Ecological Risk Assessment For The State-Wide Small Pelagic Scalefish Resource, S. Blazeski, J. Norriss, K. A. Smith, M. Hourston
Ecological Risk Assessment For The State-Wide Small Pelagic Scalefish Resource, S. Blazeski, J. Norriss, K. A. Smith, M. Hourston
Fisheries research reports
In July 2021, the Department of Primary Industries and Regional Development convened an ecological risk assessment (ERA) of the fisheries that access the State-wide Small Pelagic Scalefish Resource. The ERA considered the potential ecological impacts of the West Coast Purse Seine Fishery, South Coast Purse Seine Fishery, Purse Seine Development Zones and the recreational fishers who catch small pelagic scalefish. The assessment evaluated the impact of each fishing sector/method on all relevant retained and bycatch species, endangered, threatened and protected species, habitats and the broader environment.
Assessment Of Soil Sampling Equipment For Guiding Fertiliser Decisions, David Weaver, Robert Summers, David Rogers, Peta Richards, David Rowe
Assessment Of Soil Sampling Equipment For Guiding Fertiliser Decisions, David Weaver, Robert Summers, David Rogers, Peta Richards, David Rowe
Resource management technical reports
A range of methods, technologies and equipment are used to collect representative composite soil samples from paddocks. Once collected, soil samples are analysed for various parameters that provide evidence to guide fertiliser decisions. The sampling methods, technologies and equipment used must result in samples that consistently represent the parameter of interest.
Soil sampling technology and equipment has advanced from manual devices (such as pogo-stick-style foot-thrust core samplers [pogo]) to a variety of mechanised core-thrust samplers and augers that are fitted to vehicles or battery drills. Each device may function differently under different conditions, and each requires differing levels of human …
The Potential Of Remotely Sensed Vegetation Indices For Monitoring Pasture Condition, Pouria Ramzi, Karen Holmes
The Potential Of Remotely Sensed Vegetation Indices For Monitoring Pasture Condition, Pouria Ramzi, Karen Holmes
Resource management technical reports
The Department of Primary Industries and Regional Development (DPIRD) is developing an integrated monitoring system using remote sensing and on-ground measurements to track pasture condition across Western Australia’s pastoral region. We extended and adapted the methods developed in the Pastoral Lease Assessment Using Geospatial Analysis (PLAGA) project (Robinson et al. 2012), which combined remotely sensed vegetation indices (VIs) with on-ground pasture condition observations to assess the potential of using different vegetation indices in a statewide condition monitoring system.
There were 6 regions in WA’s pastoral rangelands with DPIRD on-ground condition traverse points: Kimberley and Broome, Pilbara, Yalgoo and Sandstone, Goldfields, …
Otoliths Of South-Western Australian Fish: A Photographic Catalogue, Chris Dowling, Kim Smith, Elain Lek, Joshua Brown
Otoliths Of South-Western Australian Fish: A Photographic Catalogue, Chris Dowling, Kim Smith, Elain Lek, Joshua Brown
Fisheries research reports
Due to the species-specific nature of otoliths and given they are often the only part of the fish preserved when fish die, otolith catalogues can be used in numerous applications, such as diet studies in fish eating animals, including pinnipeds, fish and sea birds; archaeological purposes such as reconstructing indigenous people’s diets from otoliths found in middens or evolutionary history of fish species by comparing fossilized otoliths. Given the unique mixture of subtropical and temperate fish, including many endemic species that occur off the southwest corner of WA having a catalogue for this area is extremely important for people working …
Fractured Rock Groundwater Wa Wheatbelt: Data And Methodology Review, Louise Hopgood, Richard Nixon
Fractured Rock Groundwater Wa Wheatbelt: Data And Methodology Review, Louise Hopgood, Richard Nixon
Natural resources commissioned reports
The Department of Primary Industries and Regional Development (DPIRD) in partnership with Water Corporation, working with Murdoch and Curtin universities, are looking at new options to improve farm water security in the wheatbelt of Western Australia.
Winter rainfall has declined since 2000 and dams, traditionally used for farm water supply, no longer provide sufficient or reliable water, especially after 1 to 2 below average years. Increasingly, groundwater supplies are being considered to supply farm needs, including those from fractured rock aquifers, with opportunities to desalinate to improve water quality.
This project undertook to review groundwater availability in fractured rock aquifers …

Resource Assessment Report Abrolhos Islands And Mid-West Trawl Managed Fishery Resource, Mervi Kangas, A Chandrapavan, Anne Wilkins, E. A. Fisher, S. Evans
WA Marine Stewardship Council report series
This document provides a cumulative description and assessment of the Abrolhos Islands and Mid-West Trawl Managed Fishery (AIMWTMF) and all of the fishing activities (i.e. fisheries / fishing sectors) affecting this resource in Western Australia (WA). This resource comprises of a single species of scallop, Ylistrum balloti which occurs in inshore waters to around 40 m depth at the Abrolhos Islands. This species is captured exclusively by demersal otter trawl gear in the West Coast Bioregion.
