Rare Species Reviews

The Rare Species Review provides a desktop-level of information on the rare species in the immediate vicinity of your project. Once project information is provided, MNFI uses the database to evaluate potential impacts to rare species that are known to be near the project. Results are compiled in a letter listing all species within the area and MNFI’s evaluation on the potential impacts the project may have on those species.

This level of review corresponds to the Endangered Species Assessment previously provided by the Wildlife Division of the MDNR. The MNFI letter can be submitted for consideration when working with the State of Michigan.

This is a desktop review based on the MNFI natural heritage database. While we may be able to determine if there will be potential impacts to a rare species, MNFI cannot supply a "no impact" designation without an on site assessment.

Information Provided with a Review Letter

No Species Present Letter

  • A letter stating that there are no known species currently present based on the Natural Heritage Database. Absence of evidence is not evidence of absence. A comprehensive survey of the entire state has not been done so MNFI can not state that no species exists at any location.

Species Present Letter

  • Letter listing out ALL species that are located in the area of the project.
  • Specific management recommendations and highlighting of those species that are considered to have potential impact by project activities.
  • A listing of all State and/or Federal regulations that the requestor needs to be aware of.
  • Recommendations if MNFI science staff evaluate a project as needing more intensive review such as a field survey.

Optional Informaton

Available at an additional cost.

Map of Project Area

A footprint of your project area will be displayed along with Eastern Massasauga Rattlesnake Tier 1 and Tier 2 habitat boundaries, Michigan Freshwater Mussel Stream Designations, high quality communities, critical habitats, critical dunes, high risk erosion areas and any designated wetlands that are present near your project.

Spatial Data for Project Area

Spatial information within 2 kilometers of your project will be selected and compiled within a geodatabase. The Eastern Massasauga Rattlesnake Tier 1 and Tier 2 habitat and the Michigan Freshwater Mussel Stream Designations will be included.

Procedure for Making a Request

  1. Requester sends an e-mail to mnfi@msu.edu or requester sends a letter to our mailing address with the following information:

    • Name and address of the company, organization or individual making the request
    • Brief description of the proposed project
    • Description of what is there now (building, type of vegetation, recent disturbance)
    • Location of the area to be searched listed by PLSS town, range and section
    • Indication if a rush order is desired for an additional $100
    • Selection of additional options such as printed map or spatial data for an additional $50 each
  2. MNFI staff will respond to the e-mail by sending an information services agreement.
  3. Once the signed information services agreement has been returned to MNFI a search will be performed and an invoice will be generated and sent to the requester. In the case of a rush order information on the location will be sent and it will be assumed that the fees will be sent in.
  4. Upon receipt of the information service fee information will be sent by e-mail to the requester.
