Sample plots were evaluated by means of Mycorrhizas and fine roots. As evaluation criteria, the penetration by roots (density), the frequency of mycorrhizas, the state of health of the fine roots and the mycorrhizas, the number of different types of mycorrhizas, and abnormal forms of growth were described. Judging from these criteria, the investigated forest sites are in a good and stable condition. A correlation between parameters and altitude, between the density of fine roots and the use of pasture, and between the development of beech leaves and that of mycorrhizas was proved. First results regarding the storage and accumulation capacities of heavy metals in mycorrhizae are available. Furthermore, it turned out that the development of beech leaves may be used as an indicator of the processes going on in the root system.
