PROJECT The Australian Arid Lands Botanic Garden
LOCATION Port Augusta, SA
LANDSCAPE ARCHITECT Grant Henderson
Designed by Landscape Architect, Grant Henderson and opened in 1996, the Garden’s role is as a national showcase for arid zone conservation. This is important as most Australian’s live in densely populated coastal regions and are unfamiliar with the flora and fauna of these areas.
The Australian Arid Lands Botanic Gardens at Port Augusta displays arid zone ecosystems in an area which receives an average annual rainfall of around 225mm per year. Winters are cool and Summer temperatures may reach has high as 48°C in the shade. This 200 hectare site contains one of the most intact remnants of Western Myall (Acacia papyrocarpa)and Chenopod plain, close to the city.
The landscape surrounding the Arid Lands Centre is made up of a network of circulation trails displaying a range of plants from different dry regions. The gardens have a largeEremophila (Emu Bush) display, featuring around 155 different varieties. This is thought to be one of the largest collections of this genus in Australia.
As water for the township of Port Augusta is transported from the distant Murray River, water harvesting is a strong focus in the Gardens. Water efficient irrigation methods are employed within the gardens and treated waste water from the Visitor’s Centre is used to irrigate parts of the collection.
