【 摘 要 】

Phytosanitary and ecological estimation of tree-stands has been con­ducted atthe Forest Experimental Station of Moscow Agricultural Academy and parks ofNortheast of Moscow in 2007-2011. Fomes fomentarius was proved to be a veryserious pathogen of trees under conditions of Moscow, Piptoporus betulinus,Phellinus igniarius, and Fomitopsis pinicola also occurred and caused damageto trees. This rather bad phytosanitary situation depends on alarmingecological situation in Moscow. At the Forest Experimental Station of MoscowAgricultural Academy a number and cover of lichens decreased. In general, alltrees in Moscow are in dynamic equilibrium with the urbanized environment. Inconnection with this, the following classification of tree-stands wasproposed for the urbanized environment: 1 - healthy trees, 2 - affected treeswhich can be managed, 3 - dry woods, 3a - very diseased. Many tree-stands ininvestigated regions of Moscow are found to belong to the groups 2 and 3c.All tree-stands must be carefully monitored and managed in order to provide awell-timed decision on the support system for preservation of trees as ‘lungsof city’ and avoid unpredictable tree falling which put people and traffic atrisk.
