Habitat systematisation and the questions of Eastern Fennoscandian forests dynamics

The article, which is a summary of the lecture presented to the IV Geobotanical School (Ufa, 2012), discusses the issues of habitat systematisation based on types of ecotope and vegetation. The author describes a step-by-step solution to the problem of classification of zonal habitats and secondary forest communities at different development stages. There are several methods for classifying such objects, but the most effective solution involves formulating specific practical use and can only be based on the knowledge of the structure and dynamics of the forest communities being classified.
