Monarch Butterflies Make An Amazing Rebound In 2021

Last Thanksgiving, many volunteers helped conduct a tally of overwintering monarch butterflies. Incredibly, the tally came to almost a quarter million, up from 2020’s all-time low of just 2,000.

Volunteers counted the butterflies at 283 different sites up and down the California coast. Some of the overwintering sites saw incredible amounts of monarchs, numbers that haven’t been seen since the early 2000s.

The numbers are still not where conservationists would like to see them, as the monarch population was in the low millions 40 years ago.
