Girdled roots

[Gary Prentice]

Would perhaps hide an eyesore, but not entirely sure it would do much else?

 

Might cut back the left hand side of the bark to where its not loose to enable & promote callous regrowth

Been keeping an eye on this old horse chestnut and its associated decay 'issue' for a few years.

 

But its interesting to note that due to being overtly fung-centric my focus has not lingered on the obvious girdle at the site of the lhs Rigidoporus fruit body

Slow dessication, and all the other D's that follow.

Enable interior parenchyma cells to generate new cambium--faster sealing.

Not much loose to trim by the looks of it but ok.

 

Far more important to Find the Flare!

The above has got me to thinking & reviewing previous (ongoing) cases

 

Shots of a reduced beech (from 5 years back) which has Meripilus.

 

First noted the fruiting on this tree about 10 years ago.

Its still fruiting each year & continues to be a viable retention, imo.

The 'air'cavation uncovered a number of partialy grafted and ungrafted girdles & evidence that the decay was mostly concerned with the older lower root system.

 

The girdles will undoubtedly be having an effect on the vascular flow, root vitality & the trees ongoing battle to regenerate new roots to keep the balance of new (over) & old (under) tree, optimal.

I guess its no real suprise that when you start looking with connective glasses on, girdles, dysfunction & decay are often heavily associated.

Gorgeous documentation thanks

 

What we need are connective glasses with fungicentric and vta lenses

Yes Johnson and Hauer did good documentration there, but being university guys they left it to others to describe practical solutions. Hauer and others were later questioning the practice of ungirdling buttress roots. The consensus seems to be that if stem tissue is not girdled then retention should be considered. On your beech

it's a tough call. The tendency would be to favor those pathways that seem to contribute the most to codit. Where guesswork seems to be more in play than decisions based on evidence, then doing nothing is one policy.

But ungirdling everything that is not grafted does save the tree energy, and striving for that old-new balance seems quite reasonable. It depends...
