NHB Environmental Review – DataCheck Tool

Information About Rare Species for a Permit or Grant Requirement

NH Heritage maintains a database of known locations of rare species and exemplary natural communities. Federal, state, and local agencies may require a check of this database to determine whether a proposed project could impact rare species or critical habitat. In some circumstances, a $25 fee will be assessed to cover staff time.


There are two ways to request a check of the NH Heritage database:

1. Use the DataCheck Tool. This is an interactive web page that can be used to provide NH Heritage with basic information about a project, including a map.

If there are no NH Heritage records anywhere in the vicinity, a letter to that effect will be e-mailed at once, automatically, and there is no fee. If NH Heritage records are in the vicinity, a review by NH Heritage is needed. This review can be requested using the DataCheck Tool. If the $25 fee is required it must be paid by check or money order.

First Time Users: Please print instructions for mapping your project using the Tool.
2. Submit a request form to NH Heritage by e-mail or mail.

Landowner Requests (including forest management plans) 

NH Heritage can check its database to see if we have any rare plant, rare animal, or exemplary natural community records on your property. Please fill out the landowner request form to request such a check. There is no fee for this service. However, the results cannot be used for permit requirements (the scope of the database check is different). See above to request information for a permit requirement.

Please note that very little of New Hampshire has been inventoried for biodiversity, so even if something is on your property, it has probably not been recorded. A field survey would provide better information on what species and communities are indeed present. NH Heritage is sometimes able to do property-specific inventories for towns or individuals, but only after we have worked out a formal contract to cover our expenses.
