The dendroflora of the city under study is represented by 67 species of higher vascular plants, which belong to 39 genera and 19 families. The leading position is occupied by the families Rosaceae (21 species, 31,9%), Salicaceae (10 species, 14,9%), Pinaceae (7 species, 10,4%). The basis of tree plantings of the city of Abakan are the speciesPopulus nigraL. andP. balsamiferaL.;Betula pendulaRoth is also widespread. Recently,Tilia cordataMill. has been increasingly used for urban landscaping. The study of the adaptation features of small-leaved linden in the steppe zone of the city of Abakan is very important, since it will allow us to predict its further development and, if necessary, take timely measures to preserve it. In addition, it is extremely important to assess the formation of interspecific relationships betweenT. cordataand arthropods – leaf pests in the city of Abakan. Preliminary assessment showed that the most typical primary pests ofT. cordatain the city of Abakan are:Eriophyes tiliaevar.liosomaNal.,Eriophyes tiliaevar.nervalisNal.,Eucallipterus tiliaeL. The highest growth was usually observed inT. cordataindividuals in good condition. Plants susceptible to diseases and pests showed a low growth.
