Estimating quantity's of standing wood.

[Woodworks]

I got asked to come and quote on a small job locally.

 

What I thought was going to be cutting a couple of over hanging trees down and some brush-cutting turned into part clearing a small area of woodland. The area is nearly a 1km long by about 25m with good access. I would not normally not look to do work like this but the customer is happy for me to take wood in payment and our firewood business could do with this timber. I am intending to go back and take a second look and measure things up. How do I go about estimating how much standing timber there is there? It's mainly ash and alder if that helps. Any guidance welcome

Who is responsible for a felling license, client or cutter?

Had a quick google. Does this equation look OK for a rough estimate?

 

 

In the absence of local equations, cubic volume of wood for standing trees may be estimated by the following equation:

 

V = 0.42 x B x H

 

where B is tree basal area at breast height and H is tree merchantable height.

Unbelievable; standing timber for free! You are the luckiest man alive; ash and alder would normally sell for standing at over £20/m/t now...

 

Is it a uniform crop? Work out how many sticks you've got in the area, then the average dbh and height and I'll work it out...

Thanks for the offer TCD

You could well be right about being lucky on this one but I have got to fill his large shed with logs and leave things really tidy more like a drive than a woodland so a fair bit more work than just cutting and clearing but could well be worth doing whole job for nothing. I need to get a good handle on how much wood there is there before giving a price or not.

 

Going to sound foolish here but what is a m/t and dbh ?

metreage / tonnage and diameter at breast height...

Been back today and had a measure of some of the trees (ash and alder). Circumferences go from 60cm to 120cm. Height of main trunk until approximately 10-15cm diameter 12-14 meters. I have counted trees in measured areas and grouped them into circumferences going up by 10cm increments. I have had a crack at working out the volumes but would be interesting to see what you make it before I own up to my efforts

so between 20 and 60 cm diameter? Has to be diameter...

20cm to 40 cm in 3-4 cm increments.
