Vegetation and trait data of the Houtman Abrolhos Islands, Australia

<p class="MsoNormal"><span>Dispersal and environmental filtering processes determine plant species colonization success on islands and can be identified by functional traits. However, the lack of synthesis about the varying methodological approaches in functional ecology hampers generalisation of filtering processes across island systems. Here, we provide island-plant data for 70 islands of the Houtman Abrolhos archipelago, Western Australia as well list species from their source pool. This data can be used to test the predictions made in the accompanying publication as well as for any other study requiring island-level species richness, species pool and trait (leaf area, seed mass, plant height) data.</span></p>
