The Kizlyar Bay of the Caspian Sea, with its rich coastal marine
resources, attracts more than 100 species of birds. The
section of the bay protected in the zapovednik is an especially
important thoroughfare for migration of waterfowl en route between
nesting and wintering areas in the spring and fall. Many
migratory birds linger in the rich feeding grounds for long periods
and a number of species spend the entire winter here. Large
colonies of common coots (Fulica atra), glossy ibises
(Plegadis falcinellus), and Eurasian spoonbills (Platalea
leucorodia) flock to the bay to nest. Herons (Egretta
garzetta, E. alba, Ardea cinerea) and greylag geese (Anser
anser) nest in significant numbers along the reed-rimmed
coast. Several pairs of mute swans (Cygnus olor)
have been found nesting on small islands in the bay. The
voices of numerous species of gulls, including black-headed and
herring gulls (Larus ridibundus, L. argentatus), blend
in a cacophonic symphony over the water. Migrating great
cormorants (Phalacrocorax carbo), pintail (Anas
acuta), and great crested grebe (Podiceps cristatus)
gather here in large numbers. Several rare and endangered
bird species have been recorded in the zapovednik, including
Dalmatian and eastern white pelicans (Pelecanus crispus,
P. onocrotalus), greater flamingo (Phoenicopterus ruber),
little bustard (Tetrax tetrax), and great bustard (Otis
tarda).
Kizlyar Bay is an important spawning ground for a number of
commercial fish species such as sprat (Clupeonella delicatula
caspia), pike-perch (Esox lucius), herring (Alosa
saposhnikovi, A. brashnikovi), oriental bream (Abramis
brama orientalis), common carp (Cyprinus carpio),
Caspian roach (Rutilus rutilus caspicus), and other
species, many of which are also important components in marine
and freshwater food chains. Approximately 75 million juvenile
freshwater and anadromous fish are spawned here each year, all
in an area of about five square kilometers. Many species
have adapted their spawning habits to the changing water levels
of the Caspian. When the water level is high they spawn
along the coast; when the water recedes they spawn in areas of
open water on pondweed (Potamogeton spp.) and other
vegetation growing at depths of several meters. The aquatic
area of the zapovednik also serves as an important feeding and
wintering ground for many species of fish, and is a vital route
for fish migrating along the Caspian coast. Sturgeon species
(Acipenser guldenstadti, A. stellatus, A. nudiventris, A.
ruthenus, Huso huso), highly valued around the world for
their black caviar, pass through the reserve, though none spawn
here. Altogether, over 70 species and subspecies of fish
rely on the marine protected area for feeding, spawning, and
wintering.
Mammals frequenting the thick belt of reeds along the shore
of Kizlyar Bay include wild boar (Sus scrofa), jungle
cat (Felis chaus), and the introduced raccoon dog (Nyctereutes
procynonoides), muskrat (Ondatra zibethicus), and
swamp beaver (Myocastor coypus). Corsac and red
fox (Vulpes corsac, V. vulpes) and European hare (Lepus
europaeus) inhabit steppe lands near the coast. The
marsh frog (Rana ridibunda) is the only amphibian found
in this section of the reserve. Reptiles include Renard's
viper (Vipera ursini), grass snake (Natrix natrix),
and the endangered spur-thighed tortoise (Testudo graeca).
