California Sees Return of Monarch Butterflies After Record Low in 2020

California is seeing the return of monarch butterflies after a record-low population in 2020. An annual winter count by the Xerces [[ ZER-sees ]] Society last year saw fewer than two-thousand butterflies, which was a massive decline from the tens of thousands recorded in years previous. Experts say climate change and development of their habitats have decreased the size of the monarch butterfly population to a fraction of what it was 30 years ago. Most of their winter roosting sites are now concentrated on California’s central coast. However, Sarina Jepsen of the Xerces Society is optimistic about this year as an unofficial count has already recorded 50-thousand butterflies at overwintering sites.
