Welcome to the Maine Natural Areas Program Data Checker. The Data Checker allows you to determine if your forestry activities intersect with rare plants, rare animals, rare/exemplary natural communities, significant wildlife habitats, or essential wildlife habitats in Maine.

This is a non-regulatory tool intended to help foresters and landowners acquire information relevant for timber harvest reviews, forest management planning, forestry cost-share practices, forest certification, or related purposes. This is not a permitting tool. For inquiries regarding development or forestry permitting, please follow standard permitting procedures by contacting the Department of Environmental Protection (, the Land Use Planning Commission (, the Maine Forest Service (, or other permitting authorities.

The Maine Natural Areas Program (MNAP) maintains mapped information on rare species and rare and exemplary natural communities, and the Maine Department of Inland Fisheries and Wildlife (MDIFW) maintains mapped information on rare animals and significant and essential wildlife habitats. The Data Checker enables inquiries on behalf of landowners or their designated agents regarding MNAP and MDIFW records in the vicinity of specific properties.

For questions regarding the Data Checker, please contact MNAP at (207) 287-8044 or send an e-mail to

What can you get by using the Data Checker? (scroll down)

  • You will receive an automatic confirmation if there are no mapped MNAP or MDIFW features in the vicinity of your project area. The confirmation will indicate only MNAP features, but MDIFW features are included in the Data Checker.
  • If features are found in the vicinity of your project area, you will be guided on how to contact MNAP for further information on the features and management considerations for them. The response will indicate only MNAP features, but MDIFW features are included in the Data Checker. This follow-up, on your part, is voluntary.

What CAN'T you get by using the Data Checker?

  • Although you can use the tool to find out if there are MNAP/MDIFW features in the vicinity of a property, you cannot accurately determine the location of the features or the specific feature itself. The Data Checker looks for potential overlap to MNAP/MDIFW features.
  • The tool does not provide any information about what kind of features might be in an area. You will need to contact MNAP for more information on the feature when an overlap is detected.
  • The Data Checker does not include screening for data from the US Fish and Wildlife Service (specifically, Canada lynx and Atlantic salmon). For more information about Atlantic salmon in Maine, please visit and For more information about Canada lynx in Maine, please visit and
  • Wild brook trout data are not included in this screening. You should assume that all cold-water streams in Maine have the potential to support wild brook trout, and all Best Management Practices should be followed, including appropriate buffer distances, shade retention, and minimization of sediment runoff. For forest management recommendations for brook trout, please visit or contact MDIFW at 287-8000.
  • If there are MNAP/MDIFW features in the vicinity, you cannot get a definitive statement of whether your project will actually impact rare species or natural communities. The Data Checker collects some information about each project, but more project details (e.g., site plans) or a site visit may be needed to assess impacts. Please follow up with MNAP (see below).

What information do you need to have to use this site?

  • The specific location (polygon) of the area you are interested in.
  • The name, address, and contact information of the landowner and confirmation that the landowner agrees to the request for information.
  • If the requestor is not the landowner, the name, address, and contact information of the person requesting the information on behalf of the landowner.
  • The type of project for which this information will be used.
  • If a follow-up inquiry to MNAP is recommended, please submit a map and brief project description to
    • MNAP at or via hard copy to Information Manager, MNAP, 93 State House Station, Augusta, ME 04333
