1080 baiting information for pet owners

A must for pest control, but a risk to domestic pets. 1080 is the brand name given to the chemical compound sodium monofluoroacetate. It is the synthetically produced sodium salt of fluoroacetate and produced as a white powder which is odorless and tasteless to humans. 1080 has been developed for incorporating into various bait formulations for the control of vertebrate pests including wild dogs, foxes, feral cats, and feral pigs

Self-mustering yards for pastoral livestock management

Self-mustering yards (SMYs) are an important component of effective total grazing management in the pastoral regions. These yards are used to self-muster cattle, sheep and goats, as well as native browsers and feral animals as they enter the yards to access the water point

Managing herring in Western Australia

Following the recovery of the Australian herring stock in 2021, DPIRD formed the Australian Herring Future Management Working Group, made up of recreational and commercial representatives, to help us determine the best way forward for management of the species in WA

Challenges in modelling the impact of frost and heat stress on the yield of cool-season annual grain crops

Frost and heat events at critical growth stages could cause large yield losses. These temperature extremes are increasing in frequency and intensity due to climate change in many parts of the broadacre cropping regions globally, presenting challenges to food production. For cool-season grain-growing regions, where summers are already too hot, heat and frost risks can limit adaptation options. Capturing these stresses in crop models accurately is increasingly important for evaluating the timing, severity, and yield consequences of extreme events. However, most existing process-based models were not designed to simulate short-duration temperature extremes, limiting their ability to assess climate risk and inform adaptation to frost and heat. Yield responses to heat and frost are associated with pollen sterility, grain abortion, accelerated senescence, and grain filling. Six challenges limit current modelling approaches: (1) inadequate spatial and temporal resolution of extreme events, (2) threshold-based and non-linear crop responses, (3) interactions between phenology and management, (4) cumulative and interacting stress effects across development stages, (5) limited representation of genotype-specific sensitivities, and (6) reliance on daily temperature data. Addressing these challenges requires improved use of sub-daily climate data, incorporation of physiological damage mechanisms, and enhanced crop- and genotype-specific parameterisation. These developments are critical for improving crop yield predictions under extreme temperatures in the context of climate change

Western Australian Regional Development Trust Annual Report 2024-25

The Trust is an independent statutory advisory body to the Minister for Regional Development, established under the Royalties for Regions Act 2009 (Act). The functions of the Trust are to provide advice and make recommendations to the minister: for the purposes of sections 5(2) and 9(1) of the Act; and on any other matter relating to the operation of the Fund that is referred to it by the minister. In addition to its monitoring and advisory role, the Trust also works to engage and enhance relationships with key regional stakeholders and influencers to promote greater collaboration and innovation in the delivery of regional development in Western Australia.https://library.dpird.wa.gov.au/ar_wardt/1013/thumbnail.jp

WA Farming systems - initial findings

Agronomy needs to adapt to deal with large changes in WA farming systems. The benefit of diverse rotations are already showing impact after two years. Nitrogen remains a key driver of productivity, even following a legume crop or pasture

Fisheries Occasional Publication No. 149 - Economic Contribution of Wild-catch Fishing in Western Australia, 2024: Beyond Gross Value of Production

The wild-catch fishing industry plays a significant role in Western Australia’s economy, particularly in regional communities. This report summarises the economic contribution of the commercial wild-catch fishing sector in 2024, based on REMPLAN’s input-output (I-O) modelling methodology and DPIRD data and analysis. This report focuses on key economic indicators including total economic output, gross value added (GVA), and employment (FTEs). Key findings: Total Economic Output of the wild-catch fishing industry is $1.22 billion (total value of goods and services produced, including intermediate inputs) Gross Value Added (GVA) of the wild-catch fishing industry is$487 million (value of profit, wages, salaries and net taxes) Employment within the wild-catch fishing industry is 3,275 Full-Time Equivalents (FTEs )https://library.dpird.wa.gov.au/fr_fop/1091/thumbnail.jp

Recreational boat fishing participation varies across bioregional fisheries in Western Australia, with persistent patterns within fisheries and fisher typologies over time

Recreational fishing is popular worldwide and understanding variability in participation can inform policies that seek to improve sustain[1]ability of recreational fisheries and amenity for recreational fishers. However, not all recreational fishers are alike in their demographics or behaviours. This study explores temporal and spatial variability in licensed boat-based recreational fishing participation in Western Australia using data from a consistent survey design delivered 12 times from 2011 to 2024. Five fisher participation typologies were identified across four marine bioregions (North Coast, Gascoyne Coast, West Coast, and South Coast) and four fishery types (demersal, nearshore, pelagic, and invertebrate) with varied fisher characteristics (residence, age, gender, and avidity) associated with the likeli[1]hood of membership to each typology. West Coast casual fishers (32% of licensed fishers) were typically older, metropolitan residents that fished rarely or occasionally and were not associated with any fishery type, while West Coast specialist fishers (26%) were typi[1]cally younger, metropolitan residents and avid fishers that were associated with nearshore, invertebrate, and demersal fisheries. The remaining groups were typically younger, regional residents that fished in South Coast nearshore (16%), North Coast demersal (14%), and Gascoyne demersal (11%) fisheries. This study contributes to global issues regarding the impact of fisher heterogeneity on recre[1]ational fisheries, particularly in the context of increasing and ageing populations, which impacts fisher representation for monitoring and management, and perceived equity in resource allocation. Improved understanding of fisher typologies can be used to address management objectives and to develop appropriate education and communication strategies
