The seeds were never really meant for fire wood for me, but was interested in adding new species to my forrest, possibly for my kids or indeed grand children, we have oak, ash birch beech and sycamore alreay prevalant, with a mixture of others scattered.
the conversation was started when I meantioned in some other thread that in the UK it had been a terrible year for acorns... guess it went from there.
There is enough blow downs and dead to keep me going for the next 3-5 years depending on my usage, however that remains to be seen, new boiler system fitted last august and still finding my feet with it.
For those that are interested I have started my firewood coppice, 100 williow hybrid sets have been planted, these will be cut back winter 2015/16 and the stems used to increase the coppice size to say 5-6 hundred trees. these are then harvested on a rotation over a 5 year period, i.e 1/5 every year, until after year 5 you are harvesting 5 year old timber which should be circa 6" dia. This of course will not be enough but will suppliment the wood from the forrest, and is totally sustainable. google SRC willow.
FYI
I could get all the species Zogger was so kind to post in the uk,

Anyway will ponder on how I take this forward and will speak to some of the guys at work, who are parks and grounds officers for the local authority and contact my local forrestry commision officer. but some good points on bio-divestity.
will keep all posted on how this goes.
