An 18-day long survey was carried out on Lacrosse Island and Buckle Head, two islands in the Kimberley. The survey has unveiled about unknown threatened native species like the northern quoll and a tree-rat.

The Western Australian department of parks and wildlife and Balanggarra Rangers conducted the survey using traps and camera sites. The survey was a part of the WA government's Kimberley science and conservation strategy.

The officials and rangers have found a huge population of northern quolls. This species has been majorly affected by invasive species like feral cats and cane toads.

Rock rat was found on both islands and water rat was spotted on Lacrosse Island. Survey was also done on a mainland site nearby the islands. On all the three locations, the giant slender blue-tongue skink was also found.

Generally, giant slender blue-tongue skink is found in the northern part of the Kimberley. Officials found tree-rate on Buckle Island. This species is said to exist only on nine other islands in the Kimberley.

In the camera, a bandicoot was also captured. But for now, it is not known whether it was a golden bandicoot, a threatened species, or a northern brown bandicoot, which can be generally found. Researchers also found chewed Owenia nuts. As per them, they must have been eaten by the scaly-tailed possum, which are present in large number in the area.

Albert Jacob, WA's environment minister, was of the view, "The state government's $81.5m Kimberley science and conservation strategy is a bold vision for the Kimberley's long-term conservation and will provide unprecedented protection for the region's unique plants and animals, as well as creating tourism opportunities".

Jacob further stated that for the first time, surveys have been carried out in these areas. All the three sites had almost similar diversity of species.
