Contributions range from broad perspectives on restoration of arid lands to specific studies of arid land plant ecology and improvement. The proceedings emphasizes the use of revegetation to rehabilitate arid to semiarid lands for a variety of objectives. The symposium consisted of oral presentations including a plenary session, posters, and field trips. For convenience, we have divided these entries into six sections: Overview, Restoration and Revegetation, Ecology, Genetic Integrity, Management Options, and Field Trip. This volume includes 62 of the 82 papers and posters presented at the symposium (Shrub Research Consortium 1993) and one of the three field trips. The Nevada Test Site field trip is written up in these proceedings. The Viceroy Gold's Castle Mountain Gold Mine field trip featured a tour of a greenhouse used to propagate Mojave Desert plants from seed and tissue culture and a demonstration of salvaging topsoil and plants for Mojave Desert restoration. The Lower Colorado River and Mojave Desert Spring Restoration field trip featured problems with an alluvial desert river and riparian ecosystems and various attempts to restore health and function to them. The symposium also included workshops on Large-Scale Rangeland Revegetation and on Revegetation Contracting and Practice.This symposium proceedings reflects the growing interest in and the development of the science and practice of restoration ecology.
