Białowieża National Park: Europe's last lowland primeval forest

A century of leaving a forest alone

The park's story starts in 1921, when part of the Białowieża Forest was set aside as a forest district called simply „Reserve” and all management stopped. On 11 August 1932 it became Poland's first national park. After the Second World War, when the new border cut the forest in two, the park was re-established in 1947 within different boundaries.

It now covers about 105 square kilometres, with a buffer zone of some three thousand hectares more. Over half of that area is under strict protection: no tree is felled, no windthrow cleared, nothing gathered. That decision — not to improve anything — is what makes Białowieża what it is, and it is close to impossible to recreate elsewhere.

Calling the forest primeval does not mean nobody ever walked into it. It means it was never turned into a plantation. For centuries it was a royal and later a tsarist hunting ground, and that aristocratic interest is, paradoxically, what saved it. The result is a stand of a kind no other European lowland offers: trees of every age side by side, enormous quantities of dead wood, and gaps left by fallen giants where the next generation starts immediately.

What lives here

Most of the ground is held by oak-hornbeam forest, a mixed broadleaf woodland of hornbeam, lime, maple and oak; river valleys carry alder carr and floodplain forest, poorer sands carry pine and spruce. The oldest oaks are several centuries old, and the spruces reach heights unseen elsewhere in Poland simply because nobody cuts them at harvesting age.

The species counts are hard to hold in the head: more than twelve thousand animal species have been recorded, including 58 mammals and around a hundred and twenty birds, along with over seven hundred vascular plants and close to three hundred lichens. Fungi and insects tied to dead wood form a vast group of their own, and many of them would not survive in a tidied commercial forest.

Wolf and lynx are the large predators; elk, red deer, roe deer and wild boar the large herbivores. For birdwatchers the draw is above all the woodpeckers — white-backed and three-toed among them — plus owls, collared flycatchers and other hole-nesters that depend on old trees.

The bison, brought back from nothing

In 1914 more than seven hundred European bison still lived in the forest. War and poaching worked so fast that the last free-living animal here died in 1919, leaving a few dozen worldwide in zoos and private herds. For eight years there was not a single bison in Białowieża.

Recovery began in 1929, when a breeding enclosure was built and the first animals brought back from European collections. Only in 1952 were two bulls released into the forest again, with the same step taken on the Belarusian side a year later. Every free-ranging bison alive today descends from that handful of animals, which makes the species one of the best-documented conservation successes in Europe.

Around nine hundred bison now live across the whole forest, roughly half of them on the Polish side. Meeting a wild herd is a matter of luck and rarely happens; visitors who want a certainty go to the Bison Show Reserve on the road from Białowieża to Hajnówka, where tarpan-type horses, elk and wolves are also kept in large enclosures.

World Heritage status, and the arguments around it

The Polish park was inscribed on the World Heritage List in 1979. In 1992 the listing was extended across the border to Belavezhskaya Pushcha in Belarus, creating one of the world's few transboundary natural sites. The largest change came in 2014, when the property was renamed „Białowieża Forest” and enlarged to nearly a hundred and forty-two thousand hectares on both sides of the border.

It remains Poland's only natural World Heritage site; every other Polish entry is cultural. How the forest is managed is not settled, though. Logging in the commercially managed parts led to proceedings before the Court of Justice of the European Union, and since 2022 a steel barrier has run along the state border, cutting the forest and obstructing animal movement. Lynx and wolf, which need large connected territories, are affected most.

Visiting

• Strictly protected area — entry only with a licensed park guide, in small groups on a set route; this is as close to an untouched forest as it gets.
• Nature and Forest Museum — an exhibition about the forest with a viewing tower, a sensible first stop.
• Palace Park — a nineteenth-century landscaped park in the middle of the village, freely open, housing the park authority.
• Bison Show Reserve — enclosures on the Hajnówka road, the one place where seeing a bison is guaranteed.
• Getting there — train or coach to Hajnówka, then a bus to Białowieża; by car, a little over an hour from Białystok.
• Border zone — some areas near the frontier have their own rules and occasional access restrictions; check the park's website before travelling.
