Abstract

The aim of this study was to determine plant distribution at a nivation hollow located in a Mediterranean high mountain area and to analyse the effects of snow cover, wind exposure, proximity to moisture and the characteristics of the substrate on the vegetation. The AA. analyse these factors and interpret concurrent effects due to recent climatic change. The nivation hollow, called Ventisquero de la Condesa is located in the Sierra de Guadarrama. The AA. established 579 small sample plots in the study area, and grouped them into 29 transects. Due to environmental changes caused by recent global warming, several plant species, especially adapted to survival in snow conditions, coexist in the hollow with saxicolous plants that have invaded the site from adjacent grass and shrublands
