Wild Boar Paradox – Intensive Hunting Boosts Population Increase

Popis výsledku v původním jazyce

Hunting statistics affirm that the number of wild boar (Sus scrofa) has increased consistently throughout Europe over recent decades. In this model analysis, we analyzed data on hunting bags in the Czech Republic to elucidate the effects of hunter effort on wild boar population dynamics. We presumed that hunting pressure destroys the regular social system whereby reproduction of younger, subordinate females is suppressed, consequently increasing overall reproductive capacity. Data on annual hunting bags for wild boar came from the official state statistics and covered 77 districts from 27 seasons between 1993 and 2019. &quot;Change in hunting pressure&quot;, i.e. the change in the number of boar harvested in any given year as a percentage of the numbers taken in the following year, was analyzed with a multivariate Generalized Linear Mixed Model (GLMM) for repeated measures. We applied the information-theoretic approach for estimating the effects of different factors on this Change in hunting pressure, using expanded information criteria. The GLMM of the best model revealed that the change in hunting pressure was growing with increasing total hunting bags for wild boar. In contrast, with an increase in the proportion of hunted sows within the overall bag, the Change in hunting pressure decreased. Furthermore, the interaction between the Percentage of hunted sows and Hunting bags for all wild boars confirmed these opposite trends. Finally, with the increasing coldness of the district, winter precipitation, and summer temperature, the Change in hunting pressure decreased.
