Abstract
Mediterranean dehesas are an archetypal example of High Nature Value Farmland in Europe. For three years we measured the contribution of scattered trees to the biomass and diversity of the herb layer and the relationship between the herb layer (biomass and diversity interaction) and the trees. We used 135 subplots distributed in four different directions and three distances from 15 trees selected randomly in a plot within a dehesa in central Spain. The specific questions we addressed were: i) to what extent do trees affect herb biomass? ii) What is the relationship between herb layer biomass and species diversity under tree influence? iii) What are the effects of trees and small changes in topography on the herbaceous diversity? Results differed due to the differences in annual water availability. We found the highest legume and forb dry matter at the edge of the tree crown and beyond the canopy. Species richness was positively related to legume dry matter, and both were higher at the bottom of the hillside, especially in dry conditions. Given the importance of tree influence on the biomass and diversity of grasslands, maintaining proper agroforestry management practices for trees and grasslands is an important task for conserving dehesa diversity and productivity under the conditions of high climatic and soil variability in Mediterranean dehesas.
