The small meat-eating marsupial Agile antechinus
(pictured) is one of seven new mammals discovered in Australia since 1999.
Despite the new-species discoveries, habitat loss and degradation, invasive species such as the cane toad,
and pollution may be damaging the country's biodiversity, conservationists said in a report released in September 2009.
More than 1,700 Australian plants and animals are listed as threatened by the Australian government, WWF's Roache said.
"With the discovery of so many new and exciting species," he said. "It is crucial that efforts to keep them off the threatened lists are maintained."
