Ruben was captured from a low tree by a main highway, in an area where koala habitat is being encroached upon by urban sprawl. Koalas near main highways, are at high risk of being hit by a car when moving amongst trees. REUTERS/Loren Elliott SEARCH "KOALAS ELLIOTT" FOR THIS STORY. SEARCH "WIDER IMAGE" FOR ALL STORIES
