Pictured: Symptoms of Chalara ash dieback. A fungal disease affecting the ash trees of Europe. Picture shows a wedge-shaped lesion caused by the pathogen working its way into the tree.<br />
Re: Millions of diseased trees near buildings, roads and railways will have to be cut down because of a deadly fungus which is spreading through the ash trees  in the UK, a lot quicker than anticipated.<br />
Natural Resources Wales (NRW) warned of a "very significant impact" on the landscape and the Welsh government is setting up an expert group to advise on the issue.<br />
Wales has been particularly affected by the spread of ash dieback, which was first identified in the UK in 2012<br />
Its proper name is Chalara dieback, named after a fungus called Chalara fraxinea<br />
Symptoms include lesions at the base of dead side shoots, wilting and lost leaves and a killing off of new growth on mature trees<br />
The disease is spread by released spores and has swept across Europe over the past 20 years, affecting about 70% of ash in woodland<br />
Ash is an important species for nesting birds, insects and fungus<br />
It does not pose a risk to human or animal health
