The NH Natural Heritage Bureau finds, tracks, and facilitates the protection of New Hampshire's rare plants and exemplary natural communities (types of forests, wetlands, grasslands, etc.). As a bureau within the Division of Forests & Lands, we are fundamentally a service to New Hampshire landowners and land managers. We are not a regulatory agency; instead, we work with landowners and land managers to help them protect the State's natural heritage while meeting their land-use needs.
Our mission, as mandated by the Native Plant Protection Act of 1987 (RSA 217-A), is to determine protective measures and requirements necessary for the survival of native plant species in the state, to investigate the condition and degree of rarity of plant species, and to distribute information regarding the condition and protection of these species and their habitats. We also maintain information on rare wildlife in cooperation with the NH Fish & Game Department's Nongame & Endangered Wildlife Program, which has legal jurisdiction over New Hampshire wildlife. Visit our About Us page for more information about our organizational structure.
What's Rare in New Hampshire?
Please note that NHB's Environmental Reviewer will be out of the office between July 3 and July 14, and unable to respond to questions.
During this time, the Datacheck tool will still be available. Projects that do not require additional review will still receive the automatic “no known records” response letter from the Datacheck website.
For projects that do come up on the Datacheck tool as having potential impacts, those projects submitted between July 3 and July 14 will be reviewed during the week of July 17.
We apologize for any inconvenience, and thank you for your understanding.
