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.

In the Spotlight

In late February 2014, MBF Board members, Lincoln Brower and Gail Morris traveled to México and visited reforestation sites and the monarch butterfly overwintering colonies. In Lincoln's words, "I visited several sites and witnessed two extremes: a mere vestige of the former grandeur in the Sierra Chincua colony on the one hand and a spectacularly active colony with millions of monarchs flying down in El Rosario (see video above)." Gail videotaped Lincoln explaining oriole predation in the colony:


Based on observations by MBF consultant, Dr. Pablo Jaramillo, MBF will support his research which will monitor regenerating saplings to evaluate the possibility of recommending natural regeneration of previously logged areas. Lincoln and Pablo discussed this possibility in meetings with Mexican government officials who requested input into the new management plan they are drafting. Pablo explains his observations below:
