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.

2 Credit Hours May 18–22, 2026 Instructor: Dr. Paul Manos, Duke University Cost: $500.00 This course welcomes students, professional biologists, and plant enthusiasts alike. Centered on the rich botanical diversity of the Highlands Plateau, it provides both an introduction and a refresher on studying vascular plant diversity. Through a community-based lens, participants will explore the flora of the Blue Ridge during field excursions and hands-on identification exercises. Course objectives include: Understanding key distinguishing features among lycophytes, ferns, and seed plants. Learning field characteristics of common and rare species and the habitats they occupy. Developing confidence in using identification keys. Gaining a clearer understanding of the ecology of major regional plant communities and the biogeography of their species. This immersive field experience offers a strong foundation for anyone interested in the botanical richness of the Southern Appalachians.

2 Credit Hours May 25–29, 2026 Instructors: Dr. Joey Shaw, UT-Chattanooga This course is designed for anyone wishing to strengthen their skills in observing, collecting, identifying, and assessing the ecological “quality” of wetland plant species. Accurate identification is essential not only for understanding wetland integrity and ecological condition, but also for conducting professional wetland delineations. Whether you are new to wetland flora or looking to sharpen existing skills, this course offers a supportive environment for learners at multiple levels. Students should have a basic understanding of botanical terminology and plant structures, but there is no expectation that everyone enters with the same experience. Participants may focus on different plant groups—woody species, graminoids, or others—collecting specimens that align with their individual interests. Each day features a field excursion to a local wetland within roughly an hour of the Station. Students will collect plant specimens of interest, then return to the lab for hands-on identification work using dichotomous keys, online herbarium resources, and other reference materials. Together, we will use tools such as coefficients of conservatism to better understand the ecological integrity of the wetlands we explore. While the range of wetland types will be limited to what is found regionally, the focus of the course is on building practical, adaptable identification skills. Throughout the week, Dr. Shaw will serve as a guide in interpreting key couplets, terminology, and diagnostic features. Students will also be encouraged to develop their own reference collections; the final portion of the course will be devoted to assembling and refining these materials. A working draft of the instructor’s forthcoming Second Edition of the Guide to the Vascular Plants of Tennessee will serve as the primary key for species identification, and copies will be provided.

4 Credit Hours May 25 – June 5, 2026 Instructors: Kenneth H. Kozak, Ph.D. (University of Minnesota) & Joseph H. K. Pechmann, Ph.D. (Western Carolina University) The Southern Appalachians are home to one of the richest and most ecologically significant salamander assemblages on Earth. This immersive field- and lab-based course introduces students to the extraordinary diversity, biology, and evolutionary history of these remarkable amphibians. Through a blend of lectures, guided discussions, hands-on laboratory work, and targeted field excursions across multiple Appalachian mountain ranges, students will explore foundational and advanced concepts in evolutionary biology and ecology. Topics include reconstructing evolutionary histories, species concepts and delimitation, life-history variation, population and community dynamics, and the role of salamanders in forest ecosystems. Readings from primary literature will deepen understanding of current research and methodologies. Students will gain experience identifying regional taxa, conducting field and laboratory analyses, and interpreting evolutionary and ecological data—while engaging directly with the landscapes that make the Southern Appalachians a global hotspot for salamander diversity. Prerequisites: Introductory biology, ecology, or evolution, or permission of the instructors.

2 Credit Hours June 1–5, 2026 Instructors: Dr. Joey Shaw, UT-Chattanooga True sedges are famously challenging to identify. With numerous species often growing side by side in the same microhabitats, reduced and specialized floral structures, unique terminology, and diagnostic features that may rely on very small measurements—or even mature material—students of botany can easily feel overwhelmed. It is no surprise that sedges are among the plant groups learners struggle with most. This course focuses on two primary goals: Building fluency in sedge terminology and learning how to confidently apply and interpret that terminology when using identification keys. Understanding the key characteristics that distinguish the many taxonomic sections of the genus Carex—the largest and most complex sedge genus—as well as how to separate Carex from other spring-flowering sedges. Using herbarium specimens, newly collected material, and additional plant samples provided in class, we will assemble an in-room reference collection organized by genus and Carex section. This hands-on approach allows students to compare specimens directly, reinforcing both visual recognition and taxonomic concepts. This workshop is designed to strengthen identification skills and build confidence in working with this large and intricate group of plants. For most participants, our focus will remain at the level of distinguishing Carex sections rather than resolving species-level identifications—though students wishing to work at the species level are welcome and encouraged to do so!

2 Credit Hours June 8–12, 2026 Instructors: Dr. Laura Boggess, Mars Hill University & Mr. Gary Kauffman, USFS (Emeritus) Cliffs and rock outcrops are among the most striking and ecologically distinctive landscapes in the Southern Appalachians. These environments support rare, endemic, and specialized species shaped by extreme conditions and long-term geological processes—yet they remain understudied, in part due to their inaccessibility. Highlands Biological Station lies within one of the most rugged and geologically diverse regions of the Appalachians, offering access to unique communities such as high-elevation granitic domes, rocky summits, cliffs, and montane red cedar woodlands. In this weeklong, field-intensive course, we will explore the emerging field of cliff ecology and conservation. Most of our time will be spent outdoors, developing field skills, observing species assemblages, and examining how organisms interact with one another and with their physical environment. Through complementary lectures, readings, and discussions, we will consider the natural history of these ecosystems, the ways humans engage with them, and how we can shift our relationship toward stewardship and reciprocity. By the end of the course, you will have built a strong foundation in cliff and outcrop ecology, connected with a community of like-minded peers, and deepened your relationship with the distinctive landscapes of the Southern Appalachians.
