Are coppicing and pollarding used at all to produce timber? I had the impression that it was done only to make firewood, and was cut repeatedly without letting it grow like described in the article.
With a few narrow exceptions most timber crops in the the UK are monocultures or very limited mixes of pines/spruces/firs which outside of nesting season support very limited ecosystem. Even then the management plan for the site would have to account for species present and respond accordingly. Badgers? 20m no go zone from their sett and it may involve another license from Natural England.
I tend to operate at the border of woodland management and forestry. Coppicing typically tends to fall into the woodland management category due to the smaller scale nature of it, especially for when it is for "green woodworking" or craft use. The larger scale biomass coppice sites are very firmly in the forestry size, but still retain the ecological benefits to an extent.
