Central Indochina Dry Forests
The Central Indochina dry forests are a large tropical and subtropical dry broadleaf forests ecoregion in Southeast Asia. Location and description The ecoregion consists of an area of plateau and low river basin in Cambodia, Thailand, Laos, and Vietnam and includes: *In Thailand the large Khorat Plateau, the higher elevation plains of the Chao Phraya River basin, the foothills of the Tenasserim Hills and other dry areas of the lower slopes of the Khun Tan, Phi Pan Nam and Phetchabun mountain ranges of the north of the country. *In central and southern Laos the wide valley of the Mekong river system. *In Cambodia a large area of the dry plains of the northern, eastern, and south-central parts of the country. *In Vietnam the uplands of the upper Tonlé San and Srepok Rivers. These are the drier areas of Indochina with 1,000-1,500 mm rainfall per year and a long dry season when regular fires occur in the undergrowth, some set intentionally to clear the forest or drive ou ...

Phi Pan Nam Range
The Phi Pan Nam Range, also Pee Pan Nam, ( th, ทิวเขาผีปันน้ำ) is a long system of mountain ranges in the eastern half of the Thai highlands. It is mostly in Thailand, although a small section in the northeast is within Sainyabuli and Bokeo Provinces, Laos. In Thailand the range extends mainly across Chiang Rai, Phayao, Lampang, Phrae, Nan, Uttaradit and Sukhothai Provinces, reaching Tak Province at its southwestern end. The population density of the area is relatively low. Only two sizable towns, Phayao and Phrae, are within the area of the mountain system and both have fewer than 20,000 inhabitants each. Larger towns, like Chiang Rai and Uttaradit, are near the limits of the Phi Pan Nam Range, in the north and in the south respectively. Phahonyothin Road, part of the AH2 Highway system, crosses the Phi Pan Nam Range area from north to south, between Tak and Chiang Rai. There are two railway tunnels of the Northern Line across the Phi Pan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tonle Sap Freshwater Swamp Forests
The Tonle Sap freshwater swamp forests ecoregion (WWF ID: IM0164) covers the seasonally flooded forests surrounding Tonlé Sap, the largest lake in Cambodia, and the floodplains of its connections to the Mekong River . Over 35% of the ecoregion experiences flooding during the wet season (August – January). Location and description The ecoregion stretches about 400 km from the northern wetlands of Tonle Sap Lake to the salt-water affected mangroves of the Mekong River Delta. The region follows the boundaries of the floodplain of the lake and the Tonle Sap River. The region is flat, although a few hills rise to 300 meters. Climate The climate of the ecoregion is '' Tropical savanna climate - dry winter'' (Köppen climate classification (Aw)). This climate is characterized by relatively even temperatures throughout the year, and a pronounced dry season. The driest month has less than 60 mm of precipitation, and is drier than the average month. Flora and fauna Half of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deciduous
In the fields of horticulture and Botany, the term ''deciduous'' () means "falling off at maturity" and "tending to fall off", in reference to trees and shrubs that seasonally shed leaves, usually in the autumn; to the shedding of petals, after flowering; and to the shedding of ripe fruit. The antonym of ''deciduous'' in the botanical sense is evergreen. Generally, the term "deciduous" means "the dropping of a part that is no longer needed or useful" and the "falling away after its purpose is finished". In plants, it is the result of natural processes. "Deciduous" has a similar meaning when referring to animal parts, such as deciduous antlers in deer, deciduous teeth (baby teeth) in some mammals (including humans); or decidua, the uterine lining that sheds off after birth. Botany In botany and horticulture, deciduous plants, including trees, shrubs and herbaceous perennials, are those that lose all of their leaves for part of the year. This process is called ...

Indochina
Mainland Southeast Asia, also known as the Indochinese Peninsula or Indochina, is the continental portion of Southeast Asia. It lies east of the Indian subcontinent and south of Mainland China and is bordered by the Indian Ocean to the west and the Pacific Ocean to the east. It includes the countries of Cambodia, Laos, Myanmar, Thailand and Vietnam, with peninsular Malaysia sometimes also being included. The term Indochina (originally Indo-China) was coined in the early nineteenth century, emphasizing the historical cultural influence of Indian and Chinese civilizations on the area. The term was later adopted as the name of the colony of French Indochina (today's Cambodia, Laos, and Vietnam). Today, the term, Mainland Southeast Asia, in contrast to Maritime Southeast Asia, is more commonly referenced. Terminology The origins of the name Indo-China are usually attributed jointly to the Danish-French geographer Conrad Malte-Brun, who referred to the area as in 1804, and ...

Srepok River
The Srepok River ( km, ទន្លេស្រែពក, ; vi, Sông Sêrêpôk) is a major tributary of the Mekong River. It runs from Đắk Lắk Province in the Central Highlands of Vietnam through the Ratanakiri and Stung Treng provinces in Cambodia to join the Mekong near Stung Treng town. Its length varies from 406 km to 450 km in which the last 281 km course is in Cambodian territory. The Srepok River, in turn, has three main tributaries: the Krông Nô, Krông Ana, and Ea H'leo Rivers. Before joining the Mekong, the Srepok also merges with the Sesan River and Kong River in Stung Treng province. In Vietnam, it is also called Dak Krong river. Course Forming from two tributaries—Krông Nô and Krông Ana rivers in the western side of the South Annamite Mountain Range in Vietnam's Central Highlands province of Đắk Lắk—the Srepok runs through Krông Ana, Buôn Đôn, and Ea Súp districts to the west.

