrass and other invasive plants, essential dune processes were restored, fostering the recovery of the ecosystem. Since that time, dune restoration has continued to evolve and expand. On our local dunes, over 7 miles of coastline have been restored in Humboldt and Del Norte counties, and plans are in the works that will more than double this number.
