The species is now one of the widest-ranging mammals in the world, as well as the most widespread [[Suina|suiform]].<ref name="oliver1993" /> It has been assessed as [[least concern]] on the [[IUCN Red List]] due to its wide range, high numbers, and adaptability to a diversity of habitats.<ref name=iucn/> It has become an [[invasive species]] in part of its introduced range. Wild boars probably originated in [[Southeast Asia]] during the [[Early Pleistocene]]<ref name=chen2007 /> and outcompeted other suid species as they spread throughout the [[Old World]].<ref name=kurten1968 />

{{As of|2005}}, up to 16 [[subspecies]] are recognized, which are divided into four regional groupings based on skull height and [[lacrimal bone]] length.<ref name=msw3 /> The species lives in matriarchal societies consisting of interrelated females and their young (both male and female). Fully grown males are usually solitary outside the [[breeding season]].<ref name="marsan75" /> The [[wolf]] is the wild boar's main predator in most of its natural range except in the [[Far East]] and the [[Lesser Sunda Islands]], where it is replaced by the [[tiger]] and [[Komodo dragon]] respectively.<ref name="baskin2003">{{cite book |last1=Baskin |first1=L. |last2=Danell |first2=K. |year=2003 |title=Ecology of Ungulates: A Handbook of Species in North, Central, and South America, Eastern Europe and Northern and Central Asia |publisher=[[Springer Science & Business Media]] |pages=15–38 |isbn=3-540-43804-1}}</ref><ref name="auffenberg1981">{{cite book |last=Affenberg |first=W. |year=1981 |title=The Behavioral Ecology of the Komodo Monitor |publisher=[[University Press of Florida]] |page=248 |isbn=0-8130-0621-X}}</ref> The wild boar has a long history of association with [[human]]s, having been the ancestor of most [[domestic pig]] breeds and a [[Big-game hunting|big-game animal]] for millennia. Boars have also re-[[Hybrid (biology)|hybridized]] in recent decades with [[feral pig]]s; these [[boar–pig hybrid]]s have become a serious pest wild animal in the [[Americas]] and [[Australia]].

== Terminology ==
As true wild boars became extinct in [[Great Britain]] before the development of [[Modern English]], the same terms are often used for both true wild boar and pigs, especially large or semi-wild ones. The [[English language|English]] [[:wikt:boar#English|''boar'']] stems from the [[Old English]] {{lang|ang|[[:wikt:bar#Old English|bār]]}}, which is thought to be derived from the [[West Germanic languages|West Germanic]] {{lang|gmw|[[:wikt:Reconstruction:Proto-West Germanic/bair#Proto-West Germanic|bair]]}}, of unknown origin.<ref>{{cite web |url=http://www.etymonline.com/index.php?term=boar |title=Online Etymological Dictionary |access-date=2014-10-08 |archive-date=18 October 2014 |archive-url=https://web.archive.org/web/20141018125533/http://www.etymonline.com/index.php?term=boar |url-status=live }}</ref> ''Boar'' is sometimes used specifically to refer to males, and may also be used to refer to male domesticated pigs, especially breeding males that have not been castrated.<ref>{{cite web |url=https://www.merriam-webster.com/dictionary/boar |title=boar |author=<!--Not stated--> |date= |website=Merriam-Webster Dictionary |publisher= |access-date=21 November 2023 |quote= |archive-date=29 June 2023 |archive-url=https://web.archive.org/web/20230629152128/https://www.merriam-webster.com/dictionary/boar |url-status=live }}</ref><ref>{{cite web |url=https://dictionary.cambridge.org/dictionary/english/boar |title=boar |author=<!--Not stated--> |date= |website=Cambridge Dictionary |publisher=Cambridge University Press |access-date=21 November 2023 |quote= |archive-date=17 February 2024 |archive-url=https://web.archive.org/web/20240217045345/https://dictionary.cambridge.org/dictionary/english/boar |url-status=live }}</ref>

''Sow'', the traditional name for a female, again comes from Old English and Germanic; it stems from [[Proto-Indo-European language|Proto-Indo-European]], and is related to the [[Latin]] [[:wikt:sus#Latin|sus]] and [[Ancient Greek]] [[:wikt:ὗς#Ancient Greek|''hus'']], and more closely to the [[New High German]] {{lang|de|[[:wikt:Sau#German|Sau]]}}. The young may be called ''piglets'' or ''boarlets''.<ref>{{Cite news|last=Magnier|first=Eileen|date=2020-05-07|title=Wild boarlets born in Donegal believed to be first in 800 years|work=[[RTÉ]]|url=https://www.rte.ie/news/ulster/2020/0505/1136581-boarlets-donegal/|access-date=2021-05-13|archive-date=13 May 2021|archive-url=https://web.archive.org/web/20210513213330/https://www.rte.ie/news/ulster/2020/0505/1136581-boarlets-donegal/|url-status=live}}</ref>

The animals' specific name [[:wikt:scrofa#Latin|''scrofa'']] is [[Latin]] for 'sow'.<ref>{{cite web |url=http://www.latin-dictionary.net/definition/34362/scrofa-scrofae |title=Latin Dictionary and Grammar Resources |access-date=2014-10-08 |archive-date=17 October 2014 |archive-url=https://web.archive.org/web/20141017061011/http://www.latin-dictionary.net/definition/34362/scrofa-scrofae |url-status=live }}</ref>

=== Hunting ===
In hunting terminology, boars are given different designations according to their age:<ref name="cabanau24">{{Harvnb|Cabanau|2001|pp=24}}</ref>

=== Subspecies ===

''A Natural History of Domesticated Mammals'', Cambridge University Press, pp. 91–99, {{ISBN|0-521-63495-4}}</ref>]]
{{As of|2005}}, 16 subspecies are recognised, which are divided into four regional groupings:<ref name=msw3 />
* '''Western:''' Includes ''S. s. scrofa'', ''S. s. meridionalis'', ''S. s. algira'', ''S. s. attila'', ''S. s. lybicus'', ''S. s. majori'' and ''S. s. nigripes''. These subspecies are typically high-skulled (though ''lybicus'' and some ''scrofa'' are low-skulled), with thick underwool and (excepting ''scrofa'' and ''attila'') poorly developed [[Mane (horse)|manes]].<ref name="groves1993">Groves, C.

IUCN/SSC Pigs and Peccaries Specialist Group, {{ISBN|2-8317-0141-4}}</ref>
* '''Indian:''' Includes ''S. s. davidi'' and ''S. s. cristatus''. These subspecies have sparse or absent underwool, with long manes and prominent bands on the snout and mouth. While ''S. s. cristatus'' is high-skulled, ''S. s. davidi'' is low-skulled.<ref name="groves1993" />
* '''Eastern:''' Includes ''S. s. sibiricus'', ''S. s. ussuricus'', ''S. s. leucomystax'', ''S. s. riukiuanus'', ''S. s. taivanus'' and ''S. s. moupinensis''. These subspecies are characterised by a whitish streak extending from the corners of the mouth to the lower jaw. With the exception of ''S. s. ussuricus'', most are high-skulled. The underwool is thick, except in ''S. s. moupinensis'', and the mane is largely absent.<ref name="groves1993" />
* '''Indonesian:''' Represented solely by ''S. s. vittatus'', it is characterised by its sparse body hair, lack of underwool, fairly long mane, a broad reddish band extending from the muzzle to the sides of the neck.<ref name="groves1993" /> It is the most [[Basal (phylogenetics)|basal]] of the four groups, having the smallest relative brain size, more primitive dentition and unspecialised cranial structure.<ref name="hemmer1990">Hemmer, H.

