Monarch butterfly population recovery in Mexico, Digi Mart USA News (Mexico): The area occupied by monarch butterflies at their hibernation sites in Mexico grew 64% during the 2025-2026 season, rising from 1.79 to 2.93 hectares. With this result, the species has recorded two consecutive seasons of recovery.
Monitoring carried out by Semarnat, Conanp and WWF Mexico identified nine colonies: three in Michoacán and six in the State of Mexico. The largest was located in the El Rosario ejido in Michoacán, where it occupied 1.62 hectares.
Although the increase represents a favorable sign, the recorded area is still far below the historical maximum of 18.19 hectares, reached in the 1996-1997 season.
Among the conditions that favored this growth were rains and reduced drought in breeding areas and during migration, which allowed greater availability of nectar.
Despite the recovery, the species remains threatened by climate change, pesticide use and illegal logging, so its protection requires coordinated efforts among Mexico, the United States and Canada.
