“…This is in line with previous studies, which have revealed that wild boar damage is negatively correlated with the grade of anthropogenic influence (e.g. Schley et al 2008). We think that the distance to the nearest occupied building (i.e.…”

“…3). This is in line with other studies that showed grassland to be damaged at higher proportions than cereal crops and other seasonal cultures (Schley 2000, Schley et al 2008. Our result also corresponds with the yearly damage statistics of the hunting and fishing agency of the Canton Basel-Land, which amounts damage to grassland at approximately 50% of all damage caused by wild boars (unpubl.…”

Following the spread and increase of wild boar populations in Europe during the last decades, conflicts with humans have intensified also in Switzerland. Damage to crops and grassland augmented considerably and became unacceptable. Farmers and authorities are highly interested in efficient alternatives to the installation of costly and time consuming electric fences for crop protection. In the present study we investigated the effectiveness of a gustative repellent in field experiments with free-ranging wild boars in clover sowings, meadows, and wheat fields. Although we observed a slight trend towards a damage reduction, the results show, that the repellent was not able to prevent damage at a significant level. We further could not detect any area avoidance by the wild boars as a response to the repellent. On the basis of our findings we conclude that gustative repellents relying on learned avoidance as a consequence of negative experience are not a promising means for protection of crops and grassland from wild boar damage. We further discuss the effects of different agricultural crops and the anthropogenic influence on the frequency of damage.

“…In addition, several factors suggest that the trend is worrisome. In recent decades, populations of wild boar have increased in Europe (Geisser and Reyer 2004;Acevedo et al 2006;Schley et al 2008). Larger populations might lead to an increase in wild boar disturbances, which has been observed in feral pig populations in other protected mountainous areas (Hone 2002).…”

Interactions between traditional livestock management practices and wildlife activities are important in the conservation of many mountain ecosystems including the summer rangelands in the Spanish Central Pyrenees, where rooting by wild boar (Sus scrofa) is a large disturbance that can reduce the amount of area available to grazing livestock. This study explored the likely impact of wild boar rooting on Pyrenean grasslands. It quantified the extent of wild boar rooting in livestock grazing areas and determined whether wild boars selected or avoided areas depending on the type of livestock and stocking rates. Wild boar rooting affected 16% of livestock grazing area and occurred in sites that were grazed by cattle, rather than by sheep. In addition, a preference for areas that had intermediate stocking rates was found. The relationship between the increase in the number of wild boars and trends in livestock management suggests that the extent of wild boar rooting will increase especially in cattle grazing areas, and therefore, the area available for cattle grazing in Pyrenean mountain rangelands would decrease significantly.

“…In some cases, the prof itability of hunting has encouraged certain practices such as the use of artificial feeders and the legal or illegal relocation of individuals that have increased the number of boar (Wood & Barret, 1979;Spencer & Hamton, 2005). The negative effects of increases in wild boar populations include damage to crops (Herrero et al, 2006;Schley et al, 2008), traffic accidents (Rosell et al, 2001;Peris et al, 2005;Colino-Rabanal et al, 2012), and the transmission of diseases since wild boar act as a reservoir for livestock, wildlife, and human diseases such as brucellosis, tuberculosis, salmonellosis, Aujeszky's disease, and classical and African swine fever. Some of these diseases can cause direct or indirect economic losses -mortality and poorer weight gain in livestock -and oblige the implementation of disease prevention, control, and eradication programs.…”

Wild boar (Sus scrofa) populations in many areas of the Palearctic including the Iberian Peninsula have grown continuously over the last century. This increase has led to numerous different types of conflicts due to the damage these mammals can cause to agriculture, the problems they create in the conservation of natural areas, and the threat they pose to animal health. In the context of both wildlife management and the design of health programs for disease control, it is essential to know how wild boar are distributed on a large spatial scale. Given that the quantifying of the distribution of wild species using census techniques is virtually impossible in the case of large-scale studies, modeling techniques have thus to be used instead to estimate animals' distributions, densities, and abundances. In this study, the potential distribution of wild boar in Spain was predicted by integrating data of presence and environmental variables into a MaxEnt approach. We built and tested models using 100 bootstrapped replicates. For each replicate or simulation, presence data was divided into two subsets that were used for model fitting (60% of the data) and cross-validation (40% of the data). The final model was found to be accurate with an area under the receiver operating characteristic curve (AUC) value of 0.79. Six explanatory variables for predicting wild boar distribution were identified on the basis of the percentage of their contribution to the model. The model exhibited a high degree of predictive accuracy, which has been confirmed by its agreement with satellite images and field surveys.Additional key words: Sus scrofa; environmental suitability; MaxEnt; spatial distribution; wildlife management; geographic information. This work has one supplementary table and three supplementary figures that do not appear in the printed article but that accompany the paper online.Abbreviations used: AUC (area under the receiver operating characteristic curve); GAM (generalised additive models); GBIF (global biodiversity information facility); GIMMS (global inventory modeling and mapping studies); GLM (generalized linear model); GRASS (geographic resources analysis support system); MaxEnt (maximum entropy); NDVI (normalized difference vegetation index); ROC (receiver operating characteristic); SDM (species distribution model); SRTM (shuttle radar topography mission); VCF (vegetation continuous fields); VIF (variance inflated factor).
