Fisheries research reports
The Western Australian Recreational Abalone Fishery (RAF) operates in shallow coastal waters along the metropolitan, south-west and south coasts. This hand collection fishery targets three species of abalone. Roe’s Abalone (Haliotis roei) inhabit nearshore reef complexes and are therefore generally collected while wading from the shore in accessible areas. This species is taken from the metropolitan, south-west and south coast regions. Greenlip Abalone (H. laevigata) and Brownlip Abalone (H. conicopora) are collected while wading (including snorkelling) and diving (using compressed air) and occur predominantly in the south coast region.

Building The Soil And The Community At Hollands Track Farm, Newdegate, Western Australia, Jamie Bowyer, Nick Kelly
Natural resources published reports
The Kelly family have been farming at Hollands Track Farm, about 18 km south-west of Newdegate, since 1965. They currently produce grains, beef, eggs and sheep. Long-term annual average rainfall is 350 mm. The Kellys were early adopters – in the 1990s – of the no-till farming system, which is now widely used in Western Australia. Around 2002 they sold the last of their sheep and moved to a continuous cropping program with increased fertiliser and chemical use. They were very good at this system, and it served them well. They really enjoy the challenge of growing good crops. Over …

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 …

Skeleton Weed In Western Australia / Management Guide, Department Of Primary Industries And Regional Development, Western Australia
Bulletins 4000 -
Skeleton weed is a declared plant which can reduce crop yields by competing for moisture and nutrients (mainly nitrogen).
This Management Guide has been designed to assist landholders and increase their capacity to manage and eradicate skeleton weed infestations on their properties and to prevent further spread within the State.
Without the coordinated program aimed at controlling spread, skeleton weed would now be much more abundant and widely established throughout the cereal growing areas.

‘Cockatoo Sands’ is a common name for the Cockatoo Sands family of soils (comprising red to yellowish-red sands, sandy earths, and loamy earths) that have formed from quartz sandstone colluviums in relatively isolated patches throughout the East Kimberley region of Western Australia and the Northern Territory. Cockatoo Sands are recognised as potentially suitable for irrigated agriculture because they are generally well drained and not subject to waterlogging or inundation. These characteristics allow them to be cultivated and prepared for planting various crops during the wet and dry seasons of northern Australia.
Expanding agricultural production onto the Cockatoo Sands around Kununurra …

Dryland salinity is a pervasive form of land degradation that has resulted from the clearing of about 17 M ha of native vegetation and the introduction of predominately cereal and pasture-based farming systems in the South-West of Western Australia. The change in water balance caused by clearing deep rooted endemic woodlands increased recharge and resulted in rising groundwater levels. After a lag period, the regolith began filling and groundwater approached the soil surface, evaporating and depositing stored salts in the rootzone of salt sensitive crops. Groundwater levels also rise and affect areas of remnant native vegetation, streams, wet-lands and rural …

Bulletins 4000 -
Subterranean clover (subclover, Trifolium subterraneum L.) is an annual pasture legume that provides high quality feed for livestock. It is estimated to be sown over 30 million hectares across southern Australia, with cultivars developed for the low, medium and high rainfall zones. Unfortunately, some older cultivars contain high levels of phytoestrogen which can affect the reproductive system of sheep and cause other health issues. This became a significant issue for sheep producers from the 1940s as new land was cleared and sheep grazed subclover-dominant pastures. There was a collection of livestock issues observed and these were grouped together under the …
