The propagule starts to grow its sprout in the fruit while it is still on the mother tree. Typically Rhizophora mangle develops a one columnar stem which often soon starts to develop a few main branches. Rhizophora species generally live in intertidal zones which are inundated daily by the ocean. Morgantown, WV: Commune-Tech Associates. Bark gray or gray-brown, smooth and thin on small trunks, becoming furrowed and thick; inner bark reddish or pinkish. The most direct impact they have had on endangered waterbirds is the invasion of foraging and nesting habitat where none of the species will forage or nest (Cox and Allen, 1999). Wetlands. However, R. mangle has somewhat larger and shinier leaves than these other mangroves, and is further distinguished by its long and pencil-shaped ‘fruits’. As most mangrove propagules the propagules of Rhizophora mangle are viviparous and already develop a sprout on the mother tree. Compendium record. Agriculture Handbook Washington, 679. Rhizophora mangle (red mangrove); prop roots. As such, the development of rhizophores can be predicted to be important for the effective https://npgsweb.ars-grin.gov/gringlobal/taxon/taxonomysearch.aspx, USDA-NRCS, 2015. Scientific investiga- tions in more recent times have included those of Warming (1883), Karsten (1891), Schenck (1889), and Boergesen and Paulsen (1900). Trees tend to be of shorter stature and more spreading in shape on the seaward edge of stands or in areas of higher salinity. Technical Report 121. Mehlig U, 2006.

R. mangle propagules have been intentionally introduced. It is a valuable plant in Florida, Louisiana, and Texas coastal ecosystems. RhizophoramangleL.,oneofthemostcommonmangrovespecies,hasanaerialstructuresystemthatgivesit stability in permanently swampy soils. Waiohuli Keokea, Maui, Hawaii, USA. Gill AM; Tomlinson PB, 1969. As a facultative halophyte, R. mangle can tolerate waterlogged soils and high salinity in both water and sediment up to 90 ppt, but salinity is not a requirement for growth (Hill, 2001), and higher salinity can reduce establishment (Elster et al., 1999).

Propagules of Rhizophora mangle are easy to identify for beginners as they are brown at the lower third of the propagule. In fact, these structures, known as “aerial roots”or “stilt roots”, have proventobepeculiarbrancheswithpositivegeotropism,whichformalargenumberofrootswhenincontact with swampy soils. R. mangle is a tropical and subtropical American species, native to a wide area on both eastern and western coasts: on the Pacific, from Baja California, Mexico, to northern Peru, and on the east, from North Carolina to Florida (USDA-NRCS, 2015) and around the Gulf of Mexico, the Caribbean, and along northern South America to the north east of Brazil (USDA-ARS, 2015). Rhizophora mangle excludes the salt in seawater at the root-substratum interface. Mean temperature ranges for optimal growth of R. mangle are 21.6°C to 25.6°C (Duke, 1983) and cold temperatures limit the native range to below the latitudes of 28°N and 28°S (Hill, 2001).

