U.S. Interior Secretary Ken Salazar rejected a proposal to extend the lease of a popular oyster farm at Point Reyes National Seashore on Thursday, effectively ending more than a century of shellfish production on the 1,100 acres where Europeans first stepped foot in California.

The decision will allow the National Park Service to turn the picturesque bay where Sir Francis Drake landed more than 400 years ago into California’s first federally designated marine wilderness area.

Salazar made his decision a day before the 40-year lease allowing Drakes Bay Oyster Co., to harvest shellfish in the estuary expires and one week after visiting the site.
