SAN FRANCISCO — A historic Northern California oyster farm along Point Reyes National Seashore will be shut down and the site converted to a wilderness area, U.S. Interior Secretary Kenneth L. Salazar announced Thursday.
Mr. Salazar said he will not renew the Drakes Bay Oyster Co. lease, which expires Friday. The move will bring a close to a years-long environmental battle over the site.
"After careful consideration of the applicable law and policy, I have directed the National Park Service to allow the permit for the Drakes Bay Oyster Co. to expire and to return the Drakes Estero to the state of wilderness that Congress designated for it in 1976," Mr. Salazar said in a statement.
Mr. Salazar, who visited the oyster farm last week, said he did not make the decision lightly.
Point Reyes National Seashore was added to the national parks system by Congress in 1962, and protects more than 80 miles of California coastline.
The interior secretary also has the power to lease the park's lands for dairy and cattle-ranching purposes. Currently, there are 15 beef and dairy ranches operating along the Point Reyes seashore. Those ranches will remain open under the decision Thursday.
Oyster farm owner Kevin Lunny, whose family also operates one of the cattle ranches, said he was disappointed by the decision and was still trying to figure out his next move. He had been asking for a 10-year extension to his lease.
"This is going to be devastating to our families, our community and our county," Mr. Lunny said. "This is wrong beyond words in our opinion."
He said Mr. Salazar called to tell him about the decision.
Mr. Lunny will have to remove the oyster company's property from park land and waters within 90 days. Because the lease was set to expire anyway, the company gets no compensation for the decision.
Mr. Salazar did not stop all commercial activities in the park. He sought to extend the terms of the cattle ranch leases from 10 to 20 years.
"Ranching operations have a long and important history on the Point Reyes Peninsula and will be continued at Point Reyes National Seashore," he said.
Environmentalists and the National Park Service said the farm's operations threatened nearby harbor seals and other native species. The area is a key pupping site for the seals.
But the oyster farm decision had many powerful allies, who fought vociferously on its behalf. Sen. Dianne Feinstein, California Democrat, and the National Academy of Sciences claimed park officials were trying to get rid of the oyster farm by exaggerating its negative impact on the environment.
On Thursday, Mrs. Feinstein said she was "extremely disappointed."
"The National Park Service's review process has been flawed from the beginning with false and misleading science," she said in a statement.
"[This] effectively puts this historic California oyster farm out of business. As a result, the farm will be forced to cease operations and 30 Californians will lose their jobs."
