The Shantar Islands lie on the eastern side of Uda Gulf; until 9,000-10,000 years ago they were connected, which explains why there the floral ecosystem of the island contains no endemic species. Of the 15 islands and many rocks that rise above the surface, two make up 75% of the terrestrial area of the park: Bolshoy Shantar Island, and Feklistova Island which is about 20 km west of Bolshoy Shantar. Uda Gulf separates the main islands from the coast to the west. Tides reach 5 – 8 m, and currents around the island are very strong. Fog is frequent.
Climate and ecoregion
The climate of Shantar Islands is more severe than that of the Okhotsk Sea in general. The prevailing northeast winds push ice floes into the coast around Shantar, leaving only 2–3 months per year of ice-free water. The official climate designation for the Shantar area is "Subarctic climate", with long, cold winters and short cool summers. The maritime ecoregion of Shantar Islands is "North Temperate Indo-Pacific / Sea of Okhotsk",, characterized by cool but fertile waters that support enormous fisheries and bird centers. Currents keep the areas near the coast cooler than areas to the east; the variety and proximity of temperature support the high levels of biodiveristy.
Plants
The larger islands are covered with dark coniferous forests, primarily Siberian spruce, larch, cedar, and birch. There are no endemic plant species on the islands, as they are close to, and until relatively recently connected to, the mainland.
Animals
Park rules will protect the maritime environment, with fishing prohibited out to 1–3 miles from the coast to cover salmon spawning areas. Terrestrial mammals include brown bear, caribou, red fox, sable, river otter, and ringed seals. Over 240 species of birds live on or migrate through the Shantars, including the endangered species such as the Blakiston's fish owl and Steller's sea eagle.
History
The islands have a long history of visits by humans for use as bases for fur trapping, whaling, fishing, and hunting. American whaleships hunted bowhead whales around the islands between 1852 and 1907. Logging has occurred in past, and the islands are in a region with potential mineral reserves - all adding pressure on the site for economic use. The islands were set aside as a state nature reserve in 1999, and except for a meteorological station and occasional scientific camps, are now uninhabited. In 2017, further protections were accepted to divide the area into several zones and will completely ban any economical activities within certain area.
Tourism
The park is still being established, with rules, infrastructure and zoning being developed. Ecotourism, education, and scientific study are all stated in the plans for the territory. There are commercial tour groups operating in the area.
