Regeneration and colonisation of mangrove on clay-filled reclaimed land in Singapore

Abstract

A mature mangrove community was preserved at Pasir Ris during the reclamation of its foreshore by maintaining a channel (river) so that the plot could be subjected to inundation frequency of 40 to 50 times per month . By subjecting the embankments of the river and another plot of vacant reclaimed land adjacent to the mature community to a similar frequency of inundation, new mangrove communities comprising Avicennia spp and Sonneratia alba were regenerated . When the depth of the mangrove soil increased proportionately with time, succession by another seral community (Rhizophora spp) occurred . Factors affecting the development of the mangrove soil and its nutrient accumulation over time, and the regeneration of new mangrove communities through colonisation by different plant and animal species are discussed . 23

Temporal mangrove dynamics in relation to coastal development in Pacific Panama

“…This would indicate that the mangrove is recovering from the disturbance caused and will continue to rejuvenate into the future. The pioneering nature of L. racemosa and the preservation of some mangrove during this coastal development work no doubt aided the survival and continued growth of mangrove forest in the bay (Bacon, 1975;Lee et al, 1996;Tomlinson, 1999). The mangrove in the bay regenerated through natural processes and was not assisted by reforestation and this disputes Farnsworth and Ellison (1997) who stated that mangrove recovery is universally slow after disturbance unless assistance is given.…”

Effects of sediment burial disturbance on seedling survival and growth of Suaeda salsa in the tidal wetland of the Yellow River estuary

“…As the level of burial increases over the threshold, the response might be a deterioration in plant growth and vigor, and ultimately failure to survive (Zhao et al 2007). Many studies on the responses of burial to plant growth appear in the current literature, but these reports focused mainly on arid and semi-arid dune (Sykes and Wilson 1990;Maun 1996;Brown 1997;Liu et al 2006;Yang et al 2007;Zhao et al 2007;He et al 2008), coastal and lacustrine dune (Maun 1994(Maun , 1998Maun et al 1996;Franks and Peterson 2003), salt marsh (Deng et al 2008) and mangrove marsh (Lee et al 1996;Terrados et al 1997;Thampanya et al 2002), and corresponding studies on tidal wetlands are very scarce.…”

Mangroves and Sediment Dynamics Along the Coasts of Southern Thailand

“…On the positive side, sediment accretion may open new habitat for mangroves to colonize (e.g. Purba 1991; Lee et al 1996;. In contrast, sudden high sedimentation events may occur during heavy rainfall and can cause reduction in growth and mortality of mangroves if their aerial roots are blocked (Hutchings & Saenger 1987;Ellison 1998).…”

“…The first two species have been considered as pioneer species colonising newly accreting mud flats (Tomlinson 1986;Lee et al 1996;) and the last is a dominant, late successional species widely used for rehabilitation programs (Havanond 1995;Field 1995). Knowledge of species-specific sensitivities to sedimentation will provide a better understanding of natural processes of space occupation by mangroves (i.e.…”
