We’ve been working pretty hard over the past 6 months to incorporate all new freshwater stream segment and catchment data to better allow researchers to model freshwater species in the BCCVL. Details of this, plus more below:
The new things:
- Freshwater Data at 250m resolution.
We now have the Australian Stream and Catchment Environmental Data, which is a suite of environmental layers calculated based on the Australian Hydrological Geospatial Fabric (‘Geofabric’) network that represents stream segments and their catchments. Over 16 catchment or stream segment datasets (e.g. Climate, Substrate, Vegetation, Connectivity, Land Use etc.) there are 132 data layers ready for you to visualise and use in your models.
We’d like to thank the hard work of Janet Stein and her colleagues at the Australian National University (ANU) for developing this data and working with us to integrate it into the BCCVL. A big thanks also goes to Associate Professor Mark Kennard from Griffith University’s Australian Rivers Institute for consultation and advice in using this data in models.
Here is a few examples of some of the catchment layers, and how they look in the BCCVL:

Here is a quick example of an SDM, constrained to the Murray Darling Basin:
- To make it easier to find the data you are after, we’ve added dataset domain filters for terrestrial data and freshwater data.
- Citation metadata file downloadable for each experiment.
The improved things:
- New pre-defined constraint regions. You can now constrain the training of your model to added constraint boundaries from Drainage Division 1, Drainage Division 2, or River Region.
- Optimisation for configuring background point generation for Maxent.
- Multispecies data exported from ALA, now tagged as a multispecies dataset in BCCVL.
- Optimisation for rescaling of data with disparate resolutions.
- Migratory Modelling Experiments can now be selected for use in Climate Change Projection Experiments.
- We now give an estimated area for experiment constraints.
We’re a part of the EcoEd initiative
EcoEd provides cohesive training and skill development to university lecturers and researchers enabling them to combine theoretical concepts with real-world applications developed by three NCRIS facilities (ALA, BCCVL and TERN) into undergraduate and postgraduate curriculum.
ALA, BCCVL and TERN developed data and products are already being used by some of Australia’s most successful ecosystem scientists and most inspiring lecturers spread across all our universities and institutions.
The EcoEd program builds on these achievements, in providing the training required to further incorporate NCRIS-developed expertise and capabilities into Australia’s higher education and research sector. In doing so EcoEd is increasing the capacity of Australia’s research community to advance science and deliver outcomes that benefit the nation and underpin the sustainable use of our ecosystems. Moreover, it is enabling first-rate science education in Australia by supporting and nurturing our future scientists.
