The new Madrileños, recovered and adopted by surprise, enrich the fauna of the region
The article discusses the return of various wildlife species to Madrid, including animals that were once native to the region but had disappeared due to human activity. These include species such as otters, which were last recorded in the area in the 1970s, and now appear to be making a comeback thanks to environmental improvements like water purification efforts and habitat restoration. The presence of these animals, such as the otter spotted near the Manzanares River, indicates a growing biodiversity in the city. Biologists are monitoring their populations, and there are plans for further studies to confirm their stable presence. The article highlights how changes in environmental policies have contributed to this resurgence.
In April 2025, wildlife officials in Madrid confirmed the unexpected return of several ancient species to the Manzanares River, marking a notable shift in the region’s ecological landscape. Among them were the Eurasian beaver, once thought extinct in the area, and other animals believed to have vanished due to human activity over centuries. These creatures, some of which date back to the Pleistocene era, are among the most endangered in Europe. Their reappearance has sparked renewed interest in conservation efforts and raised questions about how human intervention might have facilitated their return. The resurgence began with the sighting of a river otter near the Presa 6 dam, close to the Puente de Toledo bridge, in the early hours of April 19. This was the first documented appearance of the species in Madrid since the 1970s. The otters, which had previously been driven away by pollution, habitat loss, and urban expansion, are now being observed more frequently along the riverbanks. Biologists attribute this change to improved water quality and stricter environmental regulations. A monitoring system set up by the Madrid City Council has captured footage showing the otters communicating, suggesting they may form small groups rather than remaining solitary. The beaver population, meanwhile, has become one of the most surprising developments. In April 2025, researchers identified signs of beavers near Mingorrubio, including gnawed tree branches and small paths leading to water sources. These findings suggest the presence of a breeding pair or small family. Unlike the otters, which appear to have returned naturally, the beavers were introduced to Spain through illegal releases starting in 2003. Initially released into the Ebro River, they spread to other regions, including Andalusia, before reaching Madrid. The lack of natural predators in the area has allowed the beavers to thrive and establish new territories. Biologist Mario Mairal Pisa, who led the discovery, noted that the beavers' presence indicates a broader trend of reintroduction efforts. He explained that these animals were originally brought from German breeding farms and later released in Belgium through nature conservation groups. Over time, they adapted to their surroundings and expanded their range. The beavers in Madrid are now part of a growing network of populations across Spain, each contributing to the gradual restoration of native ecosystems. Other species, such as the European lynx and wolf, have also begun to reclaim parts of the Madrid region. These large carnivores, historically absent due to hunting and habitat fragmentation, are gradually returning as forest cover expands and prey populations recover. Conservationists believe that the increased presence of these predators could help regulate herbivore numbers, promoting a healthier balance within the ecosystem. Environmental policies have played a crucial role in enabling these changes. Stricter laws governing water treatment, waste management, and land use have reduced pollution levels and restored habitats. Additionally, initiatives aimed at reintroducing native fish and crustaceans have created more favorable conditions for aquatic life, indirectly supporting the survival of species like the otter and beaver. As the situation continues to evolve, experts predict that the presence of these ancient species will grow. However, challenges remain, including the need for ongoing protection against urban encroachment and climate-related disruptions. Scientists are currently preparing a detailed study on the otter population in the Manzanares, hoping to confirm whether the sightings represent a stable, long-term presence or merely temporary occurrences. For now, the return of these remarkable animals stands as a testament to the potential for ecological recovery when conservation measures are effectively implemented.
