Zavyalov Island is a large island in the northern portion of the Sea of Okhotsk. Visits to the island are only realistic in the summer months. During the long, dark Siberian winter it is likely that Zavyalov is iced in for months at a time. Zavyalov is mountainous and vegetated by Siberian dwarf pine and dwarf birch. Both are hardy species that can endure the bitter winters and short summers. The diminutive vegetation offers little shelter for brown bears that can be seen grazing the island’s shores in search of berries, roots, and feasting at low-tide on the shellfish at the shoreline. The coasts of Zavyalov also support breeding populations of Steller’s sea lions.
