The future of Cwm Idwal
One of the main challenges facing the fragile and unique environment of Cwm Idwal is climate change It is thought that the earth is warming at a rate of 0.3ºC every decade and as Cwm Idwal has been home to a number of Arctic-Alpine plants since the end of the last Ice Age, climate change could have a devastating effect on the species that call it home.
One study by Northumbria University whereby a new model of the sun’s movement was created suggests that two different movement occur in the sun and when both move ath the same time, a ‘mini ice age’ will develop in the 2030s! Only time will tell if this comes to fruition, spelling good news for Cwm Idwal’s Arctic-Alpine plants.

Climate change isn’t the only threat to Cwm Idwal. High visitor numbers pose a daily threat to the conservation of the area. We have to be careful that we adhere to rules and guidance to minimize erosion and safeguard the rare plants.
Please bear in mind the fragility of this special valley when visiting. Remember, enjoy and respect.
