Grazed Mediterranean open woodlands, as the Iberian dehesa, are an outstanding example of silvopastoral system where shrub encroachment has been proposed as an effective means to facilitate tree seedling recruitment and ensure the system persistence. The aim of this essay is to test the effects of different intensity of shrub encroachment on different fodder components of the system: acorn production, forage shrub and grassland yield. Metabolic Energy (ME) was increased by R. sphaerocarpa due to the increase of grass production and the contribution of shrub fodder in addition to the supply of acorns. Instead, the ME supplied by C. ladanifer layer, did not compensate the reduction in grassland and acorn production because of the low metabolic energy that C. ladanifer canopy provides.
