The United Nations Convention on the Conservation of Migratory Species has added the giant river otter to its list of species requiring urgent conservation action, citing sharp population declines and increasing environmental threats.
The decision was made in March 2026 during a meeting in Campo Grande, with the species now included under both Appendix I and II of the treaty, signaling the need for immediate and coordinated international protection efforts.
Native to tropical river systems across South America, the giant otter has suffered a population decline of about 50% over the past 25 years.
Once widespread east of the Andes, it is now extinct in some countries and critically endangered or vulnerable in others, according to conservation assessments by the International Union for Conservation of Nature.
Experts warn the decline is likely to continue due to habitat destruction, pollution, and climate change. Rivers are increasingly affected by damming, mining contamination, and agricultural expansion, while extreme droughts and wildfires further threaten survival.
Although illegal hunting for fur historically devastated populations, current threats are driven more by human-wildlife conflict and environmental degradation.
Competition with local fishing communities and negative perceptions of the species also complicate conservation efforts.
The giant otter, the largest of the world’s otter species, plays a key role as an apex predator and indicator of freshwater ecosystem health. Its presence signals healthy river systems, making its decline a broader environmental concern.
Because the species inhabits transboundary river systems such as those in the Amazon and Pantanal, conservationists emphasize the need for cross-border cooperation.
Maintaining river connectivity is critical, as habitat fragmentation poses a major risk to its survival.
The proposal to list the species was submitted by France and supported by several countries and the European Union. It was adopted without opposition alongside protections for dozens of other migratory species.
Under the CMS framework, the next step involves developing a coordinated international action plan, expected to be განხidered at a future summit scheduled in Germany in 2029.
Conservation groups say the listing sends a strong signal that urgent global action is needed to protect the species and the freshwater ecosystems it depends on.
