This week, we’re speaking with Jens-Christian Svenning, one of Denmark’s leading researchers in biodiversity and wild nature. We talk about which animals would have lived in Europe if it weren’t for human interference, the role these animals play in our ecosystems, and what it would take to bring large animals back into the European temperate fauna.

In this special episode, we’re joined by Professor Jens-Christian Svenning from Aarhus University. He is a globally leading researcher in biology – particularly at the intersection of biodiversity, ecosystems, climate, and human–nature interactions from the past to the present. We discuss which large animals have gone extinct in recent times, what role they play in ecosystems, and what Europe might look like if humans were no longer around. These are some of the questions we explore. Disclaimer: This episode is in Danish.

An international research team has compiled more than 100 pollen analyses from the last interglacial period in Europe, creating a comprehensive picture of landscapes across different biogeographic regions. Professor Jens-Christian Svenning has supervised the study’s lead author, Elena Pearce, and we’ve invited him into the studio to talk about the findings. After gaining new insights, Rasmus and Andrew head to Mols Bjerge to compare the situation during the last interglacial period with the vegetation at the Mols Laboratory, where the area has been left to wild animal grazing for seven years. We also make time for today’s audio letter from Before Dad Was a Kid, submitted by Kasper Møller. Disclaimer: This episode is in Danish.

Nature is both a miracle and a battleground. In Vildspor, host and biodiversity researcher at Aarhus University, Rasmus Ejrnæs, sheds light on both. We follow him as he searches for vulnerable species and powerful emotions. Every week on Radio4, Rasmus offers new insights—both out in nature and in the studio—in conversations with researchers, politicians, and artists. Disclaimer: This program is in Danish.

Invasive species and extreme temperatures are actively reshaping ecosystems across the globe. But are these new ecosystems always worse than the ones we’re used to? A new Danish Center of Excellence is focusing on how we can create the best conditions for biodiversity—and for ourselves—when climate conditions exceed all known scales. Perhaps we need to get used to the idea that there are limits to what we can control? Guest: Jens-Christian Svenning, Professor of Biodiversity at Aarhus University and Director of the Center of Excellence ECONOVO (Center for Ecological Dynamics in a Novel Biosphere).

Both politicians and experts acknowledge that Denmark is facing an environmental and biodiversity crisis. Yet we still struggle to let go of habits we know are harmful to nature—such as cutting down old-growth forests and replacing them with new ones. Disclaimer: This content is in Danish.
