Die-back kills off 90% of Denmark's ash trees. Britain faces a similar threat

[benedmonds]

From the Observer today:

 

A killer fungus has attacked ash trees across northern and central Europe, prompting pleas for the UK to ban sapling imports. But it may already be too late

Looks like work could pickup then, every cloud and all that.

First the Elm, now the Ash, and maybe the Chestnut is up next for virtual extinction.

 

It's sad loosing bio diversity, but it provides a steady flow of work.

Was in Norfolk with a fellow arbtalker a few weeks ago and couldnt help but notice the poorly Chestnuts with browned off leaves . Whats going on ? Havent seen it up here ..

Surprised you say you haven't seen it up in your area, as I'm fairly sure I as it on a horse chestnut at balmoral a couple of years ago.

 

Guess there aren't big numbers of chestnut around there ?

 

 

One thing that will be interesting with the predicted demise of the ash (which I'm not totally signed upto yet) is how the species of fungi associated with that tree might react. I wonder if we'll see a shift in the host range of Inonotus hispidus, Daldinia & Perenniporia.

Taken from an article on the woodland trust website. A ban on imports of Ash trees as early

as November?

 

Dear Supporter

 

We said that we would give you an update on ash dieback as the situation develops. The disease causes leaf loss and has already killed millions of trees in parts of mainland Europe.

 

The Woodland Trust took the lead on calling for an immediate ban on the import of ash trees. We are pleased that our stance has gained such a positive response in such a short time frame.

 

Yesterday Environment Secretary, Owen Paterson said that a ban on imports of ash trees to combat the threat of the tree disease Chalara fraxinea could be in place as early as November. Owen Paterson stated:

 

"This disease could have a devastating impact on our native ash trees so we need to take action to stop it. We are working towards a ban on imports, and looking to impose movement restrictions on trees from infected areas."

 

This growing crisis shows how important it is for the government to adopt the independent panel report's recommendations around accelerated action on tree diseases. A consultation on managing the threat to the UK's ash trees is due to end on 26 October. Details of the consultation document can be found here.

 

It is possible that a ban could come into force before the main planting season gets underway in mid November, which would be a really positive step. The Government will work with the industry and those that grow or trade in ash plants to minimise the impact a ban will have on their businesses.

 

Norman Starks, our UK Operations Director in response said:

 

"This is not a minute too soon. The Trust called for a full immediate ban on imported ash trees last week and welcomes the consultation. We expect a decision to be made swiftly and decisively following the 26 October deadline before the tree planting season starts. The Trust will no longer plant imported ash trees on our estate and is reducing the number of ash to be planted this season by 100,000 trees. We are committed to working with the industry to do everything possible to prevent the further spread of ash dieback and protect one of the nation's most common native trees."

 

The Government went on to state that all infected trees are being destroyed. Ash trees in the vicinity of infected sites are also being monitored by the Plant Health Authority to ensure early detection of the disease.

Thank you for the link David , interesting little geezer .

 

Plenty of big horse chestnuts up here but certainly not in the concentrations of Norfolk ( bearing in mind i only seen a small part ) . I certainly havent seen this locally but will lookout for it . Loved the big willows down there aswell , beautiful

Wouldn't want to be without ash trees it's a sad case

Hed these sent to me the other day:

http://bfw.ac.at/400/pdf/fsaktuell_44_7.pdf

It seams according to some of the research that:

If it turns out that actual tree death is not that common (even the FC "pest alert" note states the disease causes leaf loss and crown die back and that it may lead to tree death) it actually sounds unlikely to "spell the end for the common ash across Wales", but could spell the end of production of good ash timber.

Don't believe the hype generated by the newspapers

My Missus is off to Copenhagen to to check on this today! No really she off to Copenhagen to see her sick father, but she will look into to the Ash problem while she,s there.
