2021 International Monarch Monitoring Blitz
Journey North is a partner of the 5th International Monarch Monitoring Blitz!
From July 23–August 1, join thousands of volunteers across North America to look for monarchs and milkweed. Every observation shared with Journey North helps the scientific community conserve the monarch butterfly along its migratory routes. This information will help researchers identify priority areas for monarch conservation actions. Data gathered during the Blitz is uploaded to the Trinational Monarch Knowledge Network, where it is accessible for anyone to consult and download.
