Abstract
Larix decidua Mill. is a breed planted for initial introduction testing more than 120 years ago on the territory of East Prussia, now the Kaliningrad region. These plantings are of considerable interest in terms of the success of the introduction. An assessment of the taxation indicators has been carried out, specifying the age of individual trees, the number of plantings, its sanitary condition, the species composition of related species, the composition of the undergrowth, the presence of undergrowth and its condition, the presence and abundance of self-seeding. The characteristics of the soil cover are also given. In the studied area, the type of forest conditions is D2, and the type of forest is linden larch. Plantations are developing according to the I growth class, as part of the European larch stand from 6 to 10 units, the wood stock is 322–386 m3/ha. A comparison with the 2013 taxation figures showed that the allotments differ little in terms of the composition of the plantation and the stand density at the time of the study. A noticeable difference is observed in standing crop. The sanitary condition of the surveyed sample areas has been determined on a scale of tree condition categories and classified into categories of living conditions that differ in two quarters: in quarter 32, the state of the stand is classified as "weakened", in quarter 171 – as "healthy". In the Kaliningrad region, European larch has successfully acclimatized and adapted well to local conditions. However, in block 32, due to the aging and high density of trees, the population becomes less stable, pests appear that damage the trunks, and the risk of windstorms increases. Undergrowth or self-seeding of the main breed, European larch, have not been found in the test areas and on the neighboring allotments.
