Wallum
The Wallum is an Australian heathland , typical of the southeastern Queensland coast . The wet, acidic and nutrient-poor soils are made of pure sand on water-impermeable sandstone . The vegetation of the wallum is seldom higher than a meter and rich in orchids , sundew , water tubes and stylidium . Specially adapted animal species live in the ecosystem of the Wallum, such as the parakeet , the frog Crinia tinnula , the Australian tree frogs Litoria freycineti and Litoria olongburensis or the rainbow fish relatives Rhadinocentrus ornatus and Pseudomugil mellis .
The Wallums are subject to extreme human settlement pressure . They represent a preferred building plot and are therefore threatened.
