Are Kangaroo Island's koalas under threat?

Wed, 10/26/2011 - 02:58 — Anonymous South Australia's Kangaroo Island
takes its name from the mobs of kangaroos that graze its dense bush. Koalas
were introduced in the 1920s, and flourished so spectacularly that at one
point it looked like they might overrun the 4,405*-*square-kilometer island.
But now the koala colony could be under threat. An AIDS-like retrovirus has
made its way from the mainland and been detected on the island. Some expert
warnings are dire: it could eventually wipe out the population. The Koala
Research Network told a recent Senate inquiry the disease is spreading
through the island like wildfire. var OutbrainPermaLink =
