1. Cost-effective cultivation of lodgepole pine for biorefinery applications
Abstract : The overall objective was to evaluate the scope for the cost-effective cultivation of lodgepole pine (Pinus contorta, PC) stands in a way that would enable early biomass harvesting to supply raw material for biorefineries. Commercial direct seeded PC stands were shown to produce 200 m3/ha of stemwood or 100 tons of d.w. READ MORE

4. Silvicultural regimes and early biomass thinning in young, dense pine stands
Abstract : The aim of this work was to determine how early management activities in young, dense pine forests affect tree and stand characteristics and profitability and to assess the future potential for tree biomass harvesting and use. In this respect, the long-term effects of corridor pre-commercial thinning (PCT) and thinning on growth and yield were investigated in 11 Scots pine (Pinus sylvestris L. READ MORE
