Beginning and experienced birders alike enjoy this quiet walk with an expert guide to learn about our avian neighbors active in the Arboretum Forest year round as well as species passing through on migratory routes. Scheduled during a monthly quiet time in our gardens and on our grounds, participants can turn their full focus to the treetops and tune their ears to beautiful birdsong. Seasoned naturalists and ornithologists frequently reference their “spark bird,” the bird that sparked an avid interest to learn more and that now leads to their commitment to protect species increasingly imperiled by climate change and other threats to their habits and habitats. Let our guide arrange an introduction to your spark bird and open your eyes to the wonder of birding. Binoculars are available for loan, and the guide will touch on the range of equipment and apps available. Look for the guide’s follow-up list of birds seen and heard on your walk. All proceeds from our classes go to support conservation education at The North Carolina Arboretum.

A Wing and a Prayer is the story of a band of scientists, birders, hunters and ranchers working to save birds set against the loss of a third of North America’s bird populations in the past 50 years. Avid birders by avocation and veteran journalists by vocation, Anders and Beverly Gyllenhaal traveled over 25,000 miles in a refashioned Airstream, finding inspiring and encouraging rescue missions all across the hemisphere, but they also discovered how much more can and must be done to halt the dramatic declines. In this impassioned talk, they walk us through the steps any one of us can take to contribute to saving our imperiled bird populations.

Notable faculty included Josef Albers, Anni Albers, Buckminster Fuller, Jacob Lawrence, Willem de Kooning, John Cage, and Merce Cunningham. Students who attended Black Mountain College include Ruth Asawa, Robert Rauschenberg, Ray Johnson, Hazel Larsen Archer, Kenneth Noland, and Jonathan Williams. We will watch and discuss the documentary Fully Awake. This will be accompanied by a Walking Tour of the Lake Eden Campus and the opportunity to view the current exhibition “Weaving at Black Mountain College: Anni Albers, Trude Guermonprez, and Their Students” on view this fall at the Black Mountain College Museum + Arts Center.

It is easy to fall for the poetry and charm of common plant names. Who can resist the romance of plants with names like “Loves-lie bleeding,” “forget-me-not” or “morning-noon-and-night”? However, when understood and used appropriately, botanical Latin can help in understanding the origin of a plant or important characteristics such as its form, color, shape or size. Based on the book Latin for Gardeners, this class will explore the reasons to use Latin for plant names and how to use botanical Latin to improve gardening efforts. Who says Latin is a dead language? Instructor Phil Roudebush enlivens this core class and gives students an essential tool for better understanding botanical nomenclature and taxonomy.

The Arboretum hosts a unique learning opportunity with a dynamic team of scientists from the National Centers for Environmental Information (NCEI) and the North Carolina Institute for Climate Studies (NCICS) leading a four-part series on Climate Change Science starting in early October. Learn from the scientists who collect and maintain weather observations, records and data sets used by partners, scientists and decision makers across public and private sectors the world over. Science-backed presentations along with discussion will place our local weather and climate within a global perspective, examining what drives Earth’s warming temperatures and the increasing extreme weather events such as hurricanes, floods and fires, while considering what the data show on trends and the effects on seasons and biodiversity. The course covers four main areas: 1) basic climate and climate change, including what drives the seasons, climate, and what is known about climate past and present; 2) climate change and variability, including how scientists know the climate is changing through tracking global and national climate trends; 3) climate and weather, including how climate is, and is not shaping extreme events as well as Western North Carolina weather and projections; and 4) adaptation, including strategies used to prepare for a changing climate.

Many of us intuitively recognize common plants like oak trees, ferns, and grasses. But could you distinguish a white oak from a chestnut oak? Or tell a grass from a sedge from a rush? Reading the landscape and identifying plants, like art, begins with observation! In this day-long workshop students will hone their field sketching skills and plant knowledge through the creation of observational artworks of native plants and landscapes. Students will spend the morning in the Arboretum’s Native Azalea Collection. This unique and dynamic landscape features winding pathways through diverse natural plant communities including rhododendron thickets, wetlands, and hardwood forest. With a combination of instruction, demonstration, and observational drawing, students will study the structure of these native plant communities. In the afternoon, students will walk to one of the Arboretum’s outdoor classrooms where they will have the opportunity to study plant samples up close and attune themselves to the small and subtle features used in plant classification. While all levels are welcome, this class is intended more for students with some prior drawing experience; however no prior experience in plant studies is necessary to participate — just curiosity!

Arboretum Azalea Collection Curator Carson Ellis will lead a walking tour of the landscape to introduce students to the plant communities and species growing in the Native Azalea Collection’s landscape. We will cover basic tools and skills for plant identification, including the use of dichotomous keys. Scientific illustrator Erin Ellis will lead students in observational drawing, demonstrating field sketching techniques for pencil and watercolor. Students will have time to create two completed field studies with an objective to represent the identifying features of native plants in Western North Carolina’s landscape.
