 The main competitors yield wise is willow and poplar, grown at short rotation coppice (SRC) or short rotation forestry (SRF) plantations.In the northern parts of Europe, willow and poplar approach and sometimes exceed miscanthus winter yields in the same location.FAO (Food and Agriculture Organization of the United Nations) estimate that forest yields range from 1 to 25 m3 "green" (non-dried) wood per hectare per year globally, equivalent to 0.4–9.3 dry tonnes per hectare per year.
