Join the “Monarch mission” on Mount Royal!


On August 26, Les amis de la montagne’s conservation team invites you to join them in Mount Royal Park for a blitz census of the monarch butterfly population for a second year in a row.

To assist in the protection of the monarch and the development of a national conservation plan for this species, the Montréal Insectarium and different Canadian universities have launched the “Monarch Mission”, which invites the public to take part in an inventory of monarch eggs and caterpillars on their host plant, the milkweed.

Les amis de la montagne has decided to join forces with the Insectarium to get an accurate picture of the monarch breeding sites in Mount Royal Park and we need your help to accomplish this mission! Help us collect data which will help research on this species of butterflies, considering its populations in Canada have declined by 90 % in the last 20 years.

On August 26, at 10 a.m. and again at 1:30 p.m. at Smith House, Les amis’ team of biologists will welcome all citizens who wish to participate in this blitz census and accompany them every step of the way.

This is a great opportunity to enjoy summer and nature with family or friends, while contributing to preserving biodiversity and helping save a beautiful species of butterflies!

Please note the activity will be held in French.
