Somawathiya National Park
Somawathiya National Park is one of the four national parks designated under the Mahaweli River development project. Senarathna 2004: p. 166 Somawathiya Chaitya, a stupa said to be containing a relic of the tooth of the Buddha, is situated within the park. The park was created on 2 September 1986, having been originally designated a wildlife sanctuary on 9 August 1966. The park is home to many megaherbivores. The national park is located north-east of Colombo. Physical features Somawathiya National Park lies in the deltaic flood plains of the Mahaweli River and contains the junction where it is forked into two branches. The two branches are the Mahaweli River, which flows north into Koddiyar bay and the lesser Verugal Oya which flows north-east into the sea. The central riparian flood plain is featured by many old river channels and contain dispersed 'villus', the waterfilled basins around among the grassy plains. There are 20 such villus is located in the park. Somawathiya an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Central Province, Sri Lanka
North Central Province ( si, උතුරු මැද පළාත ''Uturumæda Paḷāta'', ta, வட மத்திய மாகாணம் ''Wada Maththiya Mākāṇam'') is one of the nine provinces of Sri Lanka, the first level administrative division of the country. The provinces have existed since the 19th century but did not have any legal status until 1987 when the 13th Amendment to the Constitution of Sri Lanka established provincial councils. The province is the largest by size, and second least populated in the country. The province consists of the districts of Anuradhapura and Polonnaruwa, both of which were important ancient Sri Lankan kingdoms. The climate is semi-arid, and the forests are dry evergreen forests. History The centralised system of Sri Lanka, which is a unitary state, failed to satisfy the aspirations of the people. There was growing insistence on decentralisation of administrative processes to achieve rapid economic and social development of t ...

Ludwigia Hexapetala
''Ludwigia hexapetala'', the water primrose, is a herbaceous perennial plant of the family Onagraceae. Native to Central and South America, its habitat includes the margins of lakes, ponds, ditches, and streams. Its stems may be immersed or fully emergent. It is a noxious invader of aquatic ecosystems in North America. Habitat ''Ludwigia hexapetala'' is native to Latin America. It occurs naturally in swampier regions, such as those of lakes, ponds, and other areas of low intensity/stagnant water. It grows in mats of up to three feet tall, and in doing so, it crowds and/or shades out the other, more native species. The plant is known to inhabit the Southeast United States, Midwest United States, Pacific Coast, and parts of New England New England is a region comprising six states in the Northeastern United States: Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont. It is bordered by the state of New York (state), New York to the west and by the Ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polygonum
''Polygonum'' is a genus of about 130 species of flowering plant in the buckwheat and knotweed family Polygonaceae. Common names include knotweed and knotgrass (though the common names may refer more broadly to plants from Polygonaceae). In the Middle English glossary of herbs ''Alphita'' ( 1400–1425), it was known as ars-smerte. There have been various opinions about how broadly the genus should be defined. For example, buckwheat (''Fagopyrum esculentum'') has sometimes been included in the genus as ''Polygonum fagopyrum''. Former genera such as ''Polygonella'' have been subsumed into ''Polygonum''; other genera have been split off. The genus primarily grows in northern temperate regions. The species are very diverse, ranging from prostrate herbaceous annual plants to erect herbaceous perennial plants. ''Polygonum'' species are occasionally eaten by humans, and are used as food plants by the larvae of some Lepidoptera species – see list. Most species are considered we ...

Alternanthera Sessilis
''Alternanthera sessilis'' is a flowering plant known by several common names, including sissoo spinach, Brazilian spinach, sessile joyweed and dwarf copperleaf. It is cultivated as a vegetable worldwide. Distribution The plant occurs throughout the tropical and subtropical regions of the Old World. It has been introduced to the southern United States, and its origins in Central and South America are uncertain. This species is classified as a weed in parts of the southern states of the USA. It is usually (but not always especially in areas of high humidity where it can even be a garden weed) found in wet or damp spots. Description This is a perennial herb with prostrate stems, rarely ascending, often rooting at the nodes. Leaves obovate to broadly elliptic, occasionally linear-lanceolate, 1–15 cm long, 0.3–3 cm wide, glabrous to sparsely villous, petioles 1–5 mm long. Flowers in sessile spikes, bract and bracteoles shiny white, 0.7–1.5 mm long, glabr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cynodon Dactylon
''Cynodon dactylon'', commonly known as Bermuda grass, is a grass found worldwide. It is native to Europe, Africa, Australia and much of Asia. It has been introduced to the Americas. Although it is not native to Bermuda, it is an abundant invasive species there. In Bermuda it has been known as "crab grass" (also a name for '' Digitaria sanguinalis''). It is also known by various names as ''Dhoob'', ''dūrvā'' grass, ''ethana'' grass, ''dubo'', dog grass, dog's tooth grass, Bahama grass, crab grass, devil's grass, couch grass, Indian ''doab'', ''arugampul'', grama, wiregrass and scutch grass. Description The blades are a grey-green colour and are short, usually long with rough edges. The erect stems can grow tall. The stems are slightly flattened, often tinged purple in colour. The seed heads are produced in a cluster of two to six spikes together at the top of the stem, each spike long. It has a deep root system; in drought situations with penetrable soil, the root system c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flood
A flood is an overflow of water ( or rarely other fluids) that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrology and are of significant concern in agriculture, civil engineering and public health. Human changes to the environment often increase the intensity and frequency of flooding, for example land use changes such as deforestation and removal of wetlands, changes in waterway course or flood controls such as with levees, and larger environmental issues such as climate change and sea level rise. In particular climate change's increased rainfall and extreme weather events increases the severity of other causes for flooding, resulting in more intense floods and increased flood risk. Flooding may occur as an overflow of water from water bodies, such as a river, lake, or ocean, in which the water overtops or breaks levees, resulting ...

Aquatic Plant
Aquatic plants are plants that have adapted to living in aquatic environments ( saltwater or freshwater). They are also referred to as hydrophytes or macrophytes to distinguish them from algae and other microphytes. A macrophyte is a plant that grows in or near water and is either emergent, submergent, or floating. In lakes and rivers macrophytes provide cover for fish, substrate for aquatic invertebrates, produce oxygen, and act as food for some fish and wildlife. Macrophytes are primary producers and are the basis of the food web for many organisms. They have a significant effect on soil chemistry and light levels as they slow down the flow of water and capture pollutants and trap sediments. Excess sediment will settle into the benthos aided by the reduction of flow rates caused by the presence of plant stems, leaves and roots. Some plants have the capability of absorbing pollutants into their tissue. Seaweeds are multicellular marine algae and, although their ecological ...
