Not far from Brno, in the Czech Republic, an inspiring team of experts from various countries came together for a two-day workshop combining theory and practice on soil sampling. The workshop provided an immersive, hands-on experience focused on one of the most vital, complex, and still largely unexplored components of terrestrial ecosystems: the soil.

Organized by the WILDCARD project and involving both project researchers and external specialists, the soil sampling workshop aimed to align diverse research objectives under a shared mission: highlighting the critical role of soil in the context of rewilding. Over the two days, participants worked in two contrasting forest environments: one with soft, loamy soil that made the sampling procedure easy, and another with hard, rocky ground that challenged their adaptability and resilience. Thanks to the strong commitment of the group, once the technical training and minor hurdles were behind everyone, we group fully immersed ourselves in the environment. The workshop fostered a deep connection, not just among the participants, but also with nature and the often-overlooked world beneath our feet.

For many of us, soil might seem like little more than the “dirt stuff” we live on. But for Sara Cazzaniga from ETH Zurich, it’s a constantly shifting landscape of hidden stories. “Working with forest soil is particularly fascinating because of how much it varies”, she said. “Not only between sites, but even across different spots within the same forest.”

Sara came to Brno hoping the workshop would demystify the dense and challenging soil sampling protocol – and right from the start, she found a collaborative and supportive team. “As soon as we arrived at the first demonstration site, the outdoor setting felt just right,” she said. “Thanks to the shared insights and helpful observations, what initially felt difficult started to make sense. The hands-on practice really helped us become more comfortable and confident with applying the protocol.”

The group was a vibrant mix of backgrounds and expertise – from seasoned soil scientists to enthusiastic newcomers. That diversity quickly became a strength: beginners brought fresh questions, while more experienced participants shared field-tested tips. Everyone contributed with the shared goal of making the soil sampling protocol work – not just for science, but for nature, too.

“We had such a great mix of perspectives,” Sara added. “It made the tools and resources – like the app, FAQs, and videos – feel much more accessible and practical.”

Also, Yannick de Win from the Research Institute for Nature and Forest (EV-INBO) echoed that enthusiasm, “People often think of forests as trees, birds and mammals, but so many fundamental processes continuously happen belowground. That’s where trees and roots develop and where carbon is stored, thanks to the great diversity of organisms that live there.”

As part of the WILDCARD project, the teams at EV-INBO and Silva Tarouca Research Institute (VUK) will analyze both soil and forest floor layers to understand soil carbon dynamics, while Sara will extract environmental DNA from soil samples to investigate microbial community composition across different forest successional stages throughout Europe. Their combined efforts aim to reveal how soil carbon and biodiversity have shifted over time – specifically in areas where agricultural land and pastures were abandoned more than 70 years ago or forest management had been stopped.

The ultimate goal is to provide deeper insight into the potential for forest restoration and to inform strategies for climate change mitigation in the near future.

What began with this workshop is hoped to grow into a powerful reminder: that soil holds essential clues to the health of our planet and our future. In Brno, the WILDCARD team not only collected soil samples – they also planted seeds of knowledge, collaboration, and curiosity, laying the groundwork for more sustainable land management across Europe.
