Abstract

The method of quantification of species diversity and distribution by the Shannon- Wiener Index (H’), Index of Similarity (SI), Importance Value Index (IVI), Niche width (bi), Complexity Index (CI), Spatial Distribution (Abundance/ Frequency - A/F) was used to quantify the diversity and distribution of woody true mangroves in Dong Rui, Xuan Thuy national park and Hau Loc along northern coast of Vietnam. The results showed that the species diversity and the structural complexity of the woody true mangrove vegetation at the study sites are relatively low, descending from Dong Rui (H = 1.13; CI = 12.15) to Xuan Thuy National Park (H = 0.62; CI = 11.33) and Hau Loc (H = 0.35; CI = 25.54). However the woody mangrove species compositions of the s...
