Victorian terraforming

A lonely island in the middle of the South Atlantic conceals Charles Darwin's best-kept secret.

Two hundred years ago, Ascension Island was a barren volcanic edifice.

Today, its peaks are covered by lush tropical "cloud forest".

What happened in the interim is the amazing story of how [Darwin], Kew Gardens and the Royal Navy conspired to build a fully functioning, but totally artificial ecosystem. . .

Dr Dave Wilkinson is an ecologist at Liverpool John Moores University, who has written extensively about Ascension Island's strange ecosystem.

He first visited Ascension in 2003.

"I remember thinking, this is really weird," he told the BBC.

"There were all kinds of plants that don't belong together in nature, growing side by side. I only later found out about Darwin, Hooker and everything that had happened," he said.
