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).本数据集收录留尼旺岛低地热带森林与亚高山植被（Mare Longue样地及Piton de Caille样地）的调查数据，包含外来植物物种的出现率、盖度与入侵率，以及本土植物盖度。物种多度与多样性数值在草本、灌木及乔木三个植被层中完成量化测定。
