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.
The abundance of monarchs shows a discouraging downward trend over the past 20+ years. Click on the graph to enlarge and on this link to read how the numbers were obtained.
In the Spotlight
With funding from MBF, the Monarch Butterfly Biosphere Reserve printed three large signs informing visitors to the butterfly colonies that the area that they are visiting is under restoration. These signs were placed in strategic areas in Sierra Chincua that were damaged by a storm in March, 2016 and where the Reserve is carrying out recovery and restoration work. Among the activities they are performing are reforestation, soil retention and perimeter fencing aimed at protecting the seedlings that were planted with the support of several institutions, ejidos and communities.
