For southeastern Australia, arrival of the First Fleet in 1788 raises similar issues in environmental history as the 1492 landing of Columbus in the Americas. But Anglo-Australian settlement is younger and better documented, both in terms of scientific proxy data and historical sources, which include data on stocking rates that generally were light. Environmental concerns were voiced early, and a lively debate continues both among professionals and the lay public, with Australian geographers playing a major academic and applied role. This article addresses environmental degradation often attributed to early pastoralism (and implicit clearance) in the Tablelands of New South Wales. Methods include: (1) comparison of well-reported travel itineraries of 1817–1833 with modern land cover and stream channels; (2) critical reviews of high-resolution pollen profiles and the issues of Aboriginal vs. Anglo-Australian fire ecology; and (3) identification of soil erosion and gullying both before and after Anglo-Australian intrusion. The results indicate that (a) land cover of the Tablelands is little changed since prior to Contact, although some species are less common, while invasive genera of legumes have modified the ground cover; (b) the charcoal trace in pollen profiles prior to Contact supports an ecological impact of regular Aboriginal burning and rare, catastrophic fires; and (c) most stream channels were already entrenched (“gullied”) well before 1840, with repeated cut-and-fill cycles during the late Holocene, but before Contact. Land impairment has not been a major problem on the Tablelands, although the last two centuries have experienced cumulative and complex environmental change. This unexpected empirical picture suggests that, until high-technology intervention, increasing periodicity/magnitude of extreme drought/precipitation events had been the overriding trend in interior New South Wales, perhaps reinforced by burning. There is no support for an apocalyptic model of colonial environmental history. [ABSTRACT FROM AUTHOR]

There is growing recognition at the global scale of the need to reverse, or at least mitigate, the damaging impacts of river regulation and overextraction of water. In New South Wales, the introduction of environmental flows, consolidated in the Water Management Act 2000, is taking place in the context of changing institutional structures, in particular the growth of adaptive management, integrated ecosystem-based perspectives, and increased community participation in the decision-making process. These developments presuppose that the information needs of river managers are understood. This article provides a classification of information needs for decision-making on environmental-flow allocations in New South Wales and then applies this classification to a case study of information use by a river-management committee on the Lachlan River. The discussion argues for the development of “adaptive information” to meet the challenge of integrating differing forms of information in striving to address the new demands of adaptive management.

Five boulder beaches located along the coast of New South Wales, Australia, were examined in order to determine if beaches composed of boulders differ in basic sedimentological structure and behavior from beaches composed of cobbles or pebbles. Each beach is aligned obliquely to the approaching waves and is composed of locally derived sediment. Investigation of beach-particle size, morphology, and roundness, along with foreshore slope, reveals consistent up-beach particle fining, positive size skewness, absence of shape zoning. absence of sphericity grading, and low foreshore slope. These characteristics of the five studied boulder beaches contrast markedly with the known characteristics of beaches composed of finer sediment, which suggests that boulders appear to form fundamentally distinct coastal sedimentary assemblages.
