Researchers are using camera traps and sampling points to track the Mustela putorius across the Cerdanya and Alt Urgell regions. This follows the 2024 discovery of an individual in Cerdanya, which prompted a formal monitoring program starting in 2025.

The project also monitors the threat of the invasive American mink. The European polecat is currently listed as an endangered species in Catalonia, with an estimated population of only 100 to 200 individuals remaining in the wild due to habitat loss and competition with invasive species.
