During the springs of 1988 1989, experiments were conducted to determine effective methods of controlling damage by ring-necked pheasants (Phasianus coichicus) to sprouting corn in southwestern Idaho. Plot evaluations (1988) failed to demonstrate the ability of Miller Hot Sauce Animal Repellent, Isotox Seed Treater (F), provision of alternate food, and bird scaring reflective tape to reduce damage. When evaluated using entire production fields for replicates (1989) firecrackers on fuse rope, bird scaring reflective tape, hawk-kites, and provision of alternate food all significantly reduced the number of seedlings disturbed by ring-necked pheasants. No treatment in either experiment significantly increased the number of surviving corn seedlings. Fields were damaged from germination until the average sprout height exceeded 10 cm, but damage was greatest (69%) when sprouts were less than 5 cm tall. Management recommendations to avert damage include establishing treatments prior to the onset of damage and avoiding early planting dates. / Graduation date: 1991

The diploma thesis deals with the comparison of the number of the hunted pheasants. The purpose of this thesis is to evaluate the quality of care of reared pheasants depending on the amount of pieces reared during the year. The first case is about hunting in the land registry of Hosín and the amount of 3000 released pheasants, which are hunted in fee huntings. In the second case, the amount of pheasants is about 650 pieces and they are intended for member huntings. In both cases the conditions for rearing were similar and they met the welfare requirements. The released individuals were in good physical condition. Next part of this thesis is about the pheasantry in Chlum u Třeboně. In this facility 9000 pheasants are repeatly released and 6000 of them are caught. The area is similar to pheasantry in Hosín. The third subject of observation is the pheasantry Vrbenské rybníky. The amount of released and catched pheasants is similar to the pheasantry in Chlum u Třeboně, but there is a difference in the location of pheasantry. The results showed that the number of hunted pieces is higher when the number of reared pheasants is lower, and there were better results in pheasantries which are situated further from human aglomerations. Data was gained from personal records of controllers or administrations of pheasantries who were in function in a given period.

The study is dealing with appreciation of natural reproduction of ring-necked Pheasant (Phasianus colchicus) in a pheasantry owned by LČR,s.p. By one of the purpose was set the appreciation of the pheasantry and current natural conditions in accordance with public notice no.7/2003 in a full range. The background of the pheasantry is complied with requirements by the public notice. Another objective was monitoring running of Pheasant males. Next objective was to analysed and evaluated a natural reproduction ability of Pheasant females in the pheasantry. There was found very low ability of reproduction in the pheasantry. As the main reasons for low reproduction ability of Pheasant females were found mostly higher population pressure of predators and depressed ability of making nests by Pheasant females of intensive artificial breeding.