[[DNA]] evidence from sub-fossil remains of teeth and jawbones of Neolithic pigs shows that the first domestic pigs in Europe had been brought from the Near East. This stimulated the domestication of local European wild boars, resulting in a third domestication event with the Near Eastern genes dying out in European pig stock. Modern domesticated pigs have involved complex exchanges, with European domesticated lines being exported in turn to the ancient Near East.<ref>[http://news.bbc.co.uk/2/hi/science/nature/6978203.stm BBC News, "Pig DNA reveals farming history"] {{Webarchive|url=https://web.archive.org/web/20170201185510/http://news.bbc.co.uk/2/hi/science/nature/6978203.stm |date=1 February 2017 }} 4 September 2007.

== Description ==
[[File:WildBoarSkull.JPG|thumb|The skull of a wild boar]]
[[File:Animaldentition susscrofa.png|thumb|Dentition, as illustrated by Charles Knight]]
The wild boar is a bulky, massively built suid with short and relatively thin legs. The trunk is short and robust, while the hindquarters are comparatively underdeveloped. The region behind the shoulder blades rises into a hump and the neck is short and thick to the point of being nearly immobile. The animal's head is very large, taking up to one-third of the body's entire length.<ref name=heptner1988 /> The structure of the head is well suited for digging. The head acts as a plough, while the powerful neck muscles allow the animal to upturn considerable amounts of soil:<ref name="marsan70">{{Harvnb|Marsan|Mattioli|2013|pp=70–72}}</ref> it is capable of digging {{convert|8|-|10|cm|in|abbr=on}} into frozen ground and can upturn rocks weighing {{convert|40|-|50|kg|lb|abbr=on}}.<ref name=baskin2003 /> The eyes are small and deep-set and the ears long and broad. The species has well developed [[canine teeth]], which protrude from the mouths of adult males. The medial hooves are larger and more elongated than the lateral ones and are capable of quick movements.<ref name=heptner1988 /> The animal can run at a maximum speed of 40&nbsp;km/h (25&nbsp;mph) and jump at a height of {{convert|140|-|150|cm|in|abbr=on}}.<ref name=baskin2003 />

[[Sexual dimorphism]] is very pronounced in the species, with males being typically 5–10% larger and 20–30% heavier than females. Males also sport a mane running down the back, which is particularly apparent during autumn and winter.<ref name="marsan26">{{Harvnb|Marsan|Mattioli|2013|pp=26}}</ref> The canine teeth are also much more prominent in males and grow throughout life. The upper canines are relatively short and grow sideways early in life, though they gradually curve upwards. The lower canines are much sharper and longer, with the exposed parts measuring {{convert|10|-|12|cm|in|abbr=on}} in length. In the breeding period, males develop a coating of [[subcutaneous tissue]], which may be {{convert|2|-|3|cm|in|abbr=on}} thick, extending from the shoulder blades to the rump, thus protecting vital organs during fights. Males sport a roughly chicken egg–sized sac of unclear function near the opening of the penis that collects urine and emits a sharp odour.<ref name=heptner1988 />
[[File:PigSkelLyd2.png|thumb|Skeleton, as illustrated by [[Richard Lydekker]].]]
[[File:Hoffmann, Hans - A Wild Boar Piglet - 1578.jpg|thumb|A European wild boar piglet, painted by [[Hans Hoffmann (painter)|Hans Hoffman]] in 1578. Note the stripes, a characteristic feature of piglets.]]
Adult size and weight is largely determined by environmental factors; boars living in arid areas with little productivity tend to attain smaller sizes than their counterparts inhabiting areas with abundant food and water. In most of [[Europe]], males average {{convert|75|-|100|kg|lb|abbr=on}} in weight, {{convert|75|-|80|cm|in|abbr=on}} in shoulder height and {{convert|150|cm|in|abbr=on}} in body length, whereas females average {{convert|60|-|80|kg|lb|abbr=on}} in weight, {{convert|70|cm|in|abbr=on}} in shoulder height and {{convert|140|cm|in|abbr=on}} in body length. In Europe's [[Southern Europe|Mediterranean regions]], males may reach average weights as low as {{convert|50|kg|lb|abbr=on}} and females {{convert|45|kg|lb|abbr=on}}, with shoulder heights of {{convert|63|-|65|cm|in|abbr=on}}. In the more productive areas of [[Eastern Europe]], males average {{convert|110|-|130|kg|lb|abbr=on}} in weight, {{convert|95|cm|in|abbr=on}} in shoulder height and {{convert|160|cm|in|abbr=on}} in body length, while females weigh {{convert|95|kg|lb|abbr=on}}, reach {{convert|85|-|90|cm|in|abbr=on}} in shoulder height, and reach {{convert|145|cm|in|abbr=on}} in body length. In [[Western Europe|Western]] and [[Central Europe]], the largest males weigh {{convert|200|kg|lb|abbr=on}} and females {{convert|120|kg|lb|abbr=on}}. In Northeastern Asia, large males can reach [[brown bear]]-like sizes, weighing {{convert|270|kg|lb|abbr=on}} and measuring {{convert|110|-|118|cm|in|abbr=on}} in shoulder height. Some adult males in [[Primorsky Krai]] and [[Manchuria]] have been recorded to weigh {{convert|300|-|350|kg|lb|abbr=on}} and measure {{convert|125|cm|in|abbr=on}} in shoulder height. Adults of this size are generally immune from wolf predation.<ref name="marsan28">{{Harvnb|Marsan|Mattioli|2013|pp=28}}</ref> Such giants are rare in modern times, as past overhunting has prevented animals from attaining their full growth.<ref name=heptner1988 />

The winter coat consists of long, coarse bristles underlaid with short brown downy fur. The length of these bristles varies along the body, with the shortest being around the face and limbs and the longest running along the back. These back bristles form the aforementioned mane prominent in males and stand erect when the animal is agitated. Colour is highly variable; specimens around [[Lake Balkhash]] are very lightly coloured, and can even be white, while some boars from [[Belarus]] and Ussuriland can be black. Some subspecies sport a light-coloured patch running backward from the corners of the mouth. Coat colour also varies with age, with piglets having light brown or rusty-brown fur with pale bands extending from the flanks and back.<ref name=heptner1988 />

The wild boar produces a number of different sounds which are divided into three categories:
* '''Contact calls''': Grunting noises which differ in intensity according to the situation.<ref name="cabanau29">{{Harvnb|Cabanau|2001|pp=29}}</ref> Adult males are usually silent, while females frequently grunt and piglets whine.<ref name=heptner1988 /> When feeding, boars express their contentment through purring. Studies have shown that piglets imitate the sounds of their mother, thus different litters may have unique vocalisations.<ref name="cabanau29" />

