Introduction. The necessity to improve the silvicultural activities on the slashes of small-leaved stands using the knowledge about the dynamics of space structure of forest communities in the course of forest-forming process determines the topicality of the studied problem. This problem is lack of study in the taiga zone forest. The goal of the paper is to study a long term dynamics of space structure of forest communities after felling of secondary birch groves with conservation of spruce of preliminary generation. Objects and methods. The fellings of birch groves with spruce of preliminary generation growing in the sorrel - myrtillus forest type were chosen to be the object of the research (North forest experiment station of the Institute of Forest Science, RAS, Yaroslavl oblast). Measurement was taken in 2, 7, 12, and 22 years after stand felling and it was also taken on the controlled sampling area. Dynamics of the structure of plant communities was analyzed by the groups of parcels. Results. The slashes are of vast space diversity: in 2-year cuttings, there are 3 times more parcels in comparison with the data from the controlled sampling area. The parcels were divided into 11 groups by similarity of the structure of plant communities. In 12-year old cuttings, the area of parcels with spruce has increased 60 %, which is determined with inten-sive growth of this species after removal of upper layer of birch. In the cutting area of 22-year old slashes, the parcels with young trees (38 % of the area) and polewood of spruce (21 %) predominate, aspen groves in the stage of polewood are developing(33 % of the area). Birch regeneration is 10 years later because of quick colonization of the area with woodreed and tussock-grass. The parcels with young birch (20 %) are developed in 20 years only. In the skidding trails of 22-year old cuttings, the parcels with grassy suffruticose layer (47 %) predominate. Conclusion. Location and the area of parcels on the slashes of small-leaved stands in the taiga zone forests is determined with the structure of plant community before felling, with location of engineering elements on the slash and with the time passed after felling. Study of the parcel structure in plant communities and its transformation on the slashes makes it possible to under-stand the reasons, determining recovery-age dynamics of stands which defined the choice of the system of silvicultural activities, directed to establishment of highly -productive coniferous stands.

Introduction. In the Republic of Mari El, harvesting of a great many spruce seeds and laying them on long-term storage is first and foremost explained with a vast periodicity of seeding (up to 4 years). There are no many researches on dynamics of spruce germinating capacity on long storage. Germinating capacity of seeds for the last day of germinating with no analysis of germinating capacity in the days of intermediate accounting are considered in most of the existing researches. The goal of the research is to define the optimum storage period for the spruce seeds and to analyze the dynamics of their germinating capacity on long storage. Objects and methods . The seeds were harvested in the Republic of Mari El in winter- 2007/2008 in the middle-aged, ripening and mature stands. All the harvested seeds fall under the category of natural seeds. The germinating apparatus of forest plants PLUS.441352.001 RE was used to define the germinating capacity of seeds at a water temperature of 24 ºС (night mode) and 36 ºС (day mode). One hun-dred seeds in four repetitions of each of 14 seed lots were used

Introduction. Definition of remaining life time of high-pressure hose, the fault of which is of sudden nature, is one of the topical technical problem, intended to improve the reliability of performance of hydraulic drive of forest machines. This problem is not solved to the full and it is required to improve the diagnostic technique of current condition of high-pressure hose. The goal of the research is to improve the efficiency of forest machines operation due to failure prediction and full employment of resources of the parts of hydraulic drive. High-pressure hoses of forest machines (Forwarder 1910F, Finnish production), exploited in summer and winter in Priluzhskiy district of the Komi Republic were chosen to be the object of the research. Results. The experimental researches to define the mode of vibration, arising when their dynamic loading, were carried out. It was demonstrated that the oscillating process coming from the resonance state of a pipeline arose under certain pressure of loading in the pipeline. In this regard, free frequency of pipeline with liquid was chosen as a testing parameter, dependence on the cycles of dynamic loading was determined, frequency function of failure distribution was found, a method to define probability of failure of the parts of hydraulic drive was offered. The method allows to determine the remaining life time of the parts of hydraulic drive. Free frequency of pipeline with liquid was taken as a testing parameter , describing technical condition of high-pressure hose . Conclusion. The formula of probability of failure of pipeline in summer and winter was derived. It was shown that loss of life of high-pressure hose at low temperatures is explained with the peculiarities of rubber properties it is made of.
