The park is designed to protect west-slope river valley habitat, and to support the remnant of the indigenous Udege people.

The main river valley of the Ussurka runs to the north-northeast, along the Sikhote-Alin fault, it is passable to small boats in lower region, with oxbow lakes and marshy banks.

This climate is characterized by large swings in temperature, both diurnally and seasonally, with mild summers and cold, snowy winters.

It is also a geological contact region between ancient (Achean-Proterozoic) stable base rocks to the west, and more active tectonic formations to the east in the Sea of Japan.

Furthermore, it is on major migration routes of birds and other animals, and has a topography that escaped both recent glaciation and human development.

[9] The resulting diversity of habitats and isolation gives the Primorsky region the highest levels of biodiversity in Russia.

The park records 30 species of vascular plant requiring protection in the area, including Japanese mountain yam, fox nut, Pacific saxifrage, ginseng, and yew.

Smaller forest mammals are sable, marten, badger and weasels, along with lynx and leopard cat.

The park administration provides some accommodation in a guest house and campgrounds, and provides for rental of snowmobiles and inflatable rafts.