Seagrape Cocoloba uvifera This familiar shoreline tree is easy to identify by its large round leathery leaves. Studies on the growth of Red Mangrove (Rhizophora mangle L.). Red Mangrove inhabits the deepest water of the four species, and its fruits are the most curious-looking. Tropicos database. The colors of the blossoms are usually white and yellow which car vary from pale yellow to dark yellow. Family: Rhizophoraceae. One of the four “mangrove trees” of Florida, the magnificent red mangrove is a frequent native, that grows as a shrub or a tree to 60 feet tall. Stand structure and productivity of the introduced Rhizophora mangle in Hawaii. Laie Kihei, Maui, Hawaii, USA. R. mangle is a fast growing species that can tolerate the wide range of environmental conditions found in coastal areas, although Krauss and Allen (2003) report that low salinity combined with reduced light, or simply low sunlight alone, appear to favour R. mangle growth. Kovacs JM, 1998. This first information on complexity and polarity was important to guide solvent system testing. Gainesville, Florida, USA: Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida. https://plants.sc.egov.usda.gov. Extracts from R. mangle are reported to have various medicinal uses, including as a treatment for diarrhea, dysentery, fevers, eye ailments, skin disorders and a range of other diseases, though their effectiveness is not verified, but research does show that bark extracts reduce gastric ulcers, and have antimicrobial and antioxidant properties (Berenguer et al., 2006). In fully submerged conditions there is an absence of oxygen, and one of the most visible adaptations are root adaptations, with R. mangle developing prop roots from the stem or trunk of the plant from 2 to 4.5 m above the substrate (Duke, 1983), whereas other species rely on roots growing upwards from under the substrate. Invasive mangrove removal and recovery: food web effects across a chronosequence. Egler (1948) describes the processes involved in the dispersal and establishment of mangrove seedlings. The propagules eventually fall from the parent plant, but if submerged at the time, they can float for more than a year in seawater until they settle on suitable strata (Hill, 2001). A further distinct record from Angola (Duke, 1983) requires verification, and may refer to R. racemosa. It has arching aerial roots which form stilts and trunks creating the dense, soil stabilizing tangles that the mangrove is known for. Physical control options are expensive but have proved to be moderately to highly effective in Hawaii, where cutting by hand or with machines and dredging all reduce tree numbers and allow native species to return (Allen, 1998). Phenology of the red mangrove, Rhizophora mangle L., in the Caeté Estuary, Pará, equatorial Brazil. Allen JA, 1998. Rhizophora mangle (red mangrove); small plant. The abundance of fruit set is noted to be markedly seasonal in southern Florida, with maximum fruit production occurring in the autumn (Gill and Tomlinson, 1969). R. mangle tends to prefer full sun, but seedlings can survive in the understorey until a gap forms (Hill, 2001). It is also one of the tallest, growing more than 22 m. It is easily identified by its "walking" stilt roots that can grow as high as 4.5 m above ground (PUCNCPP, 1983b). September, 2009. Rhizophora mangle grows on aerial prop roots, which arch above the water level, giving stands of this tree the characteristic "mangrove" appearance. Fort Pierce, Florida, USA: Smithsonian Marine Station at Fort Pierce. The wood of the trunk has a high densite which makes it very attractive for industrial, more details about the usage of Rhizophora mangle can be found at "usage". 35-46. Title Tropical Timbers of the World. Rhizophora mangle is often the most seaward-growing species of mangrove in Caribbean and Atlantic mangrove forests (SMSFP 2001b). Biotropica, 3(1; 2):63-77; 109-124. Mangle Colorado. Rauzon and Drigot (2003) report the results of 20 years of work using thousands of volunteer hours and more than US$2.5 million of contracted labour to remove 8 hectares of R. mangle in a fishpond complex in Hawaii, using hand tools, chainsaws and heavy equipment. Its most prominent feature is an array of aerial stilt roots (props) arising from the main trunk at 2.0-4.5 m height. Known negative impacts include reduction in habitat quality for endangered waterbirds, affecting the nesting habitats of some endangered waterbirds, including the Hawaiian duck (Anas wyvilliana), Hawaiian coot (Fulica alai), Hawaiian stilt (Himantopus mexicanus knudseni) and Hawaiian moorhen (Gallinula chloropus sandvicensis) (Chimner et al., 2006), reducing native species in fish ponds (Pratt, 1998) and anchihaline pools that have a large algal component and a highly specialized and vulnerable fauna, overgrowing native Hawaiian archaeological sites (Fronda et al., 2008), and causing drainage and aesthetic problems (Allen, 1998). They grow up to 30 m (100 ft) tall often with aerial stilt roots, but in more marginal habitats are shorter, more branched and scrubby. Current extent and historical expansion of introduced mangroves on O'ahu, Hawai'i. It is also one of the tallest, growing more than 22 m. It is easily identified by its "walking" stilt roots that can grow as high as 4.5 m above ground (PUCNCPP, 1983b). Effects of herbicides on seedlings of the red mangrove, Rhizophora mangle L. BioScience, 23:361-364. R. mangle has also been reported as present in Queensland, Australia. Laie Kihei, Maui, Hawaii, USA. It is also worth noting that in its native range, R. mangle stands are also being invaded by other exotic species, for example by exotic mangroves in Florida (Fourqurean et al., 2010). The stilt roots of Rhizophora mangle Mangroves can help us solve some of the world’s most pressing environmental problems, including improving fish stocks and protecting cities from hurricanes. Removal of alien red mangrove from Kaloko-Honokohau National Historical Park. MacKenzie RA; Kryss CL, 2013. Assessing mangrove use at the local scale. Invasive mangroves also facilitate the persistence and spread of introduced species, which may ultimately impact the 500 or so endemic estuarine and marine species in Hawaii (Demopoulos and Smith, 2010).

