Sequoiadendron Gigantum with a crack

[Island Lescure]

Just looking for a bit of advice as usual.

 

As title says except that the crack(?) starts at ground level and goes up around 10 meters where the fissure becomes narrower. It is not clear on the video and I don't know why I didn't take a better pic but at 10 meters, you can see where it is forming two ridges that are not occluding. So there is either movement or the bark is getting in the way.

 

I am wondering if scribing the upper area to incite grafting may be an option to recommend. Does anyone have experience with this on sequoias?

 

What about the inrolling bark near the base? I suspect it would eventually cause a sort of ring shake as it pushes against the dead wood.

 

Otherwise all I can recommend is aerial inspection and possibly Picus up there.

 

Wood at base is sound.

 

Sorry about the sideways pics. No idea why they have gone sideways. They are close ups of the inrolling at the base up to maybe 2 meters.

Hi

sure its not lightening damage?

Hi,

 

No, not sure. But I would expect lightning damage to have singed another branch as well and for the area where the fissure is narrow (higher up) to occlude instead of looking like two branches rubbing together without fusing.

I need to look more into lightning damage...

Not seen a lot myself, but given the size of tree and size of split its possible.

Could be lightning damage, or other mechanical/animal damage in the trees earlier years. Inconsequential I would say.
