The planned Middle Ussuri National Park will be  located in Krasnoarmeisk District to include part of the basins of Bolshaya Ussurka and Armu Rivers in the area of Dalnii Kut and Dersu, and also the lower section of River Perevalnaya valley (area 109,000 ha).
    The range boundaries of numerous flora and fauna species pass here. Cedarbroad-leaved forests, cedar forests and valley broad-leaved forests determine the high level of biological diversity.
 Today none of the existing sanctuaries or preserves retain the valley complex of rivers characteristic of the Sikhote Alin macroslope. The creation of this national park will solve this problem.
    Thirty-one rare vascular plant species and those requiring protection (the Japanese yam, the Sakhalin ephiliantis, the tuber Calipso, etc.) and twelve Red Book lichen species grow here. Seventy bird species nest here, including nine rare and disappearing species (the fish owl, the scaly Mergur albellus, etc.); over twenty-five mammal species, including the Red Book Amur tiger and Himalayan bear, and up to ten thousand insect species, including rare and disappearing species (Schrenk ground beetle, Eversmanns Apollo, etc.) inhabit the area.
    The need to protect natural complexes caused  the main area of the planned national park to be incorporated into Sikhote Alin. Subsequently, in 1951, with decrease in Sikhote Alins area, it ceased to be reserved, but retained its significance as a   biological diversity range.
    In addition to its high nature protection significance, the area of the planned national park continues to be  a center of economic activity for  one of the last Udege branches, the Iman group.
    The creation of a national park would among other things be designed to provide representatives of small peoples with their traditional work and consolidate their habitat to present a unique opportunity to revive the ethnic and cultural community of the indigenous population. The area is also valuable historically and archeologically, given the forty-one archeological monuments registered here.
    The Middle Ussuri range became popular with hikers since the nineteen-thirties, and the  Armu River is one of the favorite sights in Primorye. Russian national hiker and composite routes, including the most complicated ones, pass through  the area.
