About this site

Cedar Creek is home to some of the state's largest intact stretches of oak savanna. This ecosystem, a transitional habitat between oak woodlands and grassy prairies, requires fire and grazing. At Cedar Creek, we use a combination of prescribed burning at various frequencies and grazing by a seasonal herd of bison (in one section of the oak savanna) to maintain and restore this unique habitat. Your photos help us track green-up in the spring, phenology throughout the summer and fall, and ecosystem health year-round.

More information about Cedar Creek's upcoming events and programs is available at https://cbs.umn.edu/cedarcreek/public-programs/upcoming-events . Information specifically about the Fish Lake Nature Trail is at http://z.umn.edu/fishlake 

About Cedar Creek Ecosystem Science Reserve

Cedar Creek Ecosystem Science Reserve is a University of Minnesota biological field station with many ecosystems and species found throughout the forests and grasslands of North America. Faculty, staff and students who work at Cedar Creek are dedicated to understanding how human activities, such as agriculture and fossil fuel combustion, are changing ecosystems. 



Many of the experiments at Cedar Creek consider the long-term consequences of human-driven environmental changes. These include ecosystem responses to things like biodiversity loss, nitrogen deposition, elevated carbon dioxide, habitat fragmentation, and changing community compositions. By taking pictures at our Chronolog stations, you can help scientists put together a long-term visual record of a few special places on our landscape!
