Trees in Wales' largest area of ancient woodland - Wentwood Forest near Newport - are being felled due to a devastating disease.
The Woodland Trust says larches in have been attacked by Phytophthora ramorum, which can damage and kill trees.
Work has already begun to remove 500 acres of the woodland.
The disease is already affecting thousands of larch trees elsewhere in Wales, the South West of England, Ireland and Scotland.
