title: Variety of size structure of middle-aged pine (Pinus sylvestris L.) stands in the northern taiga (Murmansk Region)
abstract: The distribution of Scots pine trees according to the gradation of trunk diameter in stands of 85-year-old northern taiga pine forests (Kola Peninsula) has been investigated. Based on the approximation by the Weibull distribution, the presence of two main types of the size structure of forest stands was revealed. The distribution shape coefficients are reliably related to the peculiarities of the habitat conditions, which are reflected in the stand basal area and the ratio of mosses and lichens