Natural dispersal of R. mangle propagules is facilitated by tides and seasonal flooding (Murray et al., 2003) and severe storms (Proffitt et al., 2006). R. mangle is also used for ecological and landscape maintenance and stabilization, and is commonly used to stabilize coastal mudflats and reduce erosion (Cox and Allen, 1999). Red mangroves (Rhizophora mangle), identified by their stilt-like roots, and the black (Avicennia germinans) and white mangroves (Laguncularia racemosa) thrive in tidal waters, where freshwater from the Everglades mixes with saltwater. R. mangle can survive under permanent submersion, resulting from flooding, due to its unique anatomy and physiology (Hill, 2001). It can colonize areas rapidly and form dense, naturally monospecific stands that outcompete other species, and as such is an essential component of native ecosystems, though it is occasionally noted as weedy where native. http://www.tropicos.org/, Steele O C, Ewel K C, Goldstein G, 1999.

R. mangle removal results in gradual changes in community composition and an increase in total faunal abundance, a decrease in subsurface deposit feeders, and an increase in suspension-feeding worms (Siple and Donahue, 2013). R. mangle flowers are hermaphroditic, containing both male and female sex organs, and pollen is wind dispersed (Mehlig, 2006), both of which may increase the high incidence of self-pollination, leading to inbreeding depression within populations (Proffitt et al., 2006). In Mexico it has been planted to improve coastal beach habitats for native fauna and reduce the effects of erosion from severe weather or tidal forces (Mendez Linares et al., 2007), and has also been planted by the aquaculture industry to improve coastal habitat for fisheries and shellfish harvest (Kovacs, 1998).

Description Members of the genus Rhizophora are very similar to each other in morphology. It is considered that the lower effectiveness of non-indigenous predators in Hawaii may be one reason for the high rate of R. mangle establishment there (Steele et al., 1999). Rhizophora americana Nutt. R. mangle is opportunistically invasive, with a high potential to invade alien environments and is not recommended for planting outside its natural range (Duke and Allen, 2006). Rhizophora mangle is an evergreen small shrub to medium-sized tree, growing up to 20 m in favourable conditions. Basal treatments of triclopyr are also reported to be effective on R. mangle.

R. mangle forests also provide habitat for other exotic species including burrowing predators which impact native benthic communities (Siple and Donahue, 2013). Bark grey or grey-brown, smooth and thin on small trunks, becoming furrowed and thick on larger ones. Rhizophora mangle develops the for Rhizophora species typical stilt roots or prop roots. Rhizophora mangle. Fibres from the branches and roots have been used to make fishing lines. Hill (2001) reports that R. mangle propagules in Florida are consumed directly by the spotted mangrove crab (Goniopsis cruentata), the mangrove land crab (Ucides cordatus), the coffee bean snail (Melampus coffea) and the ladder horn snail (Cerithidea scalariformis), and leaves are eaten by the mangrove crab (Aratus pisonii), the spotted mangrove crab (G. cruentata), the blue land crab (Cardisoma guanhumi), and various insects. Many of the habitats typically occupied by mangroves elsewhere in the tropics, as in Hawaii, had no tree cover at all, and as such they represent an entirely new life form in the ecosystems they invade, causing dramatic effects on plant community structure. R. mangle is easily recognized from most other species by the mass of peculiar, branching, curved and arching stilt roots that enable the trees to spread in shallow salt and brackish water, forming dense, impenetrable thickets. Rhizophora mangle (red mangrove); habitat, with young plants. R. mangle is one of approximately 35 species of true mangroves, with another 60 or more species of mangrove associates (Hill, 2001). http://www.traditionaltree.org.
