mangrove trees name

Mature propagules have light green or yellow cotyledon and they can be collected from trees or gathered from the forest floor and water. Synonyms: Rhizophora candelaria, Rhizophora conjugata, Status: Rare; a few individuals are found in the northern islands. Red mangorve prop roots emerging from the water at Weedon Island Preserve in Pinellas County, Florida. They can be plucked from mother trees or freshly fallen propagules can be used for planting. In this method of reproduction, seeds germinate and develop into seedlings while the seeds are still attached to the parent tree. Petals are four in number, light yellowish, densely haired along the margin. Flowers open only in the late evening, lasting one night only; nectar is plenty in the calyx. Dhivehi name: Baru. Propagules detach with calyx, buoyant and dispersed by currents. It is very easy to dismantle these seeds but it is very difficult to put the seeds back together and because of this reason it is popularly called as the monkey puzzle nut. Flowers are large, 8 to 10 cm wide with prominent red and white stamens; calyx six to eight lobed and green coloured and petals are red. The black mangrove, usually of moderate height, sometimes grows 18 to 21 metres (59 to 69 feet) tall. Plants of mangroves are generally divided into two groups, namely, i) true or exclusive mangroves species and ii) associated mangrove species. Male spike is catkin like in appearance, yellowish and up to 7 cm long. In the Maldives, it is used for boat building and house construction. Our editors will review what you’ve submitted and determine whether to revise the article. It is present in two to three rows along the boarder of a large lagoon, which is still connected to the sea by a channel. Status: Rare; a single tree is observed in Male. Mangrove forests are among the most productive terrestrial eco systems. Ecology, propagation and management: It is normally found in the landward zone of mangrove forests and grows well in well-drained medium to heavy textured soil. It also avoids or reduces soil erosion. For this purpose, mangrove species have specialized above ground roots called breathing roots or pneumatophores. Breathing roots: Underground tissue of any plant requires oxygen for respiration and in mangrove environment, oxygen in soil is very limited or nil. These roots also have many pores through which atmospheric oxygen enters into the roots. Status: Occasional; restricted to northern islands. Bark is whitish to greyish or yellow-green in colour, smooth, often powdery and scaly. Physically, they serve as a buffer between marine and terrestrial communities and protect shorelines from damaging winds, waves, and floods. It is observed only in Fuvamulah island, where 10 to 12 trees are found growing on the landward portion of a brackish water lagoon (kulhi). Flowers are white or pinkish-white in colour and 0. Above-ground breathing roots are knee shaped and small buttress can be seen at the base of the stem. Status: Occasional; restricted to northern islands. Petals are purplish or brown in colour. It is also sold in the market. Common name: Grey mangrove. They are (a) river dominated, (b) tide dominated, (c) wave dominated, (d) composite river and wave dominated, (e) drowned bedrock valley mangroves and (f) mangroves in carbonate settings (Thom, 1984). Mangroves are a family of about 70 different species of trees worldwide. One tree species, Avicennia integra, is found only in Australia - in the Northern Territory, east of Darwin. Uses: It is one of the most favoured timbers in the Maldives. They can be collected from trees or gathered from ground and water. It is easily propagated by propagules. These seeds are kept in brackish water for about five days and most of them sink in two days and sprout in five days and then again float with extended roots. Larger wood is sometimes used in boat building. Nursery raised seedlings of about 20 to 35 cm in height, which is attained in about ten months, can be used for outplanting. Normally nursery-raised seedlings are used for planting. Local women are reversing the trend, in a community conservation initiative that combines tree-planting with microfinance. They can be planted by inserting one-third of their length into the mud. Description: A small- to medium- sized sized, evergreen tree 8 to 10 m tall with open spreading crown, horizontal branches and slender twigs. Inflorescence is a single flowered pendulous cyme and axillary in position. …for example, are fringed with mangrove forests, in which the dominant species—called, Some lateral roots of mangroves become specialized as pneumatophores in saline mud flats; pneumatophores are lateral roots that grow upward (negative geotropism) for varying distances and function as the site of oxygen intake for the submerged primary root system. Collected seeds should be subjected to floating test and seeds that float are viable. Mangrove, any of certain shrubs and trees that belong primarily to the families Rhizophoraceae, Acanthaceae, Lythraceae, Combretaceae, and Arecaceae; that grow in dense thickets or forests along tidal estuaries, in salt marshes, and on muddy coasts; and that characteristically have prop roots—i.e., exposed supporting roots. Bark is used for tanning fishing nets. Vivipary: Saline water, unconsolidated saline soil with little or no oxygen is not a conducive environment for seeds to germinate and establish. Description: A medium sized, erect, evergreen tree capable of growing to a height of about 20 m but trees found in the Maldives are only about 5 m tall. Seedlings, which are raised in the nursery from seeds and about 40 cm in height, can be used for outplanting. Status: Occasional; found growing as pure stand or mixed with Bruguiera spp. They grow luxuriantly in the places where freshwater mixes with seawater and where sediment is composed of accumulated deposits of mud. It is also a beach biome for tropical biomes that are bordering Oceans. It is propagated by seeds, wildlings and roots suckers. The only flowering trees that can exist between land and sea, mangroves derive their name from the Spanish mangle, a name which probably arose during the period of the Spanish colonisation of the Americas in the late 15th century. Bark is grey or dark grey in colour and sometimes longitudinally fissured. Rarely used in roof structures as purling. Poles are used for boat plying.