Nearly
180 km to the south, the Sarykum Sand Dune section of the zapovednik
offers strikingly different scenery and wildlife. The
dune, looming 262 meters above the adjacent Caspian lowlands, is
dominated by desert and semi-desert habitats. Here, long-eared
hedgehog (Erinaceus auritus), northern three-toed jerboa
(Dipus sagitta), gray hamster (Cricetulus migratorius),
and corsac fox are among the more common mammal residents. Bird
life is significantly less diverse on the dune than in Kizlyar
Bay. European nightjar (Caprimulgus europaeus) make
sparse nests on the sand. Lesser kestrels (Falco naumanni)
and harriers (Circus aeruginosus, C. pygargus) keep watch
for small reptiles as they soar above the dune, while large cinereous
vultures (Aegypius monachus) circle high in the sky for
hours on motionless wings. Eurasian rollers (Coracias
garrulus) take advantage of the abundance of insects and lizards
and, occasionally, flocks of European and blue-cheeked bee-eaters
(Merops apiaster, M. superciliosus) linger here. Sarykum
Sand Dune is the preferred habitat of a number of reptiles: toad-headed
agama (Phrynocephalus mystaceus) and rapid fringe-toed
lizard (Eremias velox) are relict species found on the
dune. Blunt-nosed viper (Vipera lebetina) inhabits
the foot of the dune, along with Northern viper (V. berus),
sand boa (Eryx miliaris), and large whip snake and Dahl's
whip snake (Coluber jugularis, C. najadum). Green
toads (Bufo viridis) are the most prevalent amphibian
on the dune. Invertebrate life in both sections of the zapovednik
has been poorly studied. |
Vegetation
|
Coastal lowland valleys with a number of inlets flank the Kizlyar
Bay section of Dagestansky Zapovednik. The lowlands, which
lie 28 meters below sea level, once lay at the bottom of the
now diminished Caspian Sea. Plant communities shift from
desert and semi-desert vegetation inland to salt marsh, meadow-bog,
and wetland ecosystems on the coast. Rich marine vegetation
and thick underwater meadows blanket the shallow sea floor. Representatives
of desert plant communities inland include frosted orach (Atriplex
tatarica), sea-blite (Suaeda confusa), giant alkali
grass (Puccinella gigantea), and Gmelini's leadwort
(Limonium gmelinii). Semi-desert vegetation covers
a limited area, but includes bulbous bluegrass (Poa bulbosa),
clasping pepperweed (Lepidium perfoliatum), feathergrass
(Stipa capillata), and wormwood (Artemesia lerchiana). Meadow-bog
communities along the coast consist of broad belts of tall bur
reeds (Phragmites communis), woodreeds (Calamagrostis
epigeios), water mint (Mentha aquatica), and spiked
loosestrife (Lythrum salicaria). Narrow-leaved
cat's tail (Typha angustifolia), bur reed, and common
club rush (Scirpus lacustris) rim the shore. Sea
club-rush (Bolboschoenus maritimus) flourishes in shallow
waters. Further offshore, dense underwater meadows, which
often blanket the sea floor completely, consist mostly of fennel-leaved
pondweed (Potamogeton pectinatus) and, in deeper waters,
also curly-leaved pondweed (P. crispus) and water milfoils
(Myriophyllum spicatum, M. verticillatum). Common
floating pondweed (P. natans) and star duckweed (Lemna
trisulca) float on the surface. Rare plant species
in the Kizlyar Bay section include water chestnut (Trapa
natans), great fen-sedge (Cladium mariscus), floating
fern (Salvinia natans), and common bladderwort (Utricularia
vulgaris) -- the flowering stems of which rise above the
water.
The Sarykum Sand Dune, a miniature desert island amidst a
sea of steppe, hosts a vastly different array of vegetation. The
plant life on the dune has been well documented, starting from
the observations of Soviet botanist A. Maiorov in the 1920s. Today,
the list of plants here includes 279 species. An entire order
of plant forms was discovered in the sands, including Karakugen
milkvetch (Astragalus karakugensi) and the eremosparton
shrub (Eremosparton aphyllum) -- plants that are characteristic
of the deserts of Kazakhstan and Central Asia. Maiorov concluded
that these are relict species remaining from an ancient desert
that once extended over a large area. The top of the dune
is virtually bare of vegetation due to the continuous movements
of blowing sand. Lower down, the first plants to take hold
in the sands are wormwood (Artemisia arenaria), giant
wild rye (Leymus giganteus), and ghost orchid (Epipogium
aphyllum). These plants are soon joined by oriental
bugseed (Corispermum orientate), Colkhic sedge (Carex
colchica), and annual kochia (Kochia laniflora). Siberian
wheatgrass (Agropyron sibirica), drooping brome
(Bromus tectorum), and bulbous bluegrass grow on less
dense sands, as well as sea grape (Ephedra distachya)
-- the only evergreen found here. There are a number of mineral
springs and swampy areas at the foot of the dune, due to the fact
that the mountain of sand absorbs large quantities of moisture
from the air. Here bur reed, willows (Salix spp.),
black poplar (Populus nigra), and other water-tolerant
species are found. Among rare species on the dune are sharp-lobed
iris (Iris acutiloba), Shishkin's groundsel (Senecio
schischkinii), and Karakugen milkvetch.

