2017 Field Seminar: Prairies of the Chicago Region


Dates: June 3; July 29; September 30

Locations: 22-County Chicago Region (exact locations tbd)

Times: 9:00 AM to 5:00 PM

Instructor: Gerould Wilhelm, PhD

Cost: $650 (includes all three days)


Agenda:  Conservation Research Institute (CRI) is offering a three-day field seminar on the “Prairies of the Chicago Region.” As per Flora of the Chicago Region: A Floristic and Ecological Synthesis (Wilhelm & Rericha 2017), there are several types of prairies that comprise the region’s native prairie landscapes. These habitats can be wet to dry, and vary depending upon their underlying soils and geology, generally as Outwash, Moraine, Lake Plain, or Dolomite Prairies. The three-day seminar will be an intensive field study of remnant prairie habitats, with an emphasis on floral composition, phytogeography, and surface geology. The seminar is not an introductory course but one that is advanced with Latin plant names serving as the primary communication tool. Specific seminar locations and directions will be shared with attendees prior to the first field day. Two locations will be visited on each of the three days, with a lunch break in between each visit.