Inflorescence is one to a few flowered cymes, axillary in position and hairy. These naked propagules are used for plantation. In some countries it is a primary pulping species for paper industry and also used in traditional medicine to treat chronic ulcerous diseases such as leprosy. Number of seeds in fruits varies from four to ten and they are beautifully interlocked. Status: Common; found either as a dominant or co-dominant species in many of the mangrove ecosystem of the Maldives. It is also capable of growing well in waterlogged, deep, slushy and anaerobic soil. The term mangrove also applies to thickets and forests of such plants. Flowers are single and axillary in position. This dense tangle of roots acts as a net, holding and stabilizing shorelines. Mangroves grow in the tropics only and mainly in coastal areas. More than 95% survival has been reported with this method. They are best known for their distinctly pendulous long noses that they use to attract mates. Each fruit contains one oblong ovoid seed. Because of their high salt tolerance, mangroves are often among the first species to colonize mud and sandbanks flooded by seawater, but an increase in coastal development and altered land use led to a decline in global populations. Petals are five in number and white and brown coloured, two lobed and ending in two to four bristles. It enhances fishery productivity of the adjacent coastal waters by acting as a nursery ground for commercially important fish, prawn and crabs and supplying organic and inorganic nutrients. Flowers are creamy white, fleshy and fragrant. Timber is hard and strong and used for boat building. Ecology, propagation and management: It grows on light, medium and heavy soil but prefers silty clay soil and high- and mid- tidal zone for better performance. Timber is normally buried in sand at the edges of the sea for about six months to prevent easy decay. It also found in the form of pure stands. These areas normally receive limited amount of terrestrial sediment but they are rich in calcareous sediment or lime mud (marl). Description: An evergreen tree that grows up to 40 m in height in favourable sites, but most of the trees found in the Maldives are only 4 to 10 m tall. No seedling is noticed in the areas where the trees are found, indicating poor rate of natural regeneration. Select from premium Mangrove Seedling of the highest quality. Uses: Stilt root, which becomes smooth after removing the bark, was used in the past to make windows of traditional houses. Flowers are tiny, about 0.2 to 0.3 cm across, fragrant with yellowish-green calyx and greenish white petals. The lower branches, even though dry, are persistent and rigid, and as the trees grow very closely, they form impenetrable thickets. Female spike is shorter than male spike. This hardy tree acts as a natural windbreak, protecting us against tidal surges and purifying the surrounding water. In some areas it is found in the form of pure stands. When this propagule falls, the young root is in the correct position to be driven into the mud; the plant being thus rooted, the shoot makes its appearance. Mangroves are known best for the ecosystem they form on land. Description: A small or medium sized, low branching tree 6 to 12 m tall. Calyx is deeply four lobed and pale yellow. Inflorescence is a condensed cyme with five to ten flowers and axillary in position. Fruit is edible, which tastes like cheese, is eaten raw and relished by children and adult alike.

