Polistovo-Lovatskaya array is located in the center of a vast lowland Priilmenskaya situated among Devonian lowlands. Lowland has a general tendency towards the north-northeast to the Ilmen basin. This bias Lovat River and its Tributaries & mdash; Redya River, Porus, Polist flow in the north-north-east almost parallel to each other.
One of the largest lowland swamps Priilmenskaya is Polistovo-Lovatskaya array. He MNV. The absolute marks of the surface varies between 98 and 100. 67 m.The relief-Polistovo Lovatskaya bololotnogo array is a group of individual elongated depressions and troughs, between which the elevated ridges and low plateau.
Among the moor there are several ridges extending from the southwest to the northeast; higher parts protrude above the surface of the peat in the form of islands in the chain; Other, lower entirely hidden under peat. The positive relief forms are still eskers, elongated in the direction of south-west & mdash; north-north-east.
Polistovo-horse Lovatskaya raised bog system is located in the northwest of the European part of Russia, on the border of Novgorod and Pskov regions.
In 1994, the territory of the bog arranged two specially protected natural territories of federal value with very strict regime of protection: Reserve «Rdeysky» in the Novgorod region Reserve «Polistovsky» in the Pskov region.
Federal State Institution State Natural Reserve «Rdeysky» instituted by the Russian Federation Government dated May 25, 1994 The reserve is located in the Novgorod region within the Kholmsk and Poddorsky District.
Reserve stretches from north to south and 42 km from east to west – 25 km.
The administration and the central manor of ILI «Rdeysky» Hill is located in the Novgorod region, 200 km south-south-west of the city of Novgorod the Great.
State Natural Reserve «Rdeysky» It guards the eastern part Polistovo-Lovatskaya bog. 80% of the area of the reserve is occupied by marshes, they are very vulnerable — Any minor anthropogenic load has a significant impact on vegetation, soil, localization and path of movement of wild animals and birds nesting sites; a further increase in anthropogenic pressure can lead to the degradation of wetland ecosystems. In this regard, strict adherence to the protected mode, it becomes a necessary measure for the preservation of nature Rdeysky marshes.
The swamps are extreme ecosystems, where many environmental factors: the hydrological regime; climate; edaphic conditions (lack of shelters, limiting the possibility of digging holes because of the high groundwater level and the presence of perched water after floods and & nbsp; during floods); monotonous food resources and & nbsp; may be limited in certain periods. For this reason the Reserve has no autonomous mammal populations, it is only seasonal reserve. The exceptions are small mammals that populate the island vnutribolotnye constantly. But the level of species diversity of those communities is small, due to the small size of the islands and the adverse influence of weather factors. With marsh system and mineral forest islands are permanently linked 14 species of small mammals from the orders of rodents and insectivores (bat plain, common shrew Small shrew average, shrew common, shrew ordinary, beaver, voles red and red, root vole, vole common, vole dark , Eurasian harvest mouse, field mouse, yellow-necked mouse). Other species appear here when mitigated the negative impact of environmental factors, or when the quality of «lives» by some factor in the reserve than in peripaludal habitats.
Of the 38 species found in the reserve, to numerous species belong to six (hare, otter, water vole and red, common shrew). They constitute 15.8% of the species of the reserve. The largest group consists of «normal» kinds.
A substantial proportion of rare species. These include the hedgehog, weasel, hare, squirrel, dormouse forest, forest birch mouse, vole ordinary, wood mouse, badger, polecat forest, deer, muskrat.
With the help of biotechnological activities supported locally high density of wild boar. Mixing old-growth forests and replacing them with small-leaved derivatives negative impact on the state of populations of squirrels and flying squirrels.
bog – the whole world, special and unique. It is difficult to find in our area other such terrain, where the world of birds would be just as unique and original.
Here is shelter to many rare and endangered species in the marshes Rdeysky. For protected areas little exploited by man, and large predators come here too often. Some of the rare species of birds such as the golden eagle, previously lived in different lands, but now preserved only in the marshes.
In addition, only here we encounter a number of northern species of birds, which resembles the usual bog tundra. Among them, ptarmigan, black-throated diver, golden plover.
Mineral island found in the marsh, to ensure the presence of forest species: blackbirds and woodpeckers, titmice and finches, robins and wrens.
A lot of rivers and lakes provide habitat for waterfowl: mallards, teals and other birds.
It is surprising that some species of birds, nesting usually only near human habitation, also mastered the bogs. These birds include the starling, hoodie and common swift. The variety of the feathered inhabitants impressive. But now we look at a swamp in the spring or summer when the birds are relatively large. In the winter time it is deserted. Only occasionally can be seen flocks of grouse that migrate, adhering to the forest outskirts bog. Willow Grouse also avoid the central portions of the swamp, where they have nothing to feed on.
Now they try to stay near the shrubs, where you can eat willow buds. In forest islands became very quiet, and only occasionally you can hear the squeak of willow tit and the woodpecker tapping. From passerine in the swamp you'll find most of the forest ridge and Finch, as well as whinchat Ordinary Shrike.
Charadriiformes – true children of the marshes. Among them, of course, sandpipers, large and Whimbrel, Greenshank, Wood Sandpiper, godwit, snipe, Chernyshev, as well as the golden plover and lapwing.
Waterfowl inhabiting the marshy ponds – This, basically, dabbling and diving ducks: mallard, teal – Teal and Garganey, Goldeneye, Tufted Duck. Remarkable, however, is the fact of breeding ponds on Rdeysky reserve whooper swan.
