mensuration question

[Dean O]

say I have a European larch with a dbh of 60cm and a top height of 28 metres - from which Ive gathered a tariff number of 33

 

how do I calculate volume on a single tree - Im sure I remember calculating the volume of the cylinder and then multiplying this by a predetermined figure to compensate for the taper ?

[Dean O]

sorry - should have said - Ive worked out as the volume of a cone this comes back as 2.64 cubic metres per tree - but this seems way off what I would have 'guessed' at...

 

I'm needing to slowly take out some larch which have at some point worked their way into a small woodland but are now not wanted - I just want to make sure that I don't go over the felling licence per quarter figures.

 

thanks

Well that tariff number and diameter give a volume of 2.89 from the tables in blue book but I suppose you used the blue book to derive the tariff?

[Dean O]

ah thank you

yes - but what page did you get that from please as I couldn't find it this morn.

Mensuration?

Thats women's stuff, better off keeping out of that:biggrin:

Tariff Tables are right at the back in front of the index in my 1975 edition

If you are going to sell the timber, you can only fell 2 cube per quarter, so you will have to fell them at head height.

Is that seriously a legitimate way to get round it?

thought i miss read that @ 1st

No not at all - you shouldn't be using a saw above shoulder height.

 

I'll probably spike up six foot or so and 'av er out there' to make certain.

 

But seriously - the client has other work to be carried out on the site, pruning trees around the house, and when she had asked me about her plans to get rid of the larch I'd suggested the need for felling licences could crop up - they are big hairy blighters but will be felled to waste/ perhaps branch wood chipped back into the woodland.

 

I've also suggested leaving the odd mono.
