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.