Pigs are one of four known mammalian taxa which possess mutations in the [[nicotinic acetylcholine receptor]] that protect against snake venom. [[Mongoose]]s, [[honey badger]]s, [[hedgehog]]s, and pigs all have modifications to the receptor pocket which prevents the [[snake venom]] [[Snake venom#Neurotoxins|α-neurotoxin]] from binding. These represent four separate, independent mutations.<ref>{{cite journal|last1=Drabeck|first1=D.H.|last2=Dean|first2=A.M.|last3=Jansa|first3=S.A.|title=Why the honey badger don't care: Convergent evolution of venom-targeted nicotinic acetylcholine receptors in mammals that survive venomous snake bites.|journal=Toxicon|date=1 June 2015|volume=99|pages=68–72|doi=10.1016/j.toxicon.2015.03.007|pmid=25796346|bibcode=2015Txcn...99...68D }}</ref>

== Social behaviour and life cycle ==
Boars are typically social animals, living in [[Matriarchy|female-dominated]] sounders consisting of barren sows and mothers with young led by an old matriarch. Male boars leave their sounder at the age of 8–15 months, while females either remain with their mothers or establish new territories nearby. Subadult males may live in loosely knit groups, while adult and elderly males tend to be solitary outside the breeding season.<ref name="marsan75">{{Harvnb|Marsan|Mattioli|2013|pp=75–76}}</ref>{{efn|It is from the male boar's solitary habits that the species gets its name in numerous [[Romance language]]s. Although the [[Latin language|Latin]] word for 'boar' was {{lang|la|aper}}, the [[French language|French]] {{lang|fr|sanglier}} and [[Italian language|Italian]] {{lang|it|cinghiale}} derive from {{lang|la|singularis porcus}}, which is Latin for 'solitary pig'.<ref name="scheggi20">{{Harvnb|Scheggi|1999|pp=20–22}}</ref>}}

The {{visible anchor|breeding|Breeding}} period in most areas lasts from November to January, though most mating only lasts a month and a half. Prior to mating, the males develop their subcutaneous armour in preparation for confronting rivals. The [[testicles]] double in size and the glands secrete a foamy yellowish liquid. Once ready to reproduce, males travel long distances in search of a sounder of sows, eating little on the way. Once a sounder has been located, the male drives off all young animals and persistently chases the sows. At this point, the male fiercely fights potential rivals.<ref name=heptner1988 /> A single male can mate with 5–10 sows.<ref name=baskin2003 /> By the end of the rut, males are often badly mauled and have lost 20% of their body weight,<ref name=heptner1988 /> with bite-induced injuries to the penis being common.<ref>{{cite journal |last1 = Weiler |first1 = Ulrike |display-authors=etal |year = 2016 |title = Penile Injuries in Wild and Domestic Pigs |journal = Animals |volume = 6 |issue = 4 |page = 25 |doi = 10.3390/ani6040025 |pmid = 27023619 |pmc = 4846825 |doi-access = free }}</ref> The [[gestation period]] varies according to the age of the expecting mother. For first-time breeders, it lasts 114–130 days, while it lasts 133–140 days in older sows. Farrowing occurs between March and May, with litter sizes depending on the age and nutrition of the mother.

Newborn piglets weigh around 600–1,000 grams, lacking underfur and bearing a single milk incisor and canine on each half of the jaw.<ref name=heptner1988 /> There is intense competition between the piglets over the most milk-rich nipples, as the best-fed young grow faster and have stronger constitutions.<ref name="marsan83" /> The piglets do not leave the lair for their first week of life. Should the mother be absent, the piglets lie closely pressed to each other. By two weeks of age, the piglets begin accompanying their mother on her journeys. Should danger be detected, the piglets take cover or stand immobile, relying on their camouflage to keep them hidden. The neonatal coat fades after three months, with adult colouration being attained at eight months. Although the [[lactation]] period lasts 2.5–3.5 months, the piglets begin displaying adult feeding behaviours at the age of 2–3 weeks. The [[Permanent teeth|permanent dentition]] is fully formed by 1–2 years. With the exception of the canines in males, the teeth stop growing during the middle of the fourth year. The canines in old males continue to grow throughout their lives, curving strongly as they age. Sows attain [[sexual maturity]] at the age of one year, with males attaining it a year later. However, [[estrus]] usually first occurs after two years in sows, while males begin participating in the rut after 4–5 years, as they are not permitted to mate by the older males.<ref name=heptner1988 /> The maximum lifespan in the wild is 10–14 years, though few specimens survive past 4–5 years.<ref name="marsan87">{{Harvnb|Marsan|Mattioli|2013|pp=87–90}}</ref> Boars in captivity have lived for 20 years.<ref name=baskin2003 />

[[File:Wild Boar Habbitat 2.jpg|thumb|Wild boars frequently wallow in mud, possibly to regulate temperature or remove parasites]]
The wild boar inhabits a diverse array of [[habitat]]s from boreal [[taiga]]s to [[desert]]s.<ref name=heptner1988 /> In mountainous regions, it can even occupy [[Alpine climate|alpine]] zones, occurring up to {{cvt|1900|m|ft}} in the [[Carpathians]], {{cvt|2600|m|ft}} in the [[Caucasus]] and up to {{cvt|3600|-|4000|m|ft}} in the mountains in [[Central Asia]] and [[Kazakhstan]].<ref name=heptner1988 /> In order to survive in a given area, wild boars require a habitat fulfilling three conditions: heavily brushed areas providing shelter from predators, water for drinking and bathing purposes and an absence of regular snowfall.<ref name="marsan55" />

The main habitats favored by boars in [[Europe]] are [[Temperate deciduous forest|deciduous]] and [[Temperate broadleaf and mixed forest|mixed forests]], with the most favorable areas consisting of forest composed of [[oak]] and [[beech]] enclosing [[marsh]]es and [[meadow]]s. In the [[Białowieża Forest]], the animal's primary habitat consists of well-developed [[Broad-leaved tree|broad-leaved]] and mixed forests, along with marshy mixed forests, with [[Pinophyta|coniferous]] forests and undergrowths being of secondary importance. Forests made up entirely of oak groves and beeches are used only during the fruit-bearing season. This is in contrast to the Caucasian and [[Transcaucasia]]n mountain areas, where boars will occupy such fruit-bearing forests year-round. In the mountainous areas of the [[Russian Far East]], the species inhabits [[Pine|nutpine]] groves, hilly mixed forests where [[Mongolian oak]] and [[Korean pine]] are present, swampy mixed taiga and coastal oak forests. In [[Transbaikal]]ia, boars are restricted to river valleys with nut pine and shrubs. Boars are regularly encountered in [[pistachio]] groves in winter in some areas of [[Tajikistan]] and [[Turkmenistan]], while in spring they migrate to open deserts; boar have also colonized deserts in several areas they have been introduced to.<ref name=heptner1988 /><ref name="marsan55">{{Harvnb|Marsan|Mattioli|2013|pp=55–58}}</ref><ref>Long, J.

On the islands of [[Komodo (island)|Komodo]] and [[Rinca]], the boar mostly inhabits savanna or open monsoon forests, avoiding heavily forested areas unless pursued by humans.<ref name="auffenberg1981" /> Wild boar are known to be competent swimmers, capable of covering long distances. In 2013, one boar was reported to have completed the {{convert|7|mi|km|order=flip|0|adj=on}} swim from [[France]] to [[Alderney]] in the [[Channel Islands]].

