Saiga (Saiga tatarica) Facts for Kids


Did you know?
    The saiga is recognizable by an extremely unusual, over-sized, and flexible, nose structure. The nose is supposed to warm up the air in winter and filters out dust in summer.
  • Saiga are nomadic creatures that frequently cross borders of provinces and countries during their several-hundred-mile migrations to winter grazing areas.
  • Social structure. Saiga form herds of 30-40 animals.
  • Lifespan. 6 to 10 years.
  • Breeding. Gestation period is 140-150 days, with litter size 1-2. (A female saiga will begin breeding and give birth to her first calf by the time she’s a year old).
  • Diet. Grasses, steppe lichens, herbs and shrubs.
  • The saiga can migrate over distances of up to 1,000 kilometres between summer and winter.
  • Saiga herds once numbered in their millions, but the global population has declined rapidly to just thousands. (Poaching and habia loss)

The Magnificent Usyturt



The Ustyurt is a huge plateau within the Caspian watershed on the territory of Kazakhstan, Uzbekistan and NW Turkmenistan, covering an area of about 200,000 sq. km. It extends from Mangyshlak and Kara Bogaz Gol Bay in the west to the Aral Sea and Amu Darya delta in the east. The plateau rises above the plain to 350 meters, cut off from the surrounding plains by steep inaccessible ledges of the escarpment. To access from Nukus you travel north to Kungrad and then north west above the desert plain there suddenly rise sheer cliffs up to 400 m high called ‘chinks’ a steep pass allows access up onto the plateau. Its seminomadic population raises sheep, goats, and camels. The name is sometimes spelled Ust Urt.    

The Ustyurt Plateau, with its magnificent cliffs, escarpment, scenic canyons and outlying mountains, presents a unique landscape and has an exceptionally rich biological diversity. It has clay-sagebrush and saltwort-sagebrush desert plants, and in its south-eastern part of is clay-and-rock-debris, with alkali spots. The nature of the Ustyurt is fantastic and unique. Many animals that live there are listed in the Red Book of the International Union for Conservation of Nature (IUCN). It is especially beautiful in spring and autumn. Its summer temperature here is more than 50ºC, and often mirages appear in the scorching air. In in winter severe cold winter blows and it can reach 40ºC.  
 
For centuries, the Ustyurt Plateau has been a crossroads of civilizations (Scythians, Mongols and Kazakhs) and it has preserved traces of these many cultures.  Sensational historic discoveries have been made in recent years with more than 60 sites of the Neolithic period being found including the so-called Arana (Arrows), a complex configuration of hundred metres of stone fences which served for mass battue hunting of hoofed herd such as kulans, saiga antelopes and gazelles. 

The famous Silk Way passed through the plateau connecting Khiva with lower reaches of Emba and Volga. Along this trade route there was an ancient city called Shakhr-i-Vazir, Beleuli caravanserai, and Allan fortress. The ancient graveyards with the magnificent mausoleums called ‘mazars’ and other Islamic holy places are scattered across the plateau.

Catastrophic collapse of saiga population in Central Kazakhstan


In the northern summer a  catastrophic die-off  hit the largest population of the Critically Endangered saiga antelope Saiga tatarica located in central Kazakhstan. 

This virulent mysterious epizootic illness caused herd fatality of 100% once they were infected. It is estimated that more than 120,000 saiga were lost, some 40% of the species' total worldwide population of 250,000.

The deaths have been attributed to the Pasteurella bacterium an opportunistic pathogen that weakens the immune system.  It seems also likely that a number of environmental stress factors were involved that made the Saiga susceptible to the bacterium. An international team has been put together to investigate the deaths.

Northern Deserts of Central Asia

Introduction

The Central Asian Northern Deserts are a mosaic of clay, stone, salt and sand and together with the Central Asian southern desert, supports the highest level of biological richness of all Eurasian deserts. The region is populated by middle Asian and north Caucasus species and is closer in nature to the Turanian subtropical realm. The area is dominated by rarefied semi-shrub communities formed by the perennial saltworts (Chenopodiacea) and sagebrushes (Artemisia spp.). Northern Turanian or Kazakhstanian species of plants are the dominant flora. Two prominent small mammals in this eco-region are jerboa and gerbil. The latter digs deep burrows which become critical for vegetation growth. Rare but still found are the goitered gazelle, marbled polecat, saxaul jay, Asian desert sparrow, and Houbara bustard.

Location and General Description

Photo: Usturt Plateau

The Northern Desert includes the Kazakh territory of Mangyshlak, the central part of the Ustyurt plateau (including a large part of the territory of Karakalpakstan) streatching across again into Kazakhstan and the northern and southern areas near Balkhash Lake. The northern deserts are distinguished the following climatic parameters: total solar radiation 130-140 kilocalories (kkal) per square centimeter (cm2) and the radiating balance 45 - 50 kcal./cm2. The mean temperature in January is –10 to -15oC and in July from 24 to 26oC.

