Preservation of century old trees is of great ecological importance, particularly for modern recreational areas. The evaluation of the qualitative state of century old trees in recreational area of Koncha-Zaspa at the sanatorium "Zhovten" has been done. The study included determining the age of the treеs, morphometric parameters, drought resistance, disease prevalence. It was also evaluated the role of abiotic factors destabilizing the state of the trees. It was determined that the oaks are in poor condition because of the significant anthropogenic pressure, so the trees are weakened and affected more than 10 plant pathogens. The certain measures for trees protection and improving of their vitality was proposed.
