ABSTRACT: Short Canyon lies at the eastern end of the southern Sierra Nevada within the Bureau of Land Management's Owens Peak Wilderness Area in Kern County, California. The canyon has an unusual floristic composition, and is botanically diverse, comprising elements of the southern Sierra Nevada, Great Basin, and Mojave Desert. Elevation ranges from 2400 ft at the canyon mouth to 5700 ft at the head of the canyon. There are 56 families, 182 genera, and 324 species currently documented within Short Canyon. Approximately 500 vascular plant collections were made within the study area. The primary objectives of this study were to catalogue, voucher, and create an annotated checklist of Short Canyon's vascular flora.
