Monarch butterflies (Danaus plexippus plexippus) are perhaps the most well-known and beloved butterfly species in North America. Their renowned long-distance, seasonal migration and spectacular winter gatherings in Mexico and California have heralded the transition from fall to winter for thousands of years.
Both the eastern and western migrations have experienced significant decline in recent decades. In the 1990s, nearly 700 million monarchs made the epic flight each fall from the northern plains of the U.S. and Canada to the Oyamel Fir Forests north of Mexico City. Now, researchers and citizen scientists estimate that there has been a decline of more than 80% in the east. In the west, the news is more dire. Monarchs have experienced a decline of 99.4% in coastal California, from an estimated 4.5 million in the 1980s to 28,429 as of January 2019.
Join us for a screening of The Guardians, a visually dazzling documentary about the delicate balance between humans and nature which interweaves the lives of the iconic Monarch Butterfly with an indigenous community in Mexico.
The screening will be followed by a discussion and Q+A with Bay Area monarch butterfly experts Mia Monroe, National Park Service ranger, and Liam O’Brien, author of the Butterflies of San Francisco.