Wild boar rest in shelters, which contain insulating material like [[spruce]] branches and dry [[hay]]. These resting places are occupied by whole families (though males lie separately) and are often located in the vicinity of streams, in swamp forests and in tall grass or shrub thickets. Boars never defecate in their shelters and will cover themselves with soil and pine needles when irritated by insects.<ref name=baskin2003 />

=== Diet ===
[[File:Scavenger feast - Yala December 2010 (2).jpg|thumb|Male Indian wild boar feeding on a [[chital]] (''Axis axis'') carcass]]
The wild boar is a highly versatile [[omnivore]], whose diversity in choice of food is comparable to that of [[human]]s.<ref name=marsan70/> Its foods can be divided into four categories:
* [[Rhizome]]s, [[root]]s, [[tuber]]s and [[bulb]]s, all of which it digs up throughout the year.<ref name=heptner1988 />
* [[Nut (fruit)|Nuts]], [[berries]] and [[seed]]s, which it digs up from under the snow when necessary and consumes when ripened.<ref name=heptner1988/>
* [[Leaves]], [[bark (botany)|bark]], twigs and [[Shoot (botany)|shoot]]s, along with [[garbage]].<ref name=heptner1988/>
* In warm periods, it eats [[earthworm]]s, [[insect]]s, [[mollusk]]s, [[fish]], [[rodent]]s, [[Insectivora|insectivores]], [[bird egg]]s, [[lizard]]s, [[snake]]s, [[frog]]s and [[carrion]].<ref name=heptner1988 />

A {{cvt|50|kg}} boar needs around 4,000–4,500 [[calorie]]s of food per day, though this required amount increases during winter and pregnancy,<ref name=marsan70 /> with the majority of its diet consisting of food items dug from the ground, like underground plant material and burrowing animals.<ref name=heptner1988 /> [[Acorn]]s and [[beech]]nuts are invariably its most important food items in [[Temperate climate|temperate zones]],<ref>{{Cite web |url=http://www.fao.org/docrep/005/y4351e/y4351e0c.htm |title=FAO Ch.8 |access-date=22 October 2018 |archive-date=22 October 2018 |archive-url=https://web.archive.org/web/20181022113158/http://www.fao.org/docrep/005/y4351e/y4351e0c.htm |url-status=live}}</ref> as they are rich in the [[carbohydrate]]s necessary for the buildup of fat reserves needed to survive lean periods.<ref name=marsan70/> In Western Europe, underground plant material favoured by boars includes [[Pteridium aquilinum|bracken]], [[Epilobium|willow herb]], bulbs, meadow herb roots and bulbs and the bulbs of cultivated crops. Such food is favoured in early spring and summer, but may also be eaten in autumn and winter during beechnut and acorn crop failures. Should regular wild foods become scarce, boars will eat tree bark and [[fungi]], as well as visit cultivated [[potato]] and [[artichoke]] fields.<ref name=heptner1988 /> Boar soil disturbance and foraging have been shown to [[Ecological facilitation|facilitate]] [[Invasive species|invasive]] plants.<ref>{{Cite journal|last1=Tierney|first1=T.

=== Predators ===
[[File:Tiger's killing wild boar.jpg|left|thumb|[[Tiger]]s killing a wild boar in [[Kanha Tiger Reserve]]]]
Piglets are vulnerable to attack from medium-sized felids like [[Eurasian lynx]] (''Lynx lynx''), [[jungle cat]]s (''Felis chaus''), and [[snow leopard]]s (''Panthera uncia''), as well as other carnivorans like [[brown bear]]s (''Ursus arctos'') and [[yellow-throated marten]]s (''Martes flavigula'').<ref name=heptner1988 />

The [[wolf]] (''Canis lupus'') is the main predator of wild boar throughout most of its range. A single wolf can kill around 50 to 80 boars of differing ages in one year.<ref name=heptner1988 /> In Italy<ref name="marsan96">{{Harvnb|Marsan|Mattioli|2013|pp=96–97}}</ref> and Belarus' [[Belovezhskaya Pushcha National Park]], boars are the wolf's primary prey, despite an abundance of alternative, less powerful ungulates.<ref name="marsan96" /> Wolves are particularly threatening during the winter, when deep snow impedes the boars' movements. In the Baltic regions, heavy snowfall can allow wolves to eliminate boars from an area almost completely. Wolves primarily target piglets and subadults and only rarely attack adult sows. Adult males are usually avoided entirely.<ref name=heptner1988 /> [[Dhole]]s (''Cuon alpinus'') may also prey on boars, to the point of keeping their numbers down in northwestern Bhutan, despite there being many more [[cattle]] in the area.<ref>{{cite journal | last1 = Thinley | first1 = P | last2 = Kamler | first2 = JF | last3 = Wang | first3 = SW | last4 = Lham | first4 = K | last5 = Stenkewitz | first5 = U |display-authors=etal | year = 2011 | title = Seasonal diet of dholes (''Cuon alpinus'') in northwestern Bhutan | journal = Mammalian Biology| volume = 76 | issue = 4| pages = 518–520 | doi = 10.1016/j.mambio.2011.02.003 | bibcode = 2011MamBi..76..518T }}</ref>

Boars of all ages were once the primary prey of the [[tiger]] (''Panthera tigris'') in Transcaucasia, Kazakhstan, Middle Asia and the Far East up until the late 19th century. In modern times, tiger numbers are too low to have a limiting effect on boar populations. A single tiger can systematically destroy an entire sounder by preying on its members one by one, before moving on to another sounder. Tigers have been noted to chase boars for longer distances than with other prey. In two rare cases, boars were reported to gore a small tiger and a tigress to death in self-defense.<ref name="soviettiger">{{cite book |author1=Heptner, V. G. |author2=Sludskij, A.

=== Reconstructed range ===
The species originally occurred in [[North Africa]] and much of [[Eurasia]]; from the [[British Isles]] to [[Korea]] and the [[Sunda Islands]]. The northern limit of its range extended from southern [[Scandinavia]] to southern [[Siberia]] and [[Japan]]. Within this range, it was only absent in extremely dry deserts and [[Alpine climate|alpine]] zones. It was once found in North Africa along the [[Nile]] valley up to [[Khartoum]] and north of the [[Sahara]]. The species occurs on a few [[Ionian Islands|Ionian]] and [[Aegean Islands]], sometimes swimming between islands.<ref name= masseti2012>Masseti, M. (2012), ''Atlas of terrestrial mammals of the Ionian and Aegean islands'', Walter de Gruyter, pp. 139–141, {{ISBN|3-11-025458-1}}</ref> The reconstructed northern boundary of the animal's Asian range ran from [[Lake Ladoga]] (at 60°N) through the area of [[Novgorod]] and [[Moscow]] into the southern [[Ural (region)|Urals]], where it reached 52°N. From there, the boundary passed [[Ishim, Tyumen Oblast|Ishim]] and farther east the [[Irtysh]] at 56°N. In the eastern [[Baraba steppe]] (near [[Novosibirsk]]) the boundary turned steep south, encircled the [[Altai Mountains]] and went again eastward including the [[Tannu-Ola Mountains]] and [[Lake Baikal]]. From here, the boundary went slightly north of the [[Amur River]] eastward to its lower reaches at the [[Sea of Okhotsk]]. On [[Sakhalin]], there are only [[fossil]] reports of wild boar. The southern boundaries in Europe and Asia were almost invariably identical to the seashores of these continents. It is absent in the dry regions of [[Mongolia]] from 44 to 46°N southward, in China westward of [[Sichuan]] and in India north of the [[Himalayas]]. It is absent in the higher elevations of the [[Pamir Mountains|Pamir]] and the [[Tian Shan]], though they do occur in the [[Tarim Basin]] and on the lower slopes of the Tian Shan.<ref name=heptner1988 />

