Description:
The spread of exotic willows (Salix spp.) in SE Australia, New Zealand and South Africa has provoked widespread debate in scientific, management and broader communities. In Australia, the extent of spread is unknown, but at least 30000 km of river frontage in Victoria are lined by willows. Management and research literature has identified the poor knowledge of willow impacts on Southern Hemisphere aquatic ecosystems. It has been speculated that the major distinction between deciduous willows and evergreen native vegetation will be the timing and quality of litterfall. This would have flow-on consequences for metabolic processes, stream biota and water quality at reach, stream and catchment scales. These two vegetation types were studied through the preparation of partial organic matter budgets for native and willow lined reaches in a central Victorian catchment. Organic matter inputs from litter, groundwater and gross primary production (GPP), organic matter standing crop . and respiratory output were quantified. Total inputs to willow and native reaches were similar (735 and 764 g ash free dry weight m•' yl, respectively). Inputs were dominated by litterfall (-60%) and there were no significant differences in annual litterfall between sites. GPP contributed -20% of total inputs and estimates suggested there were few significant differences in annual GPP, 24 h community respiration, ratio of GPP to community respiration (PIR) or net daily metabolism (NDM) between sites. Groundwater contributed -20% of total inputs with one third of the dissolved organic matter sourced during short flow paths through riparian sediments. Aggradation at willow sites appeared to increase the riparian flow path. Willow and native sites were heterotrophic and similarly dependent on allochthonous organic matter (P/R=O.2, NDM= -.6, and ratio of net primary production to total inputs -0.1). Willow research and management should also focus on retention capacity, including the recruitment and role of LWD and the structure and function of root systems. Removal of willows potentially facilitates native vegetation establishment but simultaneously decreases retention capacity and metabolic control by the canopy. Establishing native vegetation to fulfil broader biodiversity objectives whilst retaining willows for their potentially positive roles is a management challenge. In principle, establishing native species on the upland-sides of fringing willows and under willow canopies will direct succession toward a preferred outcome without destructive disturbance. Understanding of when benefits of willows outweigh their costs is a notable gap.

One of the difficulties in writing a regional history such as this thesis was the sensitivity surrounding the appropriate choice of terminology and spelling conventions. Conflicts have arisen between conforming to the standardisations of the History Discipline and a desire to accommodate the wishes of the indigenous communities in the geographical area of this study. The absence of trained linguists in the white community during the initial colonisation period has resulted in a considerable divergence of opinion over the nomenclature and spelling derivatives surrounding the indigenous people living in what is no w known as the Geelong-Ballarat region. The first white chroniclers referred to the Wathawurrung by a myriad of different names (over 100 different names were recorded by Clark for the people in this study area) including: Watowrong, Wartowrong, Wot o wrong, Watourong, Wodowrow . Throughout the text ofthis work 1 have applied the term Wathawurrung' to all indigenous groups in primary documents that involve the known language area of the Wathawurrung. Where there is some doubt as to which tribe is being referred to 1 have included other language groups that the writer ma y have also been referring to. " From Preface"

"Wallrock alteration associated with the world-class, vein-gold deposits of the Bendigo goldfield is more extensive than has been previously documented. Alteration is characterised by the development of a pervasive and extensive carbonate alteration halo, as well as a somewhat lesser sulphide alteration halo. Alteration features observed resulted from the passage of large volumes of hydrothermal fluids over a protracted period, with alteration features being centred on major structures that acted as the main fluid conduits. The location and history of the evolution of these structures was a dominant control on the location, intensity and extent of wallrock alteration developed."

"The study aims to document the attitudes and beliefs of a group of rural health and welfare professionals in the Central Highlands region of Victoria, to identify if theoretical frameworks of participants for the explanation of sexual assault reflect community attitudes based on traditional mythologies and misconceptions. The study also aims to highlight where specific training about sexual assault is required, based on needs of participants, and to recommend components for a future training program."

Description:
This thesis presents the Leigh community’s view of the impact of Hayden College on Leigh. The study establishes ‘community’ as the key aspect of this atypical school-community partnership in the context of research which shows that effective school-community partnerships are socially and economically beneficial for rural communities. The research question addresses the relationship between a particular college and a specific community. Hayden College was attracted to life in Leigh as a source of learning for its students and to community life in Leigh in particular. The research demonstrates that the school’s vision for its Leigh campus was one based on use of the town environs and interaction with the local people, and that the overarching concept of a community as a classroom entailed Hayden College becoming part of the Leigh community. The nature and quality of the relationship is explored by contrasting the school’s vision with the community’s view of Hayden’s membership of the Leigh community. Inquiry into the idea of a community as a classroom was approached by studying ‘community’ as an ideal concept. The thesis argues that the Hayden in Leigh development is a coincidence of educational and social ideals, clarifying what it means to be part of a community using conceptual analysis of qualitative data collected from the field. The theoretical stance and empirical material in this research show the way in which the power of the concept of community resides at the ideal level. The research finds that the nature of this school-community partnership is characterized by learning exchange and small town renewal but that a threat to the quality of the relationship between college and community is contained in disparate understandings of what constitutes community life. The implications of these findings for the post-Hayden Leigh community and rural schools and communities more generally are that the association of curriculum objectives with community development objectives depends on a healthy reciprocal relationship.

"This study focuses on poetry as evidence for the presence of a conceptual side to the nature of place. It utilises the poetry of the early European period in Australia to explore aspects of the manner in which concepts of place are transmitted through a community. It works through this poetry, seeking for rhetoric, for arguments about the nature of place and the values of particular aspects of place, rather than for particularly literary virtues of originality of language use"
