The EU-PoTaRCh (COST Action – CA22155) Training School brought us closer to the fascinating history and traditions of resin and charcoal production in Lower Austria. Over three days, participants experienced first-hand the cultural and environmental heritage of these practices, guided by local experts and families who have preserved the knowledge across generations.
Day 1 – Resin Harvesting Traditions
We began by learning about the history of resin production in Lower Austria. Until the 1960s, resin harvesting was an important source of income for many families, employing around 7,000 people. A professional resin harvester and his family would typically process between 3,000–5,000 trees per year.
The work was demanding and followed a strict process: after fore-hoeing in the spring, trees were maintained weekly with a planing tool to keep the resin flowing. The resin was collected in pitch cups, yielding on average 3 kg per tree per year. Black pine (Pinus nigra) was the main species used, with trees exploited for at least 40 years—sometimes even up to 70 years, with harvesting carried out on multiple sides of the trunk.
Despite heavy rain, participants were able to watch Bernhard demonstrate traditional harvesting techniques. Afterwards, the Rendl family, the last resin-harvesting family in Austria, welcomed us and shared their modern adaptations of traditional resin-based products.
Day 2 – Museums and Knowledge Exchange
The second day focused on resin in history and culture. We visited the Resin Museum in Hernstein and followed the educational trail, which explained the techniques and importance of resin extraction. In the afternoon, participants exchanged insights on the history and current practices of resin production across different European countries.
The day concluded with a visit to the Waldbauernmuseum in Gutenstein, where we gained a broader understanding of rural forestry traditions.
Day 3 – Charcoal Production
The final day was dedicated to charcoal. We visited two forest-farming families who continue to produce high-quality charcoal using traditional methods, combining their forestry work with this demanding craft.
Participants were able to compare two different techniques of charcoal production—the rectangular kiln and the round pile—discussing the challenges, advantages, and sustainability aspects of each. Gertrud and Peter Wieser presented their long kiln method and a unique charcoal collection, while Theresia Hochecker explained the round pile technique with great expertise.
Both families showed deep passion and pride in their work, highlighting how tradition and sustainability are intertwined in their daily practices.
