The Qionglai-Minshan conifer forests are a World Wide Fund for Nature ecoregion in Southwest China. These forests are classified as temperate coniferous forests and are part of the Palearctic realm.
The Qionglai-Minshan conifer forests cover the mountains along the easternmost edge of the Tibetan Plateau including the Min Mountains, Qionglai Mountains, Daxue Mountains, and Daliang Mountains. In addition to these mountain ranges, the lower reaches of the Dadu River valley support significant portions of the forests. The Qionglai-Minshan conifer forests are found almost entirely within western Sichuan, but small portions can also be found in southern Gansu and extreme northeast Yunnan. [1]
The understories of the Qionglai-Minshan conifer forests commonly feature bamboo, Larix griffithii, Larix potaninii, Pinus roxburghii, Pinus hwangshanensis, Pinus armandii, Juniperus tibetica, Juniperus communis, Shorea robusta, Olea europaea subsp. cuspidata, Tsuga dumosa, Taxus sumatrana, Betula utilis, Alnus nepalensis, Betula alnoides, Betula utilis, Picea brachytyla, Juglans regia, Larix gmelinii, Larix sibirica, Larix × czekanowskii, Betula dahurica, Betula pendula, Pinus koraiensis, Pinus sibirica, Pinus sylvestris, Picea obovata, Abies sibirica, Quercus acutissima, Quercus mongolica, Ginkgo biloba, Prunus serrulata, Prunus padus, Tilia amurensis, Salix babylonica, Acer palmatum, Populus tremula, Ulmus davidiana, Ulmus pumila, Pinus pumila, Haloxylon ammodendron, Elaeagnus angustifolia, Tamarix ramosissima , Prunus sibirica , Cathaya argyrophylla , Taiwania cryptomerioides , Cyathea spinulosa , Sassafras tzumu , Davidia involucrata , Metasequoia glyptostroboides , Glyptostrobus pensilis , Castanea mollissima , Quercus myrsinifolia , Quercus acuta , Machilus thunbergii , Tetracentron , Cercidiphyllum japonicum , Emmenopterys henryi , and Eucommia ulmoides . This ecoregion is one of the last remaining habitats where wild giant pandas can be found, alongside red pandas, clouded leopards, musk deer, Sichuan takin, and golden snub-nosed monkeys. [2] [3]
Conservation areas and scenic spots within the Qionglai-Minshan conifer forests include Wolong National Nature Reserve and Jiuzhaigou Valley.
The Northeast India-Myanmar pine forests is a montane subtropical coniferous forest ecoregion in the mountains of Northeastern India and adjacent portions of Myanmar.
The Caucasus mixed forests is a temperate broadleaf and mixed forests ecoregion in the Caucasus Mountains, as well as the adjacent Lesser Caucasus range and the eastern end of the Pontic Mountains.
The Eastern Himalayan broadleaf forests is a temperate broadleaf forest ecoregion found in the middle elevations of the eastern Himalayas, including parts of Nepal, India, Bhutan, Myanmar and China. These forests have an outstanding richness of wildlife.
The Western Himalayan broadleaf forests is a temperate broadleaf and mixed forest ecoregion which is found in the middle elevations of the western Himalayas, including parts of Nepal, India, and Pakistan.
The Eastern Himalayan subalpine conifer forests is a temperate coniferous forests ecoregion which is found in the middle and upper elevations of the eastern Middle Himalayas, in western Nepal, Bhutan, northern Indian states including Arunachal Pradesh and Sikkim and adjacent Myanmar and China.
The Northeastern Himalayan subalpine conifer forests are a temperate coniferous forests ecoregion of the middle to upper elevations of the eastern Himalayas and southeast Tibetan Plateau. The ecoregion occurs in southeastern Tibet Autonomous Region, China, in northern and eastern Arunachal Pradesh, India, and extreme eastern Bhutan.
The Western Himalayan subalpine conifer forests is a temperate coniferous forests ecoregion of the middle and upper elevations of the western Middle Himalayas of Nepal, India, and Pakistan.
The Sichuan Basin evergreen broadleaf forests are a critically endangered WWF ecoregion. The ecoregion occupies the Sichuan Basin in China and covers an area of 9,816,054 ha. The broadleaf forest habitat once covered the Sichuan Basin, but today is limited to mountains and preserved temple grounds in the basin and around the basin's rim. An especially well-preserved example of remaining forest exists on Mount Emei at the western edge of the Sichuan Basin. The original forests are thought to have been made up of subtropical oaks, laurels, and Schima. Much of the remaining Sichuan Basin has been converted to anthropogenic agricultural use in the last 5,000 years.
