Hello, I work for a large national charity which owns a large woodland and the comments recently about burning dead wood is yes worrying but there are other forms of biomass which are less damaging. Also burning the dead and dry wood is perhaps not very effecient becuase it has to use a techincal phrase low calorific value which in laymans terms means that it wont produce much heat for the amount wood burnt. Other timber crops if seasoned like Sweet Chestnut, Hornbeam and Oak have higher calorfic values so produce more heat for the amount wood burnt. In our large woodland we are restarting the coppicing cycle on our 300 + acre Sweet Chestnut coupes for biodiversity but the byproduct it will heat a small biomass boiler to heat a number homes. The main parts of the trunk will be used for fencing and other woodland products and the smaller and less straight parts of the trunk will be stacked and when they reach around 15% moisture content they will be chiped up and put into the boiler. We have worked out the whole process will be 95% carbon neutral we gained an extra percent or two becuase we are doing everything in such a small area. Its is believed if the whole of the area of sweet chestnut woodland in Kent and Sussex went into this kind of cycle and managed properly it could supply the whole of the areas need for heating sustanably and for the future. I believe our woodlands are changing too but increasing the areas to forestry is possible. Its one of those ideas that is good but then again could be bad because the areas must selected for the right reasons so damage to important habitats must be mitgated against which I believe they would be. The currently woodland cover is believed to about the same as it was when the Romans occupied Britian. So do we need more trees and is there a potenial for conflict? The goverment wants us to build more homes were are going to put in the infrastructure to cope with this increase? Is there enough space? These are the questions that need to be asked and answered before the trees are plant .
