European Bison Reintroduction Project in Switzerland Faces Scrutiny

A unique project in Welschenrohr, Solothurn, aims to reintroduce the European bison ( *bison bonasus*) into the Swiss landscape, sparking both excitement and concern among scientists, farmers, and local communities.

Project Background and Current Status
For three years, a herd of European bison has been gradually reintroduced to a designated area in Welschenrohr, canton of Solothurn, nestled between the folds of the Jura Mountains. The herd has grown from an initial five individuals to eleven as of December 2025. The reintroduction has followed a phased approach, starting with a 5-hectare fenced park, expanding to 50 hectares, and most recently reaching 100 hectares (approximately one square kilometer).
The project aims to assess the feasibility of restoring a keystone species to the Swiss ecosystem and its potential impact on biodiversity and landscape management. The European bison, once nearly extinct, has been successfully reintroduced in several other european countries, including Poland, Belarus, and Romania. Rewilding Europe provides extensive details on bison reintroduction efforts across the continent.
Concerns and Potential Challenges
Despite the project’s progress, concerns remain regarding the potential for bison to cause damage to agricultural land. François Monin, director of Agri Jura, expressed apprehension about the bison venturing beyond the designated forest area and impacting crops. He noted that, like other wild species, bison might potentially be drawn to readily available food sources, such as grasslands and cultivated fields.
“As we sometimes see with other wild species, I am not sure that these bison will stay in the middle of the forest and not cause damage to crops if thay have grass and a fresh pantry available,” Monin pointed out.
Mitigation strategies, such as electric fencing and collaborative land management practices, are being considered to address these concerns. The long-term success of the project hinges on finding a balance between bison conservation and the interests of local farmers.
Next Steps and Future Plans
The next critical stage of the project is scheduled for March 2027. at that time, the canton of Solothurn will review a request to grant the bison semi-freedom over a 10 square kilometer area. This expansion would considerably increase the bison’s range and allow for a more natural grazing pattern. the decision will be based on an assessment of the project’s impact to date, including ecological monitoring data and feedback from stakeholders.
