Growth and development dynamic of young holm oak high forest (Quercus ilex L.)-results of multiannual monitoring of natural regeneration by shelterwood cuttings

Holm oak (Quercus ilex L.) presents basic climax tree species in the warmer part of Croatian Mediterranean region. Early human settlement and its exploitation habits turned most of the ancient quality holm oak high forests to coppice standards and degradation forms. Respecting the principle of sustainable management as the basic postulate of Croatia forestry, the management aim for the most coppices should be conversion to higher silvicultural forms. Our scientific research brings successful and concrete results of monitoring of natural regeneration under the principles of shelterwood cuttings on the permanent trial plot. Basic stand structural elements have been monitored throughout multiannual measurements: DBH, tree heights, horizontal crown projection etc. The results showed a need for continuous and efficient tending measures with the protection of the regeneration area from game
