Collaring Elk


Since 2005, the National Elk Refuge and Wyoming Game & Fish Department have deployed 88 collars on elk wintering on the refuge.

Biologists initially used VHF radio collars, which emit a unique signal that can be picked up by a transceiver. Beginning in 2008, biologists began using GPS units, devices which use satellites to give a more precise location than the VHF units.

Elk location data collected from the collars will help wildlife managers map elk movement and habitat use, design hunting seasons to meet objectives, monitor the effects of wolves on elk density, and evaluate the effects of elk density on potential disease transmission.

The refuge's photo gallery includes a series of pictures that chronicle biologists collaring elk on the National Elk Refuge. When viewed in order, the pictures take the viewer through the collaring process from start to finish. The collaring is part of a cooperative research project that evaluates habitat use and elk distribution.
