Robert Hess

Wisconsin DNR - KBB Recovery Coordinator on State lands


Karner blue butterfly research/management work:

Position is responsible for organizing and implementing a recovery program on Wisconsin DNR properties for the Karner blue butterfly (Kbb).


We are using Distance methodology to estimate Kbb population sizes on recovery sites designated in the national Kbb Recovery Plan.


Working with the cooperation of the Wisconsin Habitat Conservation Plan partnership for the Kbb, we are also developing an emergence model to facilitate Kbb population monitoring and assessment.


All of this work is being done to achieve recovery goals for the Kbb that are identified for Wisconsin in the Kbb Recovery Plan. Initial population and habitat assessment is scheduled to begin with the first Kbb flight in 2008.



Developed a habitat assessment method and protocol to identify the characteristics of habitat suitable for the Kbb.
