So far as APIRS is aware, this is one of only two identification manuals
devoted exclusively to non-native invasive plants (the second one is described below). This book
treats 62 species, giving synonymy and botanical descriptions as well as sections on distribution
and life history, and includes referenced information about each plant's history of introduction
and its impact on native ecosystems. Most of the photos are larger-than-usual for similar ID
manuals, a welcome improvement. (Unfortunately, the unreliable binding of this book makes it
less useful, especially in the field, than it might be.)
