Microclimatic protection proves ineffective in improving the survival and development of holm oaks
A research group from the ‘Camino de Purchil’ Centre of the Andalusian Institute of Agricultural, Fisheries, Agrifood and Organic Production Research and Training (IFAPA) in Granada, the ‘Hinojosa del Duque’ IFAPA Centre in Córdoba, and the University of Granada have studied the effect of tree shelters on the regeneration of open oak woodlands (known in Spain as dehesas). The results of the study reveal that the survival rate of the trees is increased by both the direct seeding of acorns and the planting of nursery-grown seedlings.
