Both ecological aspects i.e. biotic and biotic factors were analyzed and studied in black pine plantations in the Šumadija region. The black pine plantations analyzed within 5 experimental fields are 30, 40 and 55-60 years old, and are found in: good quality habitats medium quality habitats and low quality habitats. The same-aged plantations were studied in different habitats. All dendrometric measurements were performed, including diameter, height and tree volume, along with tree analysis and complete growth calculation. Stand structure, thickness, height, structure by basal area and volume structure are also presented. Height growth proved to be a new significant indicator. Conclusions were drawn, and tending practices for each experimental field and growing recommendations were suggested.
