STATЕ OF NATURAL OAK FORЕSTS OF ZHMERYNSKE FORЕSTRY

Abstract

The article shows the problems of researching the state of natural oak forests of the branch "Zhmerynske LH", which is in the functional structure of the regional forestry and hunting economy department of Vinnytsia region. In the research material of the article, an analytical review of the specialized enterprise's forest management database is carried out. The result of the analysis of forest management data and visual inspection within the forest areas of the Zhmerynske Forestry Branch is the determination of the taxonomic indicators of oak forest plantations of seed and vegetative origin. The preserved natural oak stands within the forest areas of the branch "Zhmerynske Forestry" grow in optimal forest and vegetation conditions. The vast majority of natural oak stands grow in fresh hornbeam forests and less in wet hornbeam forests. It has been established that natural oak forests within the forest fund of a forestry enterprise are represented by vegetative and seed plantations by origin. Analytical data show that there is a tendency to reduce the share of natural oak forests within the enterprise. It has been determined that the enterprise is dominated by oak forests of natural origin with a share of 9-10 units of oak, mostly 110 years old. The area of these plantations is the maximum and amounts to 159.3 hectares. It was found that the oak stands are characterized mainly by the 2nd class of bonita. The average stock ranges from 310-342 m3/ha. The result of the research is the establishment that in natural oak forests there is almost no sustainable natural regeneration of the main forest-forming species. Also, based on visual inspections, it was found that in the conditions of fresh pile, natural regeneration of oak is not found in the existing forest types.
