SHERIDAN — A science lecture planned for Oct. 23 will focus on studying mule deer in upper Powder River country. The Upper Powder River mule deer herd outside of Buffalo and Kaycee has been declining since the early 2000s. Several management strategies have been implemented to bring population back without success. A multiyear research project is now underway to provide a better understanding of the herd.

Wildlife biologist Cheyenne Stewart will discuss the study’s early findings as well as how fifth-graders are using the data to answer their own questions.

The lecture is free and open to the public. It will take place at Mars Agriculture Center room 201 at Sheridan College.
