Forests across the United States — and especially forest soils — store massive amounts of carbon, offsetting about 10% of the country’s annual greenhouse gas emissions and helping to mitigate climate change. But experts warn the strength of this carbon “sink” is declining and will level off around mid-century. One way to compensate for the declining sink strength of U.S. forests is to add more trees — by actively replanting after disturbances like wildfires or by allowing forests to retake marginal croplands.

The BioStation traces its roots to 1874, when the University decided engineering students needed a place to learn surveying. A temporary camp moved from site to site before settling down in 1908 in Pellston, Michigan. Eventually, doors opened to students of biology and botany. Today, researchers representing institutions from around the world conduct field-based research at UMBS. (Image courtesy of U-M’s Bentley Historical Library.)

Researchers have been logging and burning small, contiguous plots at the BioStation in a long-running experiment that seeks to approximate, on a tiny scale, the epic lumbering and wildfire disturbances that transformed the forest at the northern tip of Michigan’s Lower Peninsula and throughout the Upper Great Lakes region. The first plot was established in an aspen forest by plant ecologist Frank Gates in 1936.  (Image credit: Eric Bronson, Michigan Photography.)

Early U-M Great Lakes research was mainly concerned with fish and fisheries, but the emphasis began to shift to basic limnology, the scientific study of bodies of freshwater such as lakes, after the 1920s. (Image credit: Austin Thomason, Michigan Photography.)

Students from multiple schools and colleges constructed the BioStation’s straw bale building as part of a green building course created by Joe Trumpey, a professor at the School for Environment and Sustainability and the Penny W. Stamps School of Art & Design. Students have also constructed a straw bale building at the Campus Farm on the grounds of the Matthaei Botanical Gardens in Ann Arbor.

Here, researchers execute a controlled burn of wooded land at the BioStation in 2017. The burn plots provide snapshots of different-aged forests and contain a changing mix of plant and tree species. Except for these small plots and a few pockets of old-growth trees, most of the forest at the BioStation dates to 1911, the last time the property was severely burned by post-logging wildfires.

In 2016, researchers at the BioStation installed motion-triggered “camera traps” to capture snapshots of the state’s diverse wildlife. They were mainly interested in carnivores, the meat eaters. Can anyone identify this print along the sandy shores of Douglas Lake? (Image credit: Eric Bronson, Michigan Photography.)

It is commonly assumed that as forest ecosystems age, they accumulate and “sequester” more carbon. A recent study based at the BioStation untangled carbon cycling over two centuries and found a reality more nuanced than that. The research was published in the journal Ecological Applications.  (Image credit: Eric Bronson, Michigan Photography.)

The indoors is as visually stimulating as the outdoors at the U-M BioStation. The largest building at camp is the Alfred H. Stockard Lakeside Laboratory with 24,000 square feet of floor space designed for biological research. (Image credit: Eric Bronson, Michigan Photography.)

We’ll let this one speak for itself.
