The reserve also protect cultural and architectural sites, including some related to the indigenous Khanty people.

[1][2] The Little Sosva Reserve terrain is of one extensive wetlands around a complex system of meandering rivers.

The meandering riverbed is boulder-pebble with many sandbars and cliffs at the turns, and rapids in places where the course narrows.

[3] Malaya Sosva is central: its floral communities include species from Europe to the west, the classic taiga (forest, meadow, and marshes) of the West Siberian Plain, some species of the southern steppe, and som of the northern taiga / tundra.

[7] Throughout the reserve, waterlogged downed pine trees support communities of sphagnum moss, bog vegetation, small shrubs (rosemary, blueberries, cranberries) and sedge and grasses).

They are mostly typical of the middle taiga of the Western Siberian Plain: Siberian Chipmunk, brown bear, sable, ermine, elk, and grouse[8] As a strict nature reserve, the Little Sosva Reserve is mostly closed to the general public, although scientists and those with 'environmental education' purposes can make arrangements with park management for visits.
