Its conservation value is dictated by the archaeological investigations of the important intangible value of its cultural heritage. The management plan drawn by the park administration is oriented towards these archaeological investigations. Zoning of the park has been done accordingly under the classification of intangible zone, primitive zone, extensive use zone, service and CONAF (1976) zone and special use zone. A harmonious blend of conservation activities in the reserve areas (including monoliths and structures) with agricultural activities, livestock grazing, orchards and traditional fishing sites has evolved in the integrated management plans for the island.
