The Range-wide Indiana Bat and Northern Long-Eared Bat In-Lieu Fee Program provides a practical mitigation option for unavoidable adverse impacts to Indiana bats and northern long-eared bats from infrastructure projects covered by a U.S. Fish and Wildlife Service-approved biological opinion or Habitat Conservation Plan. There are 22 states where the range of the Indiana bat overlaps with the range of the northern long-eared bat. The total northern long-eared bat range covers an additional 14 states (see map). The U.S Fish and Wildlife Service and The Conservation Fund developed the program to serve as a national case study providing an innovative and ground-breaking mitigation alternative across the entire habitat range of an endangered species.

The Bat In-Lieu Fee program has created consistency in ESA Section 7 consultations for the two bat species across their ranges while reducing the time, cost, and workload associated with the process.


  • Creates consolidated landscape-level mitigation for multiple smaller impacts for bats
  • Meets mitigation obligation for users by simply writing a check
  • Agencies have a streamlined approach to mitigation with a focus on high-quality conservation projects for bats



Conservation: The Conservation Fund is actively identifying high quality conservation lands that can benefit the recovery of Indiana bats and northern long-eared bats. As The Conservation Fund pools payments from developers impacting Indiana bat and northern long-eared bat habitat, it works with project partners to acquire these properties. The Deutsch property is one such property in Missouri.


The Deutsch property was purchased by Great Rivers Land Trust using funds granted from the Bat In-Lieu Fee program account. Most of the 159-acre property is covered by a healthy hardwood forest with a mix of predominantly oaks and hickories in the hills of Lincoln County and is adjacent to several conserved properties. The dense forest cover provides suitable foraging habitat for bats and there are numerous dead trees and snags that provide roosting opportunities. The purchase of the targeted property eliminated the possibility of development and prevented the fragmentation of the larger surrounding landscape of nearly 2,000 acres. The Deutsch property and the surrounding area also contain karst geology with numerous sinkholes and caves providing potential winter hibernating habitat, and a neighboring property has a verified Indiana Bat roost.
