Background to the projects
The steppes of Mongolia
Mongolia is a very big country. It has been assumed that it has the richest unexplored natural resources in the world. It is also very sparsely populated: twenty-five percent of its only 2,2 million inhabitants live in the capital Ulaanbaatar. The remaining population is scattered over a limited number of villages and towns. Most of them, however, are nomadic herdsmen who seasonally wander with their families and livestock from one pastoral area to the other.
Only Mongolia still has extended areas with undisturbed steppes. There one can find the highly valuable grassy mountain steppes and the arid steppes.
Unfortunately even in this country these pristine steppes are being threatened. The major source of the national income is cattle breeding. The present thirty-eight million head of cattle are a very heavy burden on the carrying capacity of the steppe.
Successively wild grazers such as wild sheep, wild goats, gazelles and the wild horses had to make way for their domestic congenitors. The wild horse even became completely extinct from the wild in the late 1960s.
Przewalski's horse, the last wild forebear of the domestic horse: a threatened species
The last Przewalski horses in the wild were seen in 1968. That was in the area in which this species, that once spread over the entire Eurasian continent, had found its last refuge, the Tachyn Schar Nuruu in the Southwest on the border with China. It is certain that the species has become extinct from the wild.
Around 1900 a small number of Przewalski horses was caught from the wild; fifty-three of them did found their way to public and private zoos and wildlife parks all over the world. Today there are some 1,600 of them living in captivity. All of them descending from only thirteen wild caught forebears. Without introduction of fresh blood this lasted for thirteen to fifteen generations. Protracted captivity causes in wild animals a serious violation of their innate social behaviour patterns; the effects of the so-called "creeping domestication" are undeniable.
Evidently it is very difficult to reintroduce them directly from captivity into the wild without risking high losses. To overcome this dilemma the Foundation Reserves Przewalski Horse (FRPH) founded six so-called semi-reserves in the Netherlands and in Germany. In these semi-reserves, measuring from thirty to 256 ha., groups of Przewalski horses were able to live according to their inborn instincts in social groups. Together these groups built up a depot of which a healthy and viable progeny, has a great chance to live sustainably in Mongolia. All of these descendants in Hustai have a low inbreeding coefficient and all of them together are genetically very diverse.
Reintroduction, habitat selection and feasibility studies
In 1988 the joint Russian and Mongolian Biological expeditions inspected fifteen areas in Central Asia and Mongolia on their suitability for reintroduction of Przewalski into the wild. It soon became clear that the pristine grasslands of Central Asia belonged to the most threatened ecosystems of the region.
Finally an area some 120 kilometres from the Mongolian capital Ulaanbaatar was chosen as the most suitable for the reintroduction and establishment of a free roaming Przewalski population. This area, Hustain Nuruu, already had a long history as a protected region: first as the exclusive shooting ground of the last Khan and thereafter as pastoral reserve for the local people.
Przewalski horses return to Mongolia
In 1990 the Mongolian Association for Conservation of Nature and Environment (MACNE), the FRPH, the governor of the Central Aimak (province) that owned the Hustai area, and a few other organisations signed an agreement to co-operate. On March 2nd 1991 the Parliament of Mongolia ratified the project. The Mongolian themselves were also very eager to welcome back their "takh" as is the name for "wild horse" in Mongolian. When on July 5th 1992 the first flight of sixteen horses landed at the airport of Ulaanbaatar hundreds of people came to welcome them.
FRPH and MACNE are both responsible for the execution of two projects:
Building up a free roaming Przewalski population not only benefits this threatened species, but is also a enormous stimulus for the recovery of the original biodiversity of the steppe.
In November 1993 the Mongolian parliament granted Hustai the status of reserve and in 1997 this status was augmented to that of National Park. Little by little a legislation concerning the protection of the indigenous plant and animal wildlife was constructed. In the spring of 1994 parliament accorded this law. In 1997 the status of the park was upgraded till National Park. In December 2002 the UNESCO enlisted Hustai National Park as Man and Biosphere Reserve.
Steadily the nomads and their livestock had to leave the 50,000 ha. large national park. Hunting and poaching are forbidden. At present the area is totally free from livestock.
Only when extremely bad conditions occur, for instance when the first snow of the winter fails to come, the nomads are allowed to pasture and water their livestock in especially for that purpose assigned sections of the National Park.
