The Reserve Nobody Planned

A wolf steps out onto asphalt that pine roots have split open. No cars. No voices. No dogs barking. This is northern Ukraine, inside a circle thirty kilometres wide around the Chernobyl power plant. And officially, it's a nature reserve. The Chernobyl Radiation and Ecological Biosphere Reserve was created on the twenty-sixth of April, two thousand sixteen, exactly thirty years after the accident. Almost two hundred twenty-seven thousand hectares, under protection.

Your first guess is probably that radiation somehow fed the place. Giants, wild abundance, life gone lush. But then why did the pines right next to the plant die within weeks?

They turned rust-red in a matter of days, then dried out. That's why it's called the Red Forest: about four square kilometres of dead pine woodland that took the hardest blow. Cleanup crews cut the trees down with bulldozers and buried them in trenches, two or three metres deep. Today that ground is counted among the dirtiest open places on the planet.

And now it gets strange. Two biologists, Timothy Mousseau and Anders Møller, scattered small mesh bags of clean leaves around the zone. Oak, maple, birch, pine needles. They came back nine months later and weighed what was left. Where the background radiation was higher, the leaves had lost about forty percent less weight. Nothing was there to break them down. Microbes, fungi and soil creatures were working more slowly. The study came out in a peer-reviewed ecology journal in two thousand fourteen, and people still argue about it.

Fungi, though, seem to like it here. Inside the ruined reactor building and in the cooling water, researchers found black moulds packed with melanin. One of them is called Cladosporium sphaerospermum. In experiments, its threads grow toward a radiation source. That's called radiotropism. Then comes a beautiful hypothesis from Ekaterina Dadachova and Arturo Casadevall: melanin works like chlorophyll, except it catches ionizing radiation instead of light. The fungus, in effect, eats radiation.

Nobody has managed to prove it. That the fungus grows better, you can see. How it does that, nobody has shown. On the International Space Station it was grown in an experiment, and it gained one point two times more than the control on Earth. Maybe it isn't feeding at all. Maybe it's shielding. Melanin absorbs energy and catches aggressive molecules inside the cell.

That same thought ties into the zone's most elegant find. The tree frogs here are dark. Almost black. Two Spanish researchers, Pablo Burraco and Germán Orizaola, examined more than two hundred males in twelve breeding ponds. They saw a pattern: the heavier the contamination in nineteen eighty-six, the darker the frogs are now. Over four decades, selection pushed forward the ones with more melanin.

Now, the catfish. The legend of monsters in the cooling pond is still alive, and the truth is dull. They're ordinary European catfish. The biggest one measured was about one and a half metres. For decades, plant workers fed them on the way back from the canteen, and nobody fished them. "A very rare mutation gives large size," Mousseau says. "Usually it's the opposite. They grow worse, feed worse, live shorter." After two thousand eighteen almost no fish were left in that pond. The pumping stopped, and the water is getting shallow.

The large animals, though, came back on their own. A study led by Tatyana Deryabina, published in a major biology journal in two thousand fifteen, found as many elk, roe deer, red deer and wild boar here as in clean reserves nearby. And seven times more wolves. Przewalski's horses were brought in during nineteen ninety-eight. Thirty-one animals, from Askania-Nova and a local zoo. The species had been declared extinct in the wild in nineteen sixty-nine. It took hold here. How many there are now depends on who's counting, and there's no exact number.

People argue about the rest, too. Jim Smith, from Portsmouth, is convinced that for wildlife, humans turned out to be more dangerous than radiation. Mousseau answers that birds here lay fewer eggs and get more cataracts. Both sides are looking at the very same land.

And that may be the honest ending. The zone isn't paradise, and it isn't a graveyard. It just shows what happens when you take people out of the picture.
