Population Structure of Wild Boar (Sus Scrofa) in the Czech Republic

Popis výsledku v původním jazyce

Sex ratio, age and social structure are the key factors for the growth and development of all animal populations with sexual reproduction. In the case of wild boar under Central European conditions, the population structure plays a significant role in favour of its population growth and density. Despite obtaining historically high numbers of hunted boars in recent years, we are still not successful in wild boar population reduction in free range hunting grounds. In our study, we focused on the evaluation of the sex and age structure in selected wild boar populations in two unfenced hunting grounds (UHG) and in one private hunting preserve (PHP) during the main reproductive season. The criteria for localities selection were: the absence of individual boar hunting during the year and hunting only by common hunts (battues). The age and sex were evaluated for all hunted boars from October to the end of January in three seasons (2015/2016, 2016/2017 and 2017/2018). In total, 665 wild boar (UHG: 416 indd, PHP: 249 indd), of which 58% were females, were examined. The primary sex ratio in all localities was about 1:1.17 (in favour of females). In the case of yearlings, the ratio of sex was 1:1.86 in FHG (again in favour of females) and 1:0.75 in PHP (in favour of males). The predominance of females in PHP is the result of the ease of successfully-hunting males that have been excluded from the sounder (to avoid inbreeding). The absence of the yearling-females in PHP is the result of their being selectively protected (in a breeding enclosure) in a non-hunted area of the PHP For boar over 2 years of age, the sex ratio was 1:3.55 in UHG (in favour of females) and 0:1 in PHP (as adult males were hunted in advance to ensure the safety for hunting dogs and hunters). Females dominated in all age ranges of the wild boar population, reflecting the current population boom in Central Europe. This is the result of inappropriate wildlife management, especially inadequate regulatory pressure upon reproductively active females.
