Burakin Focus Catchment Report, Mike Clarke
Burakin Focus Catchment Report, Mike Clarke
Natural resources published reports
The Burakin Focus Catchment Project was developed between farmers and Agriculture _ Western Australia. The project was designed to give farmers an understanding of the salinity processes occurring within the Catchment and suggestions on appropriate management.
Work began in the Catchment early in 1999 and was complete at the end of 2000. Intensive hydrological investigations formed the basis of the study, which was complemented by surface water control and revegetation strategies. Agronomic issues associated with sandplain soils were raised by the farmers at the initial meeting and this led to a soil survey to determine the pH status of the …

Farming Systems To Manage Salinity. Farmer Directed Research, Development And Extension. Research Results 2001, Richard Olive
Natural resources published reports
More and more of Western Australia's agnicultural lands are becoming saline. Currently it is estimated that about 18 milliion ha of land are affected to a greater or lesser degree by salinity causing production losses estimated at about $70 million a year.
Unless ways are found to halt and reverse the salinisation of land it is estimated that another 4.4 million ha could become saline over the next 50 years.
Grain growers and the Federal Government, through the Grains Research and Development Corporation (GRDC). are investing $12 4 million in R&D across Australia to develop productive solutions to the salinity …

Profiting From Adversity - Meeting The Challenge Of Salinity Through New Industry Development, Andrew Quinn, Tamara Law, Peter Rowe
Natural resources published reports
Salinity in the Wheatbelt of Western Australia is one of the most significant challenges facing the State's agricultural sector.
Efforts to manage the increasing effect of salt influenced and threatened farming land requires not only the implementation of new farming systems, but a new way of thinking and attitude to production more in tune with environmental and technological limitations.
While past environment lobby pressures have significantly focused on other production activities such as mining and forestry, the future is likely to see increased community interest in agricultural production systems.
Consumers World wide are becoming more environmentally sensitive, with global media …

Degradation In The Brockman River And Ellen Brook Catchments, Western Australia, Brian Lloyd
Degradation In The Brockman River And Ellen Brook Catchments, Western Australia, Brian Lloyd
Natural resources published reports
An eight day survey of degradation in the Ellen Brook and Brockman River catchments revealed several areas of concern. Key concerns are:
Erosion and sedimentation
Various forms of erosion were observed during the survey that would cumulatively have an effect on the quality of both the Ellen Brook and the Brockman Rivers, and ultimately the Swan River. Erosion resulted from many situations including landholder management, subdivision design and infrastructure maintenance. Raising awareness as to consequences of erosion and sedimentation, along with remedial techniques and best management practices is recommended for the various levels of stakeholders.

Mapping The Boulder City Wetlands Using A Global Positioning System (Gps) And A Geographic Information System (Gis), Jennifer Lea Bishop
UNLV Theses, Dissertations, Professional Papers, and Capstones
The Boulder City Wetlands is a constructed wetlands park located in Boulder City, Nevada, approximately 23 miles southeast of Las Vegas, Nevada. Currently, a baseline study of water quality is being conducted in the Boulder City Wetlands. This baseline study of the wetlands is an important step in understanding the development of the Boulder City Wetlands over time. As wastewater is eventually introduced into the existing community tap water running through the wetlands, it is expected that the nitrogen within the water will enhance the growth of vegetation in the surrounding area. Comparing the vegetation growth over time is only …

Bulletin 4396 - Byenup Hill Focus Catchment Benefit: Cost Analysis, Allan Herbert
Bulletins 4000 -
The main text of this document concentrates on the costs of the proposed strategies, and the on-farm financial benefits from forecast production changes - in particular the production differences between the 'do nothing' and 'with strategy' scenarios.
Members of the catchment group indicated however that their main focus was on preserving their capital base. Hence some discussion of the values of land lost to salt and premiums/discounts for 'landcared' vs 'unlandcared' land appears later in the report. Economics literature suggests that including changes in land values into these analyses is incorrect. It is argued that production differences are actually captured …
Bulletin 4359 - Soils Of The Swan Coastal Plain, Mike Bolland
Bulletin 4359 - Soils Of The Swan Coastal Plain, Mike Bolland
Bulletins 4000 -
Almost all the soils of the Swan coastal plain are formed by material deposited by sea, rivers and wind. The Yilgarn Block, east and south of the Scarp bordering the Swan Coastal Plain (Fig. 1), rose about 40 to 50 million years ago. This caused erosion of the block by rivers and streams, and the eroded material was either deposited onto the Swan Coastal Plain or washed into the sea. The eroded material formed new soils on the Plain.
Broadly there are two major types of soils on the Coastal Plain. The first is a series of dune system near …

Bulletin 4357 - Fertilisers For Pastures On Sandy Soils Of The Swan Coastal Plain, K. W. Angell
Bulletins 4000 -
When newly cleared for agriculture, the sandy soils of the Swan Coastal Plain were acutely deficient in phosphorus (P), nitrogen (N), and the trace elements copper ( Cu) and zinc (Zn) and sometimes molybdenum (Mo). Phosphorus deficiency was overcome by applying single superphosphate. Trace element deficiencies were overcome by adding Cu, Zn and Mo to superphosphate during manufacture, allowing P, Cu, Zn and Mo to be applied to the pasture in the one operation.
It was subsequently found that low sulphur (S) and potassium (K) were limiting production and persistence of subterranean clover-based pastures on the sandy soils of the …

Internal Temperature Of Douglas-Fir Buds Is Altered At Elevated Temperature, Martha E. Apple, Melissa S. Lucash, David M. Olszyk, David T. Tingey, Donald L. Phillips
Environmental Science and Management Faculty Publications and Presentations
Pseudotsuga menziesii (Douglas-fir) saplings were grown in sun-lit controlled environment chambers at ambient or elevated (4°C above ambient) temperature. We measured internal temperatures of vegetative buds with thermocouple probes and compared temperatures of normal buds and abnormal buds with loosened, rosetted outer scales in elevated temperature chambers. The abnormal buds had higher and earlier peak daily temperatures than normal buds. Elevated temperature may influence the internal temperature of buds and contribute to the development of abnormal, rosetted buds with loosened outer scales. Abnormal bud development may alter branching patterns and allometry of Douglas-fir trees subjected to climatic change.

Environmental Science and Management Faculty Publications and Presentations
Global climatic change as expressed by increased CO2 and temperature has the potential for dramatic effects on trees. To determine what its effects may be on Pacific Northwest forests, Douglas-fir (Pseudotsuga menziesii ) seedlings were grown in sun-lit controlled environment chambers at ambient or elevated (+4°C above ambient) temperature, and at ambient or elevated (+200 ppm above ambient) CO2. In 1995–1996 and 1996–1997, elevated CO2 had no effect on vegetative bud morphology, while the following unusual morphological characteristics were found with greater frequency at elevated temperature than at ambient: rosetted buds with reflexed and loosened outer …

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 …
