Abstract

The aim of the project was to develop appropriate silvicultural systems for growing forest biomass for energy on short rotation. Species selection, yields, use of herbicides and fertilisers, nutrient removals, management structure and environmental impact were all considered. The project involved :- monitoring existing trials of single stem energy plantations and coppice energy plantations; establishment and weed control of willow and poplar coppice energy plantations; establishment and monitoring of large scale trials of coppice energy plantations; examination of the feasibility of integrating farming with forestry for energy; examination of the potential of agroforestry systems for food and fuel production, and the environmental impact of energy forestry. The work demonstrated that productivities of over 10 dt/ha/yr are attainable with coppiced willows and poplars grown at a spacing of 1 x 1m on agricultural land. Establishment and management of plantations has to be intense and complete weed control is absolutely essential. The environmental impacts of short rotation energy forestry can be minimised and, where arable land is planted, the effects could be beneficial. Economic analysis of coppice energy plantations indicates that if poplars (16 dt/ha/yr) and willows (10 dt/ha/yr) are grown, with the farmer supplying all the labour, the current industrial energy market can be supplied profitably.
