The thesis concentrates on assessment of mouflon population and it's habitat. The survey revealed that the mouflons had consumed 0,3% of herbaceous and grass biomass and 1,2% of timber biomass during the growing season. Outside the growing season the lack of natural feed was compensated by the good quality care taken by gamekeepers. The number of 30 animals in the population was estimated by combination of different measuring methods. The damage caused to young spruce trees proved to be the most dangerous influence that the mouflons have on woodlands. The quality of mouflon game was assessed by measuring the horns according to the CIC standards and by craniometric measuring of the heads and was found to be above-average. There are no health problems within the population. The local environment is very suitable for keeping mouflon game.
