Monarch Butterfly Biosphere Reserve

The Monarch Butterfly Biosphere Reserve, located in Mexico, protects crucial overwintering habitats for the North American monarch butterfly. Every fall, millions of these butterflies migrate from the United States and Canada to this area, clustering on oyamel fir trees to survive the winter. The reserve conserves these forests to ensure the butterflies have a safe place to rest and reproduce. This unique migration and hibernation process is vital for the species' survival, making the reserve an important effort in conserving biodiversity and ecological health across North America.
