Origin and destination of selected invasive/alien species
Philippe Rekacewicz, UNEP/GRID-Arendal
Invasive and alien species that are brought into a new environment, either on purpose or by accident, can quickly exploit ecological niches that are not fully covered by indigenous (local) species. They will then quickly spread and outcompete the local wildlife.
