European bison

About

The European bison is the largest land mammal in Europe. At the beginning of the 20th century, it became extinct in the wild, and all modern European bison descend from a small number of animals that survived in zoos and animal parks. They were reintroduced to the Carpathians through breeding and release into the forests, and today, free herds exist in Ukraine, Poland, Slovakia, and Romania.

In Ukraine, the largest Carpathian group lives in the Skole Beskids National Nature Park in Lviv Oblast: in 2024, camera traps recorded about 50 bison there. In winter, the park supplements the herd with beets, corn, and grain. In the Polish Bieszczady, bison were reintroduced in 1963, and now it is one of the largest free herds in the country: according to the spring count in 2026, several hundred animals live there. In Slovakia, bison live freely in the Poloniny National Park, and in Romania — in the Călărași Mountains, in the Vânători-Neamț Natural Park, and on the Făgăraș Mountains.

An adult male has a massive hump on its shoulders, a short beard, and small curved horns; females are noticeably smaller. Bison graze in small herds led by experienced females, while older males often keep separate. They feed on grass, leaves, shoots, and bark, and in winter — on branches and supplementary feed. In summer, herds move to forest clearings and meadows, and in bad weather, they take shelter in the forest.

The return of bison is important not only for the species itself. By grazing and browsing bushes, they keep clearings open, where more grasses and flowers grow, and more insects and birds live. Therefore, the bison is called the "engineer" of forest landscapes, and its return is one of the most successful conservation stories in Europe.

The chances of seeing bison in the wild are low: herds roam large forest areas, and the exact places where they graze are not disclosed by the parks to avoid disturbing the animals. It is best to arrange a tour with the national park administration or to see bison in demonstration enclosures. The bison is listed in the Red Book of Ukraine with the status of "extinct in the wild": formally, free herds are considered restored from captivity. Hunting bison is prohibited. In 2020, the IUCN changed the species status from "vulnerable" to "near threatened" (NT) due to population recovery, particularly in Romania.

Where in the Carpathians

The map shows where naturalists recorded the species (GBIF, CC0 and CC BY records), not every place it lives. The Ukrainian Carpathians are less studied, so a blank area does not mean the species is absent. For rare and vulnerable species the map is deliberately coarse (hexagons of ~250 km² or more) so that it never points to dens, nests or growing sites.

From naturalists’ observations in the Carpathians (iNaturalist, research grade): the darker the cell, the more often the species is seen that month.
