Humboldt Bay Dune Restoration

Created: 10/16/2018 - Updated: 7/19/2019

Abstract

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.
