Bit of an odd day today, real mixed bag, but variety is good.....thought I'd post these pics of Tim doing hat is probably the only retrenchment pruning to be done in NQ ever! (Well deliberately with both intention and understanding anyway)
These are mangos in the soon to be sold Defence grounds Jezzine Barracks Townsville, suspect they are around 100yrs old...we're doing an cyclic program of tree works for Defence and mitigating the risk from dead and decaying parts of these two trees (along with others) is part of that.
So some shots of the before during and after with Tim doing all the cutting, well the camera is heavy you know!
But its what was around the stem that caught my eye, now remember I think the tree is around 100yrs old, I also think I know what is going on here I've seen it before in a number of trees in different places....No its not the old big branch injury that hasn't closed though that has resulted in an interesting hollow that extends right up through the tree, its the loss of tissue functionality around almost 60% of the stem..look at the adventitious roots growing out of the bark tissues.
Now obviously its damage, but from what impact of line trimmers? well a possibility but unlikely to create what I can see in the bark tissues, a long spiral like wound travelling almost all the way round the stem circumference...I'll play with MS paint and show you what I see.
