tonnes per acre

[borderfirewood]

I have 16 acres I am thinking of planting with Silver Birch and Ash, what size would they be in about 20 years, also how many tonnes per acre would I expect to have then???? Thanks for looking

Have a google for "yield class". It gives typical volumes of timber that is produced per hectare per year.

 

Be aware that "yield classes" are normally calculated over a longer time frame than 20 years - obviously young trees will have a lower growth increment than older trees.

Not sure I would be planting ash if you want it there in 20yrs,

 

16acres = 6.6ha

 

6.6ha @ Y.C6 = 39.6tons per year

39.6t x 20yrs = 792tons total volume (this will be an over estimation as you will have failures and a lot of timber by year 20 will still be unusable as firewood)

 

792t / 16acres = 49.5t/acre

Ive read a coppice can produce 3.6cbm per acre per year. Not sure whether that helps mind.

Plant a sweet chestnut coppice interspersed with oak to grow as standards and draw successive crops of chestnut up straight

Fencing/garden furniture making material or stove firewood.

Suss your soil type out first ash (if you didn't have to worry dieback), birch n oak will grow well pretty much anywhere, but chestnut and some others may not fare so well on the wrong soil.

Thanks everyone for your reply's

what soil does chestnut grow on