=== Present range ===
In recent centuries, the range of wild boar has changed dramatically, largely due to hunting by humans and more recently because of captive wild boar escaping into the wild. Prior to the 20th century, boar populations had declined in numerous areas, with British populations probably becoming extinct during the 13th century.<ref name="britishwildboar.org.uk">{{cite web |url=http://www.britishwildboar.org.uk/britain.htm |title=Wild boar in Britain |publisher=Britishwildboar.org.uk |date=21 October 1998 |access-date=30 July 2013 |url-status=usurped |archive-date=24 July 2011 |archive-url=https://web.archive.org/web/20110724013218/http://www.britishwildboar.org.uk/britain.htm }}</ref> In the warm period after the ice age, wild boar lived in the southern parts of [[Sweden]] and [[Norway]] and north of Lake Ladoga in [[Karelia]].<ref>{{cite book|author= Nummi, Petri|title= Suomeen istutetut riistaeläimet|year= 1988|pages= 37–38|publisher= Helsingin yliopisto, Maatalous- ja Metsäeläintieteen Laitos|isbn = 951-45-4760-8}}</ref> It was previously thought that the species did not live in [[Finland]] during prehistory because no prehistoric wild boar bones had been found within the borders of the country.<ref>[http://notes.helsinki.fi/halvi/tiedotus/vanhatvaitokset.nsf/504ca249c786e20f85256284006da7ab/f174390c39f4c294c2256b13004dcc6f?OpenDocument Jääkauden jälkeläiset – Suomen nisäkkäiden varhainen historia] {{Webarchive|url=https://web.archive.org/web/20160304214152/http://notes.helsinki.fi/halvi/tiedotus/vanhatvaitokset.nsf/504ca249c786e20f85256284006da7ab/f174390c39f4c294c2256b13004dcc6f?OpenDocument |date=4 March 2016 }} (in Finnish)</ref><ref>{{cite book |author=Koivisto, M. |title= Jääkaudet|pages= 207–208|publisher= WSOY|year= 2004|isbn = 951-0-29101-3}}</ref> It was not until 2013, when a wild boar bone was found in [[Askola]], that the species was found to have lived in Finland more than 8,000 years ago.

A revival of boar populations began in the middle of the 20th century. By 1950, wild boar had once again reached their original northern boundary in many parts of their Asiatic range. By 1960, they reached [[Leningrad]] and Moscow and by 1975, they were to be found in [[Archangelsk]] and [[Astrakhan]]. In the 1970s they again occurred in Denmark and Sweden, where captive animals escaped and now survive in the wild. In England, wild boar populations re-established themselves in the 1990s, after escaping from specialist farms that had imported European stock.<ref name="britishwildboar.org.uk" />

=== Status in Great Britain ===
[[File:Wild Boar at Culzie - geograph.org.uk - 1017910.jpg|thumb|Mixed sounder of wild boar and domestic pigs at Culzie, [[Scotland]]]]
By the 11th century, wild boars were apparently already becoming rare in Britain. A 1087 forestry law enacted by [[William the Conqueror]] punished through blinding the unlawful killing of a boar. [[Charles I of England|Charles I]] attempted to reintroduce the species into the [[New Forest]], but this population was exterminated in the 17th century during the [[English Civil War]]. Between their medieval extinction and the 1980s, when wild boar farming began, only a handful of captive wild boar, imported from the continent, were present in Britain. Occasional escapes of wild boar from wildlife parks have occurred as early as the 1970s, but since the early 1990s significant populations have re-established themselves after escapes from farms, the number of which has increased as the demand for meat from the species has grown. A 1998 [[Ministry of Agriculture, Fisheries and Food (United Kingdom)|MAFF]] (now [[Department for Environment, Food and Rural Affairs|DEFRA]]) study on wild boar living wild in Britain confirmed the presence of two populations of wild boar living in Britain; one in [[Kent]]/[[East Sussex]] and another in [[Dorset]].<ref name="britishwildboar.org.uk" />

Another DEFRA report, in February 2008,<ref>[https://web.archive.org/web/20080504155956/http://www.defra.gov.uk/news/2008/080219b.htm Government supports local communities to manage wild boar]. Department for Environment, Food and Rural Affairs. 19 February 2008</ref> confirmed the existence of these two sites as 'established breeding areas' and identified a third in [[Gloucestershire]]/[[Herefordshire]]; in the [[Forest of Dean]]/[[Ross on Wye]] area. A 'new breeding population' was also identified in [[Devon]]. There is another significant population in [[Dumfries]] and [[Galloway]]. Populations estimates were as follows:
* The largest population, in Kent/East Sussex, was then estimated at 200 animals in the core distribution area.
* The smallest, in west Dorset, was estimated to be fewer than 50 animals.
* Since winter 2005–2006 significant escapes/releases have also resulted in animals colonizing areas around the fringes of [[Dartmoor]], in [[Devon]]. These are considered as an additional single 'new breeding population' and currently estimated to be up to 100 animals.

Population estimates for the Forest of Dean are disputed as, at the time that the DEFRA population estimate was 100, a photo of a boar sounder in the forest near Staunton with over 33 animals visible was published and at about the same time over 30 boar were seen in a field near the original escape location of Weston under Penyard many kilometres or miles away. In early 2010 the Forestry Commission embarked on a cull,<ref>{{cite news |url=http://news.bbc.co.uk/1/hi/england/gloucestershire/8439997.stm |title=Wild boar cull is given go ahead |date=2010 |publisher=BBC News |access-date=14 May 2011 |archive-date=28 February 2020 |archive-url=https://web.archive.org/web/20200228224122/http://news.bbc.co.uk/1/hi/england/gloucestershire/8439997.stm |url-status=live }}</ref> with the aim of reducing the boar population from an estimated 150 animals to 100.

=== Introduction to North America ===
[[File:Florida- 1745 Gators vs Pigs.JPG|thumb|"[[Feral pig|Razorback]]s" confronting an [[American alligator]] in [[Florida]]]]
Wild boars are an [[invasive species]] in the Americas, having been introduced by European explorers and settlers in the 16th century to serve as a source of food. Wild boars now cause problems including out-competing native species for food, destroying the nests of ground-nesting species, killing fawns and young domestic livestock, destroying agricultural crops, eating tree seeds and seedlings, destroying native vegetation and wetlands through wallowing, damaging water quality, coming into violent conflict with humans and pets and carrying pig and human diseases including [[brucellosis]], [[trichinosis]] and [[pseudorabies]]. In some jurisdictions, it is illegal to import, breed, release, possess, sell, distribute, trade, transport, hunt, or trap Eurasian boars. Hunting and trapping is done systematically, to increase the chance of eradication and to remove the incentive to illegally release boars, which have mostly been spread deliberately by sport hunters.<ref>{{cite web|url=http://www.dec.ny.gov/animals/70843.html|title=Eurasian Boar – NYS Dept. of Environmental Conservation|website=dec.ny.gov|access-date=22 April 2017|archive-date=23 April 2017|archive-url=https://web.archive.org/web/20170423063841/http://www.dec.ny.gov/animals/70843.html|url-status=live}}</ref>

==== History ====
While domestic pigs, both captive and feral (popularly termed "razorbacks"), have been in North America since the earliest days of [[European colonization of the Americas|European colonization]], pure wild boars were not introduced into the New World until the 19th century. The suids were released into the wild by wealthy landowners as big game animals. The initial introductions took place in fenced enclosures, though several escapes occurred, with the escapees sometimes intermixing with already established feral pig populations.

