MaryAnn Lepp was delighted to observe an abundance of monarchs undergoing their transformative journey in her garden, with 20 caterpillars feasting on her swamp milkweed within a single day this week. This surge in backyard milkweed patches across parts of the Prairie has captured the attention of numerous Canadian monarch enthusiasts.
Expressing her excitement, Lepp in La Broquerie, located around 60 kilometers southeast of Winnipeg, eagerly scanned her garden for monarch cocoons. She noted an increase in butterfly sightings compared to previous years.
While the precise cause of this phenomenon remains uncertain, conservation experts are encouraged by the surge in reports of caterpillars, chrysalises, and monarch butterflies. This surge is particularly significant for the federally endangered species known for its remarkable annual migration between Canada and Mexico.
Marika Olynyk, curator of the Living Prairie Museum, remarked on the abundant presence of monarchs in Winnipeg this year, highlighting a consistent presence of caterpillars, chrysalises, and butterflies throughout the summer.
Despite the efforts of individuals like Lepp in planting milkweed and native wildflowers, these essential habitats are not as widespread as they once were due to the conversion of native grasslands into farmland. Habitat loss remains a significant threat to monarch populations, emphasizing the urgent need for conservation measures.
The status of monarchs was elevated from “special concern” to “endangered” in 2016 by the Committee on the Status of Endangered Wildlife in Canada. It wasn’t until December 2023 that the federal government followed suit, implementing legal protections to prevent harm or capture of monarchs on federal lands at any stage of development.
With the population of monarchs currently at only 50% of sustainability, conservation efforts remain crucial. Laura Burns, conservation programs manager at the Assiniboine Park Zoo, noted an increase in monarch numbers at the native prairie garden, alongside efforts to support the critically endangered Poweshiek skipperling butterfly.
The zoo’s breeding and release program for the Poweshiek skipperling has shown promising results this summer, indicating a positive trajectory for the species. These conservation efforts, along with favorable weather conditions, offer hope for the recovery of butterfly populations.
Looking ahead, the zoo plans to equip monarchs with radio transmitters this fall as part of a project to track their migration to Mexico. Enthusiasts like Lepp continue to play a vital role in safeguarding caterpillars and chrysalises, emphasizing the importance of preserving nature and fostering a connection with the environment.
