Sažetak
The possibility of releasing and reintroducing artificially breaded partridges in open habitats has been researched through a period of two years, on the territories of two separate sites. During these two years 34 animals have been released from which 17 have been marked with a telemetric collar. Partridges from artificial breeding have been released in three different times of year. First release of a semi-adults has been carried out in hunting ground "Ježdovec–Stupnik" (site 1) where altogether five pairs of partridges have been released. Second release of the mother flock has been done in autumn in the territory of hunting ground "Črnovšćak" (site 2). Third release altogether and second in line has been carried out in early spring in the same territory when 16 animals have been released, and 8 marked. In the release sites preparation of habitat hasn’t been done. Telemetric collars that emit a signal every 2 seconds have been used for marking. Retention location of the released animals has been monitored and recorded on a daily basis with a radio antenna using the triangulation method. From 17 marked and released animals altogether 13 of them have been found dead after a shorter
or longer period of time. It has been determined that the length of survival of the released animal is significantly different considering the period of release. The longest survival had the animals released in summer, whereas the shortest survival had animals released in early spring. After the conducted research it can be determined that the release of partridges from artificial breeding with the purposes of creating a mother fund is questionable and it has justification only when all necessary conditions are met or in other words with a suitable habitat with a certain number of predators that won’t endanger the survival of the released animals. Optimal release time has been determined as early summer period when animals in habitat find enough food and shelter, when the climate conditions with enough water are favorable as well, on the other hand the survival problem of these animal remains after removal of agricultural crops when they become easy prey for fury and especially feather predators whose numbers cannot be directly influenced due to binding law regulations.
