Butterfly Pavilion, based in in Westminster, and the Government of Mexico have joined forces on new project aimed at restoring the wintering grounds of monarch butterflies in Mexico’s Butterfly Biosphere Reserve. The project was unveiled during a joint press conference at the Secretaría de Relaciones Exteriores in Mexico City.
The monarch butterfly, known for its migration of over 3,000 miles from Canada and the northern United States to Mexico, faces significant threats from climate change, deforestation and habitat loss. The population of overwintering monarchs has decreased by nearly 80% over the past 30 years. The Oyamel fir forest, which provides shelter for the butterflies, has lost over 95% of its original range.
“This project represents hope — for the Monarch butterfly and the ecosystems it helps sustain,” said Nathalie Brochu, Interim CEO of Butterfly Pavilion. “Restoring these vital habitats isn’t just about saving a species. It’s about ensuring that future generations can witness the wonder of the Monarch migration and the cultural and ecological richness it embodies.”
Supported by a grant from the Association of Zoos and Aquariums’ Conservation Grant Fund, the project aims to restore monarch habitats by replanting 100,000 native Oyamel fir trees in high-elevation areas. This effort is seen as critical to secure the future of the monarch migration.
The initiative involves collaboration among multiple organizations, including the Consulate General of Mexico in Denver, the Mexican Agency for International Development Cooperation, the Secretariat of Environment and Natural Resources, and the National Commission of Protected Natural Areas of Mexico.
“This project is a clear example of how international collaboration can generate tangible solutions to complex environmental problems. Together, we are building a more sustainable future for the monarch butterfly and the communities that depend on its migration,” said Dr. Pedro Álvarez Icaza, Head of CONANP.
Monarch butterflies are important pollinators and serve as indicators of environmental health. Their migration underscores broader ecological issues, making conservation efforts essential. Butterfly Pavilion’s project will also engage communities in the U.S. and Mexico through educational programs, including the creation of pollinator gardens.
Success for this initiative relies on meeting the goal of planting 100,000 trees, which will require additional funding. Last winter, monarch colonies occupied only 0.9 hectares of forest, the second-lowest figure on record. Experts indicate that a minimum of 6 hectares of suitable habitat is necessary for the species’ survival.
