Abstract: The density is easily determined and controlled effectively as the original stands breeding and conservation rate. A comprehensive and objective assessment of the initial density may greatly increase the plantation sustainability, productivity. The first test in Lithuania of different initial density Scots pine seedlings were planted 1960 in Dubrava district by M.Daujotas and A.Kirklys. Later, there was planted a number of various different initial density plantations. Now trees are 17 years of age. They began intraspecific competition between individuals (trees), their differentiation parameters (height, diameter, etc.). The maximum mean diameter (6.92 cm) was established in lowest density (2100 units/ha) in variant 17b. The biggest young pine average height (4,6 m) was established in average density (6000 and 4615 units/ha) variants. In all vairants and their reps timber volume ranges from 13,7 to 64,9 m3/ha. Some reject the options that are extreme, since all other options are different in characteristics, volume ranges from 22 to 58,2 m3/ha. It was found that all variants are in good condition, both in terms of potential insect damage as well as damage by wild animals. It is likely that we can plant Scots pine seedlings in lower density (~4500 units/ha), than it is provided in Lithuanian regulations (5000 units/ha)
