S.C. Code Ann. § 48-59-140

When trust funds are used to purchase a conservation easement on land, the conservation easement will be the controlling legal document regarding what is and what is not permitted upon the land, how the land will be preserved, and what rights are vested with the eligible trust fund recipient or its assigns which hold the conservation easement. If any inconsistencies or ambiguities arise between the provisions of this chapter and the terms and conditions of a conservation easement purchased with trust funds, the terms and conditions of the conservation easement must prevail. The board must exercise due diligence to assure the terms and conditions of conservation easements are consistent with the purposes of this chapter before disbursing trust funds for the purchase of such conservation easements.
