Radial growth of artificial forest stands under the aerotechnogenic impact of the Orenburg gas chemical complex

With extremely low forest cover in the Orenburg region (4.6 %), where the environmental stress factor is particularly acute, forests have exceptional climate control, soil protection, and sanitary and hygiene. The priority area of practice and science is the preservation and growth of the forests of the region, which serves as a kind of framework in stabilizing the environmental situation in the region. The presented work shows the state of forest stands under conditions of anthropogenic impact. The culmination of the current radial growth has been established and the so-called "surge" of the current growth of tree stands has been detected with the accumulation of threshold levels of toxicants in a polluted environment, which subsequently leads to loss of stability and destruction of plantations.
