“…Additionally, in special scenarios a moribund animal may be forced to leave its core home-range by by intensive drive hunts (expert scenario). This could cause the animal to move further away (Sodeikat and Pohlmeyer, 2003). Thus their carcass finally will be in contact with more distant wild boar groups.…”

ASF is a devastating infectious disease of domestic pigs and wild boar, usually fatal. No vaccine exists to combat this virus. It does not affect humans nor does it affect any animal species other than members of the Suidae family. From the beginning of 2014 ASF has spread in Estonia, Latvia, Lithuania and Poland, mainly in the wild boar, causing very serious concerns. The European Commission requested EFSA to assess different wild boar management options taking into consideration its ecology in the Baltic States and Poland. Therefore, a simulation study was performed comparing control strategy alternatives using a spatio-temporally explicit individual-based model. The model was developed based on literature regarding wild boar ecology; ethology of the ASF virus recently circulating in Eastern Europe; wild boar density maps from the ASF affected regions and an expert consultation meeting. The model results did not reveal one single immediately effective control measure based on accepted wild boar management tools. Strategies using conventional wild boar management approaches -ban of feeding and targeted hunting of reproductive females -were found to become effective slowly over multiple generations of reproduction. Therefore, when applying the strategies, a width of 100-200km is required as buffer zone surrounding the area with ASF detections in order to compensate the forward spread till measures become effective. Massive population destruction (i.e. about 80% of the population in the control area within 4 months with any available technique) or instantaneous removal of infectious carcasses could stop ASF spread already by limited buffer width of below 50km. The equal outcome is reasoned by the avoidance of infectious carcasses when the population was destroyed. Centred on the effective and immediate exclusion of wild boar contacts with infectious carcasses, hybrid strategies including reasonably intensified conventional hunting may suffice to stop ASF spread using a practical buffer width (about 50km) resp. time horizon (less than 3 years) for control while avoiding destructive measures.

“…Due to preadaptation wild boar will recognize domestic dogs as predators (Nores et al, 2008) belonging to their urban landscape of fear. In rural environments domestic dogs are used in wild boar hunting to this date (Sodeikat and Pohlmeyer, 2003). Consequently, all domestic dogs will be perceived as persisting threat and areas with a high density of dogs represent a landscape of fear.…”

Secrets of Success in a Landscape of Fear: Urban Wild Boar Adjust Risk Perception and Tolerate Disturbance

et al. 2017

In urban areas with a high level of human disturbance, wildlife has to adjust its behavior to deal with the so called "landscape of fear." This can be studied in risk perception during movement in relation to specific habitat types, whereby individuals trade-off between foraging and disturbance. Due to its high behavioral plasticity and increasing occurrence in urban environments, wild boar (Sus scrofa) is an excellent model organism to study adjustment to urbanization. With the help of GPS tracking, space use of 11 wild boar from Berlin's metropolitan region was analyzed: we aimed at understanding how animals adjust space use to deal with the landscape of fear in urban areas compared to rural areas. We compared use vs. availability with help of generalized linear mixed models. First, we studied landscape types selected by rural vs. urban wild boar, second, we analyzed distances of wild boar locations to each of the landscape types. Finally, we mapped the resulting habitat selection probability to predict hotspots of human-wildlife conflicts. A higher tolerance to disturbance in urban wild boar was shown by a one third shorter flight distance and by an increased re-use of areas close to the trap. Urban wild boar had a strong preference for natural landscapes such as swamp areas, green areas and deciduous forests, and areas with high primary productivity, as indicated by high NDVI (normalized difference vegetation index) values. The areas selected by urban wild boar were often located closely to roads and houses. The spatial distribution maps show that a large area of Berlin would be suitable for urban wild boar but not their rural conspecifics, with the most likely reason being a different perception of anthropogenic disturbance. Wild boar therefore showed considerable behavioral plasticity suitable to adjust to human-dominated environments in a potentially evolutionarily adaptive manner.

“…When agricultural fields were available, wild pigs were most comfortable in the edge areas between forests and fields where they have easy access to both food and hiding places. This causes them to be in constant conflict terms with the humans, having deleterious effects as documented by Sodeikat and Pohlmeyer [2,4,18]. The protective advantage of the forest was essential for these animals and resting places and breeding nests were always located in areas of dense vegetation where they feel safe and are protected from bad weather.…”

“…There was a tendency for wild pig home ranges to be bordered by manmade or natural topographic features. The use of the area encompassed by the home range is localized or patchy, with the different parts of their home range being connected by a network of paths which are regularly used [6,15,18,42]. These network paths are very common in the study area as tea/crop plantations are provided with paths, these were utilized by the pigs to navigate a geographical area.…”

Wild pigs are the most prolific, very intelligent and secretive species that over the recent past has been in a lot of conflict terms with the humans. These animals are adaptive generalists and survive in wide range of habitats worldwide. The reproductive traits of wild pigs are extraordinary showing high prolificacy so it becomes impossible to control their population. These animals have adapted to become nocturnal proving it difficult to know about their behavior. However in order in spite of these challenges the main objectives of this study was to understand the behavior and ecology of this particular species to come up the control strategies. Thus basis for documenting and understanding the wild pig behavior has dramatically evolved, contributing significantly to our understanding of these animals. In general, however, the lack of intensive field studies was attributed to the fact that wild pigs were regarded everywhere as a pest. The wild pig groups usually known as sounder's were tracked and all findings were documented. The study period was about a year and the wild pigs were tracked and observed at the adjoining regions of the Eastern Ghats (Sathyamangalam region) and the Western Ghats (Mudumalai tiger reserve, Anaimalai tiger reserve) and of Tamil Nadu state during November, 2012 to October, 2014. A variety of behaviors were documented such as social unit organization, Habitat utilization, Daily activity patterns, Movement patterns, Modes of mobility, Home range, Male-male competition, Maternal behavior, Resting/loafing beds, Mannerism and attitudes, Vigilance behavior, Vocalizations, Wallowing, Rubbing, Symbiotic grooming behavior, Scent marking, Senses. At the end of the study we were able to precisely outlay the above the entire behavior attributes of wild pigs. These findings are necessary to understand the wild pigs and their vermin nature to combat crop raiding, eventually cutting down Human-Wild pig conflict, that will a more scientific method of conservation to avoid conflicts ending in tragic outcomes.
