Inventory of the degree of tree defoliation in small areas

The applied method of inventory enables the assessment of the degree of defoliation and spatial differentiation of tree health in small areas, which in turn, allows the detailed planning of protection and silvicultural measures. The proper assessment of the extent of tree defoliation and its spatial distribution is of fundamental importance for employing the ecological methods of management and rational protection of forest ecosystems, and should be included in the monitoring of both economically used and protected forests.
