Fort Ord is a former United States Army post on Monterey Bay of the Pacific Ocean coast in California, which closed in 1994 due to Base Realignment and Closure action. Most of the fort's land now makes up the Fort Ord National Monument, managed by the United States Bureau of Land Management as part of the National Conservation Lands, while a small portion remains an active military installation under Army control designated as the Ord Military Community.
Before construction and official designation as a fort in 1940, the land was used as a maneuver area and field-artillery target range during 1917. Fort Ord was considered one of the most attractive locations of any U.S. Army post, because of its proximity to the beach and California weather. The 7th Infantry Division was its main garrison for many years. When Fort Ord was converted to civilian use, space was set aside for the first nature reserve in the United States created for conservation of an insect, the endangered Smith's blue butterfly. Additional endangered species are found on Fort Ord, including Contra Costa goldfields and the threatened California tiger salamander.
