Assessment of mangrove biodiversity along the Lach Van river in Dien Chau district, Nghe An province
Keywords:Biodiversity index, Lach Van river, mangrove forest.
The mangrove forest along Lach Van river in Dien Chau distric, Nghe An province has dramatically
decreased that resulted in biological diversity reduction and negative consequences for local people. Therefore to conduct research to survey and assess the biodiversity of this area for proper protection and recovery of this forest is important. In our study, field surveys and plot sampling were conducted for collecting data to assess plant species richness using Shannon diversity index and Simpson dominance index. Preliminary results revealed 16 species of 13 taxonomies in the mangrove along to Lach Van river. The structure of species composition is relatively poor, this is a typical character of mangrove ecosystem in central Vietnam region. Shannon diversity index (H'mean = 0.590) and Simpson dominance index (Dmean = 0.640) indicated relatively low biodiversity.
