The percentage of radiation transmitted through the tree layer to the understorey pasture in dehesas of west-central Spain has been modelled. To achieve that, different allometric relationships between tree ages and stem diameter (DBH), and between stem diameter and canopy size (tree height, canopy ...

The distribution of resources (light, microclimate, soil moisture and soil nutrients) and fine roots (herbaceous plants and trees) around trees were studied in four dehesas with three types of management: cropped (forage), grazed (native grasses) and encroached (matorral). Additionally, the forage...

The aim of this study was to understand the effect of holm-oak (Quercus ilex) on the soil nutrient concentration and its consequence for the yield of understorey forage (Avena sativa) in four dehesas of CW Spain. The soils of the dehesas varied in soil fertility (chromic Luvisols and Achrisols, and ...
