To celebrate World Environment Day on 5 June 2008, the Botanic Gardens and Parks Authority hosted the Official Opening of the Conservation Garden by the Hon. David Templeman MLA, Minister for Environment; Climate Change; Peel.

The Conservation Garden is a new half-hectare garden dedicated to Western Australia's rarest plants, which few people would ever have the chance to witness growing in their natural habitat.

The new Conservation Garden is a visual consolidation of many years of substantial work undertaken by the Botanic Gardens and Parks Authority (BGPA) to conserve Western Australia's unique plant biodiversity, including rare and endangered species, and to present this spectacular flora to local, national and international visitors.

"The millions of annual Kings Park visitors and the wider Western Australian community will be rewarded by having rare flora displayed in the heart of Kings Park," said CEO, Mark Webb.

"One of the main aims of the Conservation Garden is to build increased community awareness and understanding of the need to conserve our unique plant biodiversity, so together we have a stronger chance to protect, restore and conserve our special environment now and in the future."

Plants are essential to life on earth, providing oxygen, food, medicine, fuel, clothing and shelter. Two-thirds of the world's known 300,000 plant species could be threatened by the end of this century unless urgent steps are taken to safeguard them.

The Kings Park Conservation Garden, set within the Western Australian Botanic Garden, aims to display around 400 species of Western Australia's most threatened plants to help raise awareness of their threat of extinction.

Plants in the Conservation Garden are grouped in themes according to their region or habitat type, with a special garden dedicated to Western Australia's critically endangered species.
