Asana River
Asana River (Río Asana) is a waterway in the Moquegua Region of southern Peru. It is one of the tributaries of the Osmore River (also known as Moquegua or Tumilaca). The Asana, Peru, Asana archaeological site, occupied over the course of 8,000 years, is situated in a basin on the river's north bank. The Quellaveco mining project sought to divert the Asana for extractive waste material placement in its copper mining operations. Geography The Asana River is one of the four major tributaries of the Moquegua. It is situated in the south central Andes mountains. The main Asana has its primary source at an elevation of . This is within the pampas in the peripheral region of the high Puna grassland, puna, defined as an area (''Pampa Tinajones'' and Apachita Limani) above elevation. The river's Surface runoff, runoff source is seasonal precipitation including snow melt from the western cordillera of the Andes. One of the Asana's tributaries is the Charaque. After their confluence, the st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterway
A waterway is any navigable body of water. Broad distinctions are useful to avoid ambiguity, and disambiguation will be of varying importance depending on the nuance of the equivalent word in other languages. A first distinction is necessary between maritime shipping routes and waterways used by inland water craft. Maritime shipping routes cross oceans and seas, and some lakes, where navigability is assumed, and no engineering is required, except to provide the draft for deep-sea shipping to approach seaports (channels), or to provide a short cut across an isthmus; this is the function of ship canals. Dredged channels in the sea are not usually described as waterways. There is an exception to this initial distinction, essentially for legal purposes, see under international waters. Where seaports are located inland, they are approached through a waterway that could be termed "inland" but in practice is generally referred to as a "maritime waterway" (examples Seine Maritime, Loir ...

Chenopodium Petiolare
''Chenopodium'' is a genus of numerous species of perennial or annual herbaceous flowering plants known as the goosefoots, which occur almost anywhere in the world. It is placed in the family Amaranthaceae in the APG II system; older classification systems, notably the widely used Cronquist system, separate it and its relatives as Chenopodiaceae, but this leaves the rest of the Amaranthaceae polyphyletic. However, among the Amaranthaceae, the genus ''Chenopodium'' is the namesake member of the subfamily Chenopodioideae. Description The species of ''Chenopodium'' (s.str., description according to Fuentes et al. 2012) are annual or perennial herbs, shrubs or small trees. They generally rely on alkaline soil. They are nonaromatic, but sometimes fetid. The young stems and leaves are often densely covered by vesicular globose hairs, thus looking farinose. Characteristically, these trichomes persist, collapsing later and becoming cup-shaped. The branched stems grow erect, ascendin ...

Bofedales
Bofedales (singular ''bofedal''), known in some parts of Peru as ''oconales'', are a type of wetland found in the Andes in Peru and Chile. They are a feature in the land use and ecology of high Andean ecosystems. They form in flat areas around ponds or streams and may be permanent or seasonal, and they can be man made or natural. The soil in a bofedal will be moist throughout the year. Bofedales are associated with peat in the soil and the presence of humidity in the soil means that they are green throughout the year. Bofedales are found above above sea level (asl), although some classifications put them no lower than asl. The Ramsar Convention describes bofedales as peatlands without forest. Bofedales absorb the limited amount of water derived from snow, glacier meltwater and rain showers storing it in ground and slowly releasing it. The water can be either fresh or saline. Their vegetation is slow-growing and tough, made up of grasses, especially rushes, and some low spreading ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pampa
The Pampas (from the qu, pampa, meaning "plain") are fertile South American low grasslands that cover more than and include the Argentine provinces of Buenos Aires, La Pampa, Santa Fe, Entre Ríos, and Córdoba; all of Uruguay; and Brazil's southernmost state, Rio Grande do Sul. The vast plains are a natural region, interrupted only by the low Ventana and Tandil hills, near Bahía Blanca and Tandil (Argentina), with a height of and , respectively. The climate is temperate, with precipitation of that is more or less evenly distributed throughout the year, making the soils appropriate for agriculture. The area is also one of the distinct physiography provinces of the larger Paraná–Paraguay plain division. Topography This region has generally low elevations, whose highest levels do not exceed 600 metres (1,970 feet) in altitude. The coastal areas and most of the Buenos Aires Province are predominantly plain (with some wetlands) and the interior areas (mainly in the sou ...

Polylepis
''Polylepis'' is a genus comprising 28 recognised shrub and tree species, that are endemic to the mid- and high-elevation regions of the tropical Andes. This group is unique in the rose family in that it is predominantly wind-pollinated. They are usually gnarled in shape, but in certain areas some trees are 15–20 m tall and have 2 m-thick trunks. The foliage is evergreen, with dense small leaves, and often having large amounts of dead twigs hanging down from the underside of the canopy. The name ''Polylepis'' is, in fact, derived from the Greek words poly (many) plus letis (layers), referring to the shredding, multi-layered bark that is common to all species of the genus. The bark is thick and rough and densely layered for protection against low temperatures. Some species of ''Polylepis'' form woodlands growing well above normal tree line within grass and scrub associations at elevations over 5000 m; which makes ''Polylepis'' appear to be the highest naturally occurring arbor ...

Jarava Ichu
''Jarava ichu'', commonly known as Peruvian feathergrass, ''ichhu'', ''paja brava'', ''paja ichu'', or simply ''ichu'' (Quechua for straw), is a grass species in the family Poaceae native to the Americas. It is found growing in a vast area: Mexico, Guatemala, Costa Rica, El Salvador, Venezuela, Bolivia, Colombia, Ecuador, Peru, Chile, and Argentina. It is a common grass of the Andean altiplano. It is used as fodder for livestock. Under the synonym ''Stipa ichu'', it has won the Royal Horticultural Society The Royal Horticultural Society (RHS), founded in 1804 as the Horticultural Society of London, is the UK's leading gardening charity. The RHS promotes horticulture through its five gardens at Wisley (Surrey), Hyde Hall (Essex), Harlow Carr (Nor ...'s Award of Garden Merit.

Parastrephia Lepidophylla
''Parastrephia lepidophylla'', commonly known as tola or tola tola, is a species of flowering plant in the family Asteraceae. It is native to South America and has been recorded from Argentina, Bolivia, Chile and Peru where it is characteristic of the puna grassland ecoregion. It is a resinous shrub, growing up to 2 m in height, that is typically found in semi-arid central Andean dry, or tola heath, puna habitats, at altitudes of 3500–5000 m above sea level, and in the undergrowth of central Andean ''Polylepis ''Polylepis'' is a genus comprising 28 recognised shrub and tree species, that are endemic to the mid- and high-elevation regions of the tropical Andes.
