Confirmed findings at 8 November 2012:

Nursery sites – 15
Recently planted sites – 55
Wider environment, e.g. established woodland – 65
Total: 135

Plant health experts are also undertaking an urgent survey of about a thousand sites which have received saplings (young trees) from nurseries where Chalara dieback has been found. They are also prioritising the examination of about 2500 blocks of land, each 10 kilometres square, where mature ash trees are present, to check for traces of the disease in established trees.
