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.
woodland: figures do not include
production from woodlands <2ha in area. These can be a significant
resource in particular locations, e.g.
