The following rangeland photo journal charts the changes that have occurred in a shadscale (Atriplex confertifolia) stand in southern Idaho between 1951 and 2002.

Many people are quick to blame any changes in range vegetation on livestock grazing. However, the area shown in this photo journal has not been grazed by domestic livestock since 1945 when most of a band of sheep were lost on this shadscale stand due to halogeton (Halogeton glomeratus) poisoning.

Concerned about halogeton, the Burley District of the Bureau of Land Management signed a cooperative agreement with Dr. Lee A. Sharp, University of Idaho professor of range management, to study the ecology and control of halogeton.
