Abstract: The authors elaborated a new complex methodical approach to the evaluation of necrotic disease of beeches. They used two evaluation scales: a scale for the evaluation of stems and a scale for the evaluation of beech crowns. A four-degree scale for the evaluation of necrotisation of crowns completed the existing five-degree scale for the evaluation of necrotisation of stems. Combination of both these scales into one methodical approach produced the third, complex scale for the evaluation of necrotisation of whole trees. The proposed combined scale is recommended for the monitoring of beech necroses.
