Decline of Monarch Butterfly Population Halts, WWF Reports on Mexican Forest Coverage.

Monarch Butterfly Situation in Mexico

According to Vox - Загальний: According to WWF Mexico, the decline in the number of monarch butterflies—the world’s largest butterfly population—has stopped, despite increasing threats. Each autumn, monarchs migrate to central Mexico, where during the winter of 2022, they covered approximately 7.2 acres of forest. This marks an increase compared to previous years: 4.4 acres in 2021 and 2.2 acres in 2020.

The average coverage area for monarchs over the first 10 years of monitoring is about 21 acres. Meanwhile, around 15 acres is considered a sustainable threshold for the population’s survival. Karen Oberhauser noted:

'We are in a period of relative stability where the population has stopped declining.'

Efforts to Protect Monarch Butterflies

The Biden administration has also taken steps to protect monarchs, proposing at the end of 2024 to list them as a threatened species. However, a final decision on this matter is not expected until September 2026. In turn, two environmental groups have sued the U.S. Fish and Wildlife Service, which, according to a spokesperson, 'continues to evaluate the monarch butterfly using the best available science.'

Thus, despite ongoing threats, the monarch butterfly population in Mexico shows signs of stability—a positive signal for ecological researchers and conservationists. Further actions to protect this species, including the Biden administration’s proposals, could significantly impact its future survival, though final decisions on the butterfly’s threat status remain pending. The situation requires careful monitoring and scientific analysis to ensure the long-term preservation of this remarkable population.
