The county was first established on December 27, 1952, being part of neighboring counties before then. The county

36-640: A Celtis host plant. Some species of Celtis are threatened by habitat destruction . Several species are grown as ornamental trees, valued for their drought tolerance. They are a regular feature of arboreta and botanical gardens, particularly in North America. Chinese hackberry ( C. sinensis ) is suited for bonsai culture; a magnificent specimen in Daegu-myeon is one of the natural monuments of South Korea. The berries are generally edible when they ripen and fall. C. occidentalis fruit

54-543: A date . Previously included either in the elm family ( Ulmaceae ) or a separate family, Celtidaceae, the APG III system places Celtis in an expanded hemp family (Cannabaceae). Members of the genus are present in the fossil record as early as the Miocene of Europe, and Paleocene of North America and eastern Asia. The derivation of the name of this genus, Celtis , is from a Latin word for an unrelated plant,

72-748: A central storage facility in the Qinling mountain range, though some are kept at smaller regional storage facilities." Celtis Some 60–70 (see below) Celtis is a genus of about 60–70 species of deciduous trees, commonly known as hackberries or nettle trees , in the hemp family Cannabaceae . It has a cosmopolitan distribution . Celtis species are generally medium-sized trees, reaching 10–25 metres (33–82 feet) tall, rarely up to 40 m (130 ft) tall. The leaves are alternate, simple, 3–15 centimetres ( 1 + 1 ⁄ 4 –6 inches) long, ovate - acuminate , and evenly serrated margins. Diagnostically, Celtis can be very similar to trees in

90-528: A peak in the 18th century in the Qinling Mountains. The region is home to the endemic Qinling panda ( Ailuropoda melanoleuca qinlingensis ), a brown-and-white subspecies of the giant panda ( A. melanoleuca ), which is protected with the help of the Changqing and Foping nature reserves . An estimated 250 to 280 pandas live in the region, which is thought to represent around one-fifth of

108-460: A pollen source for honeybees of lesser importance. Celtis species are used as food plants by the caterpillars of certain Lepidoptera . These include mainly brush-footed butterflies , most importantly the distinct genus Libythea (beak butterflies) and some Apaturinae (emperor butterflies): The plant pathogenic basidiomycete fungus Perenniporia celtis was first described from

126-569: Is about 100 kilometers (62 mi) west of the ancient Chinese capital of Xi'an . Three culturally significant peaks in the range are Mount Hua (2,155 meters or 7,070 feet), Mount Li (1,302 meters or 4,272 feet), and Mount Maiji (1,742 meters or 5,715 feet). The environment of the Qin Mountains is a deciduous forest ecoregion . The Qin Mountains form the watershed of the Yellow River and Yangtze River basins; historically,

144-448: Is consequently somewhat impoverished in regard to fertility and species diversity. Furthermore, the mountains have also acted in the past as a natural defense against nomadic invasions from the north, as only four passes cross the mountains. In the late 1990s a railway tunnel and a spiral were completed, thereby easing travel across the range. The highest mountain in the range is Mount Taibai at 3,767 meters (12,359 ft), which

162-612: Is noted for its high air quality, 92% of the county is covered by forests. As 2020, Taibai County is divided to 7 towns. In 2001, Baiyun township was merged into Zuitou and Erlangba township was merged into Huangbaiyuan. In 2011, Guanglong township was merged into Yingge, and Huangbaiyuan and Wangjialeng were changed from township to town. This Shaanxi location article is a stub .

180-541: Is one of the largest amphibians in the world, and is critically endangered ; it is locally pursued for food, and for use of its body parts in traditional Chinese medicine . An environmental education program is being undertaken to encourage sustainable management of wild populations in the Qin Mountains, and captive-breeding programs have also been set up. According to the Nuclear Information Project, China "keeps most of its nuclear warheads at

198-593: The Nanshan ("Southern Mountains"), are a major east–west mountain range in southern Shaanxi Province, China. The mountains mark the divide between the drainage basins of the Yangtze and Yellow River systems, providing a natural boundary between North and South China and support a huge variety of plant and wildlife, some of which is found nowhere else on earth. To the north is the densely populated Wei River valley, an ancient center of Chinese civilization. To

216-476: The Rosaceae and other rose motif families. Small flowers of this monoecious plant appear in early spring while the leaves are still developing. Male flowers are longer and hairy. Female flowers are greenish and more rounded. The fruit is a small drupe 6–10 millimetres ( 1 ⁄ 4 – 3 ⁄ 8  in) in diameter, edible in many species, with a dryish but sweet, sugary consistency, reminiscent of

234-428: The understory . The region is home to a large number of rare plants, of which around 3,000 have been documented. Plant and tree species native to the region include ginkgo ( Ginkgo biloba —thought to be one of the oldest species of tree in the world), as well as Huashan or Armand pine ( Pinus armandii ), Huashan shen ( Physochlaina infundibularis ), Acer miaotaiense and Chinese fir .

252-512: The "lotus tree" of North Africa. The word was applied to this taxon by Linnaeus for unknown reasons. As of July 2024 , the following 68 species are accepted by Plants of the World Online . The genus is widespread throughout tropical and temperate parts of the world, occurring on all continents except Antarctica. Some species, including common hackberry ( C. occidentalis ) and C. brasiliensis , are honey plants and

270-569: The entire wild giant panda population. The Qinling Mountains are also home to many other species of wildlife, including numerous birds , like the crested ibis , Temminck's tragopan , golden eagle , black throat and golden pheasants , as well as mammals like the Asiatic golden cat , Asiatic black bear , clouded leopard , golden takin , golden snub-nosed monkey , yellow-throated marten , and leopard .

288-813: The former was home to deciduous broadleaf forests, while the latter has milder winters with more rainfall, and was generally covered in warmer, temperate, evergreen broadleaf forests. Thus, the Qin Mountains are commonly used as the demarcation line between northern and southern China . The low-elevation forests of the Qin foothills are dominated by temperate deciduous trees, like oaks ( Quercus acutissima , Q. variabilis ), elm ( Ulmus spp.), common walnut ( Juglans regia ), maple ( Acer spp.), ash ( Fraxinus spp.) and Celtis spp. Evergreen species of these low-elevation forests include broadleaf chinquapins ( Castanopsis sclerophylla ), ring-cupped oaks ( Quercus glauca ), and conifers , like Pinus massoniana . At

324-527: The south is the Han River valley. To the west is the line of mountains along the northern edge of the Tibetan Plateau . To the east are the lower Funiu and Dabie Mountains, which rise out of the coastal plain. The northern side of the range is prone to hot weather, the rain shadow cast by the physical barrier of the mountains dictating that the land to the north has a semi-arid climate, and
