The Blitz results at a glance!

Between July 28 and August 5, everyone in Canada, the United States and Mexico was invited to take part in an International Monarch Monitoring Blitz to collect data on monarch butterflies. And what is really great is that the results are already available online, with an interactive map showing the exact location of monarch reproduction sites in the three countries, at a glance.

All in all, 486 people took part in the Blitz in 7 Canadian provinces, 16 Mexican states and 36 US states. A total of 53,588 milkweed plants were examined and 13,831 monarchs sighted. And we’re pleased to note that Canadians made a huge contribution. You can see the results in your region by clicking on the orange dots on the map.

This international Blitz is part of the Mission Monarch research project, which aims to save monarch butterflies with the help of the public. The data gathered will be used to give scientists a snapshot of the status of monarch populations all along their migratory corridor.

And even though the Blitz is over, Mission Monarch still needs your help! You can continue contributing data until mid-September, when the last monarchs usually leave the region for their long journey to Mexico.

For detailed results, see the press release from the Commission for Environmental Cooperation.
