Each fall the monarch butterfly travels thousands of miles to spend the winter in the forests on 12 mountaintops in central Mexico. The monarch migration is the most spectacular two-way migration carried out by an insect.

The forests provide unique microclimatic conditions that allow monarchs to survive the winter. Forest degradation is putting this amazing migration in peril.
