Ash tree disease Chalara dieback is found at six sites in Wales
Forestry Commission Wales says a disease which kills ash trees has been found at six newly-planted sites.
Chalara dieback of ash has been confirmed at five sites on Forestry Commission land in Wentwood and the Wye Valley in south east Wales, and at Glynllifon college in Gwynedd.
A survey of other sites recently planted with ash from known infected nurseries is continuing.
Earlier this month the disease was discovered in Carmarthenshire.
