This practical, beginner course will explain how Botanical (Dichotomous) Keys work, how to find your way around them, and will guide you through their use and application – and their limitations.

“Keying out” is a daunting but essential skill for anyone interested in botany. Learning to name the species you find is an important step in understanding the environment around you.

The course will start in a clear and simple way, with an explanation of the principles behind a key, then some practical work using the Field Studies Council fold-out Tree Name Trail. It will be a gentle introduction to the world of botanical keys. Once everyone is feeling confident, we will move on to more in-depth botanical keys, working mainly from The Vegetative Key to the British Flora, and The Wildflower Key. You will learn the ID essentials and then work your way steadily through some different samples, appreciating the benefits and limitations of the key as you go.
