Retrenchment pruning

[One Buck]

Hello chaps,

Could you please direct me in the direction of some decent up to date reading regarding retrenchment pruning.

The trees the I am considering are three very large Beech, close to a high value target. One of these has major decay in the stem base (up to 3m), the second (my hammer suggests) has a decayed buttress root (likely caused by the construction of the 'target') with a probable decay column above, and the third has a lovely bloom of meripilus going on ..

Normally not knowing the reliability of people to carry out long term and detailed recommendations, I would recommend either felling or 'monolithing' .

Unusually, in this case there is a budget and a reliable manager.

Admittedly, both my knowledge of proper retrenchment, and my ability to communicate it accurately in my recommendations are a tad rusty.

Any suggestions would be appreciated.

Thank you ..

Thanks David,

I have the Lonsdale book. The rest of the evening will be spent with the other suggested reading.

Much appreciated ..

Also check out page 122 onwards of the new book 'Trees, a Lifespan Approach' co-authored by Nev Fay.

 

Expands on the retrenchment paper (above) a little more.

Once again, thank you kindly.

Its nice (and rare in my experience) to find somebody who is both prepared to accept the (considered) risk, and commit some resources to a longer term management plan.

Quite looking forward to this one.

Read that and rather disappointed on the lack of detailed guidance. You'd get much more from David's thread here about Dealing with Damage and Dysfunction".
