Status of the species in Latvia: A widely distributed and very common species throughout the entire territory of Latvia. According to the data of the State Forest Service for 2019, the population of wild boars in Latvia is approximately 20,000 individuals.

Where do they live? Mixed and deciduous tree forests are places with the highest chances of meeting a wild boar, as well as forest areas with pronounced undergrowth and a wet area nearby. Wild boars enjoy various agricultural crops, for instance, potatoes, corn and spring cereals.

How do they live? Wild boars are herd animals. Only older male boars beyond the mating period are solitary animals. During the mating period or wedding, male boars show signs of attention and share their genetic material with multiple ladies. In spring the small squeakers with longitudinal lines and rather well developed body are born. The juvenile boars are quick to learn how to find food and gradually become more and more independent and more similar to their adult relatives. The sows of wild boar closely watch over and protect their young - the young mothers may even attack people to protect their piglets.

What do they eat? Wild boars are pronounced omnivores – this means that they really eat almost everything! Starting from various roots, tubers and plants (including seeds and fruit) to worms, insect maggots, larvae, snails and other invertebrates and finishing with vertebrates, small mammals, reptiles, birds and eggs, dead and injured animals, as well as young animals.

Usually wild boars obtain their food from topsoil by digging it up with their strong snoots and tusks.
