  • The effects of harvester ant (Pogonomyrmex rugosus) nests on soil characteristics and winter annual plants were measured at three locations characterized by different soils and dominant vegetation on a desert watershed. The purpose of this investigation was to answer the following questions: 1) How does the modification of soil properties and the ratios of resources (e.g., water-N) by ants alter species assemblages of winter annual plants at the edge of the ant nests? 2) How does the "spring cleaning", clipping, predation or herbivory by ants affect success of the winter annual plants at the edge of ant nests?, and 3) Are there significant differences in the floristic assemblage and belowground standing crop (root biomass) between the edge of ant nest and the surrounding unaffected soils? This dataset contains results for the density and cover of winter annual plants at the perimeter of ant nests and at reference sites. Please see JRN packages 210368002, 210368002, and 210368004 for chemistry, organic matter, and water content data. This study was conducted in 1987 and is complete.
