Summary

Suffolk County recognizes heritage and specimen trees through county Chapter 662 scenic-corridor designations and town-level codes such as East Hampton Code Chapter 256 and Southampton Town tree rules that protect large or historically significant trees.

Full Breakdown

While Suffolk County Code Chapter 662 sets a baseline for trees on county property, the East End towns of East Hampton, Southampton, Southold, and Shelter Island maintain heritage and specimen tree provisions tied to diameter at breast height thresholds, often 24 inches or larger, plus species designations for native white oaks, beeches, and tupelo. Removal requires a town tree-permit hearing with possible historic-preservation review where the tree contributes to a designated historic district. Brookhaven and other western towns operate similar but narrower tree codes typically applied during subdivision and site-plan review.

Violations & Fines

Unauthorized removal of a designated heritage tree can incur fines exceeding 5000 dollars plus replacement costs in the same caliper inches and bonded performance under town code.

Frequently Asked Questions

How do I find out if my tree is a heritage tree?

Contact your town building or environmental department. Most East End towns require a tree-permit pre-inspection that flags any heritage or specimen tree on the lot before approving construction.

Can I remove a dead heritage tree without a permit?

Even dead specimen trees typically need a permit to confirm hazard status. Document with arborist photos before removal; emergency removal is allowed but must be reported promptly.
