Four youngsters from the Rhondda and Cynon Valleys will help plant up to a 1000 tree saplings on a disused colliery site in Maerdy as part of the Cwm Glo Cwm Gwyrdd series.
Nia Rossiter, Dafydd Francis, Gemma Starkey and Luke Smart will be joined by the series' presenter, naturalist Iolo Williams. Pupils from Ysgol Gyfun Y Cymer, Ysgol Gyfun Rhydywaun, Ferndale Community School and Maerdy Infants and Junior schools will also take part in the tree planting on 14 and 15 October.
Iolo Williams said: "I've been really impressed by the way the four young people taking part in this series have embraced the opportunity to go green. Over the series we see them develop and up their game – both in terms of enthusiasm and commitment.
"I'm also delighted we've been able to progress the tree planting scheme, which will help improve the environment in the long term, making a real difference to the local community in Maerdy."
Ros Davis, Communities First Coordinator, said: "Its great that children and young people are being given the chance to help create this wonderful new woodland. Hopefully they will help to take care of the environment in the future."