The first of these introductions occurred in [[New Hampshire]] in 1890. Thirteen wild boars from Germany were purchased by [[Austin Corbin]] from [[Carl Hagenbeck]] and released into a {{convert|9500|ha|acre|adj=on}} game preserve in [[Sullivan County, New Hampshire|Sullivan County]]. Several of these boars escaped, though they were quickly hunted down by locals. Two further introductions were made from the original stocking, with several escapes taking place due to breaches in the game preserve's fencing. These escapees have ranged widely, with some specimens having been observed crossing into [[Vermont]].<ref name="mayer2009">Mayer, J. J. et al. (2009), ''[http://www.wildpigconference.com/pdf/SRNL-Mayer-Biology%20Damage%20Control.pdf Wild Pigs: Biology, Damage, Control Techniques and Management] {{webarchive|url=https://web.archive.org/web/20141024035753/http://www.wildpigconference.com/pdf/SRNL-Mayer-Biology%20Damage%20Control.pdf |date=24 October 2014 }}'', Savannah River National Laboratory Aiken, South Carolina, SRNL-RP-2009-00869</ref>

In 1902, 15–20 wild boar from Germany were released into a {{convert|3200|ha|acre|adj=on}} estate in [[Hamilton County, New York|Hamilton County]], New York. Several specimens escaped six years later, dispersing into the [[William C. Whitney Wilderness Area]], with their descendants surviving for at least 20 years.<ref name="mayer2009" />

The most extensive boar introduction in the US took place in western [[North Carolina]] in 1912, when 13 boars of undetermined European origin were released into two fenced enclosures in a game preserve in [[Hooper Bald]], Graham County. Most of the specimens remained in the preserve for the next decade, until a large-scale hunt caused the remaining animals to break through their confines and escape. Some of the boars migrated to [[Tennessee]], where they intermixed with both free-ranging and feral pigs in the area. In 1924, a dozen Hooper Bald wild pigs were shipped to [[California]] and released in a property between [[Carmel River (California)|Carmel Valley]] and the [[Los Padres National Forest]]. These hybrid boar were later used as breeding stock on various private and public lands throughout the state, as well as in other states like [[Florida]], [[Georgia (U.S. state)|Georgia]], [[South Carolina]], [[West Virginia]] and [[Mississippi]].<ref name="mayer2009" />

Several wild boars from [[Leon Springs, Texas|Leon Springs]] and the [[San Antonio Zoo and Aquarium|San Antonio]], [[Saint Louis Zoo|Saint Louis]] and [[San Diego Zoo]]s were released in the Powder Horn Ranch in [[Calhoun County, Texas|Calhoun County]], Texas, in 1939. These specimens escaped and established themselves in surrounding ranchlands and coastal areas, with some crossing the [[Espiritu Santo Bay]] and colonizing [[Matagorda Island]]. Descendants of the Powder Horn Ranch boars were later released onto [[San José Island (Texas)|San José Island]] and the coast of [[Chalmette, Louisiana|Chalmette]], Louisiana.<ref name="mayer2009" />

Wild boar of unknown origin were stocked in a ranch in the [[Edwards Plateau]] in the 1940s, only to escape during a storm and hybridize with local feral pig populations, later spreading into neighboring counties.<ref name="mayer2009" />

Starting in the mid-1980s, several boars purchased from the San Diego Zoo and [[Tierpark Berlin]] were released into the United States. A decade later, more specimens from farms in [[Canada]] and Białowieża Forest were let loose. In recent years, wild pig populations have been reported in 44 states within the US, most of which are likely wild boar–feral hog hybrids. Pure wild boar populations may still be present, but are extremely localized.<ref name="mayer2009" />

====Effect on other habitats====

Wild boars negatively impact other habitats through the destruction of the environment, or homes of wildlife. When wild boars invade new areas, they adapt to the new area by trampling and rooting, as well as displacing many saplings/nutrients. This causes a decrease in growing of many plants and trees. Water is also affected negatively by wild boars. When wild boars are active in streams, or small pools of water, it causes increased turbidity (excessive silt and particle suspension).<ref>{{Cite web|last=State|first=Mississippi|date=11 November 2021|title=Environmental Damage|url=https://www.wildpiginfo.msstate.edu/damage/environment.php|url-status=live|website=Mississippi State University|access-date=13 November 2021|archive-date=5 November 2021|archive-url=https://web.archive.org/web/20211105083618/https://www.wildpiginfo.msstate.edu/damage/environment.php}}</ref> In some cases, the fecal coliform concentration increases to dangerous levels because of wild boars. Aquatic wildlife is affected, more prominently fish, and amphibians. Wild boars have caused a great decrease in over 300 animal or plant species, 250 being endangered or threatened.<ref>{{Cite news |date=May 2020 |title=FERAL SWINE: Impacts on Threatened and Endangered Species |work=United States Department of Agriculture |url=https://www.aphis.usda.gov/publications/wildlife_damage/fsc-feral-swine-impacts-tes.pdf |access-date=11 November 2021 |archive-date=11 November 2021 |archive-url=https://web.archive.org/web/20211111214707/https://www.aphis.usda.gov/publications/wildlife_damage/fsc-feral-swine-impacts-tes.pdf |url-status=live }}</ref>

The boars cause many habitats to become less diverse because of their feeding behaviors and predation. Wild boars will dig up eggs of species and eat them, as well as killing other wildlife for food.

[[File:BTB in boar.png|thumb|Lesions consistent with [[Mycobacterium bovis|bovine tuberculosis]] on the lower jaw and lung of a wild boar]]
Wild boars are known to host at least 20 different parasitic worm species, with maximum infections occurring in summer. Young animals are vulnerable to [[helminth]]s like ''[[Metastrongylus]]'', which are consumed by boars through earthworms and cause death by parasitising the lungs. Wild boar also carry parasites known to infect humans, including ''[[Gastrodiscoides]]'', ''[[Trichinella spiralis]]'', ''[[Taenia solium]]'', ''[[Balantidium coli]]'' and ''[[Toxoplasma gondii]]''.<ref name=toxo>{{cite journal | last1 = Jokelainen | first1 = P. | last2 = Velström | first2 = K. | last3 = Lassen | first3 = B. | year = 2015 | title = Seroprevalence of ''Toxoplasma gondii'' in free-ranging wild boars hunted for human consumption in Estonia | doi = 10.1186/s13028-015-0133-z | journal = Acta Vet Scand | volume = 57 | issue = 1 | pages = 42 | pmid = 26239110| pmc = 4524169 | doi-access = free }}</ref> Wild boar in southern regions are frequently infested with [[tick]]s (''[[Dermacentor]]'', ''[[Rhipicephalus]]'', and ''[[Hyalomma]]'') and [[Haematopinus suis|hog lice]].

