Developing mangroves has long been a matter of interest to scientists. To properly plan mangrove development, it is necessary to assess the suitability of mangrove species. In this study, we evaluated the suitability of two mangrove species, Rhizophora stylosa and Aegiceras corniculatum, for the Nghe An province coastal area, Vietnam. The study area has 18 land units that were suitability assessment for the growth of R. stylosa and A. corniculatum based on 16 indicators of 4 criteria: (1) Soil salinity, (2) Soil mechanical composition, (3) Tidal inundation, and (4) Current status of saline soil and mangrove forests. The results show that: there are 5 land units are highly suitable (67.54 ha, 9.43%); 6 land units are moderately suitable (237.83 hectares, 33.22%); 2 land units are marginally suitable (31.2 hectares, 4.59%), and 5 land units not suitable (377.62 hectares, 52.75%) for the growth of R. stylosa. 6 land units are highly suitable (105.95 hectares, 14.8%); 7 land units are moderately suitable (232.31 hectares, 32.45%); no land units are marginally suitable; 5 land units are not suitable (377.62 hectares, 52.75%) for the growth of A. corniculatum. The research results are the scientific basis for expanding the area and developing suitable mangrove trees in the Nghe An province coastal area.
