  • The Kerzhensky Nature Reserve is a part of the Kamskoye-Bakaldinskoye bogs Important Bird and Biodiversity Area (IBA) with the area of 3159.85 square kilometers. The Kamskoye-Bakaldinskoye bogs IBA covers the northern (Trans-Volga) part of the Lyskovo and Vorotynets districts, as well as the adjacent territories of the Bor, Semyonov and Voskresenskoye districts. Osprey, golden eagle, greater spotted eagle, common curlew, whimbrel, Eurasian oystercatcher, great grey shrike, and other rare bird species nest here. Cranes nest in cranberry bogs, while kingfishers nest on the banks of the Kerzhents River.

    The Kerzhensky Nature Reserve is a part of the Kamskoye-Bakaldinskoye bogs Important Bird and Biodiversity Area (IBA) with the area of 3159.85 square kilometers.

    The Kamskoye-Bakaldinskoye bogs IBA covers the northern (Trans-Volga) part of the Lyskovo and Vorotynets districts, as well as the adjacent territories of the Bor, Semyonov and Voskresenskoye districts.

    A total of 85 IBAs were registered in the Nizhny Novgorod Region. Of these, 14 are international (global), 14 are international (European), 2 are probably international, 47 are regional, and 8 are probably regional (Picture 1).

    The Important Bird and Biodiversity Area (IBA) is an area that is a place of concentration of one or more bird species during nesting, moulting, wintering, or resting during migrations. These are the most valuable areas of the ground or water surface for birds, the degradation of which severely affects the condition of the population of one or more bird species. These are "nodal points" which create a resemblance of a power frame of the habitat, preserving which, it is possible to save the species from extinction even in conditions of strong anthropogenic influence.



    The IBA concept was developed by the International Bird Conservation Council (ICBP, now BirdLife International) in the 1980s. The Russian Bird Conservation Union is working to detect and determine IBAs in the vast territory of our homeland, which resulted in the reference book "Key Bird Areas of Russia", Moscow, Russian Bird Conservation Union, 2000.

    The programme "Key Bird Areas of Russia" is aimed at promoting voluntary participation of all those who consider it important and necessary to search and preserve valuable areas for birds.

    The main tasks of the IBA programme:
    1) detection and description of the key ornithological areas of Russia;
    2) arrangement of the IBA protection;
    3) monitoring the status of the IBA: control over the preservation of habitats and welfare of the species inhabiting the area;
    4) taking measures in case of the IBA and bird threats;
    5) promotion of bird preservation and bird habitat protection;
    6) preparation and publication of IBA catalogues to disseminate information on key bird areas to the public, as well as to authorities and management structures.

    The Kamskoye-Bakaldinskoye bogs are the largest bogs in the Volga River basin which have survived in their natural state as an array of raised bogs, transitional bogs, and lowland bogs. The total area of explored peat deposits is about 70 thousand hectares. Most of the bogs here are transitional, among them there are open sedge and sphagnum, cottongrass and sphagnum, scheuchzeria and sphagnum, as well as raised bogs with a stand of low-throat pine and birch, there are raised bogs with a stand of low-throat pine. In the floodplains of small rivers, along the margins of raised and transitional bogs, small areas are occupied by lowland bogs that are forested (birch and black-alder) and open (reed and sedge). 2000 ha of bogs are milled. Among the bogs there are 27 lakes of aeolian origin, many small rivers and streams. Most of the area between bogs is occupied by 15-50-year-old birch and aspen trees at the site of felling and burning, and pine forests not touched by cutting at the age of 100-120 years have survived only in the form of small manes among the least accessible for people and bog vehicles. The IBA includes a section of the Cheboksary reservoir.

    The main habitat types found in the territory are: pine forests with 38%; secondary mixed and small-leaved forests with 30%; freshwater lakes with 1%; water area of the Cheboksary reservoir with 5%; raised, transitional, and lowland bogs with 23%; arable lands with 1%; deposits with 1%; settlements with 1%.

    The IBA serves as a habitat for animals, and plants, and fungi listed in the Red Data Book of the Russian Federation: Apollo, clouded Apollo, narrow-leaved marsh orchid, red helleborine, rein orchis, chestnut bolete, bluing bolet, coral tooth fungus, white aspen, violet webcap, tree lungwort, brown long-eared bat, Brandt's bat, pond bat, сommon noctule, parti-coloured bat, Nathusius's pipistrelle, otter, forest dormouse, common European adder, smooth snake, hummingbird hawk-moth, scarce swallowtail, Old World swallowtail, small emperor moth, dark crimson underwing, Catocala pacta, purple emperor, Bombus subbaicalensis, large carder bee, Bombus serrisquama, Bombus schrencki, Camponotus fallax, Formica lugubris, Amazon ants, Heterocope borealis, cladoceran, fishing spider, mountain birch, Sparganium gramineum, Sparganium angustifolium, Botrychium multifidum, Botrychium lunaria, Salix lapponum, Salix myrtilloides, Oxycoccus microcarpus, Corallorrhiza trifida, Leersia oryzoides, Sempervivum soboliferum, Carex dioica, Carex pauciflora, Carex chordorrhiza, Listera cordata, Pedicularis sceptrum-carolinum, Potamogeton trichoides, Potamogeton praelongus, Drosera anglica, Hepatica nobilis, Glyceria lithuanica, Galium triflorum, Huperzia selago, Lycopodiella inundata, Menegazzia terebrata.

