Commemorative Issue: Threatened Wildlife
Australia does not enjoy a good record for nature conservation. It is ranked fifth in the world for species extinction on the World Conservation Union's Red List. Exotic weeds and pests; habitat clearance; soil erosion; the over-exploitation of rivers;
the spread of urban Australia; the pollution of air, soil and water; climate change and salinity are among the challenges facing the conservation of Australia's bio-diversity.
