Table 4 Proportion of sawn wood grades (%) of total harvested volume over the rotation with Policy 0 (conventional harvest), and percentage changes (+/−%) of Policy II (compulsory energy harvest) compared to Policy 0 for five Scots pine stands (initial density 3000 trees∙ha−1), energy wood price 15 €∙m−3, interest rate 3 %
From: An integrated assessment approach to optimal forest bioenergy production for young Scots pine stands
