The Pinelands Development Credit Program — Market-Based Land Preservation in New Jersey's Pine Barrens

The Pinelands National Reserve, the first U.S. National Reserve designated by Congress in 1978, covers about 1.1 million acres of southern New Jersey and overlies the Kirkwood-Cohansey aquifer, one of the largest and purest in the United States.

The Pinelands Development Credit (PDC) programme, created in 1981 under the Pinelands Protection Act and Comprehensive Management Plan, aims to permanently preserve ecologically sensitive Preservation Area and agricultural land while still allowing regional housing growth.

Landowners in sending areas receive tradeable credits (each worth roughly four housing units in a Regional Growth Area) in exchange for a permanent deed restriction, and a dedicated PDC Bank, established in 1985 and administered by the Commission since 2011, buys, holds and resells credits when private demand is thin.

By 2022 the programme had permanently preserved 57,268 acres, part of 480,500 acres (51% of the Pinelands Area) protected overall as of June 2021, through more than 1,200 completed transactions worth roughly $63 million.

An independent academic case study calls the PDC programme one of the world's oldest and most successful transfer-of-development-rights schemes, though a Resources for the Future evaluation cautions that landowners retaining partial rights can still produce scattered, low-density development rather than fully contiguous conservation.
