Contemporary Ecological State of Pine Biogeocenoses of the Krasnoyarsk Forest Steppe

An assessment is given regarding the current ecological state of pine biogeocenoses components (forest stand, undergrowth, living ground cover, and soil) in the Krasnoyarsk forest steppe growing in both the zone of long-term anthropogenic impact of Krasnoyarsk and under natural conditions (control plot). Studies are carried out on monitoring sample plots in forb pine forests. The current state of pine forests growing in the zone of long-term anthropogenic impact of Krasnoyarsk is assessed as satisfactory. The sanitary and vital state of suburban pine stands does not differ from background ones. A good rate of pine regrowth has been established in the pine forests. The presence of seedlings and a significant amount of viable undergrowth has been recorded. The living ground cover in pine forests at the moment is at the stage of weak recreational transformation (with the exception of the control sample plot). The soils under the studied pine stands in the zone of influence of the city are anthropogenically transformed and have developed profiles with signs of degradation of the upper horizons.
