There are not many insects as well-known, and as well-loved, as the monarch butterfly. Monarchs are characterized by their beautiful bright colors and their awe-inspiring migration. 

Unfortunately, monarch populations have been in decline for many years — but have you ever wondered how we know that? Tracking and estimating the population of any animal is tricky, even big ones like bears and eagles. How do you do it for an insect that moves across North America? 

Today, to help answer these questions, we are joined by Isis Howard, Endangered Species Conservation Biologist with the Xerces Society. Isis works to protect the monarch butterfly in the western states and manages several community science projects, including the annual Western Monarch Thanksgiving Count, New Year's Count, and the Western Monarch Milkweed Mapper.
