Black-tailed Deer Study

Decemeber 22, 2013

This is year two of our black-tailed deer study in Western Oregon. The Oregon Department of Fish and Wildlife chose to study deer in four wildlife management units in western Oregon. The Indigo Unit is one of them and the goal is to radio collar 30 deer per year in randomly selected areas. Deer must be collared in a variety of landownerships: federal lands, large private, mixed private/public, & small private. The radio’s being utilized by the study are GPS radios which are programmed to collect a location waypoint every six hours for an average of 10 months. The collar also has a mortality sensor which gives off an alert for employees to retrieve the collar and determine cause of death or if there was a malfunction. These collars will provide a lot of information on deer movement and survival, more data than any other black-tailed deer study has produced before. The data will provide insight into what kind of habitat deer prefer, if they move seasonally, etc. Department personnel have been trying to capture these deer using a number of different methods. One method shown below, involves sitting in a tree stand with a dart gun over a bait pile.
