The farm was purchased by the National Park Service in 1972, and the agency issued a permit to allow the previous owner to continue operations for 40 years. The business was sold to a new owner in 2004, the Drakes Bay Oyster Company, who was informed by the NPS at the time of purchase that their permit to operate would not be renewed beyond the November 30, 2012 expiration date. A federal law enacted in 2009 authorized, but did not require, Interior Secretary Ken Salazar to renew the permit. The NPS and conservation groups viewed the farm as an inappropriate and environmentally-insensitive use of the estero, which was designated a "potential wilderness area" by Congress. The farm's supporters argued that it was not ecologically harmful and was important to the local economy.