    The lands of specially protected natural areas (the Kerzhensky Nature Reserve) occupy about 15% of the territory.

    The lands of the forest fund occupy 77% of the territory and belong to the state forest fund of the Semyonov, Voskresenskoye, Zatonskoye, Lyskovo, and Mikhailovskoye leskhozes, as well as to the forests of agricultural enterprises, united in the Bor interfarm forestry and not united in the interfarm forestry in the Lyskovo and Vorotynets districts. Except for protected areas, forests are subject to a full range of forest management measures, including clearcuts and selective logging, planned by the forest management organization. The water area of the Cheboksary reservoir occupies 5% of the area, agricultural lands (arable land, deposits, hayfields, pastures) occupy about 2%, and lands of settlements occupy about 1%.

    Available information on the number of bird species meeting the criteria for the identification of IBAs of different significance is presented in the table below.

    The IBA is of global importance according to criterion A3: 6 species nest there, the distribution of which is limited by taiga biome (red-neck grebes, bullfinch, big greenshank, bearded eggnut, finch, oatmeal-cut).

    In recent years, there has been an increase (restoration of the optimal level) in the number of rare species of birds of prey due to biotechnical measures taken. The number of grey cranes has stabilized after a period of growth in the 1980s and 1990s. In 2003, a significant decrease in the number of common curlews (3-4 times as compared to 1988) was observed. The reasons for the decrease are unknown and apparently not related to the status of the IBA. In 2003, for the first time in the Nizhny Novgorod region, nesting of whimbrel (in the Kerzhensky Reserve) was observed. In addition to being important for many rare nesting bird species, the Kamskoye-Bakaldinskoye bogs serve as stopovers for waterfowl and near-water birds, but there is no accurate census of bird populations at the bay.

    Threats of degradation of the area as an IBA are as follows: high degree of threat due to selective logging and development of the area's infrastructure; average degree of threat due to continuous logging, recreational load, anxiety factor, and forest fires.

    Different indicators of the condition of the IBA show signs of both improvement and deterioration of the situation; in the long run, a significant deterioration is possible due to the growth of recreational load.

    Currently, the greatest threat is posed by clearcuts and selective logging in water protection zones of bogs (including sanitary logging in protected areas of natural monuments), as well as forest fires. Due to insufficient budget financing of forestry enterprises they are forced to earn their own money by selling timber from felling of intermediate use. This lack of funds does not allow forestry enterprises to carry out prompt identification and extinguishing of fire sources at a sufficiently high level.

    The Kamskoye peat enterprise currently exists, but peat is not being developed. The previously developed and dried area (2770 ha) has not expanded. The likelihood of resuming peat extraction is low.

    The most significant negative factor in the near future may be a high recreational load. Availability and visitor numbers in the area are increasing rapidly due to the construction of new asphalt roads. Increased traffic leads to an increase in the number of fires and poachers, as well as an increase in the impact of disturbance on nesting birds.

    A possible rise in the level of the Cheboksary reservoir from the existing 63 m level to 65 m or 68 m would result in a significant disturbance of the hydrological regime of the area, which would result in the drying up of forest areas due to waterlogging and the restructuring of wetland and aquatic ecosystems. The reference value of wetland ecosystems will be lost, and many local populations of rare species of living organisms will be reduced or disappear.

    The Kamskoye-Bakaldinskoye group of wetlands is included in the list of wetlands of international importance under the Ramsar Convention. The Kerzhensky State Natural Biosphere Reserve (467.86 km2) has been established in the IBA, 17 natural monuments with a total area of 877.22 km2 ("Krasnoe Lake", "Maloye Plotovo Lake", Lake Ryzhan", "Swamp of Light", "Swamp of Light", "Swamp of Light", "Swamp of Deryabinskoye and Lake Deryabino", "Swamp of Bakaldinskoye", "Swamp of Ryabinovskoye with Ryabinovskoye lake", "Swamp of Slonovsko-Kurmanovskoye with M. Kultey", "Lake B. Kultey", "Bolshoye Palniki Bog", "Plotovskoye Bog with Lake B. Plotovo", "Kama-Osinovye Kotly Swamp", "Dryanichnoye Swamp", "Floodplain oak wood at the v. Penyaksha", "Pine forest area with young run-of-river at the v. Makar'evo", "Geographical forest cultures of M.G.Zdorika") are in the natural complex reserve "Lamnensky". A total of 58% of the IBAs are protected.

    The Nizhny Novgorod Trans-Volga Biosphere Reserve, the functional center of which is the Kerzhensky Reserve, received a UNESCO certificate from 16.12.2002. Currently, the reserve, with the involvement of all interested organizations, prepares management and development plans for the biosphere reserve. It is planned to include the entire territory of the Kamskoye-Bakaldinskoye wetland group (including the Kerzhensky State Nature Reserve) in the interaction zone of the biosphere reserve. The project for the organization of the Lake Bright and Adjacent Bog Massif Nature Monument (area of 4572.1 hectares, protected area of 3402.5 hectares) has been drawn up, including the existing nature monuments Lake Svetloye and the Bog Svetloye. The documentation has been approved by the local authorities of Voskresenskoye district.

    A regulation on the Kamskoye-Bakaldinskoye group of bogs is being drawn up and it will be protected with the status of a "protected landscape area".
