This study examines the structure of vegetation and the relative distribution of plant biomass in natural and cultivated cenoses developed on dark mountain chestnut soils of the Aghdara region (Azerbaijan). Field observations were conducted in two contrasting ecosystems: natural steppe vegetation and an agricultural forage community. The analysis focused on the dominant plant groups and their contribution to the formation of above-ground biomass. Results showed noticeable differences in the proportion of fresh and dry biomass between natural and cultivated environments. Natural plant communities demonstrated a more stable vegetation structure and a higher share of structurally persistent biomass. The findings highlight the important role of vegetation cover in maintaining soil organic matter and ecosystem stability.
