Monitoring the impacts of bushfires on soils

Analyses of soil and vegetation samples collected by TERN on Kangaroo Island, South Australia, before and after the catastrophic 2019/20 bushfire are enabling scientists to track post-fire environmental recovery and ecosystem resilience. Here we highlight new research that is using TERN’s open-access soil samples to investigate the impacts of fire on soil and its ability to store and cycle carbon and nutrients.

Getting the measure of soil moisture in Australia

TERN’s new world-leading soil moisture information system provides nation-wide daily estimates of volumetric soil moisture at a 1km resolution and an index of how full (or wet) the top 90cm of soil is at a particular location and time. The system will help land managers better monitor drought, predict bushfires and floods and make highly informed management choices to improve agricultural productivity.

Top 3 things that control ecosystem behaviour revealed

The prestigious journal Nature has just published a substantial international study involving TERN Australia personnel and use of TERN data. The study identified three main factors controlling the function of terrestrial ecosystems and their predicted responses to climate change. The findings reveal that >70% of the variability within ecosystems is described by these three key characteristics.

Accessing disparate soil data

TERN’s SoilDataFederator makes multiple, disparate sources of soil data available ‘on the fly’ in consistent, easy to use formats. The SoilDataFederator significantly eases access to soil data created by different agencies and enhances Australia’s ability to use the data for understanding and overseeing managed and natural landscapes.

TERN digital soil maps the next best thing for locked-down students

Movement restrictions have forged stronger connections between TERN and university educators. Teaching academics no longer able to take their students on field excursions because of COVID-19 are finding value in using TERN’s data and data tools as a way to bring the Australian environment into their online teaching.

Soil microbiome and biodiversity implications – are we ignoring cost-effective proxies of biodiversity measures?

Environmental DNA (or eDNA) profiling is being used increasingly to analyse a range of substrates and historical samples, apparently even thin air, but what about soil? Join Prof. Andy Lowe as he investigates an important and cost-effective method of environmental DNA profiling.

How do we quantify Australia’s ecosystem services?

In this, our second popular science articles from TERN, Prof. Andy Lowe discusses the measures and metrics used to track the state, condition and trajectory of our ecosystem services. Read on to find out how TERN data streams can provide accurate estimates or supporting information to monitor the stocks and changes in critical ecosystem services now and into the future.

Actual evapotranspiration data for the entire Australian continent now available from TERN

High-resolution (30m), high-frequency (monthly), continuous (no gaps due to clouds) actual evapotranspiration data are now freely available for download from TERN. These world-leading satellite-derived data promote accurate water balance modelling for any catchment or groundwater system in Australia. The dynamics of water use from all vegetation communities, including ‘biodiversity hotspots’ such as groundwater dependent ecosystems, can be monitored through droughts and floods.
