AGE AND SPACE STRUCTURE OF <i>PINUS SYLVESTRIS (PINACEAE) </i>COENOPOPULATIONS IN NORTHERN TAIGA (KOLA PENINSULA)
The diversity of age and space structure of Pinus sylvestris L. coenopopulations was studied in northern taiga pine forests of lichen-green moss and lichen site types aged 85, 143 and 376 years after fire. Four main types of age structure were revealed using parameters of individual age distributions (range, skewness, kurtosis, discreteness of age series) and age distribution of wood. Space structure was studied using the fixed squares (25 m2) method. The diversity of space structure and components of coenopopulations (trees, saplings, seedlings) consisted of four different types and twelve variants that had been identified according the negative binomial distribution parameters and the share of «empty» space (where there is no pine individuals).