The boar as a warrior also appears in [[Germanic peoples|Germanic cultures]], with its image having been frequently engraved on shields and swords. They also feature on [[Germanic boar helmets]], such as the [[Benty Grange helmet]], where it was believed to offer protection to the wearer and has been theorised to have been used in spiritual transformations into swine, similar to [[berserkers]]. The boar features heavily in religious practice in [[Germanic paganism]] where it is closely associated with [[Freyr]] and has also been suggested to have been a totemic animal to the Swedes, especially to the [[Yngling|Yngling royal dynasty]] who claimed descent from the god.<ref name="Kovářová">{{cite journal |last1=Kovářová |first1=L. |title=The Swine in Old Nordic Religion and Worldview |journal=Háskóla Íslands |date=2011 |s2cid=154250096}}</ref>

According to [[Tacitus]], the [[Baltic people|Baltic]] [[Aesti]] featured boars on their helmets and may have also worn boar masks. The boar and pig were held in particularly high esteem by the [[Celts]], who considered them to be their most important sacred animal. Some [[Celtic deities]] linked to boars include [[Moccus]] and [[Veteris]]. It has been suggested that some early myths surrounding the Welsh hero [[Culhwch]] involved the character being the son of a boar god.<ref name=mallory1997 /> Nevertheless, the importance of the boar as a culinary item among Celtic tribes may have been exaggerated in popular culture by the ''[[Asterix]]'' series, as wild boar bones are rare among Celtic archaeological sites and the few that do occur show no signs of butchery, having probably been used in sacrificial rituals.<ref name=green2002>{{cite book |last=Green |first=M. |date=2002 |title=Animals in Celtic Life and Myth |publisher=Routledge |page=46 |isbn=1-134-66531-8}}</ref>

The boar also appears in [[Vedic mythology]] and [[Hindu mythology]]. A story present in the [[Brahmanas]] has the god [[Indra]] slaying an avaricious boar, who has stolen the treasure of the [[Asura (Hinduism)|asuras]], then giving its carcass to the god [[Vishnu]], who offered it as a sacrifice to the gods. In the story's retelling in the [[Charaka Samhita]], the boar is described as a form of [[Prajapati]] and is credited with having raised the Earth from the primeval waters.

In [[Japanese culture]], the boar is widely seen as a fearsome and reckless animal, to the point that several words and expressions in [[Japanese language|Japanese]] referring to recklessness include references to boars. The boar is the last animal of the [[Chinese zodiac|Oriental zodiac]], with people born during the [[Pig (zodiac)|year of the Pig]] being said to embody the boar-like traits of determination and impetuosity. Among Japanese hunters, the boar's courage and defiance is a source of admiration and it is not uncommon for hunters and [[mountain people]] to name their sons after the animal ''inoshishi'' (猪). Boars are also seen as symbols of fertility and prosperity; in some regions, it is thought that boars are drawn to fields owned by families including pregnant women, and hunters with pregnant wives are thought to have greater chances of success when boar hunting. The animal's link to prosperity was illustrated by its inclusion on the [[¥]]10 note during the [[Meiji period]] and it was once believed that a man could become wealthy by keeping a clump of boar hair in his wallet.<ref name=knight2003>Knight, J.

The [[Ancient Rome|Romans]] inherited this tradition, with one of its first practitioners being [[Scipio Aemilianus]]. Boar hunting became particularly popular among the young nobility during the 3rd century BC as preparation for manhood and battle. A typical Roman boar hunting tactic involved surrounding a given area with large nets, then flushing the boar with dogs and immobilizing it with smaller nets. The animal would then be dispatched with a ''venabulum'', a short [[spear]] with a [[crossguard]] at the base of the blade. More than their Greek predecessors, the Romans extensively took inspiration from boar hunting in their art and sculpture. With the ascension of [[Constantine the Great]], boar hunting took on Christian allegorical themes, with the animal being portrayed as a "black beast" analogous to [[Saint George and the Dragon|the dragon]] of [[Saint George]].<ref name="scheggi9">{{Harvnb|Scheggi|1999|pp=9–58}}</ref>

Boar hunting continued after the [[fall of the Western Roman Empire]], though the Germanic tribes considered the [[red deer]] to be a more noble and worthy quarry. The post-Roman nobility hunted boar as their predecessors did, but primarily as training for battle rather than sport. It was not uncommon for medieval hunters to deliberately hunt boars during the breeding season when the animals were more aggressive. During the [[Renaissance]], when [[deforestation]] and the introduction of [[firearm]]s reduced boar numbers, boar hunting became the sole prerogative of the nobility, one of many charges brought up against the rich during the [[German Peasants' War]] and the [[French Revolution]].<ref name="scheggi9"/>

During the mid-20th century, 7,000–8,000 boars were caught in the Caucasus, 6,000–7,000 in Kazakhstan and about 5,000 in Central Asia during the [[Soviet]] period, primarily through the use of dogs and beats.<ref name=heptner1988 /> In Nepal, farmers and poachers eliminate boars by baiting balls of wheat flour containing explosives with kerosene oil, with the animals' chewing motions triggering the devices.<ref>Shreshta, Tej Kumar (1997).

Boars can be damaging to [[agriculture]] in situations where their natural habitat is sparse. Populations living on the outskirts of towns or farms can dig up [[potato]]es and damage [[melon]]s, [[watermelon]]s and [[maize]]. However, they generally only encroach upon farms when natural food is scarce. In the [[Białowieża Forest|Belovezh forest]] for example, 34–47% of the local boar population will enter fields in years of moderate availability of natural foods. While the role of boars in damaging crops is often exaggerated,<ref name=heptner1988 /> cases are known of boar depredations causing [[famine]]s, as was the case in [[Hachinohe, Aomori|Hachinohe]], Japan in 1749, where 3,000 people died of what became known as the "wild boar famine".

A 2023 study found that allowing wild pigs to forage on edible garbage in large regional landfills results in those animals getting physically large/heavier, having larger litters of piglets, and causing more wild pig-vehicle collisions in the vicinity of the landfill. The effects of letting these pigs scavenge in these landfills can present unique challenges to population management, control, public safety, and disease transmission. Wild pigs foraging on edible food waste in landfills has also been identified as a vector that facilitates the spread of African swine fever virus.<ref>{{cite journal |last1=Mayer |first1=John |last2=Edwards |first2=Thomas |last3=Garabedian |first3=James |last4=Kilgo |first4=John |title=Sanitary waste landfill effects on an invasive wild pig population |journal=Journal of Wildlife Management |date=2021 |volume=85 |issue=5 |pages=868–879 |doi=10.1002/jwmg.22042 |bibcode=2021JWMan..85..868M |osti=1782427 |s2cid=233601579 }}</ref>

