Salinity Action Plan : Wetland Vegetation Monitoring, 1998/1999, R. Gurner, G. Ogden, R. H. Froend
Salinity Action Plan : Wetland Vegetation Monitoring, 1998/1999, R. Gurner, G. Ogden, R. H. Froend
Research outputs pre 2011
This report represents the vegetation component of a project designed to provide on-going monitoring of wetland salinity and biological resources in wetlands of the agricultural zone of south-west Western Australia. Maintenance of wetland biological diversity in the agricultural zone is one of the major objectives of the Salinity Action Plan. Due to their low position in the landscape, wetlands are the habitat most affected by salinisation...

Wetland Vegetation Monitoring, 1998 Survey: Gnangara Wetlands, N. E. Pettit, R. H. Froend
Wetland Vegetation Monitoring, 1998 Survey: Gnangara Wetlands, N. E. Pettit, R. H. Froend
Research outputs pre 2011
Water regimes, both groundwater and surface water components dil'ectly effect distribution, health and species composition of wetland fringing vegetation. In the area of the northern Swan Coastal Plain overlying the Gnangara groundwater mound, wetland water levels and therefore the vegetation can be intimately connected to underlying groundwater levels. The Water Corporation (formerly Water Authority of Western Australia) has been drawing water from the Gnangara mound for domestic water supply for a number of years. The main objective of this study is to monitor the changes in the vegetation fringing these wetlands and to determine if this is related to changes …
The Distribution And Long-Term Change In Banksia Ilicifolia Communities On The Gnangara Mound, Ryan Gurner
The Distribution And Long-Term Change In Banksia Ilicifolia Communities On The Gnangara Mound, Ryan Gurner
Theses : Honours
The Gnangara Mound is a large shallow groundwater aquifer which occurs in the superficial formations bounded by the Swan River, Ellenbrook, Gingin Brook, Moore River and the Indian Ocean on the northern Swan Coastal Plain. To protect terrestrial vegetation on the Gnangara Mound. groundwater levels must be maintained to allow plants access to water which is required for their survival. In areas with a shallow depth to groundwater, studies have shown that groundwater drawdown (reduction of the water table by any processes or factors) has a high potential to impact on the vegetation (Havel. 1968: Aplin. 1976: Heddle. 1980a: Dodd …
Modelling The Effects Of Rehabilitation And Changed Agricultural Practices In A Saline-Affected Rural Catchment, M. K. Heller
Modelling The Effects Of Rehabilitation And Changed Agricultural Practices In A Saline-Affected Rural Catchment, M. K. Heller
Theses : Honours
The Bremer river catchment, on the South-coast of Western Australia, is typical of most river catchments in this region in that it has been seriously affected by sedimentation, salinisation and eutrophication brought on by the gradual dominance of agricultural land management practices. Vegetated rehabilitation and changed agricultural land management practices (ie minimum / zero tillage) have now been widely adopted throughout the catchment in response to these degradation issues. This study examined the potential impact minimum / zero tillage, vegetated rehabilitation and remnant vegetation could have on both a farm and catchment wide scale. A Geographical Information System was developed …
Rehabilitation Of A Salt Affected Wetland, Natalie Reeves
Rehabilitation Of A Salt Affected Wetland, Natalie Reeves
Theses : Honours
There exists an urgent need to rehabilitate salt-affected and degraded wetlands in the south-west of Western Australia, particularly in water resource catchments. Various rehabilitation techniques have been developed for such areas, which address the problem of integrating water catchment management and surrounding land use. Despite this, there has been limited success in restoring salt affected wetlands in the south west region of Western Australia. This project was established to develop a method for the rehabilitation of wetlands in the south west of Western Australia, using the western Coollangatta Farmland wetland as a case study. This site was chosen because of …
Lake Level Changes Within The Yellagonga Regional Park: A Historic Perspective, Jennifer A. Hamann
Lake Level Changes Within The Yellagonga Regional Park: A Historic Perspective, Jennifer A. Hamann
Theses : Honours
The Yellagonga Regional Park is located approximately 20 km north of Perth and 6km east of the coast, in the City of Wanneroo. The park is comprised of Lake Joondalup, Beenyup Swamp, Wallubuenup Swamp and Lake Goollelal, a largely directly-linked wetland system and their surrounds. The importance of wetlands within the Perth Metropolitan area is widely documented with only 20% of the pre-European settlement wetlands remaining. (Godfrey, 1988; Davis, 1988) By comparison wetlands in the Yellagonga Regional Park are relatively natural in their state. (LeProvost, 1987) The park is of significance due to its conservation value, providing a varied array …
