Grasses of the Southern Appalachians

2 Credit Hours
May 4–8, 2026
Instructor: Dr. Paul McKenzie, Retired Endangered Species Coordinator, U.S. Fish and Wildlife Service; Volunteer and Independent Contractor

This course provides a comprehensive introduction to the identification, morphology, and ecology of grasses native to the Southern Appalachian region. Through a combination of lectures, lab-based keying exercises, and immersive field excursions, students will develop the skills necessary to recognize and differentiate grasses from related plant groups such as sedges and rushes.

Classroom sessions will include detailed instruction on floral morphology, focusing on the structure and variation of grass flowers. Students will examine illustrative photographs and diagrams, review terminology essential to grass identification, and receive a full-color copy of the instructor’s presentation materials. Laboratory components will emphasize hands-on identification techniques using multiple dichotomous keys and a curated collection of over 200 pressed grass specimens housed at the Highlands Biological Station Herbarium.

Field trips to local habitats will provide practical experience observing grasses in diverse landscapes and ecological settings. During past field excursions to the Buck Creek Barrens in Clay County, participants have encountered multiple timber rattlesnakes—students should therefore come prepared with appropriate field attire and exercise caution in these environments. Depending on the timing of the course, heavy grass pollen may also be present; students with allergies are encouraged to bring suitable sinus medication.

Students enrolling for academic credit will complete an open-book final examination designed to reinforce key identification skills and botanical concepts.
