Forest is a complex dynamic system that is constantly changing under the influence of various biotic, abiotic and anthropogenic factors. Therefore, the question of updating information on these changes is always relevant. Based on the stand- (as of 01.01.2011) we have analyzed distribution, current state and detailed mensurational characteristics of ash stands that grow in Ukraine. We have calculated the main mean mensurational indices for ash stands and conducted a detailed analysis of growth of this tree species in terms of origin, type of site conditions, age structure, site index classes, relative stocking and share of the tree species in stand composition. The results show that ash stands grow mainly in rich in terms of soil fertility and fresh or dry in terms of soil moisture conditions (most common conditions D₁, D₂, D₃, C₂ and C₃) but their productivity is higher in wet conditions. In terms of stand origin, vegetative sprout and artificial seed stands are dominant. Distribution by age structure is close to normal with a predominance of mature and immature age groups of stands. The mean site index class equals I,7, mean relative stocking 0,72, mean growing stock 216 m³ ha^-1.
