The first intensive ecological study of coastal vegetation including mangrove, littoral and peat swamp forests after the 2004 tsunami catastrophe in Northern Sumatra was conducted from January to December 2005 where 16 sampling sites along 2960-km coastline in Northern Sumatra were selected. In each site, one hectare quadrat plot was established and divided into 10 m x 10 m subplots where all standing trees of ≥ 2 cm diameter at breast height (DBH) were identified to species level and measured DBH. Overall 54,871 standing trees were recorded in 16 sites comprising 84 species in 65 genera and 37 families. Mangrove trees Rhizophora apiculata and R. mucronata were widely distributed and most dominant in most sampling sites. This indicated that these species have stronger resilient compared to other species. The highest value of Shannon-Wiener index and Evenness index was 3.03 and 0.85, respectively. It means that some of sites have rich in biodiversity which harbors various species of plants. Subsequently, undisturbed coastal forests including mangroves, littoral forests and peat swamp forests characterized by dense stands, mixed species and structures play an important role in coastal protection against tsunami. Therefore, the coastal vegetation is needed to conserve the biodiversity and to maintenance the production capacity as part of sustainable and longlasting vegetation bioshield.
