Suffolk County Code Chapter 662 establishes the County Tree Preservation Law, regulating tree removal on county-controlled property and within scenic and protected corridors, while delegating most private-property tree rules to towns and villages.
Chapter 662 of the Suffolk County Code governs tree preservation on county property, scenic roadways, and county parkland, requiring permits for removal of qualifying trees by diameter at breast height. Most private-residential tree removal authority sits with the host town or village, which often regulate trees over a specified DBH or species class such as native oaks. Within the Pine Barrens Commission jurisdiction, tree clearing limits are stricter and tied to lot-clearing thresholds. The Suffolk County Department of Parks, Recreation and Conservation administers county-property permits.
Unpermitted removal of regulated county trees triggers replacement requirements typically two-to-one in caliper inches, plus civil penalties up to 1500 dollars per tree under Chapter 662 and parallel town codes.
