Abstract
The presence of trees and adaptative management techniques play an important role within Mediterranean agroforestry ecosystems. Dehesas are good examples of Mediterranean 'High Natural Value' agriculture and produce important natural resources. Our work focuses on the influence of trees and main management techniques (stocking rate and site quality) on yield and alpha diversity of a Dehesa in Central Spain. We analysed total yield, Richness and Shannon-Wiener indexes within the herbaceous pastures under 16 holm oaks (Quercus ilex ssp ballota (Desf.) Samp) located in different management zones, in a very extreme dry year, with phosphoric fertilization, intensive stocking rate, medium stocking rate, and high soil quality or low soil quality. Tree canopy had a significant influence on herbaceous yield and alpha indexes (both were higher outside canopy influence). Phosphoric fertilization also had a significant effect on herbaceous yield and alpha diversity. Tree presence, livestock and soil management were shown to be important factors modifying the characteristics of herbaceous pastures in Mediterranean agroforestry systems, even in extreme climatic conditions
