NHB DataCheck Tool:  Introduction

The NH Natural Heritage Bureau (NHB) maintains data on known locations of rare species and exemplary natural communities.  The NHB DataCheck Tool allows anyone planning a project in New Hampshire that requires a permit to find out if there are NHB records in the vicinity of the project.

For questions about rare species in NH that are not related to a permit application, call NHB at (603) 271-2214 or send an e-mail to

The NHB DataCheck Tool was developed as a collaborative effort between the NHB, the Department of Environmental Services (DES), and the NH Fish and Game Department.

This web site is hosted by DES. However, the Tool can be used to comply with requirements by other agencies or organizations, when applicants must check for possible impacts on rare species or natural communities.

ATTENTION: Fixes for problems you may have using this online tool

What internet browser are you using?
Many users have reported problems when using Google Chrome. Try using another browser (e.g., Mozilla Firefox or Microsoft Internet Explorer).

If your operating system is Windows 7 or Windows 8, you may get a blank screen when you try to map your project. A solution is outlined below:

  1. Right-click on your computer's desktop. ("desktop" = your screen when all programs are closed or minimized. If using Windows 8, be sure to use Desktop setting.)
  2. From the drop-down menu that pops up, click on Screen Resolution.
    Note the current values so that you can reset it when done with the DataCheck Tool.
    • Click on "Make text and other items larger or smaller";
    • Select "medium" (your computer may tell you to restart to apply changes).

    This usually works. But if you still have map problems, repeat Step 1. After clicking on Screen Resolution, click on the Resolution drop-down and use the slider to reduce the resolution a step or two.

    Be sure to click on Apply and Keep Changes (if you have these options).
