In pictures: Photographing Australia's tallest trees

Photographers have scaled towering eucalyptus trees in Tasmania for a spectacular art project.

One of the world's tallest trees, eucalyptus regnans dot the state's Styx Valley, 90km (55 miles) northwest of Hobart.

The species, which is the tallest flowering plant, is also known as mountain ash or swamp gum.

The photographers hope to draw attention to some of the world's largest and most unusual trees.

"It's purely about awareness," photographer Steven Pearce told the BBC.

The team suspended a camera between branches to photograph the eucalypts, which can grow to almost 100m (328ft).

Mr Pearce said he became interested in trees through his wife, ecologist Dr Jen Sanger, who studies plants that grow on other plants.

The trees in the valley have Lord of the Rings-themed nicknames, including Fangorn and Gandalf's Staff.

The Tree Project team spent 67 days on the project, which is now on display at the Tasmanian Museum and Art Gallery.

"For our next project, we're planning shoot a tropical rainforest tree 94m high in a place called Danum Valley in Borneo," Mr Pearce said.
