ABSTRACT
Non-native species cause changes in the ecosystems to which they are introduced. These changes, or some of them, are usually termed impacts as they have both the direct and indirect impacts and they can be manifold and potentially damaging to ecosystems and biodiversity. The direct impact is more of aggressive competition for resources and allelopathic property and the indirect impact is changing the interests of society and making them to neglect the indigenous species on the management aspect, however, the indirect impact seems less recognized by ecologists, environmentalists, and other concerning bodies on the area. Therefore, assessing the impacts of alien species on ecology and/or indigenous species is not as straightforward as considering their economic impacts.
Key words: Eucalyptus, Indigenous species, Invasion, Non-native species
