Nice catch--great reflexes!

We were in the process of reducing the canopy due the semi-autonomous units of the trunk (thanks for the term Dr Lonsdale ) were starting to open.

 

The twig was in there to monitor the movement of the crack as the various parts of the canopy were dismantled.

 

If the twig dropped out we would know the trunk sections were becoming more unstable as we were working it.

 

As it was, the 15mm gap closed to 8mm by the end of the work.

Old oak on our boundary overhanging a neighbouring garden.

It lost a significant portion of its canopy (in part due to the brown rot of Laetiporus) during last years st judes storm

 

Only just got around to dismantling the hung up section today.

 

We rigged it down between an impact block up on the tree and the Landy winch.

Never seen Laetiporus fruit on this particular tree so hadn't considered it as a significant hazard to the adjacent property.

 

Having now seen the extent of decay in the failed section, the remaining canopy will be reduced to lessen the sail.

I have a number of poplars in similar states to these ones, some worse than others and some with similar wounds higher up in the crown. One has a tear out on opposite sides and now has a gap through the stem. No immediate public risk although there's an informal footpath and a major road near some. I have some down for felling and in a bid to prevent total structural failure of a number of them due to them being P. nigra betufolia I have recommended a plan to reduce them heavily.

Plans for habitat assessment for nesting birds/bat roost potential prior to works Rob?

There's certainly potential for both. Could see any signs of either from my assessments. These trees pose a higher risk to commercial waters than public access so the work isn't urgent. They have been very much left to their own devices till now. Largest one is 1.5m DBH.

 

Will be looking into assessments of any with cavities at altitude.

On the oak, looks like a very old wound at and above the 'crook' where it failed. (very nice of the tree to fail away from the buildings) Lack of tree response = good idea to reduce.

 

On the poplar, despite species reputation, there looks to be a very good response by the tree = less need to reduce?
