Abstract
This diploma thesis evaluates about the current state of health of forests in the National Park Czech Switzerland. The aim was explored the most pathogenic fungi found in the national
park and was determined their distribution, meaning a major threat for trees of the area.
The first part describes about the fungal pathogen found in the national park. And presents their description, biology, symptoms of damage and, ultimately, their seriousness and protection. Second part describes the most important trees of the field. In the National Park are the most important spruce, Scots pine, silver fir and hardwoods are mainly beech. The third part describes a self-monitoring and survey identified fungal pathogens based on field research. Important pathogens are from genus Armillaria, types Lophodermium pinastri , Lophodermium seditiosum, Lophodermium piceae, Meloderma desmazieria and Hymenoscyphus fraxineus.
The final section assesses the condition of health of trees. For that assessment was used defoliation. The assessment was performed in stands of spruce, ash and fir. There were assessed 348 specimens with average defoliation of spruce 43.5%, 194 specimens with average ash defoliation 51.2% and for fir´s 71 specimens was average 52.7% defoliation.
Work submitted actual, comprehensive overview about the state of health of forests in the National Park Czech Switzerland in terms of possible danger from fungal pathogens. No fungal species are found currently significantly jeopardizes the health status of assessed trees.
