| Summary: | The aim of the research is to identify successions of climax forest systems within the southern taiga of the European part of the country (Kostroma region). The main objective of the research is to establish the directions (spectrum) of successions of spruce and pine forests in the southern taiga of the Kostroma region in different types of forests. Studied the identifi cation of the frequency of occurrence of successions of spruce and pine forests as well as ecological and biological evaluation of series of forest communities compared to the climax. The object o research was the forest Fund Lomcovsky district forestry, is located in the southern taiga of the Kostroma region. This territory is typical for the southern taiga of the European part of the country by the main physical and geographical parameters. The standard forestry methodology was applied in the course of the studies. As a result of the research, it was found that about half of the successions occur in the spruce forests of sour and blueberry (29 and 28 %, respectively) due to birch. From important successions are also changing sorrel spruce to aspen (6 %) and pine (6 %), on spruce blueberry aspen (7 %), spruce fern, moss and grass-bog birch (6, 4 and 3 %, respectively), as well as the forest moss on birch (3 %). In total, these types of successions account for more than 90 % of shifts. The successions occur in the most productive habitat conditions (sorrel spruce forest (41 %) and blueberry (36 %) in wet suramine). At the same time, 95 % of successions occurred in spruce forests and only 5 % in pine forests. Most often successions occur on birch (75 %), aspen (13 %) and pine (10 %). The predominant climax vegetation formations on the territory taken for consideration are pine and spruce. The latter has a more widespread especially in the upland areas, which led to a wider range of succession in the spruce forest.