The Nujiang Lancang Gorge alpine conifer and mixed forests are a temperate coniferous forests ecoregion in Southwest China and northeastern Myanmar. The forests cover mountains and valleys in the western Hengduan Mountains and because of the extreme topography and relative remoteness, remain one of the best preserved habitats in China.
The Yunnan Plateau subtropical evergreen forests is an endangered ecoregion in southwestern China. These forests once covered the western parts of the Yungui Plateau but have been significantly reduced and replaced with agricultural land uses. The Yunnan evergreen forests and the neighbouring Guizhou Plateau broadleaf and mixed forests are the only two ecoregions in the Palearctic realm to be classified as part of tropical and subtropical moist broadleaf forests biome.
The Guizhou Plateau broadleaf and mixed forests are a subtropical moist broadleaf forest ecoregion in the Yungui Plateau of China. Much of the original forest has been replaced by secondary forests.
The Qilian Mountains Conifer Forests ecoregion is an ecoregion that consists of a series of isolated conifer forests on the northern slopes of the Qilian Mountain Range, on the northeast edge of the Tibetan Plateau in Qinghai and Gansu provinces of north-central China.
The Tian Shan montane conifer forests ecoregion covers the "forest belt" of the Tian Shan mountains - generally the north-facing slopes that get enough moisture, and are warm enough, for trees to grow. This conifer belt is found mostly between 1,500 and 2,700 meters.
The Tian Shan foothill arid steppe ecoregion covers the northern and western approaches to the Tian Shan mountains, centered on Lake Issyk-Kul in Kyrgyzstan. This region receives more moisture from Central Asia, thereby supporting more vegetation and diversity of plant and animal species than the deserts to the south.
The Gissaro-Alai open woodlands ecoregion covers the western foothills winding around two western offshoots of the Tian Shan Mountains in western Tajikistan, and parts of eastern Uzbekistan and western Kyrgyzstan, in Central Asia. The woodlands are typically of Juniper trees and shrubs, fitting the altitude zone situated between the desert valley floor, and the tree line, above which the mountain ridges are glaciated and barren.
The Northern Triangle subtropical forests ecoregion covers remote, mountainous terrain in the far north of Myanmar. Due to the regions isolation it is relatively untouched and unexplored by humans. Over 95% of the ecoregion is covered with closed evergreen forest, and importantly for conservation, these forests exist in large contiguous blocks. As of the late 1990s, 140 mammal species were known to be in the region, and new species, such the Leaf muntjac discovered in 1997, are still being found.
The East Afghan montane conifer forests ecoregion covers a series of unconnected conifer forests along the border between Afghanistan and Pakistan, at elevations of 2,000 metres (6,600 ft) to 3,400 metres (11,200 ft) above sea level. The ecoregion supports the near-threatened Markhor (Capra falconeri chiltanensis), known as the Screw-horned goat, the national animal of Pakistan. The forests of the ecoregion have been heavily thinned for timber.
The Central Afghan Mountains xeric woodlands ecoregion covers the xeric (dry) eastern and southern slopes of the central mountain range of Afghanistan, between the sandy desert to the south and the alpine meadows in the higher, wetter region to the north. Despite the 'woodlands' in the ecoregion name, very little of the territory is forested – less than 1% – but is instead sparse vegetation or herbaceous cover.
The Paropamisus xeric woodlands ecoregion covers the portion of northeastern Afghanistan north of the central mountain range and the Hindu Kush Mountains. The name is derived from the Old Persian name for the region, Parupraesanna. While there are low canopy woodlands in the northeast of the ecorgegion, most of the territory is desert or xeric (dry) scrubland.
The Baluchistan xeric woodlands ecoregion covers the middle elevations of a series of mountain ranges of western Pakistan and northeastern Afghanistan, reaching 1,200 kilometres (750 mi) from the Arabian Sea in the south to the Hindu Kush Mountains and the Himalayas in the north. The characteristic vegetation is xeric (dry) woodlands of shrubs and herbaceous cover. The region has rich biodiversity but relatively few endemic species.
