Mitigating New Threats to Bighorn Sheep

Wednesday, April 23rd, 2014

In 1969, mountain goats were introduced in Idaho and have since expanded into Grand Teton. They now threaten Teton Range bighorn sheep, a native herd whose protection is one of Wyoming’s and the park’s highest conservation priorities. If left unchecked, a robust population of invasive mountain goats could rapidly transform Teton flora and fauna forever.Park staff is initiating new research and monitoring to implement goat management strategies to protect native bighorn sheep and ecosystem function.
