Lightning damage & Fungi

Recommended Posts

Haven't noticed any fungal activity on either of the two above as yet, perhaps worth a look later in the year.

 

What is of interest is why the path of the strike took to one side of the callousing wound & not the other?

 

Shortest path (least resistance type gig) or a difference in wood fibres either side of the collar due to angle of the cut :hmmmm:

reckon your right with least resistance, the lay of the fibers is evident:thumbup1:

Ash with occluding lightning strike (not sure when this event was)

 

Ganoderma resinaceum at the base fruiting between butresses.

 

May put the resistograph on it.

 

Tree will be reduced (fairly heavily)

pretty colored fung. would be keen to see what the resi shows; maybe not much if the strike is not old. cracks are sometimes seen better with resi than tomo...

 

where cracks are the features of greatest concern, perhaps a rough pull test from different angles, whilst observing movement in the crack up close? just a thot--fraxinus are quick to split ime, if unpruned that is.

Decent sized Wellingtonia at Wimpole Hall with what I imagine is an old lightning strike.

 

No fung but some bug activity in the exposed wood.

Wellingtonia

 

No idea, was just visiting today.

You'd have to ask the National trust :biggrin:

 

Looks to be doing just fine by itself

back at Wimpole today for a walk around the grounds.

 

this oak is a tall feller, no scale alas, but perhaps 25m

 

 

seems that the tall trees on this site (like the wellingtonia above) are subject to a high risk of strike.
