Joseph M. DiTomaso Evelyn Healy The California Weed Science Society is proud to sponsor the first comprehensive identification manual for aquatic and riparian weeds west of the Rocky Mountains. Contains over 560 color photographs of 170 species! Includes submerged, floating leaf, and emergent aquatic weeds in rice production fields, water use systems, and wildland areas. The combination of color photos, text descriptions, keys, tables, and a glossary will increase the accuracy and speed of aquatic and riparian weed identification. In addition to the individual description of species or related species, the text also contains: shortcut identification tables to groups that share similar, unusual or relatively uncommon characteristics keys to floating-leaved and submerged aquatic weeds, pondweeds, and grasses or grass-like species comparison tables for difficult to identify groups illustrations and glossary of terms bibliography of pertinent literature A valuable reference and field manual for weed control specialists, land managers, rice growers, golf course superintendents, landscape professionals, and anybody interested in learning more about identification of important weeds of aquatic and riparian systems. Aquatic and riparian weeds are major problems in wildlands, rice production, and water use systems. This practical guide is a lavishly illustrated manual providing information on the identification and biology of several important weed species. Each species was researched to provide accurate information on the distribution, habitat, propagation and phenology, management considerations, and characteristics that allow distinguishing between similar or related species.
