The Monarch Butterfly Biosphere, a UNESCO World Heritage site in Mexico, serves as a critical wintering ground for millions of monarch butterflies migrating from North America. This unique ecological sanctuary, recognized for its outstanding universal value, protects the butterflies' overwintering habitat within a network of oyamel fir forests. The site showcases a remarkable natural phenomenon, where dense clusters of butterflies blanket the trees, creating a stunning display of orange and black. Conservation efforts here focus on preserving this vital ecosystem amid threats like climate change and habitat loss.
