Abstract: Ecological-coenological vitality and structural development of forest ecosystems is the main goal of forest management planning aimed to protect and improve the environment. It particularly applies to special-purpose forests, and even more to the subcategory of forests of special importance located in the narrow urban and suburban zones. The aim and layout of the research conducted in the suburban zone of the city of Belgrade (MU ‘Lipovica’) were defined following the above stated. The paper presents an analysis of ecological and coenological vitality of artificially established stands of Austrian pine and common ash grown on a secondary site characterised as the Hungarian oak-Turkey oak forest type (Quercetum farnetto-cerridis) on brown forest soil. The research results showed that artificially established common ash stands are significantly more vital than artificially established Austrian pine stands. In that sense, if we want to achieve ecological stability and vitality of the stand and the entire complex, the common ash stands should remain in the given site in the following planning periods. Regarding the Austrian pine stands established in the site of Hungarian oak-Turkey oak forest type (Quercetum farnetto-cerridis) on brown forest soil, future functional plans should revise the planning procedure to conduct restitution and establish the primary forest type structure. The ultimate goal of future silvicultural measures in the research area is to achieve complete functional stability and vitality of the stands established in the site of the Hungarian oak-Turkey oak forest type, which would, in turn, improve the diverse ambient of this important forest complex.
