To try and protect the red squirrel population from their grey counterparts, the Welsh Government is consulting on a  draftGrey Squirrel Management Action Plan, produced with NRW and squirrel specialists. NRW has also produced a Forest Management Plan for Clocaenog which dictates when and where trees can be felled without causing detriment to protected species there.
