[an error occurred while processing this directive]Monarch Butterfly Biosphere Reserve, Mexico[an error occurred while processing this directive][an error occurred while processing this directive] Monarch Butterfly Biosphere Reserve is a 56,259 hectare tract of mountain land in south to central Mexico that is today a World Heritage Site. The area is an important biosphere reserve protecting the habitat of the monarch butterfly.
One of the most amazing sights at the Monarch Butterfly Biosphere happen every autumn, when millions of monarch butterflies congregate in the area, clustering on the trees just as their leaves are turning orange. The butterflies overwinter in the biosphere reserve, in such huge numbers that they weigh down the branches.

By spring they were off again on their journey back to Eastern Canada. By then, four successive generations of monarch butterflies have been born and have died. Scientists do not fully understand how the new generation of butterflies return up north, considering they have never made the route before, but it is one of the mysteries of nature.
Protection to the habitat of the monarch butterflies began in the 1980s, when a series of presidential decrees were enacted. In 2000, the area was elevated to a biosphere reserve. The Monarch Butterfly Biosphere Reserve was inscribed as a World Heritage Site during the 32nd session of the World Heritage Committee in Quebec City, Canada, 2 - 10 July, 2008.

The Monarch Butterfly Biosphere Reserve represent one of the most dramatic manifestation of insect migration anywhere in the world. The biosphere reserve protects some 70% of the total overwintering population of the butterflies in the east.
The need to protect the Monarch Butterfly Biosphere Reserve is heightened by the increase in illegal logging that destroys the butterfly's habitat. Another concern is the visitor infrastructure to bring in more tourists to the area, to appreciate the phenomenon may also lead to an adverse impact on the butterflies. Due to this, the Monarch Butterfly Biosphere Reserve needs to put together a protection and management plan for the butterflies, that they may still be in great numbers in years to come.
