They are keystone structures that may play important roles in maintaining ecosystem functions, services, and farmland biodiversity. However, scattered trees in agricultural landscapes are declining worldwide due to intensive land use. They are often perceived by farmers as having negative impacts on agricultural production. Large-scale assessments in different biomes of agricultural yield in scattered tree ecosystems remain rare. Filling this knowledge gap may help improve decision-making regarding the value of scattered trees in agricultural landscapes. Using meta-analysis, we found that, across four tree functional groups (deciduous, Eucalyptus, N2-fixing, evergreen oak), mature scattered trees do not compromise pasture yield. The sign and magnitude of scattered tree effects on pasture yield did vary, however, among tree functional groups and according to precipitation levels. Our study suggests that, as drought pressure increases abiotic stress, tree facilitation by N2-fixing trees, and competition by Eucalyptus, will become the more common interactions between scattered trees and pasture. Management options exist to conserve and restore scattered trees in agricultural landscapes, but new policies are required to support their widespread adoption by farmers.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>47</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Benavides, R.</style></author><author><style face="normal" font="default" size="100%">ROIG, S.</style></author><author><style face="normal" font="default" size="100%">Ponce, R.

However, this is a complex task due to the large number of influencing factors and the characteristic diversity and heterogeneity of this production. The objective of this work is to analyze and model the pasture production in a dehesa of Central Spain. The study site is located in the Dehesón del Encinar (Toledo) state, in a low density dehesa (17 trees/ha). A first geostatistical approximation is used with data from two contrasted sampling years: 2008 and 2009. Sampling data include zones under tree influence and pasture without any canopy cover. Geostatistical techniques and GIS result to be efficient tools for analyzing and predicting pas- ture production as well as for agroforestry systems management.
