Returning for a sec to the issue of forks and inclusions, the attached image is of a 30m Lime that failed at 4m, shedding a 26m limb (I can do maths, me) on to someone's forest lodge (fortunately unoccupied). Annoyingly I only have this image left!

 

This is the first time I saw the tree - apparently someone had appraised it a few years previously (...). Incidentally the shed limb also wiped out a 15m beech and half a reasonably sized oak. The stem is pretty much shot up to 4/5m with extensive white-rot extending into the failed stem (G. australe). There was only approximately 3 inches of uncompromised wood by which the limb was attached and this tree failed on a perfectly calm day!

 

There were loads of other mature/over-mature limes at this spot with interesting features for which I have temporarily mislaid the images. I may post these if and when I find them.

 

Great thread by the way, having worked with trees for a number of years I have come to appreciate the infinite variety they represent and realised I have will always have much to learn!

Just how many years previous did the appraisal get done?

 

Ganoderma australe could more than likely not even fruited yet in such a scenario, so would be difficult to say the appraisal was bad, unless there was a perenial bracket with its annual layers available for the count.

 

G. australe can be a difficult one to detect sometimes all thats there (like Kretzschmaria deusta) is a small hard blackened bulb low at the butress bases.

 

Given the low level of info avaliable on G. australe, and the none existent understanding of panic fruiting as described by Gerrit Keizer its no surprise such a tree was under evaluated.

Was that meant for the fallen ash thread? :)
