help with damage to limes.

[peter barnes]

surveying limes today and 4 appear to have significant damage through to heartwood, I've not seen this ´before so need help, as all are protected but display severe dead wood and die back and NEED to justify reason for felling.

cheer guys.

Looks like 'target canker' any wider context shots?

NO reason for felling

[peter barnes]

sorry no other shots dave,

why would you not fell tony?

The tree´s are in an alley positioned in a church yard where the public are, thought it would be safer due to the depth (about halve way through the trunk)

There is no evidence imperical or otherwise to suggest cankers are a weak point.

 

mattheck weakened trees with notches for his T/r theory work and those with cankers did not fail at the cankers.

 

you would have no grounds to justify felling on a canker alone

[peter barnes]

cheer's tony, will have another look later and rethink my assessment.

[David Humphries]

In the Forestry commissions guide on Hazards from Trees (2000) David Lonsdale states that wind load on a target canker that has affected up to 25% of the stem circumference of a trunk can cause a snap and should probably be viewed with caution and that reduction or felling should be considered where there is a risk to target particularly where a tree is open to exposure.

 

 

Having said this, I haven't seen an example of a stem target canker having failed.

Have you a link to that Mr H? I'm sure that I've read that but have no recollection of that information .
