I think this fits in here,
Where are the rainforests? The Amazon? South-east Asia? How about mid and north Wales?
In fact, Wales is home to some of the last remaining examples of temperate rainforests in Europe. A rainforest is defined as any woodland that thrives in conditions where there is over 200cm of precipitation a year. While the flora and fauna of temperate rainforests differ from their tropical counterparts, they act as both a vital source of biodiversity and a massive carbon sink.
Another similarity they share is the inspiration for thousands of years of legends and folklore, many of which have a basis in scientific and geographical fact and act as cautionary tales about our misuse of the environment.
"Although tales in Welsh folklore, such as the Mabinogion, are mythical, the places and environments they describe are very real indeed," according to Dr Juliette Wood, an expert in Welsh folklore at Cardiff University.
"They provide specific locations which can still be found today, and offer insights into how people interacted and managed the land on which they lived."
In Wales, there are four main areas of rainforest: Eryri, also known as Snowdonia, in Gwynedd; Cwm Einion, in Ceredigion; Cwm Doethie-Mynydd Mallaen, in Ceredigion and Carmarthenshire; and the Elan Valley. At their height 8,000 years ago, they helped form one contiguous forest from Wales to Scotland, and as recently as Roman times, provided a "Celtic super-highway" for the native Britons pushed north and west by the conquest.
Today they are managed by Celtic Rainforest Wales, a partnership of several woodland and wildlife charities funded by a nine-year EU grant.
At its peak, the rainforest would have covered 75% of Wales, according to Gethin Davies, senior manager at Celtic Rainforest Wales.

"From a low of less than 5% [rainforest coverage] at the turn of the 20th Century, slowly we're clawing it back towards 10%," says Gethin Davies, of Celtic Rainforest Wales
"They include a mix of oak, ash, hazel, birch and willow, and provide a habitat for hundreds of species of wildlife, most famously the endangered horseshoe bat and pine marten. Historically they have been devastated by deforestation for farmland and timber, but today the biggest threats are climate change, human activity on the ground, and especially non-native species."
Possibly even more vital than the trees themselves is the ground-level ecoculture, which thrives in the dark and damp conditions under the canopy, which includes mosses, lichens, ferns and fungi. As well as retaining moisture for tree roots, these low-lying species act as an early warning system when the health of the forest is threatened by invasion, drought or air pollution.
While manual or herbicidal removal of invasive plants is possible, Mr Davies said they can sometimes do more harm than good to the ground flora. ...
