Most meaningful for those recorded forest damage is the state of tree crowns, in particular the defoliation . Geological, pedological, botanical, meteorological, hydrological and forestry parameters can from the sample plots the average productivity of typical forest regions are estimated. A soil condition survey is usually part of the forest condition survey.