The precipitation is distributed evenly across seasons with some increase observed in the spring. The quantity of precipitation compounds 100-150 millimeters (mm) per one year (for separate years up to 200mm). The influence of the Asian anticyclone begins to develop in this territory.

The relief of the Northern Desert is varied in form and origin. Low littoral plains near the Caspian Sea, arid denudational plateaus (northern part of Ustyurt and western part of Betpakdala), stony plains, and melkosopochnik - a highly eroded plateau (Mangyshlak, eastern part of Betpakdala and northern part near Balkhash Lake) are represented here. There are also sandy deserts (Muyunkum), and sandy regions near the northern part of Aral Sea and near Balkhash Lake. These vast areas are composed of the clay alluvial and alluvial-delta plains found in the lower reaches of the Chu, Ili and Emba rivers.

Perennial saltworts predominate in the Northern deserts. Species that prevail on clay soils of the region include Anabasis salsa, Salsola orientalis, and sagebrushes such as artemisia terrae albae, A. turanica, and A. gurganica to the west. The plant communities from Salsola arbusculae formis and Nanophyton erinaceum are typical in stony soils. Typical for sandy soils are psammophitic semi-shrubs such as Ceratoides papposa, Artemisia terrae albae, var. massagetovii, A. santolina, and A. songarica, and shrubs such as Calligonum aphyllum, Ephedra lomatolepis and psammophitic grasses (Agropyron fragile).

The spring flora of ephemers and ephemeroids aren’t as richly represented in the northern desert as in the southern deserts, however the colorful tulips (Tulipa greigii, T. albertii) decorate these areas in some years. The halophytic succulent semi-shrubs such as Halimione verrucifera, Kalidium folitum, K. Schrenkianum, anc Halocnemum strobilaceum, and annual saltworts (species of Petrosimonia, Climacoptera, Suaeda) dominate on solonchaks. Spireanthus schrenkianus (relic of Tertiary time) is
a rare plant growing in the central area of Betpakdala. It is associated with a specific community of species peculiar to chink ecosystems found in Mangyshlak, Ustyurt Plateau, and Ili depressions.

Biodiversity Features

The most common northern desert mammals are the long-eared hedgehog (Erinaceus auritus), long-quilled hedgehog (Piracohinus hypomelas), and tolai hare (Lepus tolai). Yellow gopher (suslik) is characteristic of the clay desert and feeds on the ephemeral plants. A variety of rodents such as gerbils (Rhombomys, Meriones), and more than ten species of jerboas (Allactaga, Dipus, Paradipus, Eremodipus, Stylodipus) are found here. Both gerbils and jerboas play an important role in the biological functioning of the clay desert. Numerous, deep burrows by the gerbils are critical for vegetation growth. Both form a significant part of the diet of nocturnal predators such as owl, steppe ferret (Mustela eversmanni) and corsac fox (Vulpes corsac). Endemic jerboas include the selevinia (Selevinia betpakdalensis), comb-toed jerboa (Paradipus ctenodactylus), and the three-toed and five-toed dwarf jerboas (Salpingotus heptneri, salpingotus pallidus, Cardiocranius). Also endemic are representatives of several mammalian genera (e.g., Diplomesodon, Spermophilopsis, Pyderethmus, Allactodipus, Eremodipus).

Saiga (Saiga tatarica) were once quite common throughout these deserts, coming here for winter periods. Their population size has been significantly reduced however. The goitered gazelle or djeiran (Gazella subgutturosa subgutturosa) and marbled polecat (Vormela peregusna) are also rare and endangered. First attempts to reintroduce Asiatic wild ass (kulan) (Equus hemionus) were undertaken here in the 1980s. Until only recently, there was a chance that cheetah (Acinonyx jubatus) continued to survive in some parts of this ecoregion.

Larger birds of the ecoregion include the houbara bustard (Chlamydotis undulata), black-bellied and pin-tailed sandgrouse (Pterocles alcata, P. orientalis), cream-colored courser (Cursorius cursor), golden eagle (Aquila chrysaetus), short-toed eagle (Circaetus gallicus), steppe eagle, (Aquila rapax), Egyptian vulture (Neophron percnopterus), and saker falcon (Falco cherrug). Among the more common bird species are wheatears (Oenanthe isabellina, O. deserti), desert warbler (Sylvia nana), the desert lark (Ammomanes deserti), desert raven (Corvus ruficollis), and desert shrike (Lanius excubitor). Pander’s ground jay or saxaul jay (Podoces panderi) is a rare and unusual member of the crow family. Asian desert sparrow (Passer zarudnyi) is also rare. Houboara bustard is one of the most endangered bird species in this region. It migrates from Saudi Arabia through Iran and Pakistan to Uzbekistan, Kazakhstan, and Turkmenistan. It is threatened by elite hunters who spend large amounts of money for the opportunity to hunt it.

