Species composition, age distribution, and their relationship with land height from the datum line (LH) of the Sonneratia caseolaris stand, which grows in the Lam River estuary in Vietnam, were surveyed to obtain fundamental knowledge that aimed at contributing to mangrove restoration. The data gathered on the sandbar consists of three mangrove species and one mangrove associate species, with one non-mangrove species, and were divided into three communities. In terms of the age distribution of the S. caseolaris–Aegiceras corniculatum community, the tree-phase densities for both species are lower than those exhibited by younger phases. In its succession, the seedlings of S. caseolaris and A. corniculatum are primarily recruited at the mean tide level (MWL) in the early stages. Then, A. corniculatum expands to the lower tide zone primarily on mud flat bare land. For both species, full irradiance on the bare land in the low tide zone below MWL is crucial for growth, but S. caseolaris, which propagates by releasing small seeds, can barely survive in the low tide zone because its seeds are easily flushed away. In contrast, A. corniculatum, which propagates using crypto-viviparous seedlings, has a higher survival rate in the low tide zone. As a result, the LH of seedlings of A. corniculatum distribution is significantly lower than that of the distribution of S. caseolaris trees (p < 0.05). It is important to provide appropriate environmental conditions for forest restoration in order to promote succession. The findings from the current study on population dynamics related to LH and tidal conditions are expected to be applied to platforms for S. caseolaris stands and mangrove restoration.

物种组成，年龄分布，以及它们与从的基准线（LH）土地高度关系海桑立场，生长在林河口越南，进行了调查获得基础知识，旨在促进红树林修复。在沙洲上收集的数据包括3种红树林物种和1种红树林伴生物种，以及1种非红树林物种，并分为三个群落。就干酪乳杆菌（S. caseolaris–Aegiceras corniculatum）群落的年龄分布而言，两种树的树期密度均低于年轻阶段的树期密度。依次为干酪乳杆菌和山茱A的幼苗主要是在初期以平均潮位（MWL）招募。然后，A。corniculatum主要在平坦的裸露土地上扩展到低潮区。对于这两个物种，MWL以下低潮区裸露土地上的充分辐照对于生长至关重要，但是通过释放小种子繁殖的干酪乳杆菌在低潮区几乎无法生存，因为其种子很容易被冲走。相比之下，使用隐性活体幼苗繁殖的角果曲霉在低潮区具有较高的成活率。结果是，A. corniculatum分布的幼苗的LH显着低于S. caseolaris树的分布（p <0.05）。重要的是为森林恢复提供适当的环境条件，以促进演替。当前有关LH和潮汐条件的种群动态研究的结果有望应用于干酪乳杆菌林分和红树林恢复的平台。