Heartwood is brown, red-brown or dark red brown in colour, coarse textured, fine grained, hard and strong and takes polish well but is nondurable. Each leaflet is ovate to cordate in shape, 7 to 10 cm long, shiny, green with curled margin and pointed tip (in X. granatum leaf tip is rounded). Ecology, propagation and management: It is capable of growing well in somewhat dry and well-aerated soil in the mid- and high- tidal areas of the intertidal zone. Flowers are small, 0.3 to 0.5 cm across, sessile, fragrant, pale-yellow in colour in condensed terminal flower head. High-quality charcoal is prepared from larger stems. Wood is light weight, less durable and small in size due to short and crooked trunk. Dye produced from the bark is very thick and paint like, which makes fishing lines water proof. These fruits are collected from the forest floor and used for direct dibbling in containers in the nursery since germination rate of naked seeds is very poor. Ecology, propagation and management: It grows well in the landward edge of mangroves where soil salinity is low. Mangroves are various kinds of trees up to medium height and shrubs that grow in saline coastal sediment habitats in the tropics and subtropics mainly between latitudes 25 degrees N and 25 degrees S. Such bosks are also part of the mangrove forest biome. Bark is pale grey to reddish brown in colour, smooth in young trees, deeply fissured in old ones and flaky at the bottom.

While the fruit is still attached to the parent branch, the long embryonic root emerges from the seed and grows rapidly downward. Synonyms: Ceriops candolliana, Rhizophora tagal. Its tolerance to aridity is also high. Wood is heavy and moderately durable but in contact with ground it decays in about two years. One of the characteristic features of this tree is that when branches and leaves are broken or bark is damaged it exudes a milky sap, which may cause intense pain and blistering, if it makes contact with skin. It is sometimes used for docking the boat for repair and poles are used for boat plying. Propagules are spindle shaped, 10 to 15 cm long, 0.5 to 1 cm in diameter, smooth, slightly curved, cylindrical and green to purplish-green in colour, which are buoyant and dispersed by currents. Rhizophora species generally live in intertidal zones which are … To overcome this, mangrove species have unique way of reproduction, which is generally known as vivipary. It is propagated by propagules. Petals are five, white in colour and arranged alternate to sepals. Bark is pale grey or brown, thick, hard and rough. Above-ground breathing roots are normally absent but in moist environments, small looping lateral roots may develop. It is not resistant to termites. Red mangrove trees get their common name from their, well, red roots. Mature fruits can be easily identified by their brown colour and each fruit contains 20 to 30 very small seeds which can be collected by gently pressing the matured fruits. It can be easily multiplied by propagules. are spindle shaped because hypocotyl penetrates the seed coat and elongates (called as viviparous propagules). Sprouting completes within three weeks and in ten months it grows to a height of 100 to 125 cm. Mangrove environment is highly dynamic and harsh and mangrove species are variously adapted to cope with these environmental conditions. Leaves are compound, alternate in arrangement and leaflets are two to four pairs. True mangrove species grow only in mangrove environment and do not extend into terrestrial plant community and are morphologically, physiologically and reproductively adapted to saline, waterlogged and anaerobic condition. Timber, which is hard and strong, can be used for boat building and carpentry work. While sowing, radicle (the part of plant embryo that develops into a root) side of the propagules is lightly pushed into wet soil.

Single stemmed, multi-branched tree with spreading or diffused crown. These seeds are placed in the container, keeping the radicle side down. However, it can tolerate soil salinity upto 35 ppt. Natural regeneration is very poor and no seedling is noticed. A hurricane-born mangrove island may bring its own soil to the sea. Mangrove Roots grow in large groups in the water, and they are everywhere in the biome. Propagules can be directly planted in selected fields by inserting them up to one–third of their length. Heartwood is very hard, heavy, strong and durable and resistant to wood-boring molluscs and termites. Only a very few seedlings are noticed. It is propagated mainly by nursery-raised seedlings. The most Mangrove families were found in the USA in 1880.

