Additionally, the rivers in these areas mean that there are large numbers of fish in the waters. Many swamps are even covered by water. They exist near freshwater lakes and the lower portions of a river. 1 INTRODUCTION. Ratargul Swamp Forest is a freshwater swamp forest located in Gowain River, Fatehpur Union, Gowainghat, Sylhet, Bangladesh. Anthropogenic threats to tropical freshwater swamps are highly variable and depend … Litsea, Parastemon, Calophyllum, Hopea, Alseodaphne, and Chorea spp.) These trees have vast rooting system and form a close canopy. Some animals live in the low-oxygen water (some fish, crayfish, shrimp, tadpoles, insect larvae, etc. Freshwater swamp forests, or flooded forests, are forests which are inundated with freshwater, either permanently or seasonally.They normally occur along the lower reaches of rivers and around freshwater lakes.Freshwater swamp forests are found in a range of climate zones, from boreal through temperate and subtropical to tropical.. Over very short distances, changes both in the structure and composition of the forest is evident. As their species were found in all the forest clusters: disturbed freshwater swamp forests, intact freshwater swamp forests and mangrove‐freshwater transition zone; it emphasizes the widespread and dominant features of tropical forests (Gentry, 1988). These three swamps are from very different places in the world, but still fit the same definition, showing the incredible diversity of swamps all over the world. of Bangladesh. Image of agriculture, flood, park - 85857348 They normally occur along the lower reaches of rivers and around freshwater lakes. Swamp forests are home to a host of plants and animals. Marshes develop along the edges of rivers and lakes. These are swamps in which forests are saturated with freshwater during part of the year, or permanently. Swamps are warm, wet areas that are teeming with both animal and plant life; the water-logged land in swamps is often heavily forested, with trees like cypress and tupelo. Animals like mink, raccoons, opossums, muskrats, beavers, frogs, turtles and lots of species of birds and insects are common in marsh lands. It is the only swamp forest located in Bangladesh and one of the few freshwater swamp forest in the world. Located in Gowainghat, Sylhet, Ratargul is freshwater swamp forest. They are often named for the type of trees that grow in them, such as cypress swamps or hardwood swamps. The disturbed forest groups (both the disturbed freshwater and transition zones) had higher frequencies of indicator species due to the … past, freshwater swamp forests also existed in Jurong, Ang Mo Kio, Mandai, and Pulau Tekong, but were cleared during the course of development in Singapore (Corner, 1978). Most of the animal species found in mangroves also occur in other environments, such as beaches, rivers, freshwater swamps or in other forest formations near water. Ratargul is a freshwater swamp forest situated in sylhet, Bangladesh. On the whole, animal species strictly confined to mangroves are very few (crabs have a maximum number of species in mangroves). Methods: A total of 11 permanent sampling units (UM) were established by defined strata: five in the mangrove, two in swamp forest, two in freshwater marshes and two in the flooded pasture. Extensively depleted by clearing in floodplain habitats and threatened by coastal development elsewhere. The middle picture is of the Ratargul Swamp Forest in Bangladesh. The rich plant life in the river swamps attracts plenty of insects, which in turn attract birds and animals. Freshwater swamp forests are forest habitats inundated with fresh water via rivers and streams, with only a thin layer of peat potentially present (Whitmore, 1998).This ecosystem is a relatively understudied and unappreciated habitat type in Southeast Asia, in comparison with other wetland habitats such as mangrove swamps or peat swamp forest (Dudgeon, 2000a; Yamada, 1997). The specific animals present depend on whether the swamp is a freshwater swamp or a saltwater swamp. A swamp is an area of land permanently saturated, or filled, with water. Swamp Animal Printouts. Freshwater swamp forest occurs on permanently or seasonally flooded mineral soils, often in zones up to 5 km wide, along rivers or around freshwater lakes. This tropical rainforest type is very rich in tree species (eg. Swamp forests are better known as freshwater swamp forests or flooded forests. PLANT LIFE IN SWAMP FORESTS. The forest is naturally conserved under the Department of Forestry, Govt. Topography and water supply are the two most important features in determining the distribution of freshwater swamps. Four main physiognomic types of freshwater swamps can be distinguished: (i) herbaceous swamps, (ii) shrub swamps, (iii) savanna/woodland wetlands, and (iv) swamp forests. There are two main types of swamps: freshwater swamps and saltwater swamps. The picture to the right is the Okefenokee swamp in Georgia. This is the only Swamp forest in Bangladesh and one of the few freshwater swamp forests in the world. The