The reserve, a wintering place for migratory birds, is the richest nature reserve in Russia in terms of the number of species - over 300 species have been recorded in the reserve, its buffer zones and subordinate reserves. The reserve is part of several "Important Bird and Biodiversity Areas" (IBAs). The Sarykum sand dune is the highest sand dune in Europe, at {{convert|262|m|ft|abbr=on}}. The reserve is situated in the Tarumovsky District of Dagestan.[1][2] TopographyThe Dagestan Reserve sits on the northwest coast of the Caspian Sea, at the mouth of the Kuma River as it empties into Kizlyar Bay. The reserve covers the low, marshy wetlands of the Kuma delta, as well as the entirety of Kizlar Bay. Tyuleniy Island lies to the east of the reserve, {{convert|43|km|mi|abbr=on}} from the coast, just outside of the bay. To the north the landscape changes to semi-desert.[1] The reserve includes four sectors that are disconnected from the Kizlar Bay territory:
Climate and ecoregionDagestan is located in the Caspian lowland desert ecoregion. This ecoregion covers the coastal desert - sand dunes, salt deserts, solonchaks (shors) and clay deserts (takyrs) - on the north and east shores of the Caspian Sea. Vegetation is sparse, but highly specialized with mostly halophytes (salt-tolerant plants), shrubs and semi-shrubs.[3] The climate of Dagestan is Humid continental climate, cool summer (Köppen climate classification (Dwb)). This climate is characterized by high variation in temperature, both daily and seasonally; with dry winters and cool summers. The strong heating of the sand on Sarykoum, the dune reaches temperatures of {{convert|55|-|60|C|F|abbr=on}} in the summer. The average temperature in January is {{convert|-1|C|F|abbr=on}}; in August it is {{convert|+31|C|F|abbr=on}} degrees. Average annual rainfall is {{convert|336|mm|in}}.[4][5] Flora and faunaThe plants of the wetlands are mostly reeds with a height of {{convert|1.5|–|3|m|ft}}. The meadows on drier ground are grasses and sedges. Desert vegetations is represented by saltwort, sagerush-saltwort, wormwood. In the reedlands, the mammals include wild boar, muskrat, nutria, and water rat. On the steppes are hare, fox, and wolf.[2] The main focus of the reserve is the birdlife, particularly waterfowl. The boundaries of the main reserve area of the Kuma Delta includes three "Important Bird and Biodiversity Areas" (IBAs) as defined by Birdlife International: "Nizhnekumiskiye floodplains (along the mouth of the Kuma in an area that is about half desert and half riverine grasslands), "Kizlar Bay" (which is about 90% marine, and 10% humid grassland), and "Tyuleni Island" (which is itself mostly wetlands, mudflats, and shingle/stony beach).[6] Notable species include the vulnerable Dalmatian pelican, one of the largest birds, with a {{convert|10|ft|m|adj=on}} wingspan. On the salt marshes are ibis, herons, terns, stilts, curlew and other waders. During the migrations on the west coast of the Caspian are large numbers of cormorants, grebes, ducks, geese and gulls. Ecoeducation and accessAs a strict nature reserve, the Dagestan Reserve is mostly closed to the general public, although scientists and those with 'environmental education' purposes can make arrangements with park management for visits. Excursions can be arranged by the public. but permits must be obtained in advance. The main office is in the city of Makhachkala.[1] See also
