Generalitat Valenciana Consejo Superior de Investigaciones Científicas (España) Spatial association Facilitation Plant mortality Semi-arid Drought Stipa tenacissima SE Spain 10 páginas, 3 figuras, 3 tablas. The establishment and development of the plants of S. tenacissima L. organize a source-sink pattern of water and sediments from bare soil areas to tussocks on mountain slopes forming small terraces or terracettes upslope of tussocks. We hypothesized that terracettes enhance woody plant survival compared with woody plants on bare soil. We examined this hypothesis at three locations in south-eastern Spain after a severe drought from 1993 to 1995. The spatial association of individual plants and the pattern of plant mortality support the hypothesis that the terracettes formed by S. tenacissima tussocks facilitate woody plants. The prediction that facilitation dominates interference during stress periods such as drought was supported by mortality patterns. Drought effects alone do not explain spatial patterns of woody plants in the two-phase mosaic steppe of Stipa tenacissima. This research was supported by the Plan Valenciano de Ciencia y Tecnologí de la Consellería d’Educació i Ciència de la Generalitat Valenciana (Spain) (GV94-2311). Maria Gasque benefitted from a doctoral fellowship of the Consejo Superior de Investigaciones Científicas (CSIC). The authors would like to thank Dr A. Cerdà, D. Montesinos, Professor W. G. Whitford and two anonymous reviewers for their constructive comments on the manuscript.
