The latest survey of monarch butterfly habitat in Mexico is a testament to the power of conservation. The area of forest occupied by hibernating monarch butterflies in Mexico has increased by 144% in relation to last year’s survey—the biggest growth in the past 12 years. A new colony of monarchs was also found in the Nevado de Toluca, State of Mexico.

Because we can’t count butterflies individually, we instead measure the area of forest they occupy during hibernation to get a sense of the overall population. This year’s survey, conducted by WWF-Mexico and partners, found monarchs in 14.94 acres of forest, up from 6.12 acres at the same time last winter. Researchers found eight butterfly colonies in the Monarch Butterfly Biosphere Reserve and six colonies outside of it. The largest colony occupied just over six acres of forest.

Monarch butterflies travel close to 2,500 miles from Canada and the United States
