Existing sources are unlikely to meet future
demand for woodfuel. So, new sustainable wood fuel sources are
needed to fill the gap. Short rotation crops are one option being
investigated.
Growing wood fuel-specific crops by short rotation
coppice or short rotation forestry has
the potential to meet the demand but we need to know more about how
these techniques would fare in Scotland.
Forestry Commission Scotland and Forest Research are
establishing country-wide energy forestry exemplar
trials which will provide us with that information.
They will establish the potential of short rotation crops for wood
fuel production and will serve as demonstrational and educational
resources.
Short rotation forestry
This is when single stemmed trees of fast-growing species are
grown on a reduced cycle (10 to 20 years), primarily for the
production of biomass.
Short rotation forestry involves more time investment but also
has the potential to be grown on as a timber crop, rather than as
biomass, should the market dictate that this is a better
option.
Because short rotation forestry can make use of more marginal
agricultural land to produce a higher energy, higher quality
product, it is seen as being the option that is best suited to
Scotland's growing conditions.
Short rotation coppice
Short rotation coppice is woody vegetation grown on a repeated
coppice cycle of 3-4 years specifically for the production of
biomass. It has not been widely planted in Scotland since it
requires high quality, arable land for good growth but produces a
lower quality crop.
