The Bureau of Agricultural Land Preservation works with the nine member Lehigh County Agricultural Land Preservation Board to preserve farmland within Lehigh County. The preservation of farmland is accomplished through the purchase of agricultural conservation easements (also known as the purchase of development rights) on eligible Lehigh County farm properties.

As of February 9, 2010, the Lehigh County Agricultural Land Preservation Board has protected 236 Lehigh County farms covering a total of 19,619 acres with perpetual agricultural conservation easements.
