Seminar participants on guided old-growth forest walk with Tom Diserens in Białowieża

I’m Tom, a biologist based in the Białowieża Forest in eastern Poland. I hold a PhD from Warsaw University, where my research focused on how wolves shape ecosystems. My current work explores how interactions between people and wolves influence the impacts of beavers on trees.

Poland has an exceptionally rich natural heritage. Much of the wildlife and ecological processes still present here have been lost over time in western Europe. Through my scientific work, I aim to contribute, however modestly, to  revealing some of these ecological secrets.

Few English-language sources present Polish wildlife to a wider audience. This website documents stories and observations from my work with wolves and other wildlife in Poland. I hope it proves useful, and that in a small way it helps keep attention on the value of Europe’s remaining wild places.
