AusTraits is a transformative database, containing measurements on the traits of Australia’s plant species, standardised from hundreds of disconnected primary sources. So far, data have been assembled from 139 distinct sources, describing more than 80 plant traits and over 19k species. A full list of sources is provided below. To handle the harmonising of diverse data sources, we use a reproducible workflow to implement the various changes required for each source to reformat it suitable for incorporation in AusTraits. Such changes include restructuring datasets, renaming variables, changing variable units, changing taxon names. While this repository contains the harmonised data, the raw data and code used to build the resource will also be made available, Contributors The project is jointly led by Dr Daniel Falster (University of New South Wales, Sydney) and Dr Rachael Gallagher (Macquarie University), with input from 127 contributors from over 59 institutions. The following people and institutions have have contributed to building this resource.

The ARDC is enabled by National Collaborative Research Investment Strategy (NCRIS). Accessing and use of data AusTraits will be released under an open source licence (CC-BY), enabling re-use by the community, once our paper describing the data resource becomes public (in 2020). In the meantime, access to the the data resource is restricted. A requirement of use is that users cite the AusTraits resource paper, which includes all contributors as co-authors: Citation pending In addition, we encourage users you to cite the original data sources, wherever possible. Contributing We envision AusTraits as an on-going collaborative community resource that: Increases our collective understanding the Australian flora; and Facilitates accumulating and sharing of trait data; Builds a sense of community among contributors and users; and Aspires to fully transparent and reproducible research of highest standard. As a community resource, we are very keen for people to contribute. Here are some of the ways you can contribute: Reporting Errors: If you notice a possible error in AusTraits, please post an issue on GitHub . Refining documentation: We welcome additions and edits that make using the existing data or adding new data easier for the community. Contributing new data: We gladly accept new data contributions to AusTraits.

Structure of AusTraits data The compiled AusTraits database has the following main components: austraits ├── traits ├── sites ├── methods ├── excluded_data ├── taxonomy ├── definitions ├── contributors └── build_info These elements include all the data and contextual information submitted with each contributed datasets. Full details on each of these components and columns therein are contained within the document Austraits_dictionary.html and within the file definitions.yml. Full details on all original sources used to generate this compilation and variables collected are available within the download.
