Influence of the natural and climatic factors on variation in a crown shape, mechanical resistance and an accident rate of woody plants on the example of Juniperus virginiana L

Abstract

It has been experimentally found that the mono groups of Juniperus virginiana L. have less resistance to the natural and climatic factors, this is firstly due to increase in the height of biomass of the tree and secondly to application of loads in the form of a wind force, as well as an additional mass in precipitation. According to the results of diagnostics of the state and monitoring of sustainability of Juniperus virginiana L.plantings, the accident risk is estimated at 14% of the total number (585 units).
