In 2015, the Woodland Trust bought Ceunant Llennyrch, a 220-hectare (550-acre) Celtic rainforest in Snowdonia. [13] In 2018, £8.5 million from the European Union and the Welsh Government were provided to support the areas of rainforest in Snowdonia, Cwm Einion, Cwm Doethie and the Elan Valley. [14] [15] [16]
The principal plant communities of the Celtic broadleaf forests include: [1] lowland to submontane acidophilous oak forests, mixed oak forests, principally of English oak (Quercus robur) and sessile oak (Quercus petraea). mixed oak-ash forests. Plant communities with smaller areas include: western boreal and nemoral-montane birch forests,
Today, the remaining fragments of Celtic rainforest are protected for conservation and research. [4] Since the 20th century, conservation efforts have resulted in the protection and management of many of these woodlands, to address problems such as invasive Rhododendron, excessive grazing from sheep and deer, and non-native plantation trees.

The Dolmelynllyn Estate is approximately 5 miles (8.0 km) north of Dolgellau, Gwynedd, in the southern area of the Snowdonia National Park.It is over 500 hectares (1,200 acres) in extent and includes landscapes that vary from river terraces to high moorland, as well as boulder-strewn woodland.
At one point, the river is flanked by one hundred feet (30 m) high cliffs, which face each other only 10 metres (33 feet) apart. The high humidity offered by the falls creates the perfect environment for numerous damp-loving plants, due to the high humidity and high rainfall, it is technically a temperate rainforest. [1]
Ninety percent [citation needed] of the Celtic forest habitat has been destroyed, generally over the last few thousand years, due to agriculture, fire-wood use and general deforestation. The outcome is an ecoregion which has not only lost most of its pristine cover, but which has been heavily degraded by fragmentation.

Following the last glacial period, trees began to recolonise what is now the British Isles over a land bridge which is now beneath the Strait of Dover.Forests of this type were found all over what is now the island of Great Britain for a few thousand years, before the climate began to slowly warm in the Atlantic period, and the temperate coniferous forests began retreating north into the ...
