These include poisonous, hallucinogenic, medicinal, and edible plant life as well as native and non-native plants that have the potential to become troublesome weed species. Complete and accurate details are offered on plant collection and preservation. A special chapter provides nontechnical investigations and projects for those pursuing areas beyond the realm of gathering and identifying flora. Conservation and habitat preservation are emphasized throughout the book. Handsomely illustrated, informative, and easy to read, this hands-on guide will prove an accessible and invaluable companion to professional and amateur naturalists as well as to students and the general public.
