tree felling
Hi, did some tree felling recently in order to thin out a plantation of
200 trees, the free was a turkey oak abour 15ft tall and disfigured. when felled to make way for other better specimens the remaining logs and stump had black veined stains. I have never seen this before. Does anybody know what it is? |

Only a specialist could make a decent guess at which fungus, as there are a lot of possible candidates. Regards, Nick Maclaren. |

Dear Nick, Thanks for your input, I am about to do some research on fungus mycelium. thankyou very much. Steve |

I have never seen this before. Does anybody know what it is? Hi, I don't know what it is, but I do know there is a newish disease called 'Sudden Oak Death' (Ramorum sp??). I think it is a notifiable disease (someone here will know for sure), which means reporting it to DEFRA. Although called 'Sudden Oak Death', it does attack other woody plants, so it may be worth some research *and* checking other woody plants in the area which are showing signs of sickness. Spider |

Dear Spiderand everybody else. photographs are being e-mailed to the
forestry commission who deal with the disease that you mentioned. I await their reply. The office in Scotland has been concerned and has conducted a telephone interveiw with ourselves. Thankyou for your interest. steve |

penance! I have just heard that the forestry commission beleive it is
not anything to do with Sudden oak Death SOD, however they are still going to investigate it. I would like to show the photos at a later date and report back on the result. Thankyou for your interest in this puzzling subject of which I have limited knowledge . Steve. |

The symptoms you describe are very common indications of fungal infestation. As I implied, whether the colour is the mycelium or due to chemicals released by the mycelium reacting with the wood, or something even more complex, is beyond my knowledge. If the Forestry Commision are investigating, they will know that, and will be interested in finding out WHICH fungus (or whatever). Note that the symptoms of infection by fungi, slime moulds and bacteria can be indistinguishable, though the organisms are much less closely related than we are to flatworms. So it would not amaze me to discover that it was not fungal, but bacterial. Regards, Nick Maclaren. |

Hi, just a quick reply to your thoughts, The site is 23 acres and no
other symptoms have been seen. The site has no Rhodo's and has 13,000 trees the majority of which are 10-12 years old. The scaring on the bark has been with this sole tree for 5-6 years and the leaves and branches have appeared to be healthy. I await the reply fro the FC. Thanks for your help.Steve |

I have felled many trees that display the signs of chemical compartmentalisation, sometimes the tree can appear perfectly healthy, and often is, but obviously it may be more sinister. Pictures would be helpful.

And, as Rackham points out, fungal infection of the heartwood is a normal part of many tree species' development, and is NOT biologically unhealthy! Though it is undesirable from a forestry point of view .... I would hesitate to guess in what proportion of trees with fungal infection and chemical compartmentalisation the former was the cause of the latter (rather than both being the result of some third 'attack'). So identifying the cause needs more effort than just looking at the damaged tissue under a microscope or culturing samples and looking for fungi/bacteria/etc. It's like my personal hypothesis of coral spot - i.e. that it is NOT generally the cause of the branches dying back, but gets the blame because it infects the bark immediately it starts to die from another cause. Yes, that could be investigated, but it would need expensive laboratory work. "The truth is rarely pure and never simple" Regards, Nick Maclaren. |

dear Nick I didn't expect such a response as the new boy, however am I
right in understanding that compartmentalisation is the staining which acts as a barrier to the infection of fungus? I think thats it. So you are saying( I think) that there are many trees that are standing that are fighting infections with a barrier as we speak. In addition, to find out the cause of the fungus would be very difficult and expensive because?.............. I would like to know your thoughts. However how marvelous that a tree has the natural ability to defend foriegn elements and try and survive until I cut it down without finding the cause first!!!!!!. You like my self are interested in the result. Which I will publish on another link in days to come. Regards, Steve |

Some wood workers like this effect - and in timber is known as Spalted,
hence spalted beech, etc Further info can be found at http://www.thewoodbox.com/data/wood/spaltedinfo.htm |
