New York State Department of Environmental Conservation

The New York State Department of Environmental Conservation (informally referred to as NYSDEC, DEC, EnCon or NYSENCON) is a department of New York state government. The department guides and regulates the conservation, improvement, and protection of New York's natural resources; manages Forest Preserve lands in the Adirondack and Catskill parks, state forest lands, and wildlife management areas; regulates sport fishing, hunting and trapping; and enforces the state's environmental laws and regulations. Its regulations are compiled in Title 6 of the New York Codes, Rules and Regulations. It was founded in 1970, replacing the Conservation Department, and is headed by Basil Seggos.

NYS DEC had an annual budget of about $2,588 million for FY 2024, and employs roughly 3,000 people across New York State. It manages over four million acres (16,000 km²) of protected state-owned land and another 910,000 acres (3,700 km²) of privately owned land on which it holds conservation easements. The department's activities go beyond land management and environmental enforcement to include the publication of a magazine and a state bird atlas, and the operation of 52 campgrounds in the Adirondack and Catskill Parks.
