The present paper is based on a data set of more than 100-year-old cultivation of introduced pines at Jaervselja. The aim of the paper is to estimate the growth and yield of different introduced pine species in the conditions of the Eastern Estonia. The results of the investigations show that Pinus contorta grows relatively well in sandy soils, its productivity is similar to Scots pine which is aboriginal pine species in Estonia. Pinus strobus has a good growth, but the tree is very sensitive to fungal disease Cronartium ribicola. Pinus banksiana grows relatively quickly at the young age, but its timber quality is very low. The productivity of introduced pines is mostly lower than of the Scots pine. The introduced pine species have importance mainly in park management
