Biomass from forestry

I was member of the discussion panel in Vakblad Natuur Bos Landschap of Februari 2011 (pp 8-9), as it went about sustainability of biomass from forests. Is it in contradiction with dead wood and biodiversity creation? My reaction is to be summarized as: I can imagine the fear for taking too much biomass from the forest soil. But it clearly depents on the type (fertileness) and development stadium of the soil. It does not look like biomass yield in forestry in the Netherlands has increased much. Forest owners should look at it as an investment in the quality of their stands (logistics, species mix) and timber; it's a way to manage young forests with more benefits!
