TAILIEUCHUNG - Assessment of the changes in the structure of mangroves based on stand age in Bang La, Hai Phong, Vietnam

The paper results showed that the more than ten years mangrove community is a stable forest biome. Mangroves from 10 years old should be planned with different species to increase the diversity in species structure and enhance the ability to stabilize the community and withstand changes in coastal habitats. | Vietnam Journal of Marine Science and Technology 2023 23 4 397 408 Vietnam Academy of Science and Technology Vietnam Journal of Marine Science and Technology journal homepage jmst Assessment of the changes in the structure of mangroves based on stand age in Bang La Hai Phong Vietnam Quang Van Pham1 2 Linh Manh Nguyen1 2 Hung Manh Vu1 1 Institute of Marine Environment and Resources VAST Vietnam 2 Graduate University of Science and Technology VAST Vietnam Received 18 April 2023 Accepted 8 July 2023 ABSTRACT The mangrove forest area in Bang La Hai Phong is 370 ha and tree density is 5885 individuals ha distributed along the upper bank of the Van Uc River with high tidal flats. Detected 20 species of mangrove plants belonging to 19 genera 16 families and two divisions. The survey results show that the Bang La mangrove forest ecosystem has three forest types the forest community is older than 15 years old the forest community is from 10 to 15 years old and the forest community is less than 10 years old. Kandelia obovata Sonneratia caseolaris and Rhizophora stylosa is the dominant plant species. In each forest biome of different ages there are different dominant species. The general composition formula for the study area is Ko Sc Ks Ai Ac. The paper results showed that the more than ten years mangrove community is a stable forest biome. Mangroves from 10 years old should be planned with different species to increase the diversity in species structure and enhance the ability to stabilize the community and withstand changes in coastal habitats.
