A Beautiful Day for Service Learning

Every fall Biology 250 students engage in a service-learning project. This past Thursday their assignment was to clear loosestrife, a nonnative invasive species, from the area surrounding the parking-lot pond. “This project allows students to learn firsthand how persistent purple loosestrife and other nonnative invasive species can be,” states Dr. Ming Zheng, professor of biology.
In this photo Dr. Zheng demonstrates how the slightest touch triggers a spring-release action in the seed pods of the weed commonly known as Touch-Me-Not (Impatiens capensis).
