Recent research has revealed the significant contribution of 170 European bison reintroduced to Romania’s Țarcu Mountains to offsetting carbon dioxide (CO2) emissions.

Led by scientists at the Yale School of the and funded by the Global Rewilding Alliance, the study highlights the crucial role of these bison in mitigating the effects of the climate crisis.

The European bison, which disappeared from Romania more than 200 years ago, made a remarkable comeback in 2014 thanks to the efforts of Rewilding and WWF Romania. Since then, the population has flourished, with more than 170 free-ranging bison now living in the Țarcu Mountains, making them one of the largest populations in Europe.

The landscape has the potential to support 350 to 450 bison, indicating room for additional growth.

Using a new model developed by researchers, the study estimated the additional amount of atmospheric CO2 captured and stored in soils by bison interactions within ecosystems.

The results revealed that bison grazing in an area of ​​almost 50 km² of grassland in the Țarcu Mountains could potentially capture an additional 2 million tonnes of carbon per year. This significant impact highlights the crucial role of bison in restoring ecological balance and combating climate change.


Professor Oswald Schmitz of the Yale School of the Environment highlighted the different ways bison influence ecosystems, including grazing, nutrient recycling, seed dispersal and soil compaction. These activities help prevent the release of large amounts of carbon, making rewilded bison valuable allies in the fight against climate change.

The reintroduction of bison to Romania has not only benefited biodiversity conservation, but also boosted nature-based tourism and rewilding businesses. The study results highlight the importance of rewilding efforts, including the reintroduction of keystone species like bison, to combat both biodiversity loss and the climate crisis.

This groundbreaking research provides policymakers with valuable insights into the potential of nature-based solutions to stabilize the global climate.

By prioritizing nature protection and restoration, countries can harness the carbon-capturing capabilities of wildlife like the European bison to simultaneously achieve climate resilience and biodiversity conservation goals.
