Yesterday, Intro to Field Ecology headed up to Thompson Pass for some hands-on fieldwork. On a beautiful fall day, I followed Morgan, Rachel, and Dahiana as they worked through a vegetation transect, collecting the kind of information ecologists use to understand what is actually happening on the landscape.
They selected a site and set out a 6-meter transect tape, marking points at each meter. At each point, they established a 1-meter perpendicular plot and recorded what they found: vegetation, soil, disturbance, aspect, elevation, and GPS location. They also identified the species and estimated the percentage of grasses, shrubs, mosses, lichens, and other vegetation within each quadrant.
It might look like three students measuring plants on a hillside, but a lot more is going on. They are learning how to collect consistent, usable data that can become part of a larger vegetation dataset and help us understand how landscapes change over time.
And Thompson Pass is a pretty incredible classroom. At about 2,678 feet, it sits above the treeline in the Chugach Mountains, surrounded by open alpine terrain. It is also known for its extreme snowfall, receiving more than 500 inches in an average year.
A great place to spend a fall day learning to read the landscape.
