The Big Sur Land Trust is a private 501(c)(3) non-profit located in Monterey, California, that has played an instrumental role in preserving land in California's Big Sur and Central Coast regions. The trust was the first to conceive of and use the "conservation buyer" method in 1989 by partnering with government and developers to offer tax benefits as an inducement to sell land at below-market rates. As of 2016, it has protected around 40,000 acres (16,187 ha) through acquisition and resale to government agencies. It has added conservation easements to another 17,000 acres (6,880 ha) and has retained ownership of a number of parcels totaling about 4,500 acres (1,821 ha).
