A simple key on the inside front cover directs users to any of 11 categories, such as ‘cloven hooves’, ‘paws’ or 'tramline-like trails'. Nearly 100 animals or closely related groups of animals are depicted; for each, there’s: a silhouette of front and back feet and a colour photograph of the track; the average measurements for each track; a short description of the track and information about the circumstances and likely habitat. Concise and to-the-point, this pocket-sized reference will prove indispensible in the field, no matter the experience of the user.
