New Hampshire has no laws treating cactus removal like a felony, as cactuses aren’t native to its climate and face no special protections there. Instead, the state’s quirky property rules focus on wetlands, invasives, and endangered plants rather than common yard vegetation. Homeowners generally enjoy broad rights to manage their land, subject to environmental permits.​
Wetlands Vegetation Rules
Cutting plants in wetlands requires a DES permit to avoid fines, even on private property. Routine yard work outside protected areas stays unregulated.​
Protected and Invasive Plants
Endangered species like certain sedges or ferns can’t be harmed without permission. Prohibited invasives ban transport or sale, but removal from your yard is encouraged.​
Property Owner Rights
No broad bans exist on chopping trees or shrubs on private land, unlike Arizona’s cactus statutes. Local zoning or HOA rules may add limits, so check town ordinances.
