Undergraduate students have contributed significantly to the lab's research. Northland College students are welcome to inquire about possible opportunities to work with Dr. Johnson on a group project or an independent capstone project.



Bridget ('22) is a dual Biology and Natural Resources: Fisheries and Wildlife Management Major. Her senior capstone research focuses on analyses of change and assessment of precision in population monitoring of rare Arctic/Alpine plant species in Isle Royale National Park. Her work is in collaboration with Dr. Sarah Johnson and the National Park Service. She's a TA for the Vegetative Communities of Northern WI class (BIO328). In summer 2021, she worked as a water resource technician with the Mary Griggs Burke Center for Freshwater Innovation. She aims to further pursue plant ecology in graduate school.


'22 B.S. degrees in Geology and Biology; Patrick is currently the student greenhouse manager. He brings a wealth of knowledge about nursery plant care and an artful eye for organizing our conservatory collection.



Claire (’23) is a Natural Resources: Ecological Restoration Major. Claire has been involved in helping conduct an ongoing phenological study of native plants in the northern region of Illinois. She has spent the past year volunteering with Mchenry County Conservation District and is now a research assistant in Dr. Sarah Johnson’s lab. Claire plans on pursuing Ecology and Mycology in graduate school.


Josey ('22) is a dual Water Science and Natural Resources major working in the herbarium this year.



Abigail ('23), is pursuing B.S. degrees in Natural Resources: Ecological Restoration and Biology. This is her first year as a Research Assistant! She is pumped to be learning more about the flora of Wisconsin. Over the summer she worked as a tow boat driver and outfitter in the Boundary Waters Canoe Area Wilderness.


Molly ('22) works in the Center for Science & Environment greenhouse.



They work for lots of treats, pets, and walks. They help collect seeds in their fur and they sniff out blueberries. Both pups were rescued from northern Wisconsin animal shelters.
