Picus sonic Tomograph


Xerxses
 Share

Recommended Posts

Here's a quite interesting few photographs for you Xerxses. The tree with the driveway in front was asked to be removed because of the 'lifting' by the roots. So one of the team went out to assess the damage and form a report. Whilst there it was evident that a tree nearby had Phaeolus schweinitzeii FFBs at the base.

 

A PICUS was carried out on the adjacent tree and in the meantime the tree that did NOT have the FFBs was felled. The resulting picture shows the decay found in the 'adjacent' tree which makes me believe that the roots were grafted and connected to the fungi.

 

The PICUS pictures are of the tree with FFBs. I do not have pictures of the felled tree which the PICUS was used :thumbup:

Marco,

Great documentation :thumbup1: . A question though.

Is it in your experience valid to say, that in general tomography of (brown rotted) coniferous trees, like this Pinus, is more reliable and better interpretable than it is of most (brown or white rotted) deciduous trees, because of the differing structures of the wood ?

Hi Gerrit,

 

I will try to do a comparison at work as I have only limited experience of using the PICUS. I will look at some random records of conifer and broadleave tree reports to see if I can spot a trend :001_smile:

:thumbup1:

So you used Picus on one tree with FB on it and felled the other? So picus are from tree still standing and pic of stump is the one witout FB, did I understand you correctly? So no correlation between Picus and stump shot? Except it would look very similar to the one you felled?

Hey. Was wondering what height those tomograms were taken at? 4 on the same tree? Also is that Pinus sylvestris or P. nigra?

 

I've been working with an experienced guy who has his own kit for over a year now, i do most of the contracting these days.

 

Here's a tree i did as a wee project for college: Beech with targets, test at 380mm. Fruiting bodies at base. Ganoderma sp. but not sure which!

 

Picus suggests that wall 4 is intact. This would mean it's the G. sp. that is an intensive heart rotter but aint so great at breaking the barrier zone. Anyone remember the name? Don't have Shwarze to hand.

I assume you mean Ganoderma lipsiense (= G. applanatum), a perennial necrotrophic parasite, that predominantly in beeches causes an intensive white rot with selective delignification of the heart wood.

That's the one, thanks. With a bit more experience i'll remember the difference between G. applanatum and adspersum. G. adspersum the one that munches through wall 4 then i guess.

 

Oh ai, forgot to mention - from that Picus we decided not to fell. If it had shown it to be G. adspersum it would have been game over. Useful data

Did you ascertain the fungal entities purely by compartmentalisation?

 

G. pfeifferi is also a strong likelyhood in your scenario, in fact, given those fruit bodies, their locations and the fact they have not developed a great deal would suggest g. Pfeifferi to me?:confused1:
