The Distribution of Halogeton in North America

Abstract

Halogeton [Halogeton glomeratus (Stephen ex Bieb.) C.A. Mey.], a livestock-poisoning plant from central Asia, occurred in most Great Basin states in 1954. Current distribution of the species was studied by surveying botanists, weed scientists and other specialists in 1980. The survey indicated that halogeton had spread into additional counties in all states occupied in 1954 and into southern California, New Mexico, and east of the Rocky Mountains to Nebraska. The largest infestations continue to be in the Great Basin and Wyoming.
