Standardising field-based assessment of invasion degree: a case study in two habitats of Reunion Island

The data comprise presence, cover and invasion rates of alien plant species and native plant cover in lowland tropical forest and subalpine vegetation (Mare Longue and Piton de Caille sites) in La Reunion. Abundance and diversity values are quantified among three vegetation strata (herbaceous, shrub and tree).本数据集涵盖留尼旺（La Reunion）境内Mare Longue与Piton de Caille两个采样点的低地热带森林及亚高山植被数据，包含外来植物物种（alien plant species）的存在率、盖度（cover）与入侵率（invasion rates），以及本土植物盖度（native plant cover）。本次研究在草本、灌木与乔木三个植被层（vegetation strata）中，对植物多度（abundance）与多样性（diversity）数值开展了量化测定。
