Description: This is an intensive introductory/intermediate course on sedge identification and keying with an emphasis on species occurring in Northern California and the Pacific Northwest. The workshop starts with an introductory review of sedge taxonomy, ecology, biogeography, and essential sedge keying terminology and morphology. The rest of the day will be guided dissection and keying of specimens in the laboratory using a microscope and the JepsonManual 2ndEdition. Keying will be punctuated with guidance and commentary on keying groups and species characteristics. Many specimens will be available for review, dissection, and comparison. This workshop is geared for beginner and intermediate caricologists, but familiarity with keying plants in the Jepson Manual is required.

Venue: Humboldt State University, Arcata, CA. Directions and additional information will be provided to registered participants about a week before the workshop.

Schedule: 9:00am to 5:00pm with one hour for lunch. Registration, goodies, and settling-in begin at 8:30am.
