In 1991, a group of
scientists associated with the Western Society of Weed
Science in cooperation with the Western United States
Land Grant Universities Cooperative Extension Services
published a plant identification book. Members of
the WSWS determined that an identification book showing
and describing important weed species in the western
United States was needed.
Weeds discussed in the book
were selected by weed scientists who are members of the
WSWS. Weeds were selected because of their
abundance, ability to reproduce, compete, and spread
rapidly, as well as those that are toxic to livestock or
humans. An attempt was made to include a
representative cross-section of the common agronomic,
rangeland, horticultural, and non-cropland weeds of the
western United States. If plants are not included
in the publication, please contact your county extension
agent or university herbarium for proper identification.
