In each study plot, we mapped every S. ciliata and A. caespitosa reproductive plant and seedling using a high-resolution Differential Global Navigation Satellite System (DGNSS) (Viva GS15, Leica, Switzerland) with an accuracy of 5 cm for x and y coordinates. We also measured plant diameter and the number of inflorescences of every reproductive plant. To account for potential seedling sources outside the study area, we also recorded the location, diameter and number of inflorescences of reproductive plants in a buffer zone of two meters around the plots.
