People relocated around 375 mountain goats from one national park to another by using a helicopter. This happened in Washington which is a US state on the West Coast bordering with Canada.

The Olympic National Park and the North Cascades National Park are around 200 miles apart by road in the same state.

The goats are native to the Cascades, and people intended the move to protect natural resources in the Olympic National Park and to improve visitor safety. The goats ate and trampled sensitive vegetation, and disturbed soil when they wallowed. In 2010, an aggressive goat fatally charged at a hiker on a popular trail.

Difficult words: intend (plan to do something), trample (step on, walk over and crush), vegetation(plants), disturb (make a mess of), wallow (lie or roll on the ground), fatally (with death as a result), trail (a path, a way).
