In what may be a world first, scientists are planning to release native bush rats into the Sydney
suburb in an attempt to force out vermin black rats. If successful, it could be the opening shot in
a war to drive the pests out of suburbs across the city.
Black rats, unlike the more benign native rodents, invade houses, chew on wiring, carry diseases
that can spread to humans and wildlife, and climb trees to devour eggs of native birds.
They are thought to have invaded Sydney with the First Fleet, Grainne Cleary, a Taronga Zoo
ecological researcher, said yesterday.
