I read the latest story on our web which explained that France has many species on the Red List of Threatened Species. (http://iucn.org/about/union/secretariat/offices/europe/?10218/IUCN-Red-List-of-Threatened-Species-France-ranks-fifth-worldwide). This is due to the fact that France still has overseas territories, like Nouvelle Calédonie or Guyane which are rich in biodiversity. The same applies to other European countries with overseas territories: the highest biodiversity in the Netherlands is in the reefs around the Caribbean islands that still fly the Dutch flag.
This amazing richness of species, coupled with the risk associate with climate change makes these overseas territories important and vulnerable corners of Europe. It is the main reason why IUCN is involved in a programme to support nature protection and help to develop climate change adaptation action in these far-flung places.
We have a dedicated website to describe the achievements of the programme, which you should have a look at: http://iucn.org/about/union/secretariat/offices/europe/activities/overseas/. If only to browse the photo gallery!
