During the 2021-2022 overwintering season, 10 colonies of Monarch Butterflies covered 2.835 hectares (ha) of forest, which represents a 35% increase from 2020 (2.10 ha). Because it is impossible to count each butterfly, a survey is conducted to measure the area of forest the monarchs occupy each winter in their hibernation colonies, in Mexico, providing an indicator of their population status.

February 7, 2022– The U.S. Fish and Wildlife Service has completed 90-day findings on petitions to list three species under the Endangered Species Act (ESA). Based on our review, the Service finds that the petitions to list the thick-leaf bladderpod and variable cuckoo bumble bee present substantial information that the petitioned actions may be warranted, and we will initiate status reviews for these species.
