These are species that do not belong to the local fauna. They are often invasive and introduced by humans for hunting, fishing, food, or companionship. They consist of animals from other countries, often from other continents, and create serious imbalances in the ecosystem since there are few predators or diseases that could keep them under control. For many of these species, containment or eradication projects are underway or being studied. It is strictly forbidden to introduce any animal or plant species into natural environments, and even more so in protected areas!
