Weed Control in Natural Areas in the Western United States is the first comprehensive book to focus on control options for invasive plants in natural areas. Fifteen authors, led by Dr. Joe DiTomaso of UC Davis, compiled information on control methods for 340 species in 13 western states, covering rangelands, grasslands, pastures, riparian and aquatic areas. Each species account includes chemical, mechanical, biological and cultural control options, based on literature and the personal experience of the authors.

The goal of the authors is to provide as many options as possible for an Integrated Pest Management approach. The book also includes information on the range of control techniques and equipment used in natural areas, as well as safety and environmental considerations, herbicide characteristics, rainfast periods and grazing and haying restrictions for terrestrial herbicides, a list of species with biological control agents either available or under development, and conversion tables.

This book will be an excellent resource for any land manager confronting invasive plants.
