“…Crucially, however, previous studies have revealed high acrosssite variability in the processes that contribute to surface elevation change [32][33][34] , making assumptions of uniformity in processes across wetlands inappropriate. This highlights the need for site-specific data that accurately represent local processes to initialize, calibrate and validate site-specific wetland models, and to evaluate the outcome of different SLR scenarios 35,36 .…”

“…Field observations (e.g. Krauss et al 2003) and experiments using artificial structures (Young & Harvey 1996) support the idea that higher densities enhance sedimentation, but it is also possible that they lead to scouring and erosion (Furukawa & Wolanski 1996). Sediment accretion is one of the processes by which mangroves may raise the soil surface, thus responding to sea level rise (Cahoon & Lynch 1997), and may also contribute to the ability of mangroves to sequester carbon (Bouillon et al 2008).…”

Mangroves are intertidal ecosystems that are particularly vulnerable to climate change. At the low tidal limits of their range, they face swamping by rising sea levels; at the high tidal limits, they face increasing stress from desiccation and high salinity. Facilitation theory may help guide mangrove management and restoration in the face of these threats by suggesting how and when positive intra-and interspecific effects may occur: such effects are predicted in stressed environments such as the intertidal, but have yet to be shown among mangroves. Here, we report the results of a series of experiments at low and high tidal sites examining the effects of mangrove density and species mix on seedling survival and recruitment, and on the ability of mangroves to trap sediment and cause surface elevation change. Increasing density significantly increased the survival of seedlings of two different species at both high and low tidal sites, and enhanced sediment accretion and elevation at the low tidal site. Including Avicennia marina in species mixes enhanced total biomass at a degraded high tidal site. Increasing biomass led to changed microenvironments that allowed the recruitment and survival of different mangrove species, particularly Ceriops tagal.

“…This generally holds true for the environmental settings that dominated by rivers, tides with abundant sediment supply and waves on prograding coasts (Woodroffe 1992). However, land uplift or subsidence, groundwater influx, vegetation and soil processes, and whether the coast is prograding or eroding also play important roles in determining the extent of the landward migration (Krauss et al 2003, McKee et al 2007, Lovelock et al 2015.…”

Mangroves function as a natural coastline protection for erosion and inundation, providing important environmental services. Due to their geographical distribution at the continent-ocean interface, the mangrove habitat may suffer heavy impacts from global climate change, maximized by local human activities occurring in a given coastal region. This review analyzed the literature published over the last 25 years, on the documented response of mangroves to environmental change caused by global climate change, taking into consideration 104 case studies and predictive modeling, worldwide. Most studies appeared after the year 2000, as a response to the 1997 IPCC report. Although many reports showed that the world's mangrove area is decreasing due to direct anthropogenic pressure, several others, however, showed that in a variety of habitats mangroves are expanding as a response to global climate change. Worldwide, pole ward migration is extending the latitudinal limits of mangroves due to warmer winters and decreasing the frequency of extreme low temperatures, whereas in low-lying coastal plains, mangroves are migrating landward due to sea level rise, as demonstrated for the NE Brazilian coast. Taking into consideration climate change alone, mangroves in most areas will display a positive response. In some areas however, such as low-lying oceanic islands, such as in the Pacific and the Caribbean, and constrained coastlines, such as the SE Brazilian coast, mangroves will most probably not survive.
