The program, which began in 2003, selectively killed off the invaders with few adverse effects on the non-targeted native wildlife species.

Positioned at the eastern entrance to the Santa Barbara Channel, Anacapa was a natural choice for a lighthouse.

The Lighthouse Board decided to place a light on the island, but to limit the expense of building an offshore beacon, an unmanned acetylene lens lantern on a tower was erected in 1912.

Historical Information from Coast Guard web site:[4] Anacapa, a native-American word meaning "ever changing", was first discovered by Juan Rodríguez Cabrillo in 1542.

Her radiant 1.1 million candlepower light beacon, her bellowing foghorn and beeping radio signal have guided ships safely through the coastal channel since 1932, the date of construction.

The Coast Guardsmen and their families of the light station resided in the four large Spanish style white stucco houses with red tile roofs before the light station was automated in December, 1968.The buildings other than the lighthouse are now being utilized by the National Park Service.
