“…Harvest was known in detail for this hunting estate. Based on different aspects of wild boar development, behaviour, and diet, we assumed that new individuals begin to produce visible signs of activity by the age of 6 months [32][33][34][35].…”

Estimation of European wild boar relative abundance and aggregation: a novel method in epidemiological risk assessment

SUMMARYWild boars are important disease reservoirs. It is well known that abundance estimates are needed in wildlife epidemiology, but the expense and effort required to obtain them is prohibitive. We evaluated a simple method based on the frequency of faecal droppings found on transects (FBII), and developed a spatial aggregation index, based on the runs test statistic. Estimates were compared with hunting data, and with porcine circovirus and Aujeszky's disease virus seroprevalences and Mycobacterium tuberculosis complex and Metastrongylus spp. prevalence. The FBII and the aggregation index were correlated with the hunting index, but both of the former estimates correlated better than the latter with the disease prevalences. Hence, at least in habitats with high wild boar densities, the FBII combined with the aggregation index constitutes a cheap and reliable alternative for wild boar abundance estimation that can be used for epidemiological risk assessment, even outside the hunting season and in areas with no available data on hunting activities.

“…Also because of the diet of wild boar which depends mainly on energy-rich plants (Schley and Roper 2003), its large body size and high reproductive output (Fwenández-llario and Maeos-quesada 1998), wild boar usually causes significant damage to agriculture (e.g., Kristiansson 1985;Mackin 1970;Schley and Roper 2004;Herrero et al 2006;Linkie et al 2007). In Spain and Portugal, even in years of abundant oak (Quercus aliena var.…”

Factors affecting crop damage by wild boar and methods of mitigation in a giant panda reserve

et al. 2008

In China, following the introduction of protection measures, wild boar (Sus scrofa) are returning to forested mountains they previously inhabited and conflict in villages near or within areas under protection has intensified. We studied this phenomenon around a giant panda nature reserve in the Qinling Mountains, China to determine the incidence and frequency of wild boar damage and methods of mitigation. Over a 3-year period, we found that almost half of households in the local village sustained crop damage, that wild boar frequently raided maize (Zea mays), potato (Ipomoea batatas), and wheat (Triticum aestivum) adjoining the reserve, and that boar usually raided croplands at night and preferred the actual crops. The distance between maize fields and mountains or a stream predicted the probability of a field being raided and also the severity of the damage. Local farmers used many methods to protect their crops; however, all were ineffective except increasing the presence of humans in fields.

“…roe deer Capreolus capreolus, red deer Cervus elaphus), wild boars reach sexual maturity earlier, have a relatively short gestation period, higher litter size and short lactation period (Fernández-Llario and Mateos-Quesada 1998;Gerard et al 1991;Abáigar 1992;Dzieciolowski et al 1992;Gaillard and Jullien 1993;Rosell et al 2001). Sexual maturity in females is achieved between 5 and 10 months of age, although it is assumed that a minimum body weight of 15-35 kg (e.g.…”

Reproductive performance of wild boar females in Portugal

et al. 2010

Reproductive tracts of 214 female wild boars collected in Central Portugal between October and February over the period 1997 to 2001 were examined. From this material, we were able to determine reproductive phenology (conception and birth periods) as well as age and weight of sows at puberty, ovulation rates of adults, foetal sex ratio, levels of intrauterine mortality, final litter size and postnatal mortality. Differences between year, region, age and body weight were analysed. A total of 66.8% of the females examined were gestating or lactating and 96.3% of these weighed >40 kg. The highest proportions of pregnant sows were found in the adult age/weight classes (74%). None of the juvenile females (1 year old and younger) were lactating and only 7% was pregnant. The average number of foetuses/female (4.1±1.2SD) and that of corpora lutea per female (4.6±1.7SD) increased from lighter and younger to heavier and older wild sows. Foetal sex ratio was biased towards males (1.3:1). Observed intrauterine mortality rate (9.7%) and postnatal mortality (6.3%) were among the lowest recorded in European wild boar populations. The productivity rate of the Central Portuguese wild boar population was calculated as 1.1 young per individual in the population. Conception and birth periods did not differ significantly between the considered 4 years. Birth synchronisation was pronounced in all the years, with a peak of births occurring in March.
