Sheep Territory  February 24, 2012  Non-native mountain goats
have gained a foothold in parts of the greater Yellowstone
ecosystem and could threaten native bighorn sheep, including the

from Idaho, Montana and Wyoming have joined forces to study the
hardy, aggressive invaders, which have likely begun breeding in
the Teton Range.  "They don't get much attention," said Bob

Wildlife Ecology and Management Program, and leader of the

and spacial ecology can help inform management and

mountain goats and outfitting them with two different collars.
One collar contains a global positioning system device that
records the goat's position every six hours for two years. When
that falls off, another activates to give wildlife