=== Attacks on humans ===
Actual attacks on humans are rare, but can be serious, resulting in penetrating injuries to the lower part of the body. They generally occur during the boars' [[Rut (mammalian reproduction)|rutting]] season from November to January, in agricultural areas bordering forests or on paths leading through forests. The animal typically attacks by charging and pointing its tusks towards the intended victim, with most injuries occurring on the [[thigh]] region. Once the initial attack is over, the boar steps back, takes position and attacks again if the victim is still moving, only ending once the victim is completely incapacitated.<ref name=manipady2006>{{cite journal | last1 = Manipady | first1 = S. | display-authors = etal | year = 2006 | title = Death by attack from a wild boar | url = http://www.phossil.com/thom/4th%20July%20Hog/Wild%20Boar%20Attacks/Death%20By%20Wild%20Boar.pdf | journal = Journal of Clinical Forensic Medicine | volume = 13 | issue = 2 | pages = 89–91 | doi = 10.1016/j.jcfm.2005.08.007 | pmid = 16263321 | access-date = 9 October 2014 | archive-date = 18 October 2014 | archive-url = https://web.archive.org/web/20141018193808/http://www.phossil.com/thom/4th%20July%20Hog/Wild%20Boar%20Attacks/Death%20By%20Wild%20Boar.pdf | url-status = live }}</ref><ref name=gunduz2007>{{cite journal | last1 = Gunduz | first1 = A. | display-authors = etal | year = 2007 | title = Wild Boar Attacks | url = http://www.phossil.com/thom/4th%20July%20Hog/Wild%20Boar%20Attacks/Wild%20Boar%20Attack%20III.pdf | journal = Wilderness and Environmental Medicine | volume = 18 | issue = 2 | pages = 117–119 | doi = 10.1580/06-weme-cr-033r1.1 | pmid = 17590063 | s2cid = 1528398 | access-date = 20 August 2012 | archive-date = 9 August 2017 | archive-url = https://web.archive.org/web/20170809140100/http://phossil.com/thom/4th%20July%20Hog/Wild%20Boar%20Attacks/Wild%20Boar%20Attack%20III.pdf | url-status = dead }}</ref>

Boar attacks on humans have been documented throughout history. The Romans and Ancient Greeks wrote of these attacks ([[Odysseus]] was wounded by a boar and [[Adonis]] was killed by one). A 2012 study compiling recorded attacks from 1825 to 2012 found accounts of 665 human victims of both wild boars and feral pigs: the highest number of those attacks (24%) occurred in the United States, though the next-highest (19%), in India, was also the greatest percentage of attacks occurring in the animal's native range. Most of the attacks occurred in rural areas during the winter months in non-hunting contexts and were committed by solitary males.<ref name=mayer2013>Mayer, John J.

=== Management ===
Managing wild boar is a pressing task in both native and invasive contexts as they can be disruptive to other systems when not addressed. Wild boar find their success through adaptation of daily patterns to circumvent threats. They avoid human contact through nocturnal lifestyles, despite the fact that they are not evolutionarily predisposed, and alter their diets substantially based on what is available.<ref name=":02">{{Cite journal|last1=Johann|first1=Franz|last2=Handschuh|first2=Markus|last3=Linderoth|first3=Peter|last4=Dormann|first4=Carsten F.|last5=Arnold|first5=Janosch|date=2020-01-09|title=Adaptation of wild boar (Sus scrofa) activity in a human-dominated landscape|journal=BMC Ecology|volume=20|issue=1|pages=4|doi=10.1186/s12898-019-0271-7|issn=1472-6785|pmc=6953143|pmid=31918698|bibcode=2020BMCE...20....4J |doi-access=free }}</ref> These "adaptive generalists", can survive in a variety of landscapes, making the prediction of their movement patterns and any potential close contact areas crucial to limiting damage.<ref name=":2">{{Cite journal|last1=Clontz|first1=Lindsay M.|last2=Pepin|first2=Kim M.|last3=VerCauteren|first3=Kurt C.|last4=Beasley|first4=James C.|date=2021-03-25|title=Behavioral state resource selection in invasive wild pigs in the Southeastern United States|journal=Scientific Reports|language=en|volume=11|issue=1|pages=6924|doi=10.1038/s41598-021-86363-3|pmid=33767284 |pmc=7994638 |bibcode=2021NatSR..11.6924C |issn=2045-2322}}</ref> All of these qualities make them equally difficult to manage or limit.

Within Central Europe, the native habitat of the wild boar, there has been a push to re-evaluate interactions between wild boar and humans, with the priority of fostering positive engagement. Negative media and public perception of wild boar as "crop raiders" have made those living alongside them less willing to accept the economic damages of their behaviors, as wild boar are seen as pests. This media tone impacts management policy, with every 10 negative articles increasing wild boar policy activity by 6.7%.<ref name=":3">{{Cite journal|last1=Miller|first1=Ryan S.|last2=Opp|first2=Susan M.|last3=Webb|first3=Colleen T.|date=2018|title=Determinants of invasive species policy: Print media and agriculture determine U.S. invasive wild pig policy|journal=Ecosphere|language=en|volume=9|issue=8|pages=e02379|doi=10.1002/ecs2.2379|bibcode=2018Ecosp...9E2379M |s2cid=196685896 |doi-access=free}}</ref> Contrary to this portrayal, wild boar, when managed well within their natural environments, can be a crucial part of forest ecosystems.

Defining the limits of proper management is difficult, but the exclusion of wild boar from rare environments is generally agreed upon, as when not properly managed, they can damage agricultural ventures and harm vulnerable plant life.<ref name=":1">{{Cite journal|last1=Gray|first1=Steven M.|last2=Roloff|first2=Gary J.|last3=Kramer|first3=Daniel B.|last4=Etter|first4=Dwayne R.|last5=Vercauteren|first5=Kurt C.|last6=Montgomery|first6=Robert A.|date=2020|title=Effects of Wild Pig Disturbance on Forest Vegetation and Soils|url=https://onlinelibrary.wiley.com/doi/abs/10.1002/jwmg.21845|journal=The Journal of Wildlife Management|language=en|volume=84|issue=4|pages=739–748|doi=10.1002/jwmg.21845|bibcode=2020JWMan..84..739G |s2cid=214349584 |issn=1937-2817}}</ref> These damages are estimated at $800 million yearly in environmental and financial costs for the United States alone.<ref name=":1" /> The breadth of this damage is due to prior inattention and lack of management tactics for extended lengths of time.<ref name=":3" /> Managing wild boar is a complex task, as it involves coordinating a combination of crop harvest techniques, fencing, toxic bait, corrals, and hunting.

Wild boars are causing soil disturbance that, among other problems, globally results in annual carbon dioxide emissions equivalent to that of ~1.1 million passenger vehicles (4.9 Mt, 0.01% of all GHG emissions as of 2022), implying that as of 2021, hunted boar meat – unlike other meat products – has beneficial effects on the environment<ref>{{cite news |title=The climate impact of wild pigs greater than a million cars |url=https://phys.org/news/2021-07-climate-impact-wild-pigs-greater.html |access-date=14 August 2021 |work=phys.org |language=en |archive-date=3 August 2021 |archive-url=https://web.archive.org/web/20210803195708/https://phys.org/news/2021-07-climate-impact-wild-pigs-greater.html |url-status=live }}</ref><ref>{{cite journal |last1=O’Bryan |first1=Christopher J. |last2=Patton |first2=Nicholas R. |last3=Hone |first3=Jim |last4=Lewis |first4=Jesse S. |last5=Berdejo-Espinola |first5=Violeta |last6=Risch |first6=Derek R. |last7=Holden |first7=Matthew H. |last8=McDonald-Madden |first8=Eve |title=Unrecognized threat to global soil carbon by a widespread invasive species |journal=Global Change Biology |year=2021 |volume=28 |issue=3 |pages=877–882 |doi=10.1111/gcb.15769 |pmid=34288288 |s2cid=236157683 |language=en |issn=1365-2486}}</ref> even though the effect would diminish if boars are introduced for meat production, so consistently retaining small populations of boars may be preferable.
