1. Figures
are given in oven-dry tonnes.
Woodfuel will never be delivered at this moisture content. Typical moisture
contents will vary from 50-60% (measured on a fresh weight basis) for
harvesting brash to 25-30% for conditioned woodchips.
2. ‘Forecast’
figures are estimates of the annual
sustainable production that can be made available taking account of
technical and environmental constraints. They do not take account of economic
or market constraints.
3. ‘Forecast’
tables of material from traditional forests:
i) It is unlikely that energy-end markets
will be sufficiently profitable to allow
stemwood greater than 14cm diameter and of good form to be diverted from
their existing
markets of sawn timber to new energy markets.
ii)
Figures for stemwood greater than 7cm
top diameter may differ from the standard production forecasts. An explanation
of any differences compared to the standard production forecast of stem volume
for the Forest Enterprise estate given in Appendix 6 Final Report
B/W3/00787/REP, URN 03/1436. The Private Sector Forecasting Model is described
in Appendix 7.
4. Sawmill
conversion product: figures do not
include products created during either conversion of imported round wood or
resizing of imported sawn timber. These can be a significant resource in
particular locations.
5. Private
woodland: figures do not include
production from woodlands <2ha in area. These can be a significant
resource in particular locations, e.g.
