The condition of natural complex of oil-gas condensed deposits of the Ymalo-Nenetsk region is investigate. The content of heavy metals (Cu, Cu, Zn, Ni, Co, Pb, Mn, Cd, Hg, Ba, V, Cr), arsenic, oil-hydrocarbons (OHC), polycyclic aromatic hydrocarbons in natural water, bottom sediments, soils and indicator plant lichen (Cladonia alpestris (L.) Rubh), ledum (Ledum decumbens (Ait.), cowberry (Vaccinium vitis-idaea L.) is determined. The basic indicator of antropogenic pressure on the landscape component is established. The indices of pollution are higher concentration: Ba, Hg, Zn, Cu, Pb in soil naphthalene and OHC in peat and mineral layers of soil simultaneously; Ba and OHC in natural water; Ba and naphthalene in bottom sediments; Ba, Zn in indicator plants in cowberry (Vaccinium vitis-idaea L.), Ba, Zn, Ni in ledum (Ledum decumbens Ait.), Ba, Pb in lichen (Cladonia alpestris (L.).
