WA’s biodiversity explored

The 230-page non-fiction book explores the South-West of Australia, a land triangle that encompasses a multitude of natural worlds.

Called The Southwest, Laurie has explored the biodiversity hotspot on the coastal plain of Western Australia which is home to a third of all known Australian plant species.

The region has been designated "Australia's Global Biodiversity Hotspot", one of only 34 such habitats in the world and the only place across Australia to be recognised for its diversity of species.

Laurie presents the voices of scientists and those dedicated to protecting a fragile ecology supporting up to 150,000 species and has asked residents in the Shire of Kalamunda passionate about biodiversity to spread the word.

One of the most enduring tales in the book is of spider expert Barbara York Main, who has a favourite trap door spider she visits each year.

Ms York Main's fascinati on with spiders came about when, as a child, she noticed domed pebbles on the ground which were actually the lidded doors of a trap door spider's home. "The Wheatbelt has the highest endemism," Ms York Main said.

Her oldest favourite spider is at least 40 years old.

Laurie asks how she knows the spider is the same one situated in a Wheatbelt Nature Reserve.

"They don't ever move out once they build a home," she said.

"And no other trapdoor spider moved in."

Laurie is a long-time resident of Gooseberry Hill and a member of the Natures Reserves Preservation Group.

"The environment needs our help to protect threatened and unique species and lifeforms not found anywhere else," she said.

"Because of the isolation of this State, there are lifeforms and landscapes in the region that have evolved with abundant biodiversity."

Environment Minister Albert Jacobs launched the book this month at the University of Western Australia.

"It should be required reading for every politician in the State," he said.

Laurie said she is motivated by concerns for the threats to the ecosystems that surround West Australians.

This compelling book confirms the South-West of Australia as one of the most intriguing places on earth.

In 2010, the author published The Kimberley: Australia's Last Great Wilderness.
