Evaluation of status of tree plants on anatomo-morphological indicators during the conditions of Kedrovsky coal mine

The anatomical and morphological characteristics of woody plants (Pinus sylvestris, Betula pendula) growing under the conditions of the rock dump of the Kedrovsky coal mine are studied. Species-specific anatomical changes in woody plants have been identified that are adaptive in nature and contribute to their survival in extreme environmental conditions. Pine has a reliable increase in the assimilating surface of the needles, a thickening of the epidermis and a slight thickening of the endoderm, with an increase in the number of resin courses, an increase in their diameter was noted. The size of the cells of the lower epidermis increased in birch, and the number of stomata per unit surface of the leaf increased.
