| Abstract: | This study analyzed spatial location patterns Cercocarpus ledifolius Nutt. (cutleaf mountain mahogany) plants, classified as current-year seedling, established seedling, juvenile, and immature individuals, at a central Nevada study site. Most current-year seedlings were located in mahogany stands in which large, mature individuals had the greatest abundance. These stands had greater litter cover and a thicker layer of litter than areas with few current-year seedlings. Most established young Cercocarpus were located in adjacent Artemisia tridentata spp. vaseyana (mountain big sagebrush) communities, or in frequent canopy gaps between relatively few large, mature Cercocarpus . We discuss potential roles of plant litter, root growth characteristics, nurse plants, and herbivory in the establishment and renewal of Cercocarpus communities. |
