Grows to More Than 100 Copies

The population of brown bears in the Pyrenees reaches record numbers: it grows to more than 100 individuals

The sustained increase of this emblematic species in Catalonia marks a milestone in environmental conservation

The brown bear population in the Pyrenees has experienced notable growth, now exceeding one hundred specimens, according to the most recent data provided by the Brown Bear Cross-Border Monitoring Group (GSTOP). This organization, which includes the collaboration of the Generalitat of Catalonia, as well as France, Aragon, Navarra and Andorra, has been fundamental in the monitoring of this emblematic mammal in the mountain range.

In 2025, a total of 107 bears were identified throughout the mountain range, a significant increase compared to the 96 specimens recorded in 2024. Within this figure, Catalonia stands out with the presence of 54 bears, representing approximately half of the total population of the Pyrenees. This phenomenon not only reflects a success in the reintroduction programs started three decades ago, but also positions Catalonia as a key point for the conservation of the brown bear in southern Europe.

Breaking down the data, of the 54 bears that live in the Catalan mountains, 30 are males and 23 females, while there is one specimen whose identification has not yet been confirmed. The monitoring area for these animals covers more than 2,500 square kilometers, where multiple cameras and tracking systems have been installed to monitor their footprints, excrement and other signs of their presence.

However, despite the good news of the increase in the overall bear population, the GSTOP has pointed out a worrying trend in relation to the number of cubs. In Catalonia, only 3 bear cubs have been recorded in 2025, a drastic decrease compared to the 12 recorded the previous year. In the entire Pyrenees, the number rises to 8 cubs, which raises questions about the health and future of the bear population.

This decline in reproduction can be explained by several factors. Brown bear reproduction is neither an annual nor uniform phenomenon; It depends on the age of the females, their physical condition and, above all, the availability of food. Not all females reproduce each year, as some may be raising previous litters or entering periods of reproductive rest. Additionally, 10 bears have been recorded dead or missing, meaning there are fewer adults available for breeding and there could be undocumented cub losses.

Despite these concerns, overall bear population numbers continue to rise. Going from 94 individuals in 2024 to 107 in 2025, this shows that, although the reproduction rate is irregular, the population is finding its way towards increasing stability. On the other hand, GSTOP estimates indicate that the brown bear's movement area is around 7,000 square kilometers, which represents a slight reduction of 100 kilometers compared to the previous year. This change could be interpreted as a sign of consolidation, where bears have occupied most of the optimal zones and require less space to expand.

In summary, the brown bear population in the Pyrenees is at a crucial moment in its history. While the increase in the total number of individuals is a positive sign, the decrease in the number of offspring and the challenges in reproduction highlight the complexity of the conservation of this species. As we move forward, it will be essential to continue monitoring their population and adapt conservation strategies to ensure their future in these mountains.
