Abstract
The provision of softwood plantations with undergrowth of Siberian Pine (Pinus sibirica Du Tour.) in Western Siberian north-taiga plain forest region was analyzed on the base of the forest management data. It was noted that there is Siberian Pine undergrowth only on the territory of the core Soviet forestry in Khanty-Mansiysk Autonomous Okrug – Yugra on the area of 25.6 thousand ha. It includes 24.6 thousand hectares where the amount of undergrowth is sufficient to ensure the formation of young Siberian pine on its basis.
The main areas of softwood plantations with the presence of Siberian pine undergrowth are represented by derived stands formed on the site of felling and burned areas of cedar forests of the green-mossy and grass groups of forest types. The latter indicates a high potential productivity of young Siberian pine under the condition of preserving the undergrowth and the proper type of felling. The maximum number of Siberian pine undergrowth accumulated under the canopy of mature and overmature soffwood plantations with relative fullness in green-moss and grass groups of forest type is 0.7. And it is 0.5 in plantations of grass-moss groups of forest type. The latter is necessary to take in to account when choosing the type of felling and setting the intensity of thinning.
