Results suggest we need to continue our efforts to conserve this species
MONTREAL, Sept. 30, 2020 /CNW Telbec/ -The Commission for Environmental Cooperation is pleased to announce the results of the fourth International Monarch Monitoring Blitz. Between July 24 and August, 2, 520 volunteers across 68 states and provinces participated in the Blitz. They recorded 9,649 monarchs at various stages of their life cycle, from eggs to butterflies. And together, they monitored 40,321 milkweed plants, the sole food source for monarch caterpillars.
"This year's Blitz is a great example of how people all across North America are taking the monarch situation seriously", said Alessandro Dieni, Mission Monarch Coordinator at one of the organizations leading this initiative, the Insectarium | Montréal Space for Life.
For one week, over five hundred volunteers in Canada, Mexico and the United States helped monarch experts gain more information to enable better understanding of the distribution of the migratory monarch butterfly, an emblematic North American species.
"Even though there were many challenges this year, people managed to help the scientific community gather more data on monarchs and milkweeds. It is inspiring to see how people care about the monarch's wellbeing, and how they mobilize themselves to be part of its conservation," added Dieni.
The information collected will help researchers identify priority areas for monarch conservation actions. The data gathered are accessible for anyone to consult and download on the Trinational Monarch Knowledge Network.
Importantly, results suggest that the monarch summer population is smaller than last year. In 2019, there were approximately 24 caterpillars per 100 milkweed plants inspected across North America - three times higher than this year's 8 caterpillars per 100 milkweed plants inspected. These results sadly parallel the observed decline of the overwintering population measured last winter in Mexico.
This year was particularly notable because volunteers surveyed more milkweed per person than in previous years. We thank our dedicated volunteers who do incredible work for the protection of monarchs and milkweeds. Indeed, the higher ratio of observations per participants is not the only highlight of this 2020 Blitz: in Mexico, we saw more participants and observations of milkweed and monarch than ever before.
Efforts must continue to create and protect the monarch's habitat and actively participate in citizen science programs like the Blitz. The North American monarch butterfly is an iconic and fascinating species that still needs our help.
