In this paper the influence of care, cleaning and thinning on the health condition of chestnut, on the chestnut blight disease and various types of cancer formations are investigated. The aim of this work is the protection of chestnut trees and raising the quality of chestnut stands and trees and to determine how to manage with the chestnut stands to its preservation. For this purpose, the experimental plots were established in the Forest administration Sisak, in Forest office Hrvatska Kostajnica in Management Unit Šamarica I, department 91A. Experimental plot I was managed with strong thinning intensity: one to two chestnut trees were left on the stump. Experimental plot II was maneged with lowthinning intensity: three to five chestnut trees were left on the stump. Removed trees were irregular growth, infected with active cancer. The healthy tree and tree with healing superficial necroses were left. The size of experimental plots was 50 x 100 m. On experimental plots the health condition of trees, differengt types of cancer formations and diameter degree of trees were registered. The survey was carried out in 2010th year in the fall at the end of vegetation. In the Forest office Hrvatska Kostajnica in management unit Šmarica I in the compartment 92 a the samples of bark infected with cancer were collected and the fungus Cryphonectria parasiticawas isolated. Population structure of the fungus were analysed and 8 vegetative compatibility types were detected. The most frequent types were EU 2, EU 1, EU 12 and EU 11. Hypovirus was found in all white tested isolates. The collection of the white hypovirulent fungus ofCryphonectria parasiticastrains was established. The hypovirulent strains ofCryphonectria parasiticawill be used in further research for biological treatment of active cancers. The Experimental plot I with a stronger intensity of thinning,trees achieve larger diameters and a higher percentage of healthy trees and trees with healing cancer and smaller percentage of trees with active cancer. On the control plot, the diameter of the threes, the percentage of the healthy trees and trees with healing cancer were lower. but more trees with superficial necrosis The results indicate the need for continuing follow-up experiments and to establish a new experimental plots in order to protect the chestnut stands and increasing its quality.
