FLBS at a Glance

Legacy - We are the second oldest biological field station in the US and the oldest west of the Mississippi River. We have one of the oldest, contiguous lake datasets in the world. 

Research - We work on a watershed fed by Glacier National Park and other pristine wilderness areas, allowing our research to focus on both natural processes and human-induced effects.

Education - We offer premier field-based summer ecology courses, as well as graduate level studies in ecology and limnology. Our students come from across the United States and around the world. 

Outreach - We feel strongly that science should be disseminated to the greatest number of people, including the local citizenry and the worldwide community. We offer community presentations, expert seminars, and interactive field-based classrooms.


Stop by and visit us. We'd love to show you around!
