Abstract
AbstractThe aim of this study was to investigate the structural changes in a community of heathland when subjected to experimental cutting and nitrogen fertilization. Random patches with significant proportions of Calluna vulgaris and Erica tetralix were selected in three areas (mountain passes) in the Cantabrian mountains, Spain. In April 1998 experimental treatments (cutting and fertilizing with 5.6 g/m2 ammonium nitrate) were imposed in each of the three areas. Fertilization does not have a significant influence on species number. Cutting increased the diversity of woody and perennial forb species. Cutting plus fertilization significantly increased the number of woody, perennial forbs and perennial graminoid species.
