Read the brief

European bison are the heaviest wild land animals in Europe. They were hunted to extinction in the wild by the early 20th century. Captive breeding brought them back. They now live in reintroduced populations across Europe — including the Białowieża Forest — but remain absent from most of their former range. They eat grasses, sedges and herbs. They jump higher and longer than American bison — an observed adaptation to mountainous terrain.

    What it is

    It is a distinct European species — one of only two bison left on Earth.

  2. 2:24
    How it disappeared — and came back

    It was hunted to extinction in the wild by the early 20th century — then rebuilt from captivity.

  3. 3:42
    Where it stands now

    Captive breeding returned it to the wild — but it remains absent from most of its former range.

  4. 5:09
    How far it fell

    It vanished from most of Europe and Asia by late antiquity — surviving only in fragments until the 20th century.

  5. 6:21
    What it holds onto

    It is still Europe’s heaviest wild land animal — a fact unchanged by its near-erasure.

  6. 7:37
    What it does differently

    Its jumping ability exceeds the American bison’s — a documented adaptation to rugged terrain.

The written brief1 min read

What the species is and where it came from

It is a European species of bison, one of only two extant bison species. Carl Linnaeus first described it scientifically in 1758.

How it works, in terms someone would actually use

It lives in lowlands and ancient woodlands like the Białowieża Forest. It eats grasses, sedges, and herbs. It jumps higher and longer than the American bison — an observed adaptation to mountainous terrain.

What it gets right

It gets right the physical scale of a European wild land animal — still the heaviest in Europe. It gets right behavioural plasticity: jumping ability exceeds that of its American counterpart.

What it does not

It does not occupy most of its historical range. It does not survive outside managed reintroduction sites without human support.

What it changed

It changed conservation practice: it proved wild megafauna can be restored from captive stock alone, after total extirpation from the wild.

Who it is for, and who it is not

It is for people who seek large, wild, native mammals in European forests and lowlands. It is not for those expecting unmanaged, self-sustaining populations across broad geography.

Is it worth your time

Yes — if you want to see a large wild mammal that has been reintroduced across Europe after near-total extinction, and whose behaviour is visibly shaped by terrain.

Mountain gorillaMountain gorilla (Gorilla beringei beringei) is a subspecies of eastern gorilla. It lives only in the Albertine Rift montane cloud forest — specifically in two isolated populations: the Virunga Mountains (Uganda, Rwanda, DRC) and Bwindi Impenetrable National Park (Uganda). As of 2019, 1,063 individuals remain. It is listed as endangered by the IUCN (2018). Its thick, long fur enables survival in cold, misty, high-elevation conditions. It is herbivorous: 85.8% of its diet is leaves, shoots, stems and pith from 142 plant species. Whole genome sequencing shows recent population decline caused extensive inbreeding.

OrangutanOrangutans are three critically endangered great ape species native to Indonesia and Malaysia, now found only in parts of Borneo and Sumatra. They are the most arboreal and solitary of the great apes. Dominant adult males develop flanges and make long calls. They are the only surviving members of the subfamily Ponginae, which diverged from other hominids 19.3–15.7 million years ago. Their diet centres on fruit but includes diverse plant and animal matter. Conservation threats include habitat destruction, poaching, and the illegal pet trade.

Siberian tigerThe Siberian tiger is Panthera tigris tigris—not a distinct species—but the most cold-adapted population, confined to Korean pine forests in the Sikhote-Alin mountains. Its numbers have risen steadily since 2005, but its mitochondrial DNA shows near-zero diversity: one haplotype dominates all wild individuals. Genetic work ties it directly to the extinct Caspian tiger, revealing an unexpected east-west-east dispersal route from eastern China through Central Asia and back into the Russian Far East. It survives where few large predators can—yet its genetic uniformity makes it vulnerable to disease and environmental change.

White rhinocerosWhite rhinoceros is a grazing specialist with a square lip, social habits, and extreme divergence between subspecies—southern (17,464 wild) and northern (two females, last male died 2018). Poaching and habitat loss drive its Near Threatened status. It runs up to 40 mph. It lives only in grassland and savanna.
