“…However, coastal wetlands are also severely threatened, and considered to be the ecosystem most sensitive to global sea-level rise (Morris et al, 2002;Wingard and Lorenz, 2014). Although the coastal zone only cover 4% of the earth total land area, this narrow region provides harbors for nearly one-third of the world's human population, and also provides critical habitat for organisms such as migratory waterbirds (MEA, 2005;Alfaro and Clara, 2007;Fitzsimmons et al, 2012). However, coastal wetlands have been suffering from serious degradation, alteration or loss due to intense anthropogenic activities (i.e., wetland reclamation, pollution and drainage) (Lemly et al, 2000;Newton et al, 2012;Cvetkovic and Chow-Fraser, 2011), and thus, coastal wetlands are listed amongst the most heavily damaged of natural ecosystems worldwide .…”
