The European otter, once on the brink of extinction in France due to hunting and habitat loss, has made a remarkable comeback in recent decades. This recovery is largely attributed to a 1972 government decree that granted the species full legal protection, without the need for artificial reintroduction efforts. Between 2009 and 2023, the area where otters live in France grew by 40%, as their populations gradually expanded along the Atlantic coast and in the Massif Central region. Historically, otters were hunted for their thick fur and were sometimes seen as competitors by fishermen. Additional threats came from industrial pollution, pesticide runoff, and the destruction of wetlands. By the 1960s and 1970s, otters had nearly vanished from much of France, surviving only in isolated pockets along the Atlantic and in remote parts of the Massif Central. The 1972 decree marked a turning point, halting hunting and allowing otters to naturally reclaim their former habitats. Their return began in the late 1990s and gained momentum in the following years. However, a large area stretching from the Grand Est region to northern France remains largely untouched by otters, and the reason for this gap in their expansion is still unclear. The return of otters has not been without challenges, particularly for the aquaculture industry, where fish farms sometimes lose stock to otter predation. To address this, a program called "Otter and Fish Farming" was launched as part of national conservation efforts, set to run through 2028. The initiative includes education and support for fish farmers, drawing on the experience of a salmon farmer in Corrèze who has successfully managed to live alongside otters. Although the European otter has made a strong recovery, its presence is still limited in parts of northern and eastern France. This story highlights how species can rebound when human pressures are reduced, but it also shows the importance of balancing conservation with local economic needs. The otter’s return is a testament to the power of environmental protection, while also reminding us that ongoing cooperation between conservationists and communities is essential.
