"suggesting the UK government target of 1·1 million ha by 2020 is feasible."
The other interesting news from this is that butterflies might do rather well out of Miscanthus and Willow plantations.
Butterfly abundance proved the most appropriate indicator, [of biodiversity] and it was found that total abundance was greater in field margins of both willow and Miscanthus biomass crops than in arable field margins.
Though the abstract didn't talk much about species and seemed to be more interested in the number of butterflies... I think some lepidoptra are quite specialised in terms of habitat and food.
