The majority of states have direct funding sources for conservation. Commonly used funding sources include real estate transfer tax, legislative bonds, and lottery proceeds. For instance, in 2014, New Jersey added conservation funding from corporate business taxes through constitutional amendment, approved by 65% of voters. Many states and counties have programs for the purchase of agricultural conservation easements (PACE) to protect productive farmland from non-agricultural development. In 1974, Suffolk County in New York enacted the first PACE (also known as purchase of development rights or PDR) program. King County in Washington and the states of Maryland, Massachusetts, and Connecticut quickly followed suit. As of 2016, the PACE program operates in 32 states through both state and local programs.
