Critical Connections Ecological Services, Inc. is offering a two day sedge identification workshop on Thursday, June 8 and Friday, June 9, 2017. In its seventh year, this intensive identification course will be taught by Jason Husveth and will focus on the Sedges (Carex) of Minnesota. This two day workshop will be taught 75% in the lab and 25% in the field, and will include the a brief introduction to all of Minnesota’s 15 Cyperaceae genera, as well as identification of dozens of Carex species from live plant material.  Over 50 Carex species were presented as live material at last year’s workshop, as well as more than 20 additional species representative of other Minnesota sedge genera.  The class will be useful to novice and experienced field botanists, wetland ecologists, and wetland professionals.  New in recent years, the instructor will project live macro/micro images and video feed while teaching the group to key from live specimens.  Students are encouraged to keep their pressed specimens of positively identified Carex species for their future reference and learning.

Students can expect to complete the course with:

1) A basic knowledge of all of the sedge (Cyperaceae) genera occurring in Minnesota (15 genera as per Flora of North America 2002, vol. 23),

2) The ability to recognize and identify common and unusual Minnesota native Carex species in the field,

3) Knowledge of required collection material to enable proper Carex identification in the lab, and,

4) The ability to use dichotomous keys to identify Carex to species in the field. Students will be taught useful Carex field-identification concepts and shortcuts, as described in Voss’s Michigan Flora (vol. 1.), G.A. Wheeler’s 1981 dissertation: A Study of the Genus Carex in Minnesota, the Flora of North America (vol. 23; Cyperaceae), and Husveth’s revised Key to the Carex of East-Central Minnesota. 

Jason Husveth is a professional ecologist and botanist working throughout Minnesota and the Upper Midwestern United States. Jason has over twenty years of academic, field, and herbarium experience identifying, collecting, photographing, and documenting sedge species in Minnesota and the Upper Midwest and throughout the Eastern United States. Jason has been trained in sedge identification by Dr. Anton Reznicek (Flora of North America: Cyperaceae and Michigan Flora), Dr. Robert H. Mohlenbrock (Illustrated Flora of Illinois),  Dr. Susan Galatowitsch (University of Minnesota), and Dr. William Norris (Sedges of Iowa). Jason has taught sedge identification courses in the field and in lab settings, and has lead dozens of plant identification field trips to native wetland and upland habitats throughout Minnesota. Jason not only knows and loves sedges; he knows how to teach others to navigate through sedge diversity to understand the underlying concepts on how to identify, learn, and remember sedge species of Minnesota.
