High elevation ecosystems harbour a high biodiversity which could be particularly threatened by invasion of exotic species. For the moment, those ecosystems are not yet invaded, but propagule pressure increases with augmented accessibility of remote areas and increased temperature due to global change. High elevation ecosystems provide therefore in interesting laboratory to study a for the moment not yet invaded area to gain insights in some processes of invasion ecology which could permit a more targeted control of invasive plants species.The expected results may contribute to an optimised protection of the biodiversity in a habitat which is for the moment still hardly affected by invasion by exotic plants but threatened by global warming and land use changes.
