    Recent news is rather worrying , seems it's just a case of time before the fungus spreads round this country.
    Anyone know does it effect all Ash species? (Rowan etc.)

    Hi,
    I saw an article on the news that said the main method of spread was wind born(from Europe). And they are modelling from this the likely areas to be affected. But a very worrying situation.

    There are lots of mature Rowans (Mountain Ash) where I live as they were part of the original developer's landscaping proposals.

    I have been checking up and they appear to be unrelated to the common ash - so hopefully they won't be affected.

    I used to regularly climb a particular ash tree when I was young (well before Elf n Safety!) and made rope swings etc. It's still going strong and I really would hate to see it being harmed - I still see it as 'my' tree.

    End of nostalgic interlude.

    Elm, oak, spuce, now ash - is this the first really noticeable effect of climate change, world trade, the internet or whatever decadent feature of modern life it turns out to be? The countryside still seems so blooming abundant otherwise, it's hard to believe that disaster is looming.

    And larch (phytophthera). Didn't know about spruce. Apparently one of the reasons elm was hit so hard/fast was because elm propogates itself vegetatively by suckers, thus, all being clones, there is little or no genetic diversity, and therefore no chance of developing resistance. I'm hoping that ash, which propogates readily from seed may do better in this regard.

    If not, the valley I live in in west Wales is going to be seriously denuded - about 60% tree cover of which about 30% is ash.

    Don't panic! - I meant larch not spruce

    When will the bug-resistant strains of Elm, nursery stock currently being grown, make significant appearance? Can't wait!

    There was a piece on the midday news showing Dutch towns that were re-planted with disease resistant Elms long ago.

    It is hoped movement of ash will be strictly controlled to prevent spread, we had a magnificant elm which we tried to protect with repeated treatment but lost it . A neighbour had gathered 4 years of fuel from scavenging fallen elm over a large area to feed his woodburnerf!
    Does de-barking remove the hazard content because removal also helps on emissions impact?
    Another reference below!

    This disease has been advancing across Europe for at least twenty years now and it didn't take a genius to realise it would sooner or later reach here if nothing was done. Yet the government did precisely nothing until it was actually here.

    The trouble is the government places the interests of some importers who would be inconvenienced by import restrictions higher than that of the general public. Therefore to save importers a paltry sum we have to put up with the disease spreading and all the (much higher) costs associated.

    Forestry commission website says Rowan aka Mountain Ash is a different species and not affected.

    From their Q's and A's
    "What advice do you have for the public?
    We welcome reports of ash with Chalara dieback symptoms. We do ask that you take care first to ensure that the infected tree really is an ash, because they can look very similar to rowan trees, which do not get the disease. (To add to the confusion, rowan trees are sometimes called mountain ash.)"

    everything i have read says that this didease is carried by the wind, including across the english channel.

    but if this were so would it not have spread much faster? If it could stay airborne over such a distance then it would travel hundreds of miles in a short time frame. I think this maybe certain parties trying to push this idea in order to deflect away from having failed to act to prevent its entering the country.

    I've got a good idea.

    Let's convert one of our largest coal fired power stations to biomass fuel instead. Let's leave huge piles of imported (from everywhere in the world) woodchips outside and see what happens!
