Annual Lupine Bash

The Annual Lupine Bash is one of the largest restoration events coordinated by Friends of the Dunes and the US Fish & Wildlife Service. It takes place every February at the Lanphere Dunes Unit of the Humboldt Bay National Wildlife Refuge.

Annual Lupine Bash The tradition of "striking a blow for biodiversity" is started back in 1978 by John Sawyer and the California Native Plant Society. Three decades later the annual lupine bash continues. The population of yellow bush lupines has declined dramatically at the Lanphere Dunes but efforts must persist until the seed bank is completely diminished. The event occurs in February so as to remove all of the shrubs before they are able to produce flowers and release more seeds.

Yellow Bush Lupine (Lupinus arboreus)

Lupine Yellow bush lupine is native to central California, but this species is not native to Humboldt County. There are two other species of lupine that are considered to be native here, but are smaller and less commonly seen on the dunes. Yellow bush lupine was introduced to the North Spit in the early 1900ís when the railroad was being used to transport rock to construct the north jetty. Five women were hired by the Army Corps of Engineers to plant the lupine seeds along the railroad to prevent unwanted sand burial. The seeds were obtained by the Presidio in San Francisco.