wet season is a lean period, and hunting of animals, which might have filled the gap, is no longer available to most people. The coastal forests are diverse, including moist lowland forest, freshwater swamp forest, mangrove zone, etc. Freshwater swamp forest beside the Matan River. They are filled with water most or all of the year, and often form a 1- to 2-mile wide band extending from the river marshes to the bottomland forests along creeks that flow into the river. ), some animals live at the surface of the water (like alligators, caiman, nutria, etc. For example, some plants have evolved unique root systems such as Xylopiafusca and Alstoniapneumatophora. The evergreen forest goes under 20-30 feet water in the rainy season. They are distinguished from other types of wetlands such as marshes and bogs, by the dominating presence of trees and shrubs. Apart from fish, there is an abundance of aquatic life that includes mollusks and freshwater crustaceans. Thus, forestry is an important economic activity in the area. Thus, freshwater swamps are often described as low-lying forested regions that absorb floodwaters and run-off from the land around them. and animals such as Argus pheasant, Proboscis monkey, Orang utan (highest density recorded anywhere), False gharial. Swamp forest occurs inland of the mangroves in freshwater conditions. How Swamp forest is formed. An extensively distributed but locally restricted group of assemblages sharing floristic affinties with Coastal Swamp Heaths and Coastal Floodplain Wetlands. The flora and fauna of the forest have adapted to cope with constant flooding.

However examples on sandplains are represented in reserves. River of Grass. Freshwater swamp forests, or flooded forests, are forests which are inundated with freshwater, either permanently or seasonally. There are very few trees in freshwater marshes. Unlike freshwater, more than 85% peat swamp forests are located in Southeast Asian region, such as Indonesia, Malaysia, Brunei and Papua New Guinea (4). ... swamp animals are little affected by wetland conditions except as those conditions affect the species of trees growing in the swamp. The forest resources are intensively exploited manually by artisanal loggers and hunters, and on a large industrial scale in states like Ondo, Edo, Delta, Bayelsa, Rivers, and Cross River. Swamps are dominated by trees. Freshwater swamp forests – the forested wetlands occurring along rivers and lakes – are home to various endemic and endangered species with 33% of birds and 45% of mammals either threatened or endangered on the IUCN Red List 3, and with most of the insect fauna unknown. The area of the forest is about 504 acres. These ecosystems are under threat worldwide from habitat destruction, pollution, and climate crisis. The freshwater swamp forest is a habitat that is rich in biodiversity, teeming with plants and animals that are unique to it. Southern deepwater swamp forests are a type of freshwater wetland often found along the floodplains of large rivers. The original vegetation in these freshwater swamp forests may have been Melaleuca-dominated (BAP 1995). In the Niger Delta, the freshwater swamp is situated between the lowland rain forest in the north and the mangrove swamp in the south. Even the NSSF has not been completely spared, as large areas of freshwater swamp forest were cleared or submerged during the expansion and construction of the Upper Seletar Reservoir. It is 26 kilometers away from the central town of Sylhet. Orangutans can live in various types of forests, ranging from the forest, hills and lowlands, watersheds, freshwater swamp forest, peat swamps, dry land on mangrove swamps, to the mountain forests. Freshwater swamp forest consists of flood-tolerant evergreen trees of about 10–12 m in height. Photo about The freshwater swamp forests of Sri Lanka form unique ecosystems, interesting to discover, Nisala Sewana Park. Freshwater swamp forests are found in a range of climate zones, from boreal through temp Tropical freshwater swamps support a wide biological diversity and provide ecosystem services that benefit local dependent communities. Freshwater swamp forest in Bangladesh Peat bogs are freshwater wetlands that develop in areas with standing water and low soil fertility. In many countries however, the mangroves represent the last refuge for a number of rare … On the left, the picture is of Patanal, the world's largest freshwater wetland, in Brazil. Freshwater swamp forests are found on in valleys and along water courses that are subjected to periodic inundation by fresh water. Animals that live in swamps include alligators, amphibians, shellfish, bears and panthers. 2.4 Freshwater swamp forests. (NDES, 1998). Peat swamp forest occurs when accumulation of acidic peat layer happens in freshwater for many years, and therefore freshwater swamp forest turns into the peat swamp forest (7). Many different species of mammals, birds, reptiles, amphibians and fish live and thrive in swamp … These forests are usually the next forest type to develop behind the mangrove swamps.
