Abstract (limIt: 200 words) Several sagebrush communities represent optimum Tevels of negative development plant productivity for certain peculiar sites, and therefore should be managed for their preservation. Other sagebrush communities may be profitably modified to favor forage species that are more palatable to domestic livestock. Modification techniques can range form subtle (i.e., grazing strategies) to tracematic (i.e., brush removal and revegetation), and an associated spectrum of management tactics are. described. Interrelationships between and problems associated with managment of forage resources, management of weeds, and management of insects (including grasshoppers, black grass bugs, and beneficial insects) are discussed. Economical analyses, the role of modeling as a management tool; and impacts of management tactics on wildlife and non-target species also are discussed. 17.

Onsager Editor , II CONTENTS PREFACE Sagebrush types as ecological indicators to This publication provides the text of 12 papers integrated pest management (IPM) in the that were presented by invitation at a symposium sagebrush ecosystem of Western North America entitled "Integrated Pest Management on Rangeland: K. L. Johnson State-of-the-Art in the Sagebrush Ecosystem." The objectives were to stimulate dialogue between Weed and brush control tactics in the sage­ research and extension personnel in range-related brush ecosystem 11 disciplines, to identify opportunities for D. L. Lancaster, J. A. Young, and R. A. Evans interdisciplinary approaches to management of pests or pest complexes on rangeland, and to provide a basis for prioritization of interdisciplinary Technology for seeding on sagebrush rangelands 15 research breeds for IPM on rangeland. J. A. Young and R. A. Evans Revegetation in the sagebrush ecosystem 19 The symposium was sponsored by Western Regional K. H. Asay Research Project No. W-16l, Integrated Pest Management. Shrubs and forbs for revegetation plantings in the sagebrush ecosystem 28 Topics for discussion and candidate speakers were E. D. McArthur, S. B. Monsen, and B. L. Welch selected by the following representatives of the Range Subcommittee of W-16l: K. H. Asay, Logan, Grazing management systems and tactics in the UT; R. A. Evans, Reno, NV; K. L. Johnson, Logan, sagebrush ecosystems 40 UT; J. B. Knight, Reno, NV; J. A. Onsager, Bozeman, W. A. Laycock MT, Chairman; G. L. Piper, Pullman, WA; and B. F. Roche, Jr., Pullman, WA.

DeWeese III SAGEBRUSH TYPES AS ECOLOGICAL INDICATORS TO SAGEWORT, WORMWOOD, AND SAGEBRUSH INTEGRATED PEST MANAGEMENT (IPM) IN THE SAGEBRUSH ECOSYSTEM OF WESTERN NORTH AMERICA The large and well-established genus Artemisia L. contains over 200 species distributed throughout the temperate regions of the northern hemisphere. Kendall L. Johnson The species include herbaceous, suffrutescent, and woody growth forms of wide ecological amplitude, but occur primarily in the arid steppe areas of Eurasia, North America, and Africa. In the Pacific ABSTRACT and Rocky Mountain West of North America, there are at least 30-35 well-defined taxa, although some Integrated Pest Management (IPM) is a structured authorities have recognized many more (McArthur approach to ecosystem management
