Biogeochemical studies of  plants and soil cover in  specially protected natural areas are necessary for conducting background geochemical monitoring in order to  determine the  content of  trace elements in  plants of  natural ecosystems and to  establish the  relationship between trace element composition and environmental factors. The  atomic absorption spectrophotometry was used to determine the content of trace elements Mn, Fe, Zn, Cu, Cr, Co, Ni, Cd, Pb in wild herbaceous plants and the  root layer of  soil in  the  Nizhny Kama National Park (Kama valley and its tributaries). Species with a high content of Ni were found. High concentrations of Fe, Cr, Pb in the phytomass of mosses were revealed, which may indicate their aerogenic supply from nearby industrial enterprises. It was established that the soil cover of the national park within the Yelabuga region is characterized by  an  increased content of  Mn and Co. The  trace elements that are  vigorously absorbed by plants, as well as species characterized by high biogeochemical activity have been identified – Aegopodium podagraria L., Fragaria vesca L., Paris quadrifolia L., Anemonoides ranunculoides L., Dicranum Hedw
