Hi Rupert

Unfortunately no figure for Oak, I'm afraid. I thought estimating on similar 
lines to Ash wouldn't be unreasonable, in the absence of any more specific 
references/research info. 
So many variables, and a pity no-one actually hangs around long enough to 
measure the diameter of coppice stools every 100 years. Tsk.

All the best

Hi Mark,
We have a lot of oak coppice down here - used for the tanbark& charcoal 
markets in later years; and earlier on for smallwood,  and intermediates in 
between the main frames in timber-frame construction - lot of old 
timber-framed houses even in areas with good stone. 
Do you have a figure/approximation for oak?  I imagine slower than Ash Atb

Hi Dave

I did a bit of work on this a few years back - collating various sources 
(Rackham, Colebourn, White & others), one can derive a very approximate 
estimate of 0.45m-0.5m per 100 years for Ash, and 0.6m-0.7m per 100 years for 
faster growing species (Sweet Chestnut, Elm).
Very rough of course, and subject to all sorts of variables (site conditions, 
rotation length, stocking density, cutting height, whether internal in cant 
or on the edge, etc. etc.). I would suggest measuring a random sample of 
about 50, scattered through a compartment/coupe/cant, and taking an average.

All the best

 Sounds like Oliver Rackham? Trees and Woodlands in the British Landscape has 
some useful points on coppice ageing, although I don't remember it mentioning 
exactly that rate of growth.

    Hello all,

    I'm trying to age an old coppice tree and am finding it surprisingly hard 
to find much data from Forestry Commission, Ancient Tree Forum or academic 
papers.

    I've got an unsubstantiated amount of 0.3 m diameter/ 100 years measured 
at base, but can't find where that has come from.

    I'm surprised that the ATF seems fairly ambivalent to coppice trees as 
surely these trees are likely to be oldest and commonly found. Fair enough, 
they don't look as impressive, but that can't be a reasonable reason to give 
them so little attention.

    Anyway, if there is anywhere you can guide me, I'd be most grateful.

    Cheers

    Dave
