Information Requests

Site and Corridor Information Requests

There has been no systematic survey for rare species across the state of Michigan. Species found near a project location may also be present in appropriate habitat at a project site. MNFI can only report on information that has been documented in the area. Therefore, searches based on a single site (TRS) are buffered out by four miles. That buffered area is then used to select records from the Natural Heritage Database for the information request list that will be provided.

Searches based on corridors may also be conducted, but are subject to a case by case evaluation by MNFI staff. Spatial data of the corridor is usually supplied by the requestor. Requestors will receive the standard information request report. A minimum of a mile wide search (half mile buffer) of a line corridor is applied to all corridor requests unless a larger buffer is requested. The area of the buffer is used to determine the data compilation fee.

Procedure for Making a Request

  1. Requestor sends a letter to the address below or preferably an e-mail to with the following information:
    • Name and address of the company, organization or individual making the request

    • Intended use of the information
    • Indication if a rush order is desired for an additional $100
  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 requestor. 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 the mail
  4. Upon receipt of the information service fee information will be sent by e-mail to the requestor
