Hamadryad- trees, ecology & FUNGI!

I was speaking to a lady this morning who is a botanist on one these discussion groups for the Government and she has cited and pushed for the Swedish approach. No final decision has been made at this point, it's stlll under discussion. The preventative idea is to stop human and related traffic carrying the spores further. This is not to totally prevent it, but to help reduce travel. It is accepted that air borne spores will still travel. Newspapers rarely give all the facts only what they think will make good reading.

...Note also the black exit of Inonotus hispidus, a fungi of biotrophic nature but smart as Einstein, because even though it can penetrate living tissues, it does so only occasionally to fruit, mostly living as a heart rotting fungi where it can live in long term happy harmony with the host. it does not pay to kill ones food source, give this some serious thought...

 

Very good point, and salient to the ash/chalara issue. Slash and burn is a policy we condemn in the tropics, yet carry out in our own communities, crazy. :thumbdown:

 

Nice work showing detail in paxillus and the other. How does this affect prognosis and treatment--how differently do these fungi act?

 

Nice work also pruning and documenting the walnut work. The first reaction might be "O No, too much off the top!" Yet note the sap risers left, and look ahead to the release of buds on the now-bare branches. How soon will the owner have you back to thin the sprouts and restore structure? 3 years, 5?

 

In the US I'm told "Well if you prune it like that you MUST be back to manage sprouts regularly, perhaps annually." This wild conjecture seems based on fear and loathing of sprouts, on the same order as fear and loathing of disease and wood decay fungi, and for the same reason--lack of familiarity. (which is a nice way of stating what is, literally, ignorance.)

 

My response is, if there is no return treatment, the tree will still be far better off than if it was not reduced, because it would likely have failed. The scenario of long epicormics catastrophically failing decades after reduction is impossible in some older trees, and very unlikely in most others. Just one return visit 5-10 years later to sort out the codoms and sprawlers will suffice for most trees.

 

If we do not agree with everything that goes on in the industry, we need to do something about it. There is a need for info that is far greater than any personal feelings or agendas. Our responsibilities to healthy tree systems far outweigh the concerns of individual bipeds. Carry on! :thumbup:

well thats not what the ICF chief said, they are ignoring the research of the swedes and going ahead with advising a scorched earth policy on Chalara, this is as weall seem to be in agreement on, totaly unacceptable.

 

Andy, good to hear this approach has been mentioned, just hope the government don't start playing politics with it all as they are wont to do. :thumbdown:

 

Fixus politicus has generally proven to be far more damaging than any natural threat.

Thanks, not a lot really, just that P.involutus could be acting soley as a saprotroph and therefore of little value in tree health (rhizosphere) prognosis, more so as it is a generalist and also present in the decline of trees.

I need not return in 10 years, a check up in five advisable

Leave a tree alone for a decade and most imbalances due to pruning are resolved by hormonal balancing.

learn to credit where its due and I might give you the benifit of the doubt!:001_rolleyes:

 

Good article Tony. Out of curiosity, if you had to put a % point on the reduction of the wallnut, what would you say?

 

I dont get into those conversations anymore, its so pre 2010! and so a wast of time,the sooner we stop talking % the better:thumbup:

With reference to Chalara in ash.

If you take a look at these pictures of Nectria in apple and compare the with the

chalara in ash symptoms they look very similar.

Nectria in apples has been about for years and yes it can kill the trees if not controlled, and yes it can be controlled without condemning the whole tree.

Nectria is more prevalent in cold and wet years, it can also depend on soil types witch intern affects the seriousness of the infection.

What does concern me is the corect ID of Chalara in the Ash canker in Ash can also look the same.
