Mexican officials and environmental groups say the number of monarch butterflies that hibernate in the country rebounded this year.
The area of land covered by hibernating monarch butterflies in Mexico this year almost doubled compared to last winter.
Monarch butterflies are under pressure from a changing climate and habitat loss. Experts say the past year’s population increase is thanks to more favorable weather conditions — specifically, less intense drought on the butterflies’ route from Canada and the U.S. to Mexico.
The rebound is just a sliver of what was seen there in the 1990s, when scientists in Mexico started estimating the size of the winter population. Experts say the number remains far below the long-term average.
The U.S. Fish and Wildlife Service late last year proposed protecting monarch butterflies under endangered species status.
