Agriculture Minister Michelle O'Neill has emphasised the need to be alert to the threat posed by the tree disease Ash Dieback.
Urging people to report any suspect symptoms to her Department, the minister said: "Ash Dieback is a serious tree disease and the ash tree is of particular landscape, environmental, and cultural value in Ireland.
"We all have a part to play in tackling this disease. Unless it can be prevented, the consequences for our landscape will be significant.
"I want all farmers, forest owners and the wider public to be vigilant for the signs of this disease and quickly report any suspect symptoms they see to the Department."
