Białowieża, Poland

I grew up near Snowdonia in Wales — a landscape I love but one that is, by any honest measure, an ecological ghost town. Coming to Białowieża felt like stepping into what Europe was supposed to look like.

I'm a biologist living in Białowieża Forest in eastern Poland. I have a PhD from Warsaw University on how wolves shape ecosystems.

Poland has a rich natural heritage. Here you can find the kind of nature that has been wiped out over time in western Europe. Through my scientific work I aim to contribute a little towards unlocking its ecological secrets.

I'm based at the Mammal Research Institute PAS in Białowieża, where I'm currently leading an NCN-funded project investigating how wolves and humans together shape beaver behaviour and ecosystem impacts — a project running across field sites in Poland and the Netherlands.

Few English sources show Polish wildlife to the world. Hence my website documents stories I encounter about the wolves and wildlife inhabiting Poland. I hope you'll find it useful. Perhaps in this small way I can help society keep a hold of its few remaining wild places for future generations.

If you'd like to see this forest through the eyes of someone who researches it, I run small expert-led tours several times a year.
