Monarch Butterfly

The Monarch Butterfly migrates 5000km+ every year from its wintering grounds in Mexico to its summering grounds in the US and Canada. Monarchs are considered an endangered species in Nova Scotia, and their population has been on the decline for decades; there are many contributing factors for this, most notably the widespread use of pesticides in land management, as well as the destruction of their habitat. Monarchs lay their eggs exclusively on milkweed plants: therefore, a lack of milkweed can be a limiting factor to the population growth of the monarch while here in Nova Scotia for the summer. MTRI's work is focused on the establishment of new milkweed habitat for monarchs on both public and private lands, educating the public on pollinator friendly and pesticide free gardening practices, and tracking Species at Risk sightings of monarchs. We have run the Butterfly Club for many years, which now has over 2000 members! If you are interested in becoming a member, please contact us at
