Tree condition of Abies, Picea, Pinus and Pseudotsuga genera was studied in the forests of six forest enterprises and twelve forest districts in the south-western and western Lithuania in 2003–2007. According to our studies, the most perspective species for growing in these parts of Lithuania could be considered Pinus contorta and Pseudotsuga menziesii. Acclimatization success of other tree species: Abies alba, A. sibirica, A. concolor; Pinus banksiana, P. peuce, P. strobus; Picea glauca, P. pungens; Pseudotsuga caesia – is restricted by biotic (disease pathogens and pests) and abiotic (edaphic and climatic conditions) factors.
