The current and future distribution of armadillos: constraints, implications, and management

October 2021 - October 2027


Participating Agencies

Nine-banded armadillos (Dasypus novemcinctus) are rapidly expanding their range within the United States, at least partially facilitated by climate change. It is currently unclear how much of the northern United States they can colonize and even less clear what the implications of their arrival are for native wildlife. Armadillos are ecosystem engineers that cause extensive alteration to their environment through their prolific burrowing behavior. These alterations are certain to change the availability of shelter sites, thermal environment availability, and predator-prey interactions of native wildlife and yet there is no research to explore these changes. Working with faculty and students at the University of Arkansas, Michigan State University, Bradley University, and the Michigan DNR, the Michigan Unit is exploring some facets of the distribution of armadillos and the repercussions for native wildlife. Understand the limits of armadillo range expansion will allow managers to pro-actively inform the public about management strategies to reduce conflict with humans as well as to better understand the implications for native wildlife that may soon be co-existing with armadillos.