Use census records and voter lists to see where families … He attributes the problem to a handful of local residents as well as those from surrounding villages. Around 600 mangrove trees were cut down in Bulacan, Philippines - the site for a big reclamation (airport) project in Manila Bay. Nursery raised seedlings of about 30 cm can also be used for outplanting. By protecting mangroves, we can help protect the future of our planet. These roots are also covered with numerous pores, which allow air but not water to enter the root. They are characterized by vertically erect aerating branches (pneumatophores) extending up to 20 cm above the soil.

Leaves are simple, shiny, opposite in arrangement and inverted-egg shaped. Collected propagules are soaked in brackish water for a day to facilitate shedding of outer coat. Ecology, propagation and management: Grey mangrove grows luxuriantly in any position in the intertidal regions of estuaries, lagoons (called kulhi in Dhivehi), backwater etc. Description: Of all the species in nature, the mangrove is among the most fascinating and beneficial to humanity. Bark is whitish to greyish or yellow-green in colour, smooth, often powdery and scaly. Ecology, propagation and management: It is normally found in the places of mangrove wetlands where soil and running water salinity is low. Propagules can be directly planted by inserting one-third of their length into sediments. Matured propagules can be identified by the red collar in the cotyledon. This was about 75% of all the recorded Mangrove's in the USA. Matured propagules, which are green or purple tinted, can be directly planted by inserting them up to one–third of their length in wet soil and sprouting takes place within five weeks.

Nursery-raised seedlings 20 cm height can be used for outplanting. It is also considered as a timber tree. Propagation by wildlings is relatively less successful compared to nursery raised seedlings. These cuttings are kept in the nursery for rooting and rooted cuttings with 10 to 12 leaves are used for outplanting. Hence, propagules of grey mangrove look more or less like normal seeds in appearance and they are called cryptoviviparous propagules. The common mangrove grows to about 9 metres (30 feet) tall. This tree is native to coastal regions of India, Bangladesh, Thailand , Cambodia, and peninsular Malaysia. It is propagated by seeds and nursery-raised seedlings. In some plants buttress roots function as breathing roots and also provide mechanical support to the tree.

