The considerable age of shelterbelts, intensive farming practices and global warming lead to deterioration of their functioning and depression. The aim of the study is to analyse the current agrobiological features of shelterbelts in the Right-Bank Forest-Steppe under conditions of intensive agriculture and global warming. The study was conducted within 25 forest belts on defined test sites 100 m long in four replications. The number of tree rows in each forest belt, the distance of trees between rows and in rows, the width and height of the forest belt, the girth of the tree trunk at a height of 1.3 m, and the spread of diseases and pests on the leaves of trees were determined. The number of tree rows in shelterbelts varied from three to nine. The main shelterbelts had 5-9 rows of trees, and additional shelterbelts had 3-4 rows; the blowing shelterbelts had 4-5 rows, and the dense shelterbelts had 9 rows. The distance of trees between rows in different shelterbelts was 1.0-3.5 m. Additional shelterbelts had a 1.5-3 times wider row spacing than the main ones. In the rows of shelterbelts, trees were planted at a distance of 1.0-2.0 m. Blowing shelterbelts were created more sparsely, and dense shelterbelts were created more densely. There was no difference between the distance of trees in the main and additional shelterbelts of the same design. The greatest tree thinning in the rows of shelterbelts, compared to the designed planting, was found in the dense main forest belt - 70% and the blown main forest belt - 60%. In the other shelterbelts, tree thinning in the rows was also significant and amounted to 50%. The width of shelterbelts varied from 7 to 20 m. Dense shelterbelts were the widest, and the narrowest were the blowing shelterbelts. Most of the diseases and pests were found on the maple in the dense forest belt. Powdery mildew was developing on 30% of the leaves and rough eating of 45% of the leaf surface was detected. The largest number of trees with drying tops and lateral branches was found in the main blowing forest belt: 20 per cent of the ash trees and 37 per cent of the maple trees, as well as 15 per cent of the ash trees in the main openwork forest belt
