The article highlights the problems of researching the state of natural oak forests of the Dashivske State Forestry and Hunting Range Branch of the State Enterprise «Forests of Ukraine», which is part of the functional structure of the Central-Western Interregional Forestry and Hunting Administration. The article presents an analytical review and systematization of the data obtained from the forest management database of the forestry enterprise. The result of the analysis of forest management data and visual inspection within the natural oak forests of the Dashivske SFE branch is the determination of taxonomic indicators of natural oak forest plantations of seed and vegetative and seed-vegetative origin. It has been established that natural oak forests within the forest fund of the Dashivske SFE are represented by vegetative and seed plantations, and one site is seed-vegetative in origin. It has been determined that the largest areas of plantations are of the 7th age class – 64.0 hectares and the 9th age class – 77.9 hectares. The smallest areas are occupied by natural oak plantations of the 3rd age class – 2.4 hectares and the 6th age class – 7.4 hectares. It has been established that the largest participation of oak in the composition of stands (6-5 units) is characteristic of stands of the 11th age class. The lowest proportion of oak is in stands aged 20 to 40 years. In these stands, oak participation can decrease to 1-2 units, which indicates the complication of the conditions for natural oak. It was found that the largest total stock is characterized by stands of the 7th, 9th, and 11th age classes, which is due to their largest areas and quite high productivity, respectively. The largest average stock of stands of the 8th-9th age classes is 310.0-272.9 m3/ha. The data obtained from the analytical review and visual observations accompanied by measurements show that there is a tendency to reduce the share of natural oak forests within the enterprise. The results of the research show that the natural oak forests of the surveyed enterprise mostly lack sustainable natural regeneration of the main forest-forming species. Also, on the basis of visual inspections, it was found that in the conditions of fresh piles on the site of a fresh hornbeam-ash oak forest, natural oak regeneration occurs.