Common names: Blinding tree, river poison tree. Propagules can be stored for five days in buckets filled with brackish water. Uses: Wood, which is light weight and less durable, is not widely used. The seeds germinate in the fruit on the tree. They generally belong to five major families- Acanthaceae (genus- avicennia or black mangrove), Combretaceae (genus- conocapus or button wood ), Arecaceae (genus-nypa or mangrove palm), Rhizophoraceae (genus- rhizophora or red mangrove), Lythraceae (genus- sonneratia … Mangrove forests in the tropics and subtropics are identifiable by their dense tangle of prop roots that help the trees handle the rise and fall of the tides. Updates? The germinated Strategies Used Ecology, propagation and management: It grows well in deep soft mud, which is rich in humus. They are also rich in biodiversity and act as habitats for wildlife. Mangrove wetlands are normally classified into six types on the basis of the geophysical, geomorphological and biological factors. Ecology, propagation and management: It grows well in sandy soil with very low salinity and in these places gregarious monospecific stands with large trunk and profusely branched trees can be seen. In the Maldives, it is located mostly around very shallow depressions situated somewhat away from the shoreline. Nursery-raised seedlings 20 to 30 cm, which can be obtained within a period of ten months, can be used for outplanting. Seeds are buoyant and dispersed by currents. Seeds are not directly sown in the field. Leaves are 4 to 8 cm long with short petiole having a reddish-pink base. Mangroves are quite the resilient bunch. The first five types of mangrove wetlands can be seen on coasts dominated by terrigenous sediments (shallow marine sediment consisting of material derived from the land surface) whereas the last one can be seen in oceanic islands, coral reefs and carbonate banks. As in the case of other Bruguiera spp. The astringent bark yields a water-soluble tanning substance. Leaves are simple, opposite in arrangement, lanceolate in shape, about 7 to 12 cm long, shiny, dark green in colour with pointed apex. They are buoyant and float in the water for sometime before rooting themselves on suitable soil. Status: Rare; a few trees are found in the mangrove environment in some of the northern islands. Synonyms: Bruguiera eriopetala, Rhizophora sexangula. Mangrove forests have an important function in our ecosystem as natural coastal protection; the extended root systems of every mangrove tree are a nursery. Nursery-raised seedlings about 35 cm in height can be used for outplanting. Stems cuttings 20 cm in length and about 1 cm in diameter can be used for propagation. Image of plant, fresh, water - 115558592 Mangroves of the Maldives belongs to carbonate setting type and within this broad category mangroves of the Maldives are found in four different environmental conditions: i) in the fringe area of some of the islands, where wave energy and wind speed is less and brackish water is present due to mixing of seawater with the margin of the freshwater lens, ii) in between two islands, where the water is shallow and there is accumulated deposits of sediments, iii) along the borders of lagoon that is connected to the sea, iv) along the borders of lagoon that has lost connection to the sea but receives seawater periodically through seepage and v) in shallow depressions, where rain water accumulates. They can also be collected from trees. Daily dousing with water is necessary to prevent desiccation. Description: A medium to large sized, much branched, evergreen tree that can attain heights up to 30 m. Presence of well-developed buttresses, which develop into plank roots, is a characteristic feature of this species. Matured propagules are purplish-green in colour which can be collected from water or plucked from trees. The water rarely goes below 62, making it one of the flattest biomes in Biomes O' Plenty. Fruits are small, round and clustered. Sarah Griffiths - Panama - What lies beneath. They can be easily collected during the low tide and collected fruits can be kept in a heap for a few days to allow the outer skin to rot. These knee roots comprise a sponge like system of air chambers, which act as an air reservoir when the roots are submerged. Each fruit contains 20 to 30 small seeds. Uses: Main trunk provides a hard and durable timber. Mature fruits float and immature fruits sink and rot. It is characterized by the presence of numerous stilt roots, which are looping from branches and trunk bases and provide support to trees; they also function as air-breathing roots. Mangroves are a natural habitat for marine organisms and serve as a breeding ground for shrimp, crab and fish species. It is able to grow in places where seawater wet its roots regularly during the high tide. Fruits are sown in a slanting position in containers, keeping half of the fruit inside the mud. Heartwood is brown and red in colour with streaks. Fruits are buoyant and dispersed by currents and when the fruit is floating, the "keel" acts as a sail, aiding dispersal. It is considered as excellent firewood. Silt roots: In some mangrove species, roots diverge from stems and branches and penetrate the soil some distance away from the main stem as in the case of banyan trees. Leaf stalk is 3 to 5 cm long. Leaves are single, opposite in arrangement, leathery, yellowish-green and hairless above and silver-grey below with pointed apex. Description: A small, erect, evergreen tree 6 to 10 m tall with knee-like above-ground breathing roots. Small pieces of wood are used for docking the boats for repair. MANILA — On July 29, the San Miguel Corporation, the Philippines’ largest company by revenue, started planting 25,000 mangrove trees in a coastal area just north of the capital, Manila. Ecologically, they provide habitat for a diverse array of terrestrial organisms, and many species of coastal and offshore fish and shellfish rely exclusively on mangroves as their breeding, spawning, and hatching grounds. It is also favoured for carved objects such as tool handles (long knife, axe etc. No prominent above-ground breathing root is present (in a related species Xylocarpus granatum buttress and plank roots are present; in another related species Xylocarpus moluccensis buttress, plank and peg-like pneumatophores are present). It is also highly effective in storing Carbon dioxide from the atmosphere, thus contributing to the fight … Yellow Mangrove Tree, Here is some detailed information on mangrove trees. Status: Common; found along the boarder of closed and open lagoons both in the northern and the southern islands. These sprouted seeds can be used for sowing in containers in the nursery. Surface of the propagules is warty and ridged, buoyant and dispersed by currents. These seedlings are normally called as propagules and they photosynthesize while still attached to the mother tree. Bark is light grey to brown, flaky in old trees. Status: Occasional; found on the landward side of the mangroves in some of the northern islands.
