What is the monarch tagging program?

The Monarch Watch Tagging Program is a large-scale community science project that was initiated in 1992 to help understand the dynamics of the monarch’s spectacular fall migration through mark and recapture. Tagging helps answer questions about the origins of monarchs that reach Mexico, the timing and pace of the migration, mortality during the migration, and changes in geographic distribution. It also shows that the probability of reaching Mexico is related to geographic location, size of the butterfly, and the date (particularly as this relates to the migration window for a given location).
