Sample Survey forest data - Pomene National Reserve

This dataset documents a forest inventory conducted in the Pomene Reserve, Mozambique. The study used a fixed plot method, following the methodology of Mueller-Dombois and Ellenberg (1974), for the qualitative and quantitative assessment of tree and shrub vegetation. Sixty plots of 20 m × 50 m (1,000 m² each) were established, totaling a sampling area of 40,000 m² (4 ha) within a total study area of 200 ha, corresponding to a sampling intensity of 3%. The plots were georeferenced and demarcated using measuring tapes and ropes. All living individuals (except lianas) were numbered, and those with a Diameter at Breast Height (DBH) ≥ 10 cm had their measurements recorded. The floristic sampling followed two phases: the first (June 9–13, 2024) focused on marking sampling points and recording geographic coordinates, while the second (June 26–July 11, 2024) carried out the floristic and phytosociological survey. Abbreviations: DBH – Diameter at Breast Height (cm) ; HC – Commercial Height (m); HT– Total Height (m) ; QS – Number of Stems; X and Y - Geographic coordinates.本数据集记录了莫桑比克波梅内保护区（Pomene Reserve）内开展的森林清查工作。本研究遵循Mueller-Dombois与Ellenberg（1974）提出的方法，采用固定样地法对乔灌植被开展定性与定量评估。 研究共设置60个20米×50米（单块面积1000平方米）的样地，在总面积200公顷的研究区域内，总采样面积达40000平方米（即4公顷），采样强度为3%。所有样地均通过卷尺与绳索完成地理定位与边界划定。 所有存活的植被个体（藤本植物除外）均进行编号，胸径（Diameter at Breast Height, DBH）≥10厘米的个体需记录其测量参数。植物区系采样分为两个阶段：第一阶段（2024年6月9日至13日）以标记采样点与记录地理坐标为核心任务，第二阶段（2024年6月26日至7月11日）则开展植物区系与植物社会学调查。 缩写说明：DBH——胸径（Diameter at Breast Height，厘米）；HC——商品材高度（米）；HT——总高度（米）；QS——茎秆数量；X、Y——地理坐标。
