Autumn arrived Thursday, but the annual monarch butterfly migration during the fall season has been underway for more than a few weeks now and communities can help them on their journey. Cities across the Region and the country are invited to sign the Mayor’s Monarch Pledge to help protect endangered monarch butterflies. In June the National Wildlife Federation said it welcomed a record number of mayors and communities – 345 in total — to the program, setting a new milestone for the program. Through the pledge, cities commit to creating habitat for monarch butterflies and engaging residents in efforts to save monarch butterflies and other pollinators. The National Wildlife Federation says the number of monarchs has dropped by about 90-percent over the past several decades. Here’s a link for updates on this fall’s migration.
