Survey reveals natural treasures of the Kimberley Islands

April 2009. An ambitious survey is revealing extraordinary details about the fauna, flora and ecology of the islands along the Kimberley coast in the hope they could play a key role in the conservation of the region’s native plants and animals.

Western Australia’s Department of Environment and Conservation (DEC) biologists are conducting a comprehensive biological survey of selected islands off the north Kimberley coast, focusing on fauna that is likely to be affected by cane toads and other mainland threats.

The survey team has completed two dry season and wet season surveys on 13 islands from Sir Graham Moore Island in the north to Augustus Island in the south, with a further survey of nine islands planned for this dry season.

Rich in frogs and snakes

DEC senior research scientist Lesley Gibson said the survey has so far revealed the presence of additional island populations of many animals, particularly snakes and frogs, and has more than doubled the species lists for most of the islands visited.

“We recorded a northern quoll on Adolphus Island, which is a significant record as this species has dramatically declined on the adjacent East Kimberley mainland,” Dr Gibson said.

The agile wallaby on Adolphus Island and Merten’s water monitor on Augustus Island were also recorded for the first time on Western Australian islands.

27 new species of snail – 1 new genus

About 63 species of land snails were also collected, with at least 27 undescribed species and one new genus found.

Dr Gibson said that while the mainland had been impacted by various threatening processes, the islands were largely protected. She added “Biodiversity on the mainland Kimberley is under threat from extensive dry season wildfires, feral animals, weeds, soil erosion and the imminent invasion of the cane toad. The islands support populations of plant and animal communities that are in relatively good condition and hence have high conservation value, but little was known before this survey about what plant and animal species occur on the islands.

Safe havens

“The survey is being conducted in the hope that intact ecosystems can be conserved and that in the future the islands could provide a safe haven for threatened species from the mainland. The survey is also contributing to the State Government’s $9 million Kimberley Science and Conservation Strategy by providing fundamental biodiversity information on the islands off the Kimberley coast.”

In an innovative effort to save endangered quolls from extinction, University of Sydney biological scientist Stephanie O’Donnell is feeding them poisonous cane toad sausages: here.

The tiger quoll is an adorable, carnivorous marsupial, sort of like an extra-cute Tasmanian devil with spots. Like most of the other weird marsupials, they’re only found in Australia, and they’ve been increasingly hard to find in the wild. In the Otway Ranges in southwestern Victoria, there hadn’t been a confirmed quoll sighting in more than 10 years — until last month, when a local homeowner saw one poop outside his laundry room: here.
