The article presents the results of studies of experimental forest crops created by planting seedlings of larch Olginsky, Amursky and Siberian (Larix olgensis A. Henry, L. amurensis Kolesn., L. sibírica Ledeb.) In the south of Primorsky Krai in the late 90s of the 20th century. The paper analyzes the variability of the main taxation characteristics of the established stands according to the following indicators: average height, average diameter, average increase in height and diameter, stock according to the results of two surveys conducted in 2005 and 2020. The safety of plants in the stands, the distribution of trunks along the steps of thickness were studied. According to the results of studies, it was found that the species of “oceanic” origin showed the best growth and productivity indicators: Olginsky larch, Amur larch occupies an intermediate position, and Siberian larch under these conditions does not have a silvicultural potential. The adaptation period of plants of all species was two years; it does not depend on the type of planting material used to create forest crops. It is concluded that it is advisable to create forest crops, forest plantations, including seed ones, from the larch of Olginsky and Amursky in the south of Primorsky Krai.
