In Arizona and the surrounding Southwestern United States, over 400 people are participating in a nine-year ongoing game of tag. But these folks are not tagging each other. They’re actually romping about in meadows with small nets, hoping to catch and tag a Monarch butterfly. In 2003 Chris Kline began the Southwest Monarch Study in order to track the migration pattern of the Monarchs that appear in Arizona. Much was known about the migration of Monarchs down the eastern coast to Mexico, but this was not enough. Kline rallied Arizona locals to achieve mass data collection across the state, uncovering information about the unique Monarch population. Gail Morris is the current project leader of the Southwest Monarch Study and she radiates a passion for Monarchs. She sees beauty beyond the surface of their iridescent wings. Gail says that “it’s their incredibly long migration that gets me most excited.” She explains how wildly adaptable they are, as they use adverse weather conditions to their advantage. These little, thin winged creatures use Arizona’s annual monsoon to take flight thousands of feet into the air and fly fifty to one hundred miles a day. They can use columns of warm rising air called 'thermals' for travel. Once, after a day of meadow-romping, Gail was chatting with a friend by their cars: “This monarch shot up from a tree at angle like a plane ascending.” They marveled as it it joined a cast of hawks in a thermal and disappeared into the sky. So where are these butterflies going when they catch a ride in the wind? According to the Southwest Monarch study, it depends. Arizona Monarchs have a unique travel agenda, and it even varies from day to day. Monarchs comfortably take the wind as it blows, following it to specific overwintering locations in either California or Mexico depending on how the wind presents itself on the day they take flight. These locations can be as specific as a single tree, flocked to year after year. Some Monarchs even stay in Arizona through the winter, merely migrating to lower altitudes. All of this raw data was gathered by the locals, and analyzed by professional scientists. “The local people often see the movement but it had never been published,” Gail says. A while back Gail was searching for Monarchs with a group of citizen scientists in Northern Arizona. “These bird watchers heard we were looking for orange butterflies and they said ‘Stop at the fishery, you’ll find them there’”. This did not align with Gail’s previous knowledge about Monarch habitats, but she hesitantly followed her own mantra: the locals know best. When the group arrived at the fishery they were surrounded by walnut trees and these trees were showered in Monarchs. Gail was struck yet again by the Monarch’s adaptability to variable habitats. Lisa Rensch also finds her free time best spent chasing butterflies. She’s a prominent citizen scientist with the study, as she has been tagging with her daughter since 2013. Her daughter, only one year old when they began, learned to delicately handle the butterflies. Lisa is a true nature lover, completely losing track of time as she tracks the Monarchs. While tagging she has run into goldfinches and even "a nest of deer mice," she says. "It was lined with thistle down, the babies all snuggled cozy inside.” She never knows what she’ll find while searching for Monarchs. Currently the Southwest Monarch study is expanding. Groups in California, Utah, and Colorado are now tagging. As science often goes, the findings of the Southwest Monarch study have led not only to answers, but to further questions about these resilient creatures. Ultimately, the study hopes to further encourage conservation. Families and public areas are already inspired by the project, filling in the missing link to Monarch survival: rich sources of nectar for the butterflies to feed on. Southwest Monarch Study is teaming up with the city of Mesa, Tanto National forest, the Nature Conservatory, and the Bureau of Land Management, where each organization is adding milkweed to their property as a nectar source to support feeding of the Monarchs. Milkweed is a rich nectar source for other pollinators as well, so other animals will benefit a side effect. If you are wowed by these little troopers and live in the Southwestern United States, check out the Southwest Monarch Study. Find caterpillars, tag butterflies, plant milkweed and watch your garden come alive. If you are elsewhere, keep learning about these fascinating creatures by checking out this video, or learning about the findings from the study. Knowledge breads conservation; discovering how cool science is breads passion.
