Wild boars have caused a great decrease in over 300 animal or plant species, 250 being endangered or threatened. [114] 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.
Elk, a large deer about 2 metres (6 ft 7 in) in height up to the shoulder, are common in this habitat. [6] Steppe animals include wild boar as well as 30 other mammal species. A small antelope species known a saiga antelope is also present but is under threat due to hunting. [6]
Buzuluksky Bor National Park (Russian: Бузулукский бор) encompasses the Buzuluk Pine Forest, which is the largest grove of isolated high pine trees in the world. [1] It is surrounded by steppes on the East European Plain east of the Volga River and west of the foothills running up to the southern Urals .
The Transbaikal terrestrial ecoregion covers the "Lake Baikal" Freshwater Ecoregion (WWF ID:606). This freshwater ecoregion supports a "large lakes" habitat for aquatic life, the primary focus of scientific study being on Lake Baikal itself and fish that spawn in the rivers that feed into it (such as the Barguzin River in the Transbaikal).

This vast ecoregion is located in the heart of Siberia, stretching over 20° of latitude and 50° of longitude [1] (52° to 72° N, and 80° to 130° E). The climate in the East Siberian taiga is subarctic (the trees growing there are coniferous and deciduous) and displays high continentality, with extremes ranging from 40 °C (104 °F) to −65 °C (−85 °F) and possibly lower.
The wild boar (Sus scrofa) can take advantage of any forage resources. Therefore, they can live in virtually any productive habitat that can provide enough water to sustain large mammals such as pigs. Pigs are famously fecund; when well-fed, a sow can birth twelve or more piglets in her annual litter.
The Sarala sector is more southern in character, with hares, wild boar, and roe deer. Beaver were reintroduced in 1996. Scientists on the reserve have recorded 50 species of mammals in the borders. Birds include forest birds and waterfowl, reflecting the variety of habitat in the area.
As the park is on the southern edge of the taiga, there are some large mammals such as elk, wild boar, and recently brown bear along the forest edges. Beavers are growing rapidly in number, along with muskrat, in the lakes and canals. In spring, migratory birds arrive in large numbers, particularly geese and ducks, with wading birds in the marshes.
