2017 Pre-wet REMP Sampling in the Fitzroy Basin

Hydrobiology’s Ecology and Biodiversity Management team have recently completed several receiving environment monitoring program (REMP) surveys across the Fitzroy Basin. There have been strong rainfalls throughout the region over the past two months, and many sites that have often been dry are now flowing. Hydrobiology have critically sampled and assessed aquatic habitat, stream flow, surface…

Southwestern Snake-necked Turtle

Our latest encounter with the Southwestern Snake-necked Turtles (Chelodina (Macrodiremys) colliei) as part of our recent surveys of the Avon River in Western Australia. The survey included sampling of water quality, macroinvertebrates and fish. The Southwestern Snake-necked turtle is endemic to the region and lives in permanent freshwater and seasonal swamps. Females will start laying their eggs in the coming…

Groundwater Dependent Ecosystem (GDE) analysis using remote imagery

Hydrobiology has been conducting multi-spectral imagery analysis to implement a range of recently developed tools available in the literature to mining projects across Australia and internationally. This has included assessing the rate of change of groundwater use indicators across the dry season, such as vegetation health (NDVI), landscape “wetness” (NDWI), actual Evapotranspiration (WIRADA/CMRSET data), groundwater…

Samarco’s Fundão Dam failure

Hydrobiology experts have been providing on-ground support to BHP on a regular basis since dam failure in late 2015. This has involved impact characterisation related to: aquatic ecology, marine and fresh water quality, and geomorphology. Support has involved regular site visits as well as remote data analysis in Australia. In conjunction with Brazilian scientists, Hydrobiology has…

DGT research at Hydrobiology

Hydrobiology is conducting a research project “Using an eco-toxicological approach to validate the Diffusion Gradients in Thin Film technique (DGT) for the measurement of bioavailable metal concentrations and applied to address the ANZECC and ARMCANZ (2000) framework test for bioavailable metal concentrations”. The research team has considerable experience in DGT technique, ecotoxicology, mine water chemistry,…

Assessing Brisbane’s waterways

Hydrobiology ecologists have teamed up with engineers from Engeny Water Management to assess the condition of Brisbane’s waterways. The project was undertaken for Brisbane City Council and involved walking and canoeing the vast majority of our beautiful waterways to make visual assessments of the natural habitats for plants and animals and locate any bed or…
