When you're out and about, keep this tabbed booklet by Jonathan Poppele close at hand. Featuring only California mammals, the booklet is organized by group for quick and easy identification. Narrow your choices by group, and view just a few animal tracks at a time. Realistic track illustrations of 110 species, along with size information, sample gait patterns, and a step-by-step guide to track identification, help to ensure positive ID. The pocket-sized format is much easier to use than laminated foldouts, and the tear-resistant pages help to make the book durable in the field.
