The article presents the results of studies on the growth and development of six introduced coniferous tree species of the family Pinaceae in the Turkestan Range. All coniferous trees in the Kulsay area were planted at a spacing of 3 × 2 m over an area of 4 ha, including Scots pine – 0.24 ha, Crimean pine – 0.54 ha, Norway spruce – 0.42 ha, Schrenk spruce – 1.26 ha, Siberian fir – 0.12 ha, and Siberian larch – 1.42 ha. Tree height was 18.6±0.26 m in Scots pine and 17.8±0.24 m in Crimean pine. Norway spruce reached 18.6±0.23 m, Schrenk spruce – 18.2±0.24 m, Siberian fir – 18.8±0.3 m, and Siberian larch – 16.6±0.24 m. It was noted that the growth and development parameters of the coniferous species under the conditions of the Turkestan Mountain Range were lower than those in their natural distribution areas.
