Do Not Reopen Mine in Prime Monarch Butterfly Habitat

Target: Fausto Vallejo Figueroa, Governor of Michoacan, Mexico

Goal: Stop plans to reopen a copper mine in the heart of Monarch butterfly territory.

Plans have been announced to reopen a dormant copper mine that lies in the middle of Mexico’s Monarch Butterfly Biosphere Reserve. The endangered migratory butterfly finds shelter here during the cold winter months. If this space becomes contaminated, the species, which is already facing extinction, could be placed in further peril.

The mine, which closed 25 years ago, has already made a detrimental impact on the area around it. A flood in 2010 carried various heavy metals, including arsenic, bromine, lead, barium, cadmium, chrome and mercury, from the mine into nearby rivers and water sources. The water used in the mining process will be drawn from local springs, potentially drying them out and leaving nearby flora and fauna without adequate water.

Monarch butterflies are an endangered species that could become extinct within 20 years. Habitat destruction, changing weather patterns, a massive increase in the use of herbicides and pesticides, as well as the loss of milkweed has caused a population decline of almost 100 million since 1990. To open a mine in a major butterfly habitat would be to ignore the proven effects of human development on butterflies in the past.

Monarchs are an iconic pollinator species and one of the most recognizable North American butterfly species. In order to save them from extinction, it is imperative that everyone does their part in conservation. Sign the petition below to demand that the reopening of Grupo Mexico’s copper mine is halted immediately.


Dear Governor Figueroa,

A mining company has announced plans to reopen a copper mine in the heart of the oyamel fir forests, a major habitat for the migratory Monarch butterfly. Opening this mine could reduce available resources for flora and fauna in the area, as well as contaminate soil and water with heavy metals. This project could be detrimental to the already-struggling butterfly species, which has seen a population decline of nearly 100 million since 1990.

These butterflies are an iconic pollinator species, and are at serious risk of going extinct within the next two decades. In order to save them, it is imperative that we leave their habitats as untouched as possible. We, the undersigned, urge you to halt the reopening of Grupo Mexico’s copper mine in order to preserve essential Monarch butterfly habitat.

    Monarch butterflies have recently suffered a precipitous decline. These butterflies are truly endangered, and it would be the height of irresponsibility to even consider opening a mine in its prime habitiat!