Mekong
The Mekong or Mekong River is a trans-boundary river in East Asia and Southeast Asia. It is the world's twelfth longest river and the third longest in Asia. Its estimated length is , and it drains an area of , discharging of water annually. From the Tibetan Plateau the river runs through China, Myanmar, Laos, Thailand, Cambodia, and Vietnam. The extreme seasonal variations in flow and the presence of rapids and waterfalls in the Mekong make navigation difficult. Even so, the river is a major trade route between western China and Southeast Asia. Names The Mekong was originally called ''Mae Nam Khong'' from a contracted form of Tai shortened to ''Mae Khong''. In Thai and Lao, ''Mae Nam'' ("Mother of Water ) is used for large rivers and ''Khong'' is the proper name referred to as "River Khong". However, ''Khong'' is an archaic word meaning "river", loaned from Austroasiatic languages, such as Vietnamese ''sông'' (from *''krong'') and Mon ''kruŋ'' "river", which led to ...

Phetchabun Mountains
The Phetchabun mountains ( th, ทิวเขาเพชรบูรณ์, , ) are a mountain massif in Phetchabun, Phitsanulok, Loei and Chaiyaphum Provinces, Thailand. It consists of two parallel mountain chains, with the valley of the Pa Sak River in the middle. The strange rock formations of Phu Hin Rong Kla and fields where the Siam tulip flower (''Curcuma alismatifolia''), known as ''dok krachiao'' (ดอกกระเจียว) in Thai, grows wild are some of the characteristics of the Phetchabun Mountains. Geography The mountain system as a whole is named after the city of Phetchabun which lies within the mountainous area. To the south and southeast lie the Dong Phaya Yen Mountains. Both sections of the Phetchabun massif are parallel and of a similar length, extending in a roughly north-south direction. The western range is a prolongation of the southern end of the Luang Prabang Range. The eastern range separates the broad Chao Phraya river basin of central Tha ...

Khun Tan Range
The Khun Tan Range ( th, ทิวเขาขุนตาน or, erroneously, ทิวเขาขุนตาล) is a mountain range that occupies a central position in Northern Thailand. Most of the range is located in Chiang Mai, western Chiang Rai, Lampang and Lamphun Provinces. The geological composition of the Khun Tan mountains is different from the neighboring Thanon Thong Chai Range in the west and the Daen Lao Range in the north. Precambrian rocks are absent in this mountain chain which is thus not part of the Shan Hills system. The geology of the Khun Tan Range is homogeneous with the Phi Pan Nam Range further east and some scholarly works designate the Khun Tan as the "Western Phi Pan Nam Range", including it as part of the Phi Pan Nam Mountain System. Geography The Khun Tan Range begins south of the Kok River valley, at the southern end of the Daen Lao Range in Fang District. It stretches southwards in a north/south direction turning midway to a ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tenasserim Hills
The Tenasserim Hills or Tenasserim Range ( my, တနင်္သာရီ တောင်တန်း, ; th, ทิวเขาตะนาวศรี, , ; ms, Banjaran Tanah Seri/Banjaran Tenang Sari) is the geographical name of a roughly 1,700 km long mountain chain, part of the Indo-Malayan mountain system in Southeast Asia. Despite their relatively scant altitude these mountains form an effective barrier between Thailand and Myanmar in their northern and central region. There are only two main transnational roads and cross-border points between Kanchanaburi and Tak, at the Three Pagodas Pass and at Mae Sot. The latter is located beyond the northern end of the range, where the Tenasserim Hills meet the Dawna Range. Minor cross-border points are Sing Khon, near Prachuap Khiri Khan, as well as Bong Ti and Phu Nam Ron west of Kanchanaburi. The latter is expected to gain in importance if the planned Dawei Port Project goes ahead, along with a highway an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chao Phraya River
The Chao Phraya ( or ; th, แม่น้ำเจ้าพระยา, , or ) is the major river in Thailand, with its low alluvial plain forming the centre of the country. It flows through Bangkok and then into the Gulf of Thailand. Etymology On many old European maps, the river is named the ''Mae Nam'' (Thai: แม่น้ำ), the Thai word for "river" (literally, "motherly water"). James McCarthy, F.R.G.S., who served as Director-General of the Siamese Government Surveys prior to establishment of the Royal Survey Department, wrote in his account, "''Mae Nam'' is a generic term, ''mae'' signifying "mother" and ''Nam'' "water," and the epithet Chao P'ia signifies that it is the chief river in the kingdom of Siam." H. Warington Smyth, who served as Director of the Department of Mines in Siam from 1891 to 1896, refers to it in his book first published in 1898 as "the Mae Nam Chao Phraya". In the English-language media in Thailand, the name Chao Phraya River is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Khorat Plateau
The Khorat Plateau ( th, ที่ราบสูงโคราช) is a plateau in the northeastern Thai region of Isan. The plateau forms a natural region, named after the short form of Nakhon Ratchasima, a historical barrier controlling access to and from the area. Geography The average elevation is and it covers an area of about . The saucer-shaped plateau is divided by a range of hills called the Phu Phan Mountains into two basins: the northern Sakhon Nakhon Basin, and the southern Khorat Basin. The plateau tilts from its northwestern corner where it is about above sea level to the southeast where the elevation is only about . Except for a few hills in the northeastern corner, the region is primarily gently undulating land, most of it varying in elevation from , tilting from the Phetchabun Mountains in the west down toward the Mekong River. The plateau is drained by the Mun and Chi Rivers, tributaries to the Mekong that forms the northeastern boundary of the area. It is s ...
