Palm Valley (Northern Territory)

Palm Valley in Finke Gorge National Park
Cycads (Macrozamia macdonnellii), Palm Valley, NT

Palm Valley, within the Alice Springs in the Northern Territory, Australia. Palm Valley and the surrounding area is the only place in Central Australia where Red Cabbage Palms (Livistona mariae) survive. The nearest specimens are 850 kilometres away in Queensland. The surrounding region is largely dry Central Ranges xeric scrub.

The average rainfall for Palm Valley is only 200 mm per year. Although the gorge usually appears dry, there are some small pockets of semi-permanent spring-fed pools that allow the unique flora in this region to survive. During significant rainfall in the region, expanses of water can be witnessed flowing through the valley gorge. During such events, a variety of aquatic life such as desert fish, shield shrimps (Triops australiensis), tadpoles and frogs can flourish.

Origins of the palms

It had been assumed that the cabbage palms were remnants of a prehistoric time when the climate supported tropical rainforest in what is now the arid inland of Australia. Genetic analysis published in 2012 determined that Livistona mariae at Palm Valley is actually the same species as Livistona rigida from samples collected near Katherine and Mount Isa, both around 1,000 kilometres (620 mi) away. The research by Professor David Bowman and colleagues at the University of Tasmania concluded that the populations separated only about 15,000 years ago.[1] Aboriginal legend recorded in 1894 by Carl Strehlow describes "gods from the north" bringing the seeds to Palm Valley.[2]

Getting there

In early 1928, Herbert Joseph Larkin led an exploratory aerial expedition exploring the possibility of developing the Palm Valley into a resort. However, the exploration led to naught.[3]

The track to Palm Valley is still only accessible with a four-wheel drive vehicle. It departs from the town of Hermannsburg and travels south, following the usually dry bed of the Finke River. Palm Creek flows into the Finke River from the west about 15 km (by track) south of Hermannsburg. The track follows the creek to Palm Valley about 5 km west of the Finke River.
