The article presents the evaluation of the stability of vegetation in forest ecosystems, in places of mass rest in the woods on a lake in the littoral zone of pine forests of the Mari El Republic. Studies have shown that the amount of coniferous undergrowth ranges from 0.016 thousand PCs/ha to 0,104 thousand pieces/ha, and does not provide the initial stage of the formation of dark coniferous young growths. For deciduous species, mainly birch, in some cases, aspen is characterized by intensive growth, which prevent the resumption of coniferous trees, and they grow much slower. The most appropriate event for the organization of recreational use of forest areas is the preservation of basic types of forest care, selective logging;
The proposal to use the method of analytical differentiation, for assessing the growth of the younger generation and timing of selective cutting. Calculations by the method of analytical differentiation showed that the growth and acceleration of growth of trees is increased, and the growth rate decreases. In the end in the recreation area near the lake to enhance the growth of coniferous undergrowth is necessary to take measures for the removal of part of deciduous trees. As a result, we increase the light, which can reduce the competitive effect on coniferous young plants. In this case, we recommend to remove the trees in the landscape. Time logging is determined at the time of the analysis . The beginning should be from an early age, when the reduced growth in height within a few years.

Keywords: recreation, pine forests, the results of natural regeneration, characteristics of the undergrowth, the method of analytical differentiation
