Ecological assessment of the Birobidzhan culture and recreation park dendroflora

The authors assessed the state of the dendroflora of the only park of culture and recreation in Birobidzhan and gave recommendations for the improvement of its territory. They used inventory, analytical and theoretical research methods to describe the species composition of trees, their age structure and ecological state. In total, more than 2,000 specimens of tree plantations were studied, classified into 29 species, of which 4 dominate: elm squat (18% of all species), Manchurian ash (16%), sweet poplar (13%) and birch flat-leaved (7%). The assessment of the ecological condition of the dendroflora showed that 61% of the specimens are weakened, which is associated with anthropogenic and natural factors, old age and other reasons. It was noted that 27% of the trees are in emergency condition and require removal and replacement; 12% are characterized by a good ecological condition, their age does not exceed 20 years. The results of the work served as the basis for developing recommendations for specialized organizations to improve the situation with the of the town park dendroflora. They are: sanitary pruning, uprooting stumps, increasing the number of ornamental shrubs, systematic care, etc.
