Dual Decay

[David Humphries]

A client's tree Dave...........

 

.........Would like to reduce and retain if possible.

 

 

 

Surprising the white rot of the resinaceum didn't show much of a presence with the resistograph. Perhaps as its fruiting from a sinus its not yet into the sapwood regions?

 

Tree 'looks' vital enough to take a relatively hard reduction though ?

 

Multiple readings taken?

 

Any other fruiting on the side out of view?

 

 

Clients give any indication of how long the resinaceum has been fruiting?

 

Lots of questions interesting situation

I've been mulling on this one today after looking closely at the resistograph readings. I took three readings - all at about 20cm above ground level: one between the Gano and the 4 Inonotus brackets, one between the main Inonotus brackets and another a third of the way round the stem, and a final reading from the opposite side of the first.

 

The first two readings were pretty flat - not the steady incline you'd expect to see in sound wood. Looking closely at the trace, there is also less 'flicker' in the reading than normal - the minor variation in resistance that you see as the bit passes through annual rings.

 

The third reading was much better as expected being farthest away from the brackets.

 

Although I think the tree could take a reduction to reduce the windsail I believe this would only be a short term measure - and one which would need repeating which will inevitably reduce the amenity of the tree. I guess I'm also aware of the client's purse strings...

 

The tree is on a corner of a road junction as well as within 10 metres of the flats and their parking spaces. Without further investigation of the roots I'm not confident enough to retain this one so reluctantly I've recommended removal. No doubt others will disagree!

[David Humphries]

The removal looks a fair call Paul, certainly with regards to the ongoing monitoring and the potential for numerous return works.

 

Out of an interest of looking at this tree in its setting,

 

does it appear to be a lone oak or from a large (but seperatated) population?

 

What's the story/history of the estate developement?

What will be interesting is to see a photo of the crossection to see how the two fungi have walled each other off.

Agreed. I'll try and find out who the contractor is and request some pics or notice so I can be on site to have a peek.

Two different pedunculate oaks from today at a National Trust site.

 

1st - merip & fistulina present

 

2nd - laeti & gano (possibly resi but not sure)

[sloth]

That's a hefty fisti, nice one. You sure that's gano with the chicken though?

[RobArb]

Not sure what else it could be?

[sloth]

Neither am I! Just doesn't look quite right for gano, too pale, odd shape for resi, no brown spores showing. Closest I can think of is oak poly, but that's not right either. Maybe it is just a gano

[RobArb]

I know (or more, i reckon), it's a old slug/insect eaten Inonotus dryadeus
