[EN] 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.
