Gortázar, R. Villafuerte, María Martín] Erfolg traditioneller Rothuhnauswilderungen zur Niederwildaufstockung in Gebieten mit geringer Populationsdichte in Spaniens Nordosten Aragón Summary: Release of pen-reared red-legged partridges(Alectoris rufa) is a common game management tool in Spain. In spite of three million partridges raised yearly in captivity, at present time, effectiveness of traditional restocking has received little research. Consequently, we investigated the survival of 62 radio-tagged partridges under two different release conditions: scattered and grouped, imitating for our purposes the procedure employed by Spanish hunters and gamekeepers. The null-hypothesis of no difference between the survival probabilities observed in the grouped versus disperse releases was rejected (p = 0.019). In both experiences, 25 to 34 % of the mortality took place in the first 72 hours after release. Thereafter, the average survival of the disperse-released partridges was clearly higher than those of the grouped ones, with 37.4 ± 1.8 % of the former surviving the first month in comparison to only 5.8 ± 1.1 % of the latter (figure). Red fox(Vulpes vulpes) and golden eagle(Aquila chrysaëtos) were suspected predators in 37 of 39 kills (95 %). Traditional restocking of red-legged partridges in Spain is not an effective management tool to enhance wild populations. In any case, the technique may be improved by scattering the release sites.
