Western Monarch Butterfly Population Declines to Near Record Low | Xerces Society
Following efforts by hundreds of volunteers to count overwintering monarch butterflies in California, the 28th annual Western Monarch Count has reported a peak population of just 9,119 butterflies this winter. This is the second lowest overwintering population ever recorded since tracking began in 1997 and coincides with monarch butterflies being proposed for protection under the U.S. Endangered Species Act.| xerces.org
