Managing Granite Outcrops. Revegetation On Farms Information Kit, David Bicknell, Department Of Conservation And Land Management (Calm), The Royal Society Of Western Australia

Natural resources published reports

In Western Australia, granite outcrops rise from the surrounding countryside like an extensive island chain, stretching from the high rainfall south-west to the arid interior. They are extremely rich in biodiversity, which can change dramatically from outcrop to outcrop. They may contain relics of unique plant and animal populations and are very significant for nature conservation.

Granite outcrops can also be a major source of groundwater recharge within catchments, especially where the surrounding fringe and woodland vegetation has been cleared.

What is granite?

*Granite is an igneous rock consisting of large crystals of quartz, feldspar and mica or hornblende.

Report On Degradation In The Southern River / Wungong Catchment. Perth, Western Australia, Brian Lloyd

Natural resources published reports

A five day field survey of degradation in the Southern River/Wungong Catchment revealed several areas of concern. Key concerns are:

- Erosion and Sedimentation

Various forms of water erosion were present that cumulatively, would probably have a significant effect on the water quality of the Canning (and Swan) River. Much of the water erosion results from the installation and maintenance of infrastructure and developments, e.g. roads, subdivisions, stormwater drains etc. Reviewing standard practices, raising of awareness of consequences of erosion and training in urban erosion and sediment control techniques is recommended. Wind erosion is also an issue on the sands …

Groundwater Trends In The Agricultural Area Of Western Australia, R A. Nulsen

Resource management technical reports

In 1994 it was estimated that salinity affected more than 1.8 million ha of agricultural land in Western Australia (Ferdowsian et al. 1996). This area was predicted to expand to over three million ha by about 2020 and, if nothing is done to stem the expansion, to eventually affect some six million ha, or 30% of the agricultural land in the state. Damaging levels of salt accumulation in the root zone of both native and introduced plants can generally only occur when the groundwater levels are relatively cl te the variability of responses. Several depict episodic recharge (recharge as a …

Major Faults And The Development Of Dryland Salinity In The Western Wheatbelt Of Western Australia, C J. Clarke, Richard J. George, R W. Bell, Richard J. Hobbs

Natural Resources Research Articles

Dryland salinity poses a major threat to agricultural production in the wheatbelt of Western Australia and much time and effort is expended on understanding the mechanisms which cause it and on developing techniques to halt or reverse its development. Whilst the location of much dryland salinity can be explained by its topographic position, a significant proportion of it cannot. This study investigated the hypothesis that major faults in the Yilgarn Craton represented in aeromagnetic data by intense curvilinear lows explained the location of areas of dryland salinity not explained by topography. Moreover, the causal mechanisms that might underpin a spatial …

Western Australia Soil Acidity Research And Development Update 1998 : Time To Lime, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

Recent yield responses by canola where lime has been applied to acidic soils are very encouraging. Two sites have shown that the yield increase in canola after lime was applied in the previous year would have easily paid for the total cost of purchase, transport and application of the lime.

This work was carried out to demonstrate the increased options that are likely to be available once producers are treating or managing soil acidity. Canola is becoming increasingly important as a cash value crop and a break crop allowing wider rotations.

Growers are pushing the limits of canola’s tolerance to …
