Conservation And Management

Woopenatty was a 7,293 ha wheat-sheep property in the Geraldton Sandplains biogeographic region of the northern wheatbelt of Western Australia. Data were collected on the presence of bird species seen on a weekly basis on the property from October 1987 until the end of 2002. A total of 133 species was recorded from the property during this period with 52 species of resident, 16 species of regular visitor, 15 species of irregular visitor and 50 vagrant species. The avifauna of the property was compared with records collated from 1904 from eight locations within a radius of 110 km of the property and from records within a radius of 50 km of the property from two Birds Australia atlases (1977– 1981 and 1997–2002). Seventy-four percent of the species, including many dependent on remnant native vegetation, recorded from the other localities were recorded on Woopenatty. The property was clearly of importance for conservation of the avifauna of the Geraldton Sandplains. This study illustrates the importance of publishing descriptions of regional biota in order to assess changes over time and the significance of remnant native vegetation on private property to conservation. Suggestions for setting priorities for conservation and management of such remnant native vegetation are made.

Blue Gum

In the mid-1990s commercial Tasmanian blue gum (Eucalyptus globulus) plantations were established in south-west Western Australia. We examined the extent of loss of potential nesting trees for an endangered obligate hollow-nesting cockatoo, Muir’s corella (Cacatua pastinator pastinator), resulting from establishment of these plantations during 1995–2004. Clearing of native vegetation was extensive in both Tonebridge (51%) and Frankland (76%) study sites. The proportion of land used for timber plantation increased significantly from 2.4% to 12.1% (Tonebridge) and 0.5% to 9% (Frankland) in the period 1995–2004. Plantations were predominantly established on already cleared farmland, but during the rapid development of plantations, large numbers of remnant paddock trees (mean = 56%) in cleared farmland were removed. Despite the loss of more than 50% of potential nesting habitat over an area of 376km2 within its current distribution, Muir’s corella continued to increase in numbers. However, there are concerns about delayed impacts of the clearing of potential nest trees we have observed, and consequences of further tree loss during future plantation harvesting. Evidence-based demonstration of biodiversity protection is increasingly needed to fulfil forest and plantation stewardship requirements, so greater care needs to be directed towards the management of extant remnant vegetation in paddocks.

Construction Activity

Australian construction productivity has grown slowly since 1985 and remains arguably stagnant. The importance of this study is therefore to examine several factors through to be drivers of construction productivity and to understand possible avenues for improvement. The drivers tested are research and development, apprentices, wage growth, unionisation and safety regulation. Expenditure on research and development and the number of apprentices were found to be drivers of productivity growth in Victoria, New South Wales and Western Australia. These findings are important because collectively, these three states account for a majority of construction activity in Australia.
