In rural areas the veteran age or great size trees are derived from the human action, such as, for example, specimens in ex wooded pastures, woods or grazed, even so, with low density. The presence in the same areas of cultivated form of Olive (Olea europaea subsp. Europaea L.), or types prior to domestication (Olea europaea subsp. Sylvestris (Brot.) and populations from crossing between the two forms that originate from dissemination from natural cultivars, justifies the complexity of the species. In this paper we report on the technical elements of a conservative approach to monumental Oleastro of Luras (Sardinia) and the surrounding areas. Frequenting the tourist and cultural site, which also includes archaeological relevances, led to the acquisition of the area by the local municipal administration, that has pursued the enhancement using the guidelines in the University of Sassari survey, prepared by a team of researchers and professionals specialized arborists in the management of veteran trees.
