This course offers an introduction to the ecology and identification of mosses and liverworts found in peat-accumulating wetlands in Wisconsin. They will focus on species found along the Cedarburg Bog boardwalk, but the instructor will bring additional specimens from other sites in the region to examine as interest and time allow. Some prior knowledge of general botanical terms and life cycles will be useful, but not essential to getting a lot out of the course. The course will comprise short lectures, slow walks (for observation, field ID, and sample collection) along the boardwalk and trails, and time at the microscope using technical dichotomous keys and practicing terminology.
