Stage 3 of heavy retrenchment of this massive Oak, we were encouraged to rip and fracture branches as we cut so the westtech was the perfect quick safe option.
Tree's still 22-24m tall for scale and we removed at a educated guess 5ton off it this time.

When you say stage three what were 1 & 2? 
Were they done over the years or recently? Is the tree compromised in some way?

 

I may have missed the story in earlier posts, if so sorry.

 

TIA.

Retrenchment is a staged crown reduction over around 20 years to try a force the tree to put on a sub canopy mimicking the natural stag heading of ancient oak's.
This tree was started 10 years ago with a reduction of overextended laterals then 5 years ago we did a 4m reduction of the whole canopy then again a 4-5 m reduction.
The trunk of this tree is heavily compromised by 3 active fungal infections that have been clearly identified but the tree is of such historical significance removal wasn't consider as a option nor was it nesisury immediately so working with a very good consultant and the arboretum staff this was felt to be the best long term management strategie.
After the first reduction we didn't see much reaction from the tree but after the second the response was amazing and the flush of leaf had never looked so good for years so hopefully with how we managed to remove so much material without damaging any of the inner canopy will again force the tree to put energy into developing this.
