Western Monarch butterfly abundance at 149 overwintering sites in California, 2017-2021. These critically low numbers follow two years with fewer than 30,000 butterflies—the previous record lows, indicating that the western monarch butterfly migration is nearing collapse. Sites were visited during both the Thanksgiving and New Year’s Counts during the 2020–2021 count season. Graphic: Xerces Society

Forest degradation in the Monarch Butterfly Biosphere Reserve core area, 2002-2020. The presence of the Monarch butterfly in the Mexican hibernation forests decreased by 26 percent last December, occupying 2.10 hectares (ha) compared to the 2.83 hectares reported during the same month in 2019. Meanwhile, the core forest area in the Monarch Butterfly Biosphere Reserve (MBBR) where the lepidopteran establishes the main hibernation colonies recorded, between March 2019 and March 2020, 20.26 ha of degradation, four times more than in 2018-2019 when 5 ha were degraded.
