Białowieża National Park

Listen first. Under the trees here, the air is cooler and damp, and it smells of moss, wet bark and slow decay. Somewhere above you, a woodpecker drums against dead wood. The ground is soft and springy underfoot. There is no single path of light through the canopy. Instead it falls in scattered patches, green and gold, across fallen trunks that nobody has cleared away. You have entered one of the last fragments of a forest that once covered much of lowland Europe.

This is Białowieża, and it lies on the far eastern edge of Poland. The forest does not stop at the national border. It continues into Belarus, where people know it as Belovezhskaya Pushcha. Together the two halves form one living system. Animals cross the line freely, and so do seeds, fungi and the slow movement of the trees themselves. The town of Hajnówka, a short drive away, has been a gateway to this forest for generations of foresters, workers and visitors.

Why does this place survive when almost every other old lowland forest in Europe is gone? The answer is a little ironic. For centuries, this was a royal hunting ground. Polish kings and the grand dukes of Lithuania guarded it for their own sport. Later, the Russian tsars did the same. Ordinary people faced strict limits on cutting trees and hunting game. Protection came from privilege, not from conservation. But the result was a forest left largely to itself.

Poland created a national park here in 1932, building on an earlier forest reserve. In 1979, UNESCO added the forest to its World Heritage List, and the listing was later extended to the Belarusian side. Today, only part of the wider forest sits inside the national park. The rest is managed woodland and nature reserves. This difference matters, as you will hear in a moment.

Look at the trees around you. Here is the first surprise for many visitors. A healthy old forest is not tidy. Dead trunks stand upright for years. Others lie on the ground and slowly turn to soil. In a commercial forest, this wood is removed. Here, it stays — and it is full of life. Beetles, fungi, mosses and nesting birds all depend on it. Scientists consider this dead wood one of the most valuable features of the whole forest.

The living trees are a mixed company. You will see oaks, hornbeams, lime trees, maples, ash and tall spruce. Some of the old oaks and spruces grow to remarkable heights, far taller than trees in most European woodland. Because nobody plants them in rows, they grow at every age side by side. A young sapling rises beside a giant, and both stand near a fallen trunk. This mix of ages is exactly what a natural forest looks like.

Now to the animal that made Białowieża famous: the European bison, called żubr in Polish. It is the heaviest land animal in Europe. By the early twentieth century, hunting and war had pushed it to the edge. The last wild bison in this forest died in 1919, killed by a poacher. For a short time, the species survived only in zoos and private parks across Europe.

Then came the second surprise. In 1929, a breeding centre began work here with just a handful of captive animals. Slowly, carefully, the herd grew. In the 1950s, bison were released back into the wild forest. Today, hundreds roam freely across the Polish and Belarusian sides. Almost every European bison alive today comes from a very small group of ancestors. That makes this forest the place where an entire species came back.

You may not meet a wild bison on the trail. They are shy, and they move through the forest at their own pace. Winter often gives the best chance, when they come into open meadows to feed. If you want a reliable view, the bison show reserve near Białowieża village keeps animals in large enclosures. There you can also see other native species, including elk, wild boar and the tarpan-like Polish horse.

The forest holds many more creatures. Wolves and lynx live here, though few visitors ever see them. Birdwatchers come for owls and for several kinds of woodpecker, some of them rare elsewhere in Europe. The forest floor carries thousands of species of fungi and insects. Many have been found only in very old forests like this one. Researchers still describe new species here. The place works as an open-air laboratory as much as a park.

The heart of the national park is the strict reserve. Here, nature is left almost entirely alone. You may enter it only with a licensed guide, on set routes. This rule protects the forest from too many footsteps. It also gives the walk a different feeling. You move slowly, in a small group, and you listen. Outside the strict reserve, marked trails and boardwalks let you explore on your own.

This forest has also known conflict. In recent years, large-scale logging in the managed parts of the forest caused protests across Poland. In 2018, the European Union's highest court ruled that the logging broke European law. More recently, Poland built a tall border barrier through the forest, and scientists worry about its effect on animals that cross between countries. The debate continues. Even a protected forest depends on human decisions.

The human story around the forest is part of the experience too. This corner of Poland, called Podlasie, has a strong Orthodox Christian tradition and a Belarusian minority. In Hajnówka and the nearby villages, you will see wooden houses with carved, painted window frames. Onion-domed churches stand among the fields. Local menus often include dishes made with forest mushrooms and berries. The forest shaped the people here, and the people shaped the forest.

Before you leave, stand still for one more minute. Look down at a fallen trunk covered in moss and small fungi. Look up at the light moving through leaves high above you. Notice how quiet it is — and how full that quiet is. Birdsong, insects, the creak of old wood. As you walk back toward the road, remember that this forest is still changing, slowly, as it has for thousands of years.