The list of desert reptiles includes a number of species of toad agamas, namely: Khentau toad agama (Phrynocephalus rossikowi), Molchanov's toad agama (P. moltschanovi), Strauch's toad agama (P. strauchi), spotted toad agama (P. maculatus), Sogdian toad agama (P. sogdianus), Said-Aliev's toad agama (P. helioscopus saidalievi). Other reptiles include gekkos (Alsophylax pipiens, A. laevis), Rustamov's skink gekko (Teratoscincus scincus rustamovi), Chernov's snake-lizard (Ophimorus chernovi), Ferghana sand lizard (Eremias scripta pherganensis), black-eyed lizard (Eremias nigrocellata), gray monitor (Varanus griseus), Afghan lytorhynch (Lytorhynchus ridgewayi), four-lined snake (Elaphe quatuorlineata), and the cobra (Naja naja oxiana). The invertebrate fauna of the sandy deserts is especially rich, represented by species such as grasshoppers, darkling beetles, scarabaeid beetles, butterflies, termites and ants.

The main anthropogenic threats are agriculture, hunting and poaching, and overuse of woody plants for firewood. Overgrazing of livestock is the main threat in non-irrigated areas. Biodiversity in the deserts of this region are adversely affected by desertification and localalised degradation of soils. Irrigated agriculture in marginal lands has significantly accelerated wind erosion and salinisation of soils.

Ustyurt Plateau - Saiga


The unique grassland steppe of the Ustyurt Plateau, a temperate desert lying between the Caspian and the Aral seas cover a vast area, about 200,000 square kilometers shared between Uzbekistan, Kazakhstan, and Turkmenistan.

The landscape is a mosaic of eroded hills, shallow basins, and extensive escarpments, with no permanent streams or open fresh-water sources.

With a high degree of endemism -- species that can only be found locally -- the plateau is home to vegetation types well-adapted to a harsh environment, including gypsum- and salt-tolerant plants.

Still found are ungulates like the goitered gazelle (Gazella subgutturosa subgutturosa) and the Ustyurt urial (Ovis vigneri arcal), as well as mammal predators such as the marbled polecat (Vormela peregusna).

The plateau's most famous resident is undoubtedly the saiga antelope (Saiga tatarica tatarica). With its bulbous, tubular nose and bulging eyes, the nomadic antelope is certainly one of the world's strangest-looking mammals. It's also on a list of critically endangered species by the International Union for the Conservation of Nature.

A range of human-related impacts are denuding and fragmenting the landscape and its habitats, affecting species' diversity, number, and migration. Meanwhile, social and economic difficulties have caused a sharp decline in funding for conservation efforts in a landscape susceptible to degradation and desertification.

In 1991, Uzbek authorities designated a protected area of 1,000,000 ha in Ustyurt to safeguard saiga lambing grounds. Likewise in Kazakhstan, the Ustyurt Nature Reserve protects 223,000 hectares of the plateau and in Turkmenistan's the 282,000-hectare Kaplankyr Nature Reserve covers the Ustyurt Plateau's southern spur.

The saiga population however has shrunk from more than 1 million in the 1990s to around 40,000 today. In particular the Ustyurt population is vulnerable, with less than 10,000 on the plateau with the population still in sharp decline.

As of today this species of ancient steppe antelope is represented by 5 dissociated groupings of 5-15 thousand of animal units each: Mongolian (in Mongo-lia), Kalmyk (in the Russian Federation), Urals (Kazakhstan), Usturt (Kazakhstan, Uzbekistan, Turkmenistan) and Turgai-Betpakdala (Kazakhstan), which keep decreasing by 20-40% per year. If this population decline rate is continued, then taking into account the biological peculiarities of this species (a number of natural enemies, climate effect, and susceptibility to diseases) and high demand for the products made of their horns one may talk about the complete loss of this species within next 5-7 years.

This unsustainable increase in poaching for Saiga is occurring because demand for its meat and very sadly for its antlers (used in traditional Chinese medicine as an alternative to the rhinoceros horn). The use of the antlers is totally unfounded and is not based on traditional Chinese medicinal practise at all, but on a combination of lots of greed (particularly that of the smugglers & other middle men) and way way too much money in the hands of too many backward and superstition people living in China, Taiwan, Hong Kong and other parts of the far east who are buying at very high prices antlers & antler preparations which have historically have NEVER ever been used in any traditional Chinese medicinal preparations.

The saiga will face extinction unless very strong conservation measures in Central Asia and the Russian Federation are put in place and efforts by the Chinese/ Taiwan / Kong Kong governments ect. are steeped up considerably ie. making a real effort to stop the sale of the antlers and other by-products of the Saiga and prosecuting whomever is involved (as was done to save the panda in the PRC).
