Invasive species are one of the greatest risks to biodiversity. They
are right up there with habitat destruction in terms of threat. Islands
like Seychelles can only remain a refuge for native and endemic species
while invasive aliens are kept at bay. Nature Seychelles has recently
completed a project to assess the status and management of invasive
plant species on small but important biodiversity islands of Seychelles
by using Cousin and Cousine as examples. Researcher Liz Dunlop, of the
Queensland University of Technology in Australia, led the work, which
was carried out in close collaboration with Cousine island management.
Back in the 1960s, the Seychelles Warbler or Timerl Dezil was probably
the most endangered bird in the world, with only a handful of birds
remaining. Cousin Island, the last place it survived, was purchased
primarily to save this unique bird. Much has been done by BirdLife
International to save the Warbler. Now, Nature Seychelles has been
working with our partners on Denis Island and scientists from the
University of East Anglia in the UK and Groningen in the Netherlands on
a major project to secure the future of our Warbler.
Domestic cats have been in the news recently in Europe.
Conservationists have been trialling some new techniques to try to
limit the depredations of pets and feral cats on different wildlife
species. There is no dispute about the volume of wildlife killed by
cats, but what is not always clear is the extent to which this results
in population declines of the species they are killing. Most species
are able to tolerate the impact of this depredation, because they are
evolved to cope with it.
Nature Seychelles is calling on the public to help with improving
knowledge of a unique Seychelles animal - the weird and wonderful
Seychelles chameleon (kameleon). The conservation body is seeking to
enthuse and excite citizens about the natural environment, especially
in finding out more about animals and plants found nowhere else on
