The Spanish Association of Arboriculture (AEA) was founded in December 1994 in order to establish itself as the official protective institution and promoter of activities related to ornamental tree in national territory.
AEA encourages since its inception training and scientific and cultural dissemination in arboreal matter and its areas of activity. Therefore, one of the main objectives set by the Association is the transmission of knowledge of tree biology and arboriculture techniques for all age segments and formation: from the smallest to adults; from neophytes in the field to advanced specialists.
