AusTraits, a curated plant trait database for the Australian flora

Area of Science:

• Botany
• Ecology
• Biodiversity Science

Background:

• Plant trait data is crucial for understanding ecological variation and biodiversity.
• Existing plant trait data is often fragmented across various sources, hindering large-scale ecological studies.
• A centralized, accessible database for Australian plant traits is needed.

Purpose of the Study:

• To introduce and describe the AusTraits database, a comprehensive compilation of plant trait data for the Australian flora.
• To provide information on version 3.0.2 of AusTraits, detailing its scope and content.
• To establish AusTraits as a model for global initiatives in plant trait data archiving and sharing.

Main Methods:

• Synthesized data from field campaigns, published literature, taxonomic monographs, and taxon descriptions.
• Curated and harmonized individual- and species-level plant trait measurements.
• Included contextual information on site properties and experimental conditions where available.

Main Results:

• AusTraits version 3.0.2 contains data for 997,808 trait-by-taxon combinations.
• The database covers 448 distinct plant traits across 28,640 taxa of Australian flora.
• Traits encompass physiological measures (e.g., water-use efficiency) and morphological attributes (e.g., seed mass).

Conclusions:

• AusTraits provides a valuable, accessible resource for ecological research in Australia.
• The database facilitates the study of ecological variation linked to plant traits.
• AusTraits serves as a template for developing similar national or regional plant trait databases worldwide.
