United States Department of Agriculture Proceedings: Forest Service Rocky Mountain Research Station Shrubland Ecotones Proceedings RMRS-P-11 September1999 Abstract McArthur, E. Durant; Ostler, W. Kent; Wambolt, Carl L., comps. 1999. Proceedings: shrubland ecotones; 1998 August 12–14; Ephraim, UT. Proc. RMRS-P-11. Ogden, UT: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 299 p. The 51 papers in this proceedings include an introductory keynote paper on ecotones and hybrid zones and a final paper describing the mid-symposium field trip as well as collections of papers on ecotones and hybrid zones (15), population biology (6), community ecology (19), and community rehabilitation and restoration (9). All of the papers focus on wildland shrub ecosystems; 14 of the papers deal with one aspect or another of sagebrush (subgenus Tridentatae of Artemisia) ecosystems. The field trip consisted of descriptions of biology, ecology, and geology of a big sagebrush (Artemisia tridentata) hybrid zone between two subspecies (A. tridentata ssp. tridentata and A. t. ssp. vaseyana) in Salt Creek Canyon, Wasatch Mountains, Uinta National Forest, Utah, and the ecotonal or clinal vegetation gradient of the Great Basin Experimental Range, Manti-La Sal National Forest, Utah, together with its historical significance. The papers were presented at the 10th Wildland Shrub Symposium: Shrubland Ecotones, at Snow College, Ephraim, UT, August 12–14, 1998. Keywords: wildland shrubs, ecotone, hybrid zone, population biology, community ecology, restoration, rehabilitation. Acknowledgments The symposium, field trip, and subsequent publication of these proceedings were facilitated by many people and organizations. We thank all who helped. In particular we extend thanks to Dave Lanier and his staff of the Great Basin Experimental Education Center of Snow College for providing publicity, facilities, and all around support; President Gerald Day and Vice President Rick White of Snow College, Forest Supervisor Janette Kaiser and Ranger Tom Shore of the Manti-La Sal National Forest, and Forest Ecologist Dea Nelson and Ranger Tom Tidwell of the Uinta National Forest for hosting various aspects of the symposium and field trip; Scott Walker of the Utah Division of Wildlife Resources, Great Basin Research Center, Gary Jorgensen and Dick Tennent the Rocky Mountain Research Station Great Basin Experimental Range, and Kelly Memmott of the Rocky Mountain Research Station Shrub Sciences Laboratory for logistical support; and Sallie Wolsey of the Shrub Sciences Laboratory and volunteer Chris Kitchen for clerical and general support. Technical sessions were chaired ably by Kent Ostler, Barbara Wachocki, Eugene Schupp, and Carl Wambolt. Field trip leaders were Durant McArthur, Steve Monsen, and Richard Stevens. We thank the Rocky Mountain Research Station Publishing Services for preparing the final publication. E. Durant McArthur W. Kent Ostler Carl L.

Kent Ostler *Charter members The Shrub Research Consortium was formed in 1983 with five charter members (see list). Over time SRC has grown to its present size of 25 institutional members. The SRC had three principal objectives in its charter: (1) developing plant materials for shrubland rehabilitation; (2) developing methods of establishing, renewing, and managing shrublands in natural settings; and (3) assisting with publication and dissemination of research results. These objectives have been met by a series of symposia sponsored by the Consortium and partners. This publication is the 10th in the series; the previous nine are listed on the next page. Proceedings of all publications to date have been published by the U.S. Department of Agriculture, Forest Service Intermountain Research Station and Rocky Mountain Research Station. The executive committee has plans for two more symposia: (1) in Provo, UT, in the year 2000 with a shrubland ecosystem genetics and biodiversity theme in conjunction with the 25th anniversary celebration of the establishment of the Rocky Mountain Research Station’s Shrub Sciences Laboratory; and (2) in Laramie, WY in 2002 with a shrubland ecosystem seeds and soil theme. Each symposium has had a theme but the executive committee has encouraged attendance and participation by shrubland ecosystem biologists and managers with wider interests than any particular symposium theme—the heart of the Consortium’s programs are wildland shrub ecosystem biology, research, and management.
