RAPID CITY, S.D. (May 20, 2019) – Brady Neiles of South Dakota’s Game, Fish & Parks, has transformed the way wildlife populations are tracked. Using B9Creations 3D printing technology, Neiles created an expandable collar with a tracker – an alternative to surgical implantation, the only tracking method used on juvenile bobcats today. The potential extends far beyond, to population estimates on species, like fawn, throughout the United States.