Geographical Features

|
Dagestansky Zapovednik is situated on two territories in the
Dagestan Republic of Russia's North Caucasus Region. The
Kizlyar Bay section of the reserve in the Tarumovsky District,
which includes predominately coastal and marine habitat, covers
18,485 km and has a buffer zone of 19,890 km extending along
its western and southern borders. The Sarykum Sand Dune,
located 180 km to the south of Kizlyar Bay in the Buinaksky District
(and under 25 km from the capital city of Makhachkala), covers
576 ha. Its buffer zone includes a one-kilometer wide strip
of 1,175 ha around the core of the protected area.
The Sarykum Sand Dune is a unique natural phenomenon -- a virtual
island of desert amid of sea of steppe habitat. The sand
dune represents one of the last fragments of Asian desert that
has been preserved west of the Caspian and is the largest such
formation in all of Eurasia. The southern flank of the
dune connects with the foothills of the Kumtorkalinsky Range,
while the northern and eastern sides gradually slope down to
the lowlands along the Caspian. Sarykum, which reaches
262 meters above sea level, is the highest of a 3,000 ha (30
km2) system of sand dunes. The system gradually formed
over the ages as a result of wind erosion of sands from neighboring
mountains and sediments of ancient terraces of the Caspian Sea. Sarykum
in the Tartar language means "golden sands." The loose
sands on the upper parts of the golden dune are constantly in
motion, stirred by strong winds blowing from the west and northwest
in winter and east and southeast in summer.
The
climate along the northwestern Caspian coast is affected by both
marine and continental weather systems. Most of the precipitation
(averaging 366 mm annually) falls from September to November. In
Kizlyar Bay, temperatures soar to 35 degrees Celsius in July,
while dipping to --35 degrees Celsius in January. Winds,
prevailing from the east and southeast, frequently make for rough
waters in the bay. The climate around Sarykum to the south
is dry and warm, with the highest average temperatures (31.4
degrees Celcius) noted in August and the lowest average temperatures
(--1 degrees Celcius) occurring in February.
While there are no
rivers in the Kizlyar Bay section of zapovednik, the Kuma River
flows into a narrow inlet just north of the reserve's boundary. The salinity of Kizlyar Bay is dependent on waters
flowing from the Kuma, the Volga, and less so from the Terek River,
as well as wind patterns impacting marine currents and mixing in
the water column. The Shura-Ozen River flows through the
Sarykum section of the zapovednik, beginning on the slopes of the
Gimrinsky Range and flowing into the Caspian. |
Conservation Status

The original plan for creating Dagestansky Zapovednik, drafted
in the 1970s, called for setting aside five different territories
with a combined area of 111,000 ha (1,110 km2), or five times
the current size of the reserve. Due to a number of complications
-- from the failure to obtain agreement from landusers to deterioration
of ecological conditions in the proposed areas, only two regions
were included in the zapovednik when it was finally created in
1987 -- Kizlyar Bay and the Sarykum Sand Dune. With a combined
area of 19,061 ha (191 km2), the current territory of the zapovednik
protects less than 0.19 percent of Dagestan and includes none
of the spectacular high mountain landscapes of the Great Caucasus
Range, occupying much of the southern part of the republic. High
mountain areas of the Guton Mountain Range and the lower reaches
of the Samur River still require protection. Efforts are
underway to create the Upper Inkhelinsky Section of the zapovednik
in the Akhvakhsky District. Additionally, initial approval
has been granted by the Kizlyar District Government to set aside
over 100 ha of reasonably intact forest habitat along the coast,
as well as part of Tuleny (Seal) Island in the bay for conservation
of rare species of plants and animals.
One of the greatest problems for conservation of Dagestansky
Zapovednik is rampant poaching of rich fish resources in Kizlyar
Bay. Kizlyar Bay is the main commercial fishing region
along Dagestan's Caspian coast. Poaching impacts populations
of spawning species, particularly carp and other large fish. Sturgeon
have virtually disappeared from the bay area altogether. Poaching
in fish wintering grounds markedly affects regeneration of a
number of species. The fight against poaching is complicated
by the fact that the poachers are usually better equipped than
the reserve rangers. Some poachers even operate within
the state fish inspection agency. One way to help deter
poachers would be to place sizable marine buoys around the perimeter
of the marine area to make the borders of the reserve visible. More
radical measures are needed to halt poaching by enforcement agencies.
Human pressures also threaten the integrity of the fragile Sarykum
Sand Dune ecosystem. People in neighboring villages
use lands in the dune's buffer zone for farming and livestock. Industrial
enterprises extract sand from areas adjacent to the buffer zone.
