Effect of logging residue removal and mechanical site preparation on productivity of the subsequent Scots pine (Pinus sylvestris L.) stands

Abstract Key message Removal of logging residue negatively affected tree diameter and height, but had no significant effect on the basal area subsequent stand (in mid-term). On other hand, different methods mechanical site preparation (bedding, plowing furrows, trenching) growth 1 year after planting, a diameter, in mid-term. Bedding treatments could have positive impact productivity Scots pine stands, even when planted sandy, free-draining soils. Context Increased use residues forests may address growing demand for renewable energy. However, concerns arisen regarding depletion forest soil, resulting decrease next generation. Identifying drivers be key to understanding relationship between removal productivity. Aims Quantifying three combined with five management (complete removal, comminution, incineration, leaving whole, comminution with, without mixing topsoil) 12 years planting. Methods The experiment was set up as randomized complete block design 45 plots replications combinations treatment methods. Results effects were not planting bedding caused increase DBH, years. Various did cause any differences survival rate nor next-generation stands; however, there influence sizes. Moreover, changed time; residues, trees highest years, their height DBH lowest. Conclusions It can concluded that stands. No found stands further confirms increased biomass from environment does necessarily result its rapid degradation. Observations at longer term are however needed obtain full spectrum responses removal.
