Review Of Toxicity Of Agricultural Chemicals And Implications For Aquatic Fauna Of The Keep River, Samanatha Reynolds, David Morgan Jun 2023

Review Of Toxicity Of Agricultural Chemicals And Implications For Aquatic Fauna Of The Keep River, Samanatha Reynolds, David Morgan

Natural resources commissioned reports

This report was compiled for the Western Australian Department of Primary Industries and Regional Development (DPIRD) as part of the National Water Grid Authority (NWGA) project entitled “Managing water quality to enable future irrigation development in the Kimberley Region, WA”. The purpose of this report is to review the toxicity of farm chemicals (herbicides and insecticides) used by farm operators in the Keep River catchment and their potential impacts on the aquatic species in the river, in particular those species that are listed under the Environment Protection and Biodiversity Conservation Act 1999. It is designed to complement the report entitled …

Using Landsat Satellite Imagery To Estimate Groundcover In The Grainbelt Of Western Australia, Justin Laycock, Nick Middleton, Karen Holmes Dec 2022

Using Landsat Satellite Imagery To Estimate Groundcover In The Grainbelt Of Western Australia, Justin Laycock, Nick Middleton, Karen Holmes

Resource management technical reports

Maintaining vegetative groundcover is an important component of sustainable agricultural systems and plays a critical function for soil and land conservation in Western Australia’s (WA) grainbelt (the south-west cropping region). This report describes how satellite imagery can be used to quantitatively and objectively estimate total vegetative groundcover, both in near real time and historically across large areas. We used the Landsat seasonal fractional groundcover products developed by the Joint Remote Sensing Research Program from the extensive archive of Landsat imagery. These products provide an estimate of the percentage of green vegetation, non-green vegetation and bare soil for each 30 m …


Ecological Risk Assessment For The Temperate Demersal Elasmobranch Resource, Maddison Watt, Matias Braccini, Kim Smith, Mathew Hourston Oct 2021

Ecological Risk Assessment For The Temperate Demersal Elasmobranch Resource, Maddison Watt, Matias Braccini, Kim Smith, Mathew Hourston

Fisheries research reports

In March 2021, the Department of Primary Industries and Regional Development convened an ecological risk assessment (ERA) of the fisheries that access the Temperate Demersal Elasmobranch Resource. The ERA considered the potential ecological impacts of the Temperate Demersal Gillnet and Demersal Longline Fisheries and recreational fishers who catch sharks and rays. 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.

2021 Assessment Of The Status Of The West Coast Demersal Scalefish Resource, David V. Fairclough, Sybrand Alex Hesp, Ainslie Denham, Emily A. Fisher, Rachel Marks, Karina L. Ryan, Elaine Lek, Rhys Allen, Brett M. Crisafulli

Fisheries research reports

A recovery program for the West Coast Demersal Scalefish Resource was introduced between late 2007 and early 2010, based on the maintenance of retained catches of demersal species (overall suite and each indicator species) by both the commercial and recreational sectors below 50% of the catches reported in 2005/06 (original catch recovery benchmarks).

Catch reductions were aimed at reducing exploitation levels (F, long-term fishing mortality of the key indicator species’ stocks) to below the threshold reference point (F = M, the natural mortality rate), which would then allow stocks to recover to above the …
