3 New Sites of Ash Die Back Found in Wales

Britain's ash die back continues to spread.

Three new cases have been found so far in 2013.

All three locations are newly planted areas in Wales.

The die back is being caused by a fungus known as chalara fraxinea.

It was first discovered, in the UK, on March 7, 2012.

Since then, it has spread to hundreds of sites all over England, Northern Ireland, Scotland, and Wales.

Chalara fraxinea was brought over by infected wood from the Netherlands, and since has been declared a national emergency.

Concern, over the spread of the fungus, is such that there's even an app to map locations where it has spread to.

The same fungus has killed over ninety percent of the ash population in Denmark.
