Egged on by Darwin, in 1847 Hooker advised the Royal Navy to set in motion an elaborate plan. With the help of Kew Gardens - where Hooker's father was director - shipments of trees were to be sent to Ascension.
The idea was breathtakingly simple. Trees would capture more rain, reduce evaporation and create rich, loamy soils. The "cinder" would become a garden.
So, beginning in 1850 and continuing year after year, ships started to come. Each deposited a motley assortment of plants from botanical gardens in Europe, South Africa and Argentina.
Soon, on the highest peak at 859m (2,817ft), great changes were afoot. By the late 1870s, eucalyptus, Norfolk Island pine, bamboo, and banana had all run riot.

"The island originally had its own native flora until Portuguese explorers released goats in the 1500s which ate much of it. The later introduction of rabbits, sheep, rats and donkeys, and over 200 imported species further marginalized the original flora. [14] By 1843 the island was barren with few plants."
So it's not like it was inhospitable. We messed it up and then we tried to fix it and were mildly successful.
Makes me think of the Great Lakes. In the late '70s, they were practically sludge... but concerted effort has re-shaped them to be like they once were.
I only hope we can do that with the rest of the world we've messed with.
