FIELD: agriculture.
SUBSTANCE: invention relates to engineering biology and environment indication. The method comprises selection of accounting birch trees. On each accounting tree relative to the cardinal points on the lower part of the crown the test branches are selected with leaf fluctuating asymmetry. Along the perimeter of the birch forest at least 10 accounting birch trees are selected. Then, on each accounting tree on the four cardinal points the selected test branches with leaf fluctuating asymmetry are marked by label. The height from the point of the label location to the soil surface is measured, and the distance from the label location to the boundaries of birch forest is measured. Additionally, the distance from the boundary of the birch forest to the trunk of each accounting birch is measured. The circumference of the trunk of accounting birch is measured. Further, according to the results of the measurements obtained, the statistical modelling is carried out with the definition of the correlation coefficient of the obtained statistical models on the measured parameters. According to the correlation coefficient the ecological assessment of the status of the territory is carried out.
EFFECT: technology enables to expand the functional capabilities of assessment of the ecological state of the territory through the use of proxy indicators, as well as to improve the accuracy of indication of the quality of the local environment surrounding the birch leaves.
