Just then, a young boar passed by and the hunter stabbed him to death. At some point in the distant past, an animal – whether it was a wolf, a wild ox, a jungle bird or a wild boar – began to walk on a path that ended with trust or even trust in people. On the islands of Komodo and Rinca, wild boar inhabits mainly savannah or open monsoon forests and avoids heavily forested areas unless it is pursued by humans. [11] Wild boars are known as competent swimmers capable of travelling long distances. In 2013, it was reported that a wild boar had completed the 11-kilometer (7-mile) swim of the France in Alderney in the Channel Islands. Due to concerns about the disease, he was shot and burned. [49] The species was originally found in North Africa and large parts of Eurasia; from the British Isles to Korea and the Sunda Islands. The northern limit of its range stretched from southern Scandinavia to southern Siberia and Japan. In this area, it was missing only in extremely dry deserts and alpine areas. It was once found in North Africa along the Nile Valley to Khartoum and north of the Sahara.
The species is found on some Ionian and Aegean islands and sometimes swims between islands. [64] The reconstructed northern border of the Asian Animal Range stretched from Lake Ladoga (at 60° N) through the Novgorod and Moscow region to the south of the Urals, where it reached 52° N. From there, the border headed towards Ishim and further east to the Irtysh at 56° N. In the eastern steppe of Baraba (near Novosibirsk), the border turned steeply south, circling the Altai Mountains and heading east again, including the Tannu-Ola Mountains and Lake Baikal. From there, the border stretched a little north of Amur eastward to its lower course on the Sea of Okhotsk. On Sakhalin there are only fossil reports of wild boars. The southern borders of Europe and Asia were almost invariably identical to the coasts of these continents. It is absent in the arid regions of Mongolia from 44 to 46°N south, in China west of Sichuan and in India north of the Himalayas. It is absent in the higher altitudes of the Pamirs and Tian Shan, although they occur in the Tarim Basin and on the lower slopes of the Tien Shan. [3] The wild boar (Sus scrofa), also known as the wild boar[3], the common boar[4], the Eurasian boar[5], or simply the wild boar[6], is a suid native to much of Eurasia and North Africa and introduced to the Americas and Oceania. The species is today one of the most widespread mammals in the world, as well as the most widespread suiform. [4] It has been classified as the Least Concern on the IUCN Red List because of its long range, high numbers and adaptability to a variety of habitats.
[1] It has become an invasive species in part of its introduced range. Wild boars probably originated in Southeast Asia in the early Pleistocene[7] and surpassed other Suid species when they spread to the Old World. [8] Wild boars of unknown origin were stored on a ranch on the Edwards Plateau in the 1940s, only to escape during a storm and hybridize with local populations of wild boar that then spread to nearby counties. [80] Wild boars cause many habitats to become less diverse due to their feeding behaviour and predation. Wild boars dig up eggs of species and eat them, as well as kill other wild animals for food. When these wild boars compete with other species for resources, they usually succeed. [90] A study published in the Journal of Experimental Marine Biology and Ecology was conducted on the results of Feral Swine Control. Just two years after control began, the number of turtle nests increased from 57 to 143, and the percentage of turtle nest predators increased from 74 to 15. [91] They kill and eat deer, lizards, birds, snakes and more.
These wild boars are called «opportunistic omnivores,» which means they eat almost anything. This means they can survive almost anywhere. A large excess of food and the ability to adapt to each new place causes a lot of reproduction. All these factors make it difficult to eliminate wild boars. [92] Wild boars also tend to transmit diseases and many pathogens. It also contributes to the decline of biodiversity. The wolf (Canis lupus) is the main predator of wild boar in most areas of its range. A single wolf can kill about 50-80 wild boars of different ages in a year. [3] In Italy[55] and in the Belarusian National Park of Belovezhskaya Pushcha, wild boars are the main prey of the wolf, despite an abundance of alternative, less powerful ungulates.
[55] Wolves are particularly dangerous in winter, when deep snow hinders the movement of wild boars. In the Baltic regions, heavy snowfall can allow wolves to almost completely eliminate wild boars from an area. Wolves mainly target piglets and subadults and rarely attack adult sows. Adult males are usually completely rejected. [3] Dholes (Cuon alpinus) can also hunt wild boars, to the point that they keep their numbers low in northwestern Bhutan, although there are many more cattle in the area. [56] The kitchen prepares fresh pasta with local porcini mushrooms, truffles, wild boars, various grilled main dishes with flavors such as juniper, and old-school classics such as fried veal cutlets. Boars are usually social animals that live in echo sounders dominated by females, consisting of sterile sows and mothers with young led by an old matriarch. Male wild boars leave their sonar at the age of 8 to 15 months, while females stay with their mothers or establish new areas nearby. Subadult males can live in tightly knit groups, while adult and older males tend to be alone outside the breeding season. [9] [a] In 1990, up to 16 subspecies were recognized, divided into four regional groups based on skull height and length of tear bones. [2] The species lives in matriarchal societies composed of interconnected females and their young (males and females). Adult males are usually solitary outside the breeding season.
[9] The wolf is the main predator of wild boar in most of its natural range, except in the Far East and the small Sunda Islands, where it is replaced by the tiger and Komodo dragon, respectively. [10] [11] Wild boar has a long history of association with humans, as it has been the ancestor of most domestic pig breeds and big game for thousands of years.
