Sakhalin Island taiga The Sakhalin Island taiga ecoregion (WWF ID:PA0607) covers most of Sakhalin Island, the largest island in Russia, and which lies in the Pacific Ocean separated only by Sea of Okhotsk and the Sea of Japan. The region is one of taiga (coniferous and mixed broad leaf forest landscape, with mixed larch forests at the lower elevations and shrubs at higher elevations.) The vegetation is heavily influenced by a maritime climate that is relatively warmer than the colder continental taiga in Siberia to the west. A long, thin island (1,000  km by 200  km), Sakhalin is connected to the mainland by ice bridges in the winter, so it shares certain flora and fauna species. It is in the Palearctic ecozone, and mostly in the Boreal forests/taiga ecoregion with a Humid continental climate, cool summer climate. It covers 403504 km2 .
