Picus Comparison Photos

[Steve Bullman]

Carried out a Picus test on this Beech tree a few months back, then got the job of dismantling it with a crane (video to follow). Tree had both Ganoderma and Kretzschmaria. Have to assume that the majority of the decay shown in the Picus and the felled stem is likely from the Ganoderma. Always a relief when the Picus image matches what you see following the fell of a condemned tree.

Is that 'ring' on the same plane as the actual test Steve?

Or a foot or two lower than where the sensors were placed?

That would be more or less where the picus was taken. Cut the toes off for the fell though which is probably throwing you off

I'm just a bit thick today 

 

As an aside and not wanting to derail...

I had a beech a yr or two back with KD. If it went it was either going into a lake or through a 3m drystone wall/ ancient lake pumphouse and across a little used B road. 

I proposed a picus to establish the extent of decay, contacted a very known consultancy firm whose attitude was don't bother testing! KD + Beech + FELL! 

 

Client never came back to me and AFAIK it's still standing. It would have been nice to have tested it then and maybe monitorred it's progression. (crown wasn't indicating any loss of hydraulic functionality at the time)

Apparently its arguable how well a Picus will actually measure Kretzschmaria anyway

Hi Steve,

 

That's a great set of images showing how good the Picus is. Great being able to compare the two.
