Interesting Biomechanics

Dunno if this counts for this section of the site.

I don't suppose that is on one of the canary islands is it?

Here is a few more interesting trees off the camp I work at.

Costa Teguise, Lanzarote.

Costa Teguise, Lanzarote.

The crushed lava rock gave it away. We have been to tenerife every year for the last 7 years. I was looking at these trees too they are peculiar no idea what they are though.

Some of the roots look rather phallic [emoji16]

They look like Chi Chi's, aerial roots sometimes found on stressed Ginko 

 

Pretty cool

Inosculated aerial roots on this Arizona ash, Fraxinus velutina var loumeyi at Kew Gardens.

 

Couple of images taken 5 years apart.

 

First one was taken in May 2012 and the second image taken today by Ted Green.

 

 

Some secondary growth thickening in evidence but not as much as one would expect, even the wound wood on the pruning wound is relatively limited in terms of occlusion.

 

Perhaps a good mulching to improve the rooting environment and keep those over enthusiastic snappers a bit further away

Are the aerial roots common with that variety of ash David?

[David Humphries]

No idea, never been to Arizona, think I'm probably banned from the State 

 

I have seen our native ash and other species do this though, expect it was initiated by a mechanical wound earlier in its life where cell division at the callus tissue has formed into roots.

Fine example of aerial rooting on this oak pollard in the Sierra Andia region of the Basque.

 

Can trace the 'roots' from the inside of an old occluding wound at the end of a hollow scaffold, right down to the soil.

One of my favourite things to see on a tree. That’s a beauty.
