    New approaches to the analysis of the structure of the consortium of woody plants are considered. The structure of the consortia of Betula pendula Roth and Tilia cordata Mill. of various ontogenetic conditions in the districts of Yoshkar-Ola and the Republic of Mari El, Russia is described. There are 126 species of arthropods (Insecta and Arachnida) associated with Betula pendula cenoses, and 129 species for Tilia cordata. It is shown that the diversity of tree consortial connections characterizes the quality of the environment and indicates the degree of stability of its population to the anthropogenic load. For the first time, a parametric method for visualizing the structure of a consortium was used. The order of filling of separate ecological niches of consortia, connected with ontogenetic state of the determinant of a consortium and the supposed degree of anthropogenic load is revealed. This allows us to hope for the possibility of using the parametric imaging method for bioindication purposes. It was suggested that for the detailed characterization of the consortium, it is necessary to organize a long-term monitoring of the state of woody plantations and the composition of their consorts
