Ganoderma resinaceum decay information

Hi, has any one got any information on Ganoderma resinaceum with regards to wood decay or any one involved into how to manage a tree with this fungi? This large turkey oak below may be for the chop and am keen to present some good information to support the conservation of this tree (if after analysis things are supportive of this). I understand that the wood decay is similar to other more common Ganoderma species (base and root white rot) but have read different accounts about how vigorous this is with resinaceum. Thanks steve

The management issues are oftentimes by their very nature complex, involved and associated....I am not going to do the work for you but hope that you can find the attached pdf of some value....its all the more interesting anyway if you can afford the time to read and reach your own conclusions imo.

Additional reading that is both current and specific to Ganoderma spp can be found in Schwarze new publication also.....try doing a search " Francis MWR Schwarze...." I need to look up the title to be honest but Treesource list it a available

I hope this helps.....

My understanding of G resinaceum is based on the below and reading various text, mainly Lonsdale. Where it states that it can lead to more complete breakdown of the cellulose compared to other G spp, which increase the risk of windthrow or stem breakage depending on the predominant locality of active decay.

Having said this I have retained this large Ceris which has sound butresses around a large basal cavity, allbeit with heafty topping and inspect every three months with sounding hammer on the trunk & root butresses.

Guess you're going to have to weigh up the amenity value against your targets.

Thanks this is a big help. Cheers steve

Cheers for picture and info. Targets are students on a busy foot path through the park to the uni. Amenity value is high as this turkey oak has a nice big open balanced crown and its crown is in good health. How much decay within the roots of your turkey oak is apparent? cheers steve

Only minimal hand digging around base of butresses, no air spade.

Original reduction 4/5 years ago now.

Believe the decay to be, as is shown in below post, mainly in and around the basal cavity which extends 1m or so up in to the core of the Tree.

This was originally indicated by the use of an Arborsonic (quadrant cores can be seen in the 3rd post above) before the openings to the cavity became apparant.

here's a couple more shots from an older thread

thanks good one. Ok so, I need to get some idea of the degree of decay within the butress/stem then I may well get back in touch. Also will have a explore round the roots. Cheers steve

Here's a Red Oak I looked at today.

No sexy shot of the annual bracket I'm afraid, as someone whipped it away after I first saw it a few months back.

As you can see, the Tree has a major lean and evidence of a previous root plate lifting.

Carried out A Digital Micro Probe to help inform my management stratergy.

Results show no decay @ upper root and lower stem level.

Will proscribe a 15 - 20% reduction to help aleviate the over balanced lean, plus annual monitor & decay evaluation.

You'd need at least five kids to save shots between these posts

On a serious note, compaction is an issue with kids organised footy in this particular park. so to this end we're carrying out a mulching program, if only to get the kids to congregate pre game elsewhere.

You can see the leaning Red Oak I Dmp'd, to the lhs of the last picture
