Impact Of Fire On Geophyte Abundance, Diversity And Composition In The Jarrah Forests Of South-West Western Australia, Jeffry Cargill
Impact Of Fire On Geophyte Abundance, Diversity And Composition In The Jarrah Forests Of South-West Western Australia, Jeffry Cargill
Theses : Honours
Within fire-prone environments, such as the dry sclerophyll forests of south-west Western Australia, species morphology and distributions have established and maintained long-term dynamic relationships with fire regimes. These fire regimes can alter ecosystems, creating spatial and temporal changes in species composition, structure and fuel accumulation at both local and landscape scales. The cessation of Indigenous fire regimes and the establishment and expansion of a fire vulnerable European society produced the need for fire management strategies such as prescribed burning to be implemented to ensure protection of life, property and other values. Concurrent with these human-focused objectives has been the ever-increasing …
A Study Of The Effects Of Probait On Chuditch, Dasyurus Geoffroii, Within The Julimar Conservation Park With Notes On The General Ecology, Melissa York
Theses : Honours
Broad scale fox baiting programs have been underway in Western Australia since 1996 when the Western Shield fauna recovery program commenced with the aim of recovering many fauna species that are under threat of extinction. Until recently, effective fox control for fauna recovery has been achieved with dried meat baits impregnated with the poison 1080. The Department of Conservation and Land Management (CALM) has developed more readily available and cost effective sausage meat baits, termed Probait. As bait acceptability trials in the laboratory indicated a potential risk from Pro bait ingestion by chuditch (Dasyurus geoffroii), assessment of the likely risk …
Dryland Salinity In Western Australia: A Local Government Perspective, Paul Scalzi
Dryland Salinity In Western Australia: A Local Government Perspective, Paul Scalzi
Theses : Honours
This study evaluated local government's response to the problem of dryland salinity in the Western Australian Wheatbelt, and to what extent local government has the capacity to meet its statutory obligations. Salinity is a significant environmental problem that has the potential to have a marked effect on Western Australia's economy, environment and social fabric. The problem has been the focus of much Commonwealth and State attention, but the same level of involvement is not apparent in the institution of local government. This is also reflected in the paucity of published literature in the area of local government and salinity. Local …
