AusTraits: a curated plant trait database for the Australian flora

AusTraits is a transformative database, containing measurements on the traits of Australia's plant taxa, standardised from hundreds of disconnected primary sources. So far, data have been assembled from > 300 distinct sources, describing > 500 plant traits and > 34,000 taxa.

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 are also available on the project's GitHub repository, https://github.com/traitecoevo/austraits.build/.

Further information on the project is available at the project website austraits.org and in the associated publication (see below).

CONTRIBUTORS

The project is jointly led by Dr Daniel Falster (UNSW Sydney), Dr Rachael Gallagher (Western Sydney University), Dr Elizabeth Wenk (UNSW Sydney), and Dr Hervé Sauquet (Royal Botanic Gardens and Domain Trust Sydney), with input from > 300 contributors from over > 100 institutions (see full list above). The project was initiated by Dr Rachael Gallagher and Prof Ian Wright while at Macquarie University.

We are grateful to the following institutions for contributing data Australian National Botanic Garden, Brisbane Rainforest Action and Information Network, Kew Botanic Gardens, National Herbarium of NSW, Northern Territory Herbarium, Queensland Herbarium, Western Australian Herbarium, South Australian Herbarium, State Herbarium of South Australia, Tasmanian Herbarium, Department of Environment Land Water and Planning Victoria and the Royal Botanic Gardens Victoria.

AusTraits has been supported by investment from the Australian Research Data Commons (ARDC), via their "Transformative data collections" (https://doi.org/10.47486/TD044) and "Data Partnerships" (https://doi.org/10.47486/DP720, https://doi.org/10.47486/DP720A) programs; and grants from the Australian Research Council (FT160100113, DE170100208, FT100100910) and Macquarie University, The ARDC is enabled by National Collaborative Research Investment Strategy (NCRIS).

ACCESSING AND USE OF DATA

The compiled AusTraits database is released under an open source licence (CC-BY), enabling re-use by the community.

A requirement of use is that users cite the AusTraits resource paper, which includes all contributors as co-authors:

Falster, Gallagher et al (2021) AusTraits, a curated plant trait database for the Australian flora. Scientific Data 8: 254, https://doi.org/10.1038/s41597-021-01006-6

In addition, we encourage users you to cite the original data sources, wherever possible.

Note that under the license data may be redistributed, provided the attribution is maintained.

The downloads below provide the data in two formats:

• austraits-X.X.X.zip: data in plain text format (.csv, .bib, .yml files). Suitable for anyone, including those using Python.
• austraits-X.X.X.rds: data as compressed R object. Suitable for users of R (see below).

For R users, access and manipulation of data is assisted with the austraits R package. The package can both download data and provides examples and functions for running queries.

STRUCTURE OF AUSTRAITS

The compiled AusTraits database contains a series of relational tables and files. These elements include all the data, contextual information submitted with each contributed datasets, database schema, and trait definitions. The file dictionary.html provides the same information in textual format. Similar information is available at https://traitecoevo.github.io/traits.build-book/.

CONTRIBUTING

We envision AusTraits as an on-going collaborative community resource that:

1. Increases our collective understanding the Australian flora;
2. Facilitates accumulation and sharing of trait data;
3. Builds a sense of community among contributors and users; and
4. Aspires to fully transparent and reproducible research of the highest standard.

As a community resource, we are very keen for people to contribute. Assembly of the database is managed on GitHub at https://github.com/traitecoevo/austraits.build/.

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. See full instructions on how to contribute at https://github.com/traitecoevo/austraits.build/.
