NATURE: Monarch Butterflies at the Presidio

Thursday, Dec 14, 2017 Category Nature and Science

Western Monarch butterflies have begun their winter migration to Rob Hill Campground, one of 400 known “overwintering” sites in California (check out the Xerces Society website to learn more). Over the past 20 years, Monarch numbers have been low at Rob Hill; however, for the past two years, we’ve seen record numbers there with approximately 250 Monarchs spotted in 2016 and a count currently under way for winter 2017.

Recently, Presidio Trust Wildlife Ecologist Jonathan Young and local butterfly expert Liam O’Brien made a visit to Rob Hill to participate in this year’s Western Monarch Butterfly Count with the Xerces Society. Check out this brief video and learn more about these colorful creatures.
