Evaluation of the efficiency of the Nature Reserve Fund of Sumy region according to the Insularization Index

Abstract

The aim of the work is to assess the quality of the natural reserve fund of the region. The article presents the results of calculating the insularization index of the nature reserve fund of the Sumy region. Namely, data on what is the share of unstable objects in relation to the total number of protected objects. Calculations were carried out for all districts of the region for the past administrative division and for the current one. Also, the degree of conservation in areas with the highest and lowest values of the insularization index is considered. After performing the calculations, it was found that the values of the insularization index are high for most areas of the previous administrative division. This is so, because in 10 out of 18 districts the share of protected objects, the area of which is less than 50 hectares, is predominant. The highest value of the index was recorded relative to such areas as Lipovodolinsky District, Yampolsky and Trostyanetsky. The percentage of protected areas in these areas is also low. The smallest are the shares of unstable protected objects relative to the total number in Shostinsky, Konotopa and Seridino-Budsky regions. But the percentage of protected areas in Shostinsky and Seredina-Budsky districts is low. For the districts of the new administrative division, the number of which is now 5, the situation is even worse. So, in all regions the share of unstable, rather ecologically unstable objects is predominant. The highest values of the insularity index were found in two districts at once, namely in Shostinsky district and Akhtyrsky district. The smallest number of unstable protected objects was recorded in the Konotop area. The value of the insularity index of the Sumy region is somewhat large. But in general, the indices are quite high, and work is aimed at improving the situation, of course, should be carried out in these areas. In total, according to the results obtained, the following conclusion was formed that the share of unstable objects of the reserve fund was predominant in most areas of the previous administrative division. The new zoning did not affect the increase or decrease in the share of unstable objects in the region as a whole, but as a result of the restructuring, it increased relative to those districts that became the basis for new districts. However, as a result of the merger, there were also positive prospects.
