About Your Guide

A biologist living in Europe's last primeval forest

I'm Tom, a PhD ecologist based in the Białowieża Forest in eastern Poland. I moved here to study how wolves shape ecosystems — and never left. My current research explores how wolves and humans influence beaver impacts on trees.

Half Polish, half British, I grew up near Snowdonia in Wales — a landscape denuded of trees where you'd struggle to see anything wilder than a squirrel. In Białowieża, wolves, bison and moose canter through gardens. This wildlife was once common across all of Europe. As scientists who study this forest, we aim to share its secrets while exploring woods where few people ever go.
