Best ways to measure broadleaved woods for firewood

[AlexB]

As said, choose plot size according to stocking density/estimate trees perHA. In that plot (circular) count all trees of every species. Take DBH and top height of the recommend fraction for that sized sample plot. Mark all trees in plots inc a DBH/TH For sample trees so purchaser is able to check the plots for themselves. Then take all the info from all the plots. Get an average. Times that upto your site area. Then take off 10% and bobs your mothers brother. Don't forget to be atleast 5m from the edge of the stand if you can. If it crosses paths/rides knock of another 10% unless you can work out their area and remove that.

I got a copy of the new edition of TIMBER MEASUREMENT.

 

It offers a simple procedure to estimate the volume of a stand from basal area and form height. It says that '[T]his method should be sued when an estimate of total volume alone is sufficient, when doing an inventory, or for stands of low value.'

 

Would this be good enough for measuring a stand of fairly crappy sycamore and ash, or would an abbreviated tariff be much more accurate?

 

An abbreviated tariff may be beyond my competence. I feel confident about doing the volume estimation using basal area and form height.

 

Do you think the basal area/form height method would be pretty satisfactory for an estimate of standing timber for sale as firewood?
