When we reached the Biocore Prairie, Seth told how Ann Burgess and Curt Caslavka got permission for UW biology honors program students to learn ecology by restoration of this badly degraded land, beginning with 3/4 acre in 1998. By 2016, the land under restoration had increased to 12 acres, making it the largest laboratory on campus. Seth compares this highly manipulated living laboratory to an Erlenmeyer flask. As one example, he showed us a map of the prairie with the dates of burning identified for individual 20m2 areas. While it is recognized that fire is essential to prairie restoration, this burn study can help to determine the optimum frequency of burning.
