Flora Of Vietnam
The wildlife of Vietnam is rich in flora and fauna as reflected by its unique biodiversity. Saola, rare and antelope-like animal categorized under the Bovinae, bovine subfamily, was found in 1992 in Vũ Quang National Park. In the 1990s, three other muntjac species, the deer-like Truong Son muntjac (found in Bạch Mã National Park), giant muntjac (found in Vũ Quang National Park) and Pu Hoat muntjac (found in Pù Hoạt, Nghệ An), were also discovered. Conservation protection and scientific studies of the ecology of Vietnam, particularly in the protected forest areas, have been given priority attention by the Government of Vietnam. Laws were enacted to set up Xuân Thủy Wetland National Park, four UNESCO Biosphere Reserves, and Hạ Long Bay and Phong Nha-Kẻ Bàng National Parks; the last two are also designated as UNESCO World Heritage Sites. The rich diversity of Vietnam's wildlife includes 11,400 species of vascular plants, 1030 species of moss, 310 species of mammals ...

Pseudoryx Nghetinhensis
The saola (''Pseudoryx nghetinhensis''), also called spindlehorn, Asian unicorn, or infrequently, Vu Quang bovid, is a forest-dwelling bovid native to the Annamite Range in Vietnam and Laos. It was described in 1993 following a discovery of remains in Vũ Quang National Park by a joint survey of the Vietnamese Ministry of Forestry and the World Wide Fund for Nature. Saolas have since been kept in captivity multiple times, although only for short periods as they died within a matter of weeks to months. The first photograph of a living saola was taken in captivity in 1993. The most recent one was taken in 2013 by a movement-triggered camera in the forest of central Vietnam, which represents the most recent record of the saola. There is concern that the species may already be extinct. It is the only species in the genus ''Pseudoryx'' and the earliest diverging member of the tribe Bovini, placing buffalo and cattle as its closest relatives. History of research and taxonomy In M ...

Vascular Plant
Vascular plants (), also called tracheophytes (, ) or collectively tracheophyta (; ), are plants that have lignin, lignified tissues (the xylem) for conducting water and minerals throughout the plant. They also have a specialized non-lignified Tissue (biology), tissue (the phloem) to conduct products of photosynthesis. The group includes most embryophyte, land plants ( accepted known species) excluding mosses. Vascular plants include the clubmosses, Equisetum, horsetails, ferns, gymnosperms (including conifers), and angiosperms (flowering plants). They are contrasted with nonvascular plants such as mosses and green algae. Scientific names for the vascular plants group include Tracheophyta, Tracheobionta and Equisetopsida sensu lato, Equisetopsida ''sensu lato''. Some early land plants (the rhyniophytes) had less developed vascular tissue; the term eutracheophyte has been used for all other vascular plants, including all living ones. Historically, vascular plants were known as "hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orchids
Orchids are plants that belong to the family Orchidaceae (), a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Orchids are cosmopolitan plants that are found in almost every habitat on Earth except glaciers. The world's richest diversity of orchid genera and species is in the tropics. Orchidaceae is one of the two largest families of flowering plants, the other being the Asteraceae. It contains about 28,000 currently accepted species in 702 genera. The Orchidaceae family encompasses about 6–11% of all species of seed plants. The largest genera are ''Bulbophyllum'' (2,000 species), ''Epidendrum'' (1,500 species), ''Dendrobium'' (1,400 species) and '' Pleurothallis'' (1,000 species). It also includes ''Vanilla'' (the genus of the vanilla plant), the type genus '' Orchis'', and many commonly cultivated plants such as '' Phalaenopsis'' and '' Cattleya''. Moreover, since the introduction of tropical species into cultivation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bamboo
Bamboos are a diverse group of mostly evergreen perennial plant, perennial flowering plants making up the subfamily (biology), subfamily Bambusoideae of the grass family Poaceae. Giant bamboos are the largest members of the grass family, in the case of ''Dendrocalamus sinicus'' having individual stalks (Culm (botany), culms) reaching a length of , up to in thickness and a weight of up to . The internodes of bamboos can also be of great length. ''Kinabaluchloa, Kinabaluchloa wrayi'' has internodes up to in length. and ''Arthrostylidium schomburgkii'' has internodes up to in length, exceeded in length only by Cyperus papyrus, papyrus. By contrast, the stalks of the tiny bamboo Raddiella, ''Raddiella vanessiae'' of the savannas of French Guiana measure only in length by about in width. The origin of the word "bamboo" is uncertain, but it most likely comes from the Dutch language, Dutch or Portuguese language, Portuguese language, which originally borrowed it from Malay langua ...

Oligocene
The Oligocene ( ) is a geologic epoch (geology), epoch of the Paleogene Geologic time scale, Period that extends from about 33.9 million to 23 million years before the present ( to ). As with other older geologic periods, the rock beds that define the epoch are well identified but the exact dates of the start and end of the epoch are slightly uncertain. The name Oligocene was coined in 1854 by the German paleontologist Heinrich Ernst Beyrich from his studies of marine beds in Belgium and Germany. The name comes from Ancient Greek (''olígos'') 'few' and (''kainós'') 'new', and refers to the sparsity of Neontology, extant forms of Mollusca, molluscs. The Oligocene is preceded by the Eocene Epoch and is followed by the Miocene Epoch. The Oligocene is the third and final epoch of the Paleogene Period. The Oligocene is often considered an important time of transition, a link between the archaic world of the tropical Eocene and the more modern ecosystems of the Miocene. Major chang ...

Red River Delta
The Red River Delta or Hong River Delta () is the flat low-lying plain formed by the Red River and its distributaries merging with the Thái Bình River in Northern Vietnam. ''Hồng'' (紅) is a Sino-Vietnamese word for "red" or "crimson". The delta has the smallest area but highest population and population density of all regions. The region, measuring some is well protected by a network of dikes. It is an agriculturally rich and densely populated area. Most of the land is devoted to rice cultivation. Eight provinces, together with two municipalities (the capital Hanoi, and the port of Haiphong) form the delta. It had a population of almost 23 million in 2019.

The definition sometimes also includes being financially beneficial to the host community or making conservation financially possible. There are a range of different definitions, and the correct definition of the term was an active subject of debate as of 2009. The term is also used more widely by many organizations offering nature tourism, which do not focus on being beneficial to the environment. Since the 1980s, ecotourism has been considered an important endeavor by environmentalists for conservation reasons. Organizations focusing on ecotourism often make direct or indirect contributions to conservation or employ practices or technology that reduce impacts on the environment. However (according to Bu ...

Landscape Xuan Thuy National Park
A landscape is the visible features of an area of land, its landforms, and how they integrate with natural or human-made features, often considered in terms of their aesthetic appeal.''New Oxford American Dictionary''. A landscape includes the physical elements of geophysically defined landforms such as mountains, hills, water bodies such as rivers, lakes, ponds and the sea, living elements of land cover including indigenous vegetation, human elements including different forms of land use, buildings, and structures, and transitory elements such as lighting and weather conditions. Combining both their physical origins and the cultural overlay of human presence, often created over millennia, landscapes reflect a living synthesis of people and place that is vital to local and national identity. The character of a landscape helps define the self-image of the people who inhabit it and a sense of place that differentiates one region from other regions. It is the dynamic backdrop to ...
