Stands that contain pine and spruce are common throughout the territory of Ukraine. Investigation of the patterns of growth of modal tree stands requires a detailed study of their existing condition. Based on the stand-wise database of PA “Ukrderzhlisproekt” (as of 01.01.2011) we have analyzed distribution, current state and detailed mensurational characteristics of pine and spruce stands that grow in Ukraine. Their main average tax rates were calculated and a detailed analysis of growth in terms of origin, types of forest condition, age structure, site index classes and relative completeness was conducted. The results have shown that stands with the participation of pine are mainly artificial origin, but the trees with the participation of spruce, both artificial and natural origin are distributed evenly. The age structure for stands both tree speacies is uneven and is characterized by a significant part of middle-aged stands. The productivity of stands is quite high, for pine stands the maximum value of the growing stock per hectare is 820 m³, for spruce stands - 1100 m³.
