Another question, should we taking the dogs out in the local woods? with this phantom dog killing disease and dieback maybe it would be a good time to put more dog poo bins around the rec!

Latest info from the Forestry Commission:

Confirmed findings at 9 November 2012:
Nursery sites - 15
Recently planted sites - 55
Wider environment, e.g. established woodland - 114
Total: 184

These latest figures show that the number of confirmed cases in established trees has virtually doubled within the last week, this though is largely due to increased public awareness and better reporting methods.

Seasonal canine illness is not at this time thought to have any connection to Chalara fraxinea, latest tought is it may be caused by a mite or tick. Preventing the spread of Chalara fraxinea is at this time very much a topic of conversation as there is some evidence that with the confirmation of the disease on UK soil that that control or eradication is not a real option anymore, plus there is no no known way to protect the trees once infected so we really are at a point were the only discussion is that of how we look forward past the destruction and prepare for re population of the UK with Ash.

Until now the priority has been to destroy infected tress to prevent spread, however as with Elm there is some argument that by burning infected trees you only prevent the inevitable. It's also worth mentioning that with Elm there was a slow demise in population and although the vast majority of trees succumb to the beetle which caused the disease not every one was killed, as marginal number of trees were found to either have an immunity or some other form of resistance... and its very trees that are now the key to the propagation of the Elm being reintroduced back British countryside (its worth mentioning that Dutch Elm Disease was never eradicated either! from the time 20 years ago when it had its major impact there has been several smaller outbreaks the last I remember in 2010).

There may be another case not to far away, this outbreak is in young tree stock in the Wimpole Hall area of Cambridgeshire apparently.

I have not updated this for a while, the latest figures are.

Confirmed findings at 4 January 2013:

Nursery sites - 17
Recently planted sites - 156
Wider environment, e.g. established woodland - 166
Total: 339

I am told that the number of cases being found in new planting has now stabilised however the number of cases in found in establish woodland has risen yet again, the latest outbreaks are concentrated along the Eastern side of the UK with Norfolk and Suffolk being hit the hardest.
