Изложена краткая история биогеоценотических исследований Института лесоведения РАН на территории Серебряноборского опытного лесничества под Москвой. Создана сеть постоянных пробных площадей, на которых ведутся регулярные наблюдения за древостоем и напочвенным покровом. Изучается рост сосновых и лиственничных культур различного происхождения. Ведутся наблюдения за микобиотой Серебряноборского лесничества.

The history and results of long-term silvicultural and geobotanical studies, begun in 1947 on the territory of the Serebryanoborsky experimental forest district of Institute of Forest Science RAS, are presented. Descriptions of the main types of the forest vegetation area were made and their map was compiled. Also compiled soil map of forest district. In 1947, the first permanent sample plot was laid to monitor all layers of vegetation. Later, a system of 53 permanent sample plots was created, covering the whole variety of indigenous and derived forest types. Regularly checkups of the forest district flora composition have been being conducted. Protected plant species have been identified and are regularly monitored at permanent sites. One of the main causes of vegetation dynamics in forest district was changes in anthropogenic influence. Livestock grazing was prohibited, but at the same time, recreational loads increased in a large part of the territory. The maps of recreational disturbance of the forest district were made twice. It has been established that the age of natural maturity of forest stands of complex boron does not occur earlier than 200-220 years. Studies of geographical cultures of pine and larch, created in 1948-1950, allowed to establish comparative features of different provenances of pine and different species and forms of larch, including the unique Far Eastern ones, in the conditions of the Moscow region. The study of the growth dynamics of experimental different density pine plantations, established in 1948, led to the conclusion about the optimal planting crop density of 28 thousand trees per ha. At the Experimental Test Site, established in 2002, the influence of recreation of different intensity on the dynamics of all components of pine forests is studied. Over the years, a study of the mushroom biota of the Serebryanoborsky experimental forestry was conducted. As a result of the research, data on the diversity of forest mycobiota have been accumulated, the most important tree species pathogens have been identified, information on their distribution and harmfulness has been obtained, and a phytopathological assessment of the success of growing Scots pine climatypes has been carried out in experimental geographical cultures that have reached adulthood. An inventory of dendrotrophic fungi species composition is currently being carried out, an information base is being formed in order to monitor the diversity of fungal biota and phytopathological monitoring in the territory of an experimental forest range.
