Professor Jean Burns and doctoral student Anna Osvaldsson lead a tour to see Anna's climate change experiment on the influence of changing winter snow cover on spring ephemeral plants. As climates in the Ohio region warm, models predict less winter snow cover and thus less insulation covering soils through the winter. The result may be greater soil freezing and greater mortality in our native plants. Anna's experiment manipulates over winter snow cover for many of our spring ephemerals including wake robin, Trillium erectum, jack in the pulpit, Arisaema triphyllum, and blood root, Sanguinaria canadense. In addition to the experiment, we will also explore some of the farm's beautiful populations of spring ephemerals.
