Invasive species a huge threat to sparse ecosystems, scientists report
FRISCO — The tiny ice-free fringes of Antarctica are especially prone to ecosystem disruption, including invasive species, an Australian science team warned earlier this year after taking a close look at how human use is concentrated in those slivers of dry land.
Antarctica has over 40,000 visitors a year, and more and more research facilities are being built in the continent’s tiny ice-free area. Most of the Antarctic wildlife and plants live in the ice-free areas – and this is also where people most visit.
Most tour operators in Antarctica follow strict guidelines set to protect ecosystems, including at least basic decontamination procedures, but those measures might not be enough, especially as global warming makes ice-free zones more susceptible to invasive species. Continue reading
