Ha ha, I like your style! That's more of a light thin though.

[Mr P]

So your saying I should go a bit harder on it next time??...

Nice one:thumbup1:

 

My kind of "reduction", I'm always happiest when the customer gives me a very precise finished hight requirement

You hardly touched it you hippy.

[Mr P]

It was in the middle of summer so I didn't want to kill it!

Actually if that was a reduction it does exceed the bs3998 advised cut diameter, it might be alright actually as its only 1. Not sure you'll have to read up.

Surely 1 big cut better than 50 smaller cuts... well thats my rationale

I've been climbing for 3 years now but it has mostly all been on utility work (until about 4months ago) and due to the nature of the work I never really had to do full prunes or reductions. I've asked this question to a few other climbers but they never really gave me a definitive answer so I was hoping some of you guys with more experience in the field could shed some light on it....

 

whats the difference between a prune and a reduction??....told you it was basic!!

 

I don't mean a reduction in height as thats pretty obvious but one in volume. I've been told a reduction is just a heavier prune???

 

Also I was told over here (Toronto) a prune is crossing branches, dead wood and cleaning out the sprouts in the centre of the tree but you generally don't go out to the ends of the branches at all!! Back in Belfast where I learnt to climb I was told that in pruning you also take off some end weight.

 

Any thoughts or opinions are much appreciated as is piss taking cheers paddy

Pruning is a generic term covering a whole range of tree crown management operations, inc. crown reduction / crown thin / crown lift, as explained in the industry standard BS3998 (2010)

 

The attached seeks to highlight the difference in a crown reduction between a 'volume reduction', BS 3998 indicates 30% volume equiv. to 12% linear, i.e. an average radial spread of 10m will be reduced to just under 9m, and linear / length, i.e. average radial spread of 10m will be reduced to 7m (this exceeds the 'implied' max. of removing more than a third of the foliage bearing material and so if specifying you should state these works exceed BS3998.)

 

Hope this helps...at least a little.
