Abstract


Besides biodiversity values, Kien Thuy coastal mangroves (Hai Phong city) play an important role in sea dyke protection, coastal erosion prevention, natural disaster mitigation, climate change adaptation and livelihood improvement for local residents. Therefore, research on mangrove forest protection and development is of great practical significance in the context of increasingly complex climate change. Survey results of coastal mangroves in Kien Thuy district, Hai Phong city showed a diverse flora with 60 species belonging to 52 genera and 31 families of two higher vascular plant phyla Polypodiophyta and Magnoliophyta, among which Magnoliophyta dominated with 59/60 species (98.33%). In particular, one species is listed in Vietnam Red Book (EN) and 04 species are listed in IUCN Red List (LC). In terms of species composition, the Kien Thuy coastal mangrove ecosystem comprised of 11 species of official mangrove vegetation, 23 species of mangrove species and 26 species that spread from the inland to the coastal zones. Mangrove vegetation in the study area varied across 03 areas, 05 canopy layers, with quite high coverage but low density of regenerated trees due to the influence of sea waves. Consequently, trees should be grown before planting in the
 intertidal area.
