A Keuka College biology major has turned her passion for science and illustration into a campaign against invasive species threatening the Keuka Lake Watershed.
Lily McLaughlin, a fourth-year student from Irondequoit, created a series of educational posters featuring ten of the most harmful invasive species in the region. Her goal: to help local residents identify and stop the spread of these ecological intruders.
“I knew there were a lot,” said Lily, describing the initial list she compiled for her self-directed Field Period® project, “but I didn’t know there were that many.” The final count topped 100 species.
Lily’s illustrated posters spotlight destructive plants and animals, including zebra mussels and purple loosestrife. The posters also offer tips for safe removal, like digging up loosestrife by the roots before it goes to seed.
“I hope that people who see my work will understand that invasive species can become a huge problem if they’re not managed properly,” she said.
Dr. Dominique Derminio, assistant professor of biology at Keuka College, explained that invasive species “can alter water quality and food web dynamics,” especially in freshwater ecosystems like the 174-square-mile Keuka Lake Watershed. Derminio noted that zebra mussels “contribute to ecological shifts that may exacerbate harmful algal blooms.”
Lily’s interest in invasive species grew after she worked with spotted lanternflies during an earlier Field Period. The insect, which first appeared in New York in 2020, has caused damage to local vineyards. A later course in limnology, the study of lakes, deepened her awareness of the issue.
Her project drew praise from faculty for its blend of research, outreach, and artistic expression. “By examining the invasive species in our region, students can gain hands-on experience in field research, data analysis, and environmental problem-solving,” said Dr. Derminio. “This prepares them for jobs in conservation, research, and policy.”
Lily, who chose Keuka College for its lakeside setting and small community, said the Field Period experience opened up new career possibilities.
“I hope this experience will guide me to start pursuing scientific illustration, or to continue to work with invasive species,” she said.
