Full Breakdown

Rockland County towns regulate heritage trees through municipal tree preservation laws. Clarkstown Town Code Chapter 214 (Trees) and Ramapo Town Code Chapter 354 designate specimen trees based on trunk diameter at breast height (DBH), typically 30 inches or greater, species rarity, or historical significance. Orangetown Code Chapter 21A and Haverstraw Chapter 116 apply similar standards. Heritage tree removal requires Planning Board site-plan review or Conservation Advisory Council (CAC) determination. NY ECL Article 9 provides state forestry framework, while Palisades Interstate Park Commission lands (Bear Mountain, Harriman) receive additional protection. Construction projects in Nyack, Piermont, and historic river villages require tree protection fencing at the critical root zone. Damage during development triggers restoration and civil penalties under Municipal Home Rule Law §10.

Violations & Fines

Unauthorized removal of designated heritage or specimen tree: $2,500 to $25,000 per tree plus replacement at appraised value (ISA trunk formula). Damage during construction in Clarkstown/Ramapo: $1,000 to $10,000 plus remediation. Repeat violations may trigger stop-work orders on entire site.

Frequently Asked Questions

Does Rockland County have a countywide heritage tree law?

No. Rockland County does not have a unified heritage tree ordinance. Each town (Clarkstown, Ramapo, Orangetown, Haverstraw, Stony Point, Nyack, Suffern) adopts its own tree preservation chapter. Check with your town's Building Department or Planning Department before removing any mature tree.

Are Palisades Park trees protected differently?

Yes. Trees on Palisades Interstate Park Commission land (Bear Mountain, Harriman State Park, Hook Mountain) are managed by the PIPC under NY State Parks regulations. Cutting, damaging, or removing vegetation on park land is prohibited under 9 NYCRR Part 375 and subject to state park police enforcement.
