"Serebryanoborsky" experimental forest district - the main basis of biogeoceneological researches of the Institute of forestry of the Russian Academy of Sciences in the middle strip of Russia

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...
