THE ESTIMATE OF NATURAL REGENERATION OF SIBERIAN PINE IN MIDDLE TAIGA ( WESTERN SIBERIA) UNDER FOREST CANOPY AND ON CLEARINGS
Introduction. In 2017, the rules of timber harvesting were updated. One of the most significant innovations was the decision to cut down Siberian pine forests with a share of Pinus sibirica in the composition of stands 25-44 %. Despite the fact that under public pressure this decision was canceled, it is of interest to solve the problem of reproduction of Siberian pine forests. The aim of the research was to summarize the results of study of peculiarities of Siberian pine forests reproduction under the canopy and on the clearings of parent stands and secondary stands based on the example of middle taiga,Western Siberia. Objects and methods. The research was carried out on the territory of Verkhneketskiy forest district (Tomsk region), located in the сentral part of middle taiga. The research was carried out using the method of test areas. In the course of the research, 30 test areas were established under the canopy, 28 test areas - on the clearings. Results. Regeneration of Siberian pine is successful in most types of stands. The undergrowth is represented with small specimens, so there is a need for felling care. Another direction is the implementation of selective felling. Advance regeneration plays the principal role in recommencement of the clearances of Siberian pine and other similar stands. The most unfavorable types of cuttings for regeneration are formed after summer logging. In this regard, felling in the snow-free period in Siberian pine forests should be completely excluded. Conclusion. Study of Siberian pine regeneration under the canopy and on the clearances shows the possibility of Siberian pine recovery in a natural way.
