Professionals in the plant nursery and tree-care sectors are being urged to check on the health of recently planted ash trees, and notify any symptoms of Chalara dieback of ash, a destructive disease only recently found in Britain for the first time. http://www.forestry.gov.uk/newsrele.nsf/WebNewsReleases/49016E712AD...
Thanks for the update
- I can not seem to find any information about the recovery chances / prognosis of infected trees - do they ever recover or is it similar to Phytopthora Ramorum in effect? IE. total loss of the infected population?
These posts on another forum show more detail of what to look for though;
Defra have said that a decision on whether to impose a ban on the imports of Ash trees will be taken tomorrow 26th October. http://www.defra.gov.uk/news/2012/10/04/chalara-fraxinea/
Interestingly the The Horticultural Trades Association called for a voluntary temporary ban on importing ash trees back in 2009 but was told quarantine action could not be taken because the disease was already present and widespread in the UK.
It’s very sad to think that another native tree could go the same way as the Elm.
Just look at Phytopthora Ramorum for the damage a rapid spreading disease species can do - albeit in that case to a non native (although still massively important ecologically and economically to the UK).
I Still cant find any infomation (3 months on) on the prognosis and nature of this disease? Anyone have any info on how it is spreading - It would be a shame if control was as lax as with Phytopthora - where the public still has access to woodlands which are infected - and helping the spread - Would be nice for some joined up thinking to take place.
