Photographer's Note

I could not find any list of the rapidly growing number of fern species that are now extinct.
Before the extinction process begun, there were supposedly twelve thousand species of ferns.

Some of them are visible in this photo, at the heart of the World Hydropolis.
Among them a young Cyathea brownii, together with Cyathea intermedia, one of the two tallest species in the world, visible behind a even younger Howea forsteriana palm.
It is a native of tiny Norfolk Island, the natural habitat is above 100 m elevation, a climate found elsewhere in the world - at slightly different elevations - only in Lord Howe Island, Raoul Island, Azores Islands and Madeira Island.
Only in this climate it is possible to reach the maximum height of 20 m. Currently such specimen exist only in Norfolk Island.

Except for yearly precipitation, which is in fact above 1500 mm, Wikipedia correctly describes this climate:
Average daytime temperatures reach around 23 °C during the summer months falling to around 17 °C during the winter. The highest temperatures likely to be experienced in this environment are around 29 °C, the lowest around 6 °C. Relative humidity is fairly consistent at levels between 70 and 80% throughout the year. Yearly rainfall is approximately 1200 mm .
