50 species of mammals, about 240 bird species, over 30 species of fish live in the reserve. The reserve is famous for the high number of a bear – not without reason one of forest areas is called "The coast of brown bears". In the reserve it is possible to meet such rare and interesting birds as a sea eagle-belokhvost, a black stork, the hook-nosed tourist's sir,, a gray crane.
Completely treeless bogs on the area are small. For floodplains shrubby and grassy associations are characteristic. On loamy soils of a nadpoyma grow fir-tree and birch and birch fir forests with impurity of a fir and a cedar. In a ground circle the moss cover prevails, ferns, club mosses and horsetails sporadically meet. From floral constantly meet a wintergreen, a kislitsa,, a sedmichnik, a maynik, a gudayer, a hiding place,, the few cereals and a sedge. From berry bushes: bilberry and cowberry.
Hamar-Daban represents system of a massif with roundish forms of tops without sharply expressed crest. Mountains abruptly break to Baikal and are a natural barrier to the air streams postponed through Baikal that is followed by intensive allocation of rainfall which drops out more than on adjacent spaces of Siberia here. The humid climate promotes a rich variety of mountain and taiga vegetation.
Preserving the forests having the water preserving, soil-protective or climatic value, restoring and increasing the number of valuable animals and birds, and also protecting places of a molt and wintering of waterfowl and a spawning area of fishes, reserves carry out big economic tasks.
In the main territory (Northern Urals) the great interest represents a combination of the arkto-Alpine elements of the modern tundra to more southern and steppe species of plants. Subalpine meadows and krivolesye meet not at all tops and do not occupy extensive spaces. In a forest belt the cedar and fir-tree and fir woods prevail.
Reserves became tanks of rare animals and plants. Only thanks to reserves it was succeeded to preserve such endemic and relic animals: as the flamingo, a white heron,, a bison, a pendent, a spotty deer, gorat, a beaver, a muskrat,, a cat and many others.
The main objective of reserves consists in the most strict protection of standards of the wild nature of the corresponding zone and landscapes for comparison and the analysis of those changes which makes to the nature of people. It is necessary to remember that saving of all animal species and plants living on the earth has important scientific and practical value. It is that precious genetic fund which can appear the extremely necessary for mankind.
The flora of the reserve is various: on a flat site lichen and zelenomoshno-lichen pine pine forests, and also pine forests cowberry shrubs prevail. Water separate spaces with excess moistening are occupied by the pine woods in different stages of bogging and a pine light forest on sfagnovy bogs.
For drawing up the scientific forecast of changes of environment further, estimates of influence of various forms of human activity on natural complexes and search of methods of the most rational operation of natural resources exclusive value get reserved territories. And as standards of natural ecosystems they demand complex research. Need to have standards of all main ecosystems and, therefore, to improve and expand a reserved network is obvious.
In the territory of park 291 species of animals, 3 look amphibious and 3 types of the presmykayushchy are. Birds are presented by 241 look, among them such rare, as Sapsan, a black crane, a golden eagle, a black stork, a sea eagle-dolgokhvost, a sea eagle-belokhvost, etc.

The reserved mode has 40% of the territory of park, any economic and recreational activity is forbidden here. On park 5 pedestrian tourist routes among which the route is allocated for Markovo's mountain, the highest mountain top of Svyatoy Nos Peninsula are laid, the circular panorama to Ushkan Islands, northern part of the Chivyrkuysky gulf and sandy beaches of the Barguzin gulf from where opens.
