Every fall, hundreds of millions of monarch butterflies make their way from the United States and Canada to overwintering sites in Mexico. In recent years, this phenomenal migration is threatened by habitat loss in North America and at their overwintering grounds, so people across the continent have been setting up monarch way stations to help protect this species.
Last fall, Carolyn Mahan, professor of biology and environmental studies at Penn State Altoona, took students in her Ecology of the Mid-Atlantic course to Penn State DuBois to explore one such station created there in 2015. Led by Senior Instructor in Wildlife Technology Keely Roen, the station at Penn State DuBios is modeled after Monarch Watch, established at the University of Kansas in 1992. Monarch Watch is a conservation research program that focuses on the monarch butterfly and how to protect its migration.
Roen explains that several years ago the situation for monarchs looked dire. Eastern monarch numbers had declined approximately 90 percent in just two decades. The overwintering population in Mexico, which pretty much contains every monarch from the eastern United States and Canada, covered only about 1.7 acres during the winter of 2013. "We are losing monarchs because of destruction of their winter habitat in Mexico and the loss of milkweed in the U.S. It could also be the overuse of herbicides and insecticides and extreme weather from climate change. The good news is there are many efforts going on to restore and plant milkweed and nectar plants for the adults. More and more people are starting to plant these in their gardens and raise monarchs. Last winter the eastern monarch population covered over six acres and this summer had one of the most impressive migrations I have seen in a decade. I am cautiously optimistic that these efforts may be making a difference."
Now, some Penn State Altoona students are doing their part to contribute. After visiting Penn State DuBois, Traci Cobb Irvin, a 2017 biology graduate, initiated a rearing program at Altoona and registered the Penn State Altoona campus with Monarch Watch. This year, current environmental studies students Michelle Smithbauer and Nathan White have continued Cobb Irvin’s work. A small Student Engagement Network grant helps pay for supplies such as jars and string, but Smithbauer and White collect milkweed and care for the caterpillars and butterflies on their own time.
