An Australian study of species at risk finds about 1,200 of the 5,457 species of birds, mammals and amphibians examined face almost certain extinction.
The new research, published in PLOS Biology, maps “hotspots” where species are most affected by threats such as agriculture, urbanisation, night lighting, roads, rail, waterways and population density, and “coolspots” that provide refuge from these threats.
The team looked only at threats that were known to affect a species within its habitat range and found that for the majority of wildlife studied, intrusions were “extensive” across most habitat, “severely limiting the area within which species can survive”.
They said most concerning was their finding that 1,237 species – nearly a quarter of the animals assessed – were affected by threats across more than 90% of their distribution.The countries most affected are in southeast Asia.
The same study group mapped the remaining wilderness areas. It looks like this:
Green and blue, that's it.
