Managing Trees with Decay & Dysfunction

[Gary Prentice]

Its always a difficult decision, for me, reduce end weight or keep foliage to produce energy for the creation of reaction wood and defence. Delicate balance.

 

Not being critical at all, just commenting, but that failed limb didn't appear to have much in the way of foliage along a good proportion of its length. I don't know, however, if that's a common growth habit of the species.

Good point, I watched it again to see if the failed branch appeared to have more or less foliage than the others but I found it difficult to see.

 

What did strike me on second watch though, was that there appeared to have been pebbles laid in around the stem. Didn't notice that first time.

Heavily leaning oak that looked to be subsiding toward the target of a cycle track & an A road.

 

The canopy showed a noticeable gap away from its neighbouring trees.

 

There was a basal wound on the side but appeared solid via testing with a sounding hammer and looked to be just bark and cambial damage.

 

We decided to go grab the small mewp rather than climb-dismantle as it couldn't be straight felled.

........There was a basal wound on the side but appeared solid via testing with a sounding hammer and looked to be just bark and cambial damage.

 

this became more evident when cross sectioned

 

we also took clinometer readings before & during the dismantle to keep an eye on the lean and to see if it changed when the canopy was removed.

 

Whether the 1% reduction in lean was due to the above or variations in the reading....that's something for the technocrats can debate.

 

the lean certainly looked a lot stronger than when we last inspected this stretch of road a few months ago. was a keen spot by a colleague that alerted us to it.

Great thread the information is great I'm just really starting to get into my inspection and management of trees and this is really helpfull cheers

Thanks, glad you got something from it.

 

It's fundamental to share experience, i continue to learn so much from people who share theirs.

Of topic I know but what speed is the road? I'm surprised nothing is being done to control the traffic. You did well to get it down.

It's a B-road in the London Borough of Camden

 

This one is a 30mph limit

 

The control in place were a site specific risk assessment, tree work signs, cutting during gaps in the traffic flow & 2 on the ground managing pedestrians and cyclists.

Also holding sections with a strop where required.

I see, very good. Off topic questions over 😃
