Conifer
Conifers () are a group of conifer cone, cone-bearing Spermatophyte, seed plants, a subset of gymnosperms. Scientifically, they make up the phylum, division Pinophyta (), also known as Coniferophyta () or Coniferae. The division contains a single extant class (biology), class, Pinopsida. All Neontology, extant conifers are perennial plant, perennial woody plants with secondary growth. The majority are trees, though a few are shrubs. Examples include Cedrus, cedars, Pseudotsuga, Douglas-firs, Cupressaceae, cypresses, firs, junipers, Agathis, kauri, larches, pines, Tsuga, hemlocks, Sequoioideae, redwoods, spruces, and Taxaceae, yews.Campbell, Reece, "Phylum Coniferophyta". ''Biology''. 7th ed. 2005. Print. p. 595. As of 2002, Pinophyta contained seven families, 60 to 65 genera, and more than 600 living species.

Truong Son Muntjac
The Truong Son muntjac or Annamite muntjac (''Muntiacus truongsonensis'') is a species of muntjac deer. It is one of the smallest muntjac species, at about , half the size of the Indian muntjac (or common muntjac). It was discovered in the Truong Son (Annamite) mountain range in Vietnam Vietnam, officially the Socialist Republic of Vietnam (SRV), is a country at the eastern edge of mainland Southeast Asia, with an area of about and a population of over 100 million, making it the world's List of countries and depende ... in 1997. It was identified by examination of skulls and descriptions provided by villagers, who call it ''samsoi cacoong'', or "the deer that lives in the deep, thick forest." It lives at elevations of 400–1000 metres, where its small size allows it to move through dense undergrowth.

Roosevelt's Muntjac
A single specimen of the Roosevelt's muntjac or Roosevelt's barking deer (''Muntiacus rooseveltorum'') was presented to the Field Museum in 1929 following the Kelley-Roosevelts expedition organized by Theodore (Jnr) and Kermit Roosevelt. The specimen is slightly smaller than the common muntjac and DNA testing has shown it to be distinct from recently discovered muntjac species. It is a subspecies of Fea's muntjac, whose home range is mountains further northwest separated by lower land. However, without further evidence, the exact position of Roosevelt's muntjac cannot be stated. Berlin Zoo supposedly held this species between 1961 and 1972 (following an import from Northern Vietnam) but it could have been an Indian muntjac, subspecies ''annamensis''. Roosevelt's muntjac was believed to have been extinct since 1929. However, there have been several recent claims to have rediscovered the species, from evidence including skulls owned by villagers in the Truong Son (Annamite) mo ...

Giant Muntjac
The giant muntjac (''Muntiacus vuquangensis''), sometimes referred to as the large-antlered muntjac, is a species of muntjac deer. It is the largest muntjac species and was discovered in 1994 in Vũ Quang, Hà Tĩnh Province of Vietnam and in central Laos. During inundation of the Nakai Reservoir in Khammouane Province of Laos for the Nam Theun 2 Multi-Purpose Project, 38 giant muntjac were captured, studied, and released into the adjacent Nakai-Nam Theun National Protected Area. Subsequent radio-tracking of a sample of these animals showed the relocation was successful. The species is also located in parts of eastern Cambodia, as well as the Annamite Mountains (Trường Sơn Mountains). The giant muntjac is commonly found in evergreen forests and weighs about . It has a red-brown coat and is an even-toed ungulate. Due to slash-and-burn agriculture, combined with hunting, the giant muntjac is considered critically endangered. It is preyed upon by animals such as the tiger a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saola
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 ...

Threatened Species
A threatened species is any species (including animals, plants and fungi) which is vulnerable to extinction in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of ''critical depensation'', a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment without direct reference to human activity. IUCN definition The International Union for Conservation of Nature (IUCN) is the foremost authority on threatened species, and treats threatened species not as a single category, but as a group of three categories, depending on the degree to which they are threatened: *Vulnerable species *Endangered species *Critically endangered species Less-than-threatened categories are near threatened, least concern, and the no longer assigned category of conservation dependent. Species that have not been evaluated (NE), or do not have sufficient data ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cloud Forest
A cloud forest, also called a water forest, primas forest, or tropical montane cloud forest, is a generally tropical or subtropical, evergreen, Montane forest, montane, Tropical and subtropical moist broadleaf forests, moist forest characterized by a persistent, frequent or seasonal low-level cloud cover, usually at the canopy level, formally described in the ''International Cloud Atlas'' (2017) as silvagenitus. Cloud forests often exhibit an abundance of mosses covering the ground and vegetation, in which case they are also referred to as mossy forests. Mossy forests usually develop on the mountain pass, saddles of mountains, where moisture introduced by settling clouds is more effectively retained. Cloud forests are among the most biodiversity-rich ecosystems in the world, with a large number of species directly or indirectly depending on them. Other moss forests include black spruce/feathermoss Climax community, climax forest, with a moderately dense canopy and a forest fl ...
