“…Overall, our results are in line with those from other countries (Łabudzki and Wlazełko 1991;Macchi et al 1992;Geisser 2000;Linderoth and Elliger 2002). In France, damage to grassland (23%) was in second place with other cereals (23%), behind maize (43%; Klein et al 2007).…”

“…Damage to maize and to cereals occurred just after planting and from the moment seeds were present, which is in line with results reported from Spain (Herrero et al 2006), Croatia (Łabudzki and Wlazełko 1991) and Switzerland (Geisser 2000), but not Italy (Macchi et al 1992). As regards damage to grassland, most requests for compensation in Italy concerned damage in autumn (Macchi et al 1992), whereas in Luxembourg and in the UK, this type of damage occurred almost exclusively in winter (January to March; Wilson 2004; this study).…”

Patterns of crop damage by wild boar (Sus scrofa)in Luxembourg over a 10-year period

In many European countries, the wild boar (Sus scrofa) is often associated with crop damage. In this study, we analyse data relating to 13,276 cases of wild boar damage to agricultural crops over a 10-year period in Luxembourg (an area of 2,586 km 2 in Western Europe). Results show that (1) damage is more severe in this area than in others; (2) damage to permanent grassland is far more frequent and more severe than damage to annual crops; (3) trichomatous crops such as barley are avoided; (4) damage is seasonally distributed according to type of crop; (5) damage is distributed spatially in a non-uniform manner; (6) damage intensity is significantly correlated with wild boar hunting bags, both over time and space. We suggest that wild boar management strategy should always take into account the issue of damage to agricultural crops. Our results imply that measures for preventing or reducing damage should be more targeted in time and space and that adjustments to cropping patterns should contribute towards a reduction of wild boar damage.

“…In many parts of Europe, wild boar Sus scrofa L. population increase, and dispersal into new areas is accompanied by economic problems (e.g., Labudzki and Wlazelko 1991;Groot Bruinderink and Hazebroek 1996;Gortázar et al 2007). Consequently, farmers and animal health authorities call for a stringent reduction of wild boar populations (Kaden 1999;Bieber and Ruf 2005;Killian et al 2006).…”

Increasing wild boar (Sus scrofa L.) population densities all over Europe cause severe economic problems. For understanding mechanisms of epidemics, the knowledge of dispersal is required. Thus, we investigated dispersal rates and distances with regard to sex and age of wild boar in southwestern Mecklenburg-Western Pomerania. From 152 marked wild boar, 105 have been registered as dead, of which, 51% were males and 49% females. Fortyfive percent were shot as piglets, 41% as yearlings, and 14% as adults. The distance between capture site and site of death ranged between 184 m and 41.5 km. Piglets were shot closer to their capture site (mean distance 1 km) than older animals (mean 4 km), although this difference was only significant for males. In general, males tended to disperse further before being shot (3.8 km) than females (1.6 km). Only 3.8% of all animals were shot at distances larger than 10 km. As most animals (84.6%) were shot inside their natal home range, only a small proportion (15.4%) did actually disperse (shot outside mothers home range), which is 32% of all animals surviving to the age of yearlings. Of those dispersed animals, 25% were females. The low dispersal rate is biased by female philopatry and allows actual dispersal only at very high population densities or in sparsely populated regions. In consideration for the low natural mortality proved by radiotagged animals, the harvest rate is lower than the net reproduction. We did not detect any sex-biased hunting. The dominating hunting method was single hunt at bait, although drive hunts are highly effective. However, hunting rates on piglets and females were too low for regulating the population.

Evaluation of an odor repellent for protecting crops from wild boar damage

Wild boar populations have dramatically increased in the past decades and the species has spread all over Europe. As the wild boar expanded its activity range into agricultural land, conflicts with humans have intensified. Today, the damage caused by wild boar amounts to millions of dollars every year. In Switzerland, farmers usually protect fields with electric fences, which have proven to be effective in preventing damage, but are also expensive. Alternatively, various cheaper deterrents and repellents are commercially available. However, most of them lack scientific proof of efficacy. In the present study, we investigated the effectiveness of the odor repellent ''Wildschwein-Stopp Ò '' against wild boar. We conducted field experiments with free-ranging wild boars at baited luring sites, which were placed in three different regions of the Canton Basel-Land, Northwest Switzerland. The odor repellent was not able to prevent the wild boars from entering our luring sites. We recorded a minimal and nonsignificant deterrent effect of 0.4%. Our results lead to the conclusion that the repellent is ineffective and, therefore, not recommendable for crop protection. On the basis of the present study we generally doubt fear-inducing repellents to be effective against wild boars and feral pigs. Our findings may indicate seasonal variation in wild boar activity outside forests since the probability of wild boar visits at the luring sites differed according to the season. The visits at the luring sites peaked in spring and fall which coincides with the occurrence of damage to agricultural land.
