Introduction The Bactrian camel (Camelus bactrianus), an important member of the Camelidae family, plays a crucial role in the ecosystems and human civilizations of Central Asia and the inland regions of Asia. This ancient species has gone through a long evolutionary process and adapted to extremely arid and semi-arid environments. Its species and distribution not only reflect the shaping effect of the natural environment but also embody the profound influence of human activities. Species of the Bactrian Camel The Bactrian camel is divided into two main types: the wild Bactrian camel and the domesticated Bactrian camel, which have certain differences in genes, morphology, and behavioral habits. The wild Bactrian camel (Camelus ferus) is one of the rare wild animals in the world and is listed as a critically endangered species by the International Union for Conservation of Nature (IUCN). Its genes are significantly different from those of domesticated Bactrian camels, maintaining unique genetic purity. Wild Bactrian camels are relatively tall with long limbs. Their fur is mostly brown, and the texture is coarse and stiff, which helps them withstand sandstorms, heat, and cold in the harsh desert environment. Compared with domesticated Bactrian camels, the humps of wild Bactrian camels are more upright, and they have a stronger ability to store fat to adapt to long periods of food shortage. Domesticated Bactrian camels are the result of long-term human domestication. Through thousands of years of selective breeding, numerous local breeds have emerged. These breeds exhibit rich diversity in terms of body shape, fur color, milk production, and carrying capacity. For example, the Mongolian Bactrian camel has a robust build and strong endurance, making it suitable for long-distance transportation. Some Bactrian camel breeds in Xinjiang, China, are renowned for their excellent milk production performance. Domesticated Bactrian camels have a wide range of fur colors. Besides the common brown and tan, there are also white, gray, and other colors. Distribution of the Bactrian Camel Historical Distribution In ancient times, the distribution range of the Bactrian camel was relatively extensive, spanning a vast area in central and western Asia. From the west of China's Yellow River Basin, through the Mongolian Plateau, the desert and grassland regions of Central Asia, and extending all the way to parts of the Iranian Plateau and the Indian subcontinent, traces of Bactrian camels could be found. They were important means of transportation in the ancient Silk Road trade. As the caravans traveled, their distribution range continued to expand. Modern Distribution Distribution of Wild Bactrian Camels : At present, the distribution range of wild Bactrian camels has shrunk dramatically. They mainly inhabit the Lop Nur region in Xinjiang, China, Akesai County in Gansu Province, and the Gobi Desert in Mongolia. These areas are sparsely populated and retain a relatively primitive ecological environment. However, they also face threats such as water shortage, habitat fragmentation, and illegal hunting. Wild Bactrian camels choose to live in these areas because they have adapted to the extremely arid environment and can find sparse vegetation and limited water sources in the desert. Distribution of Domesticated Bactrian Camels : Domesticated Bactrian camels are widely distributed in many countries and regions in Central Asia and the inland of Asia. In China, Xinjiang, Inner Mongolia, Gansu, Qinghai and other provinces are the main breeding areas of Bactrian camels. These areas have vast grasslands and deserts, providing a suitable grazing environment for Bactrian camels. In Mongolia, the Bactrian camel is also one of the important livestock, mainly distributed in the southern Gobi region. In addition, Central Asian countries such as Kazakhstan and Kyrgyzstan also have a certain number of domesticated Bactrian camels being raised. Factors Affecting the Distribution of the Bactrian Camel Natural Environment The distribution of the Bactrian camel is closely related to the natural environment. They are adapted to arid and semi-arid climate conditions and can survive in environments with high temperatures, low temperatures, and strong sandstorms. The vegetation types and water source distribution in desert and grassland areas are important factors influencing the distribution of the Bactrian camel. They mainly feed on desert plants such as haloxylon ammodendron and calligonum mongolicum. The distribution range of these plants determines the foraging areas of the Bactrian camel. At the same time, the location and accessibility of water sources also limit the range of activities of the Bactrian camel. Since they need to drink water regularly, they are mostly distributed in areas close to water sources. Human Activities Human activities have had a profound impact on the distribution of the Bactrian camel. With the growth of the population and the development of the economy, the human exploitation and utilization of land have been increasing continuously, resulting in the destruction of the Bactrian camel's habitat. Large-scale agricultural reclamation, industrial construction, and the process of urbanization have encroached on the living space of the Bactrian camel, gradually shrinking its distribution range. In addition, overgrazing, illegal hunting and other behaviors have also posed a serious threat to the population size and distribution of the Bactrian camel. However, in some areas, humans have also carried out protection and management of the Bactrian camel through measures such as establishing nature reserves and conducting artificial breeding, which have, to a certain extent, maintained its population size and distribution. Conservation Status and Prospects Due to the scarce number of wild Bactrian camels, their conservation work has received widespread attention from the international community. Countries such as China and Mongolia have established multiple nature reserves. For example, the Lop Nur Wild Camel National Nature Reserve in Xinjiang, China, is dedicated to protecting the habitats of wild Bactrian camels. Meanwhile, law enforcement efforts have been strengthened to combat illegal hunting and trade. Some achievements have also been made in artificial breeding. The population of wild Bactrian camels has been increased through captive breeding. Regarding domesticated Bactrian camels, in some areas, the development of characteristic breeding and tourism has enhanced the economic value of Bactrian camels, thus promoting local herders to breed and protect them. In the future, it is necessary to further strengthen international cooperation to jointly protect the habitats of Bactrian camels, and enhance scientific research to gain a deeper understanding of their ecological habits and genetic diversity. This will provide a scientific basis for the conservation and rational utilization of this precious species. The species and distribution of the Bactrian camel are the result of the interaction between nature and human activities. Protecting the Bactrian camel is not only essential for safeguarding biodiversity but also an important measure to preserve human cultural heritage and maintain ecological balance.
