The foreign animals of Peru are species originating from other countries that man has introduced to that nation. The impact on the local, regional or national ecology of these new species is variable.
Some species could contribute, among other things, to pest control, being considered highly beneficial as they represent a natural alternative to chemical pesticides. In other cases, such as the European hare, its population has grown disproportionately, affecting agricultural plantations in the region.
The introduction , by man, of species to a habitat other than the native can occur accidentally or intentionally.
Man could carry out this action deliberately, thinking or not of the benefits that these new breeds of animals possibly generate. The motivations for this could be economic, ecological and enjoyable, among others.
The accidental introduction is possibly related to human movements or migrations, where these animals are unintentionally taken to another country.
Examples of foreign animals from Peru
This perissodactyl mammal is native to North America and belongs to the equidae family. It is a herbivore that has been domesticated by man and introduced to almost every continent. The horse reached the American continent in 1493, during the second voyage of Christopher Columbus .
