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.

The avifauna of Koobabbie, a 7 173 ha wheat and sheep property in the northern wheatbelt of Western Australia with 41.5% the property under remnant native vegetation, was monitored on a weekly basis from May 1987 to December 2011. Recorded during this period were 131 species, comprising 55 residents, seven regular visitors, 14 irregular visitors and 55 vagrants. Fifteen species declined over the 25 years, with one species being extirpated and two species increased. Two other species increased until early this century and then declined. The avifauna of Koobabbie was compared with that of the Northern Agricultural Catchment Council region, in the middle of which region the property is located. Koobabbie comprehensively represented the region’s avifauna and contributed significantly to conservation of the region’s avifauna. This study demonstrates the importance of continuous long-term datasets from a single locality. The need to set up a network of such monitoring sites over much of Australia in order to provide information for management of natural resources is discussed.

The decline of woodland birds that follows from habitat fragmentation, degradation and loss of connectivity is well reported in the literature. However, reports of immediate responses by birds to these events are scant. This study, in the eastern whealtbelt of Western Australia, detected that when half of a 10 ha remnant of Allocasuarina shrubland was chained (vegetation knocked over and largely killed), birds responded quickly; increaser species apparently benefited and decliner species became restricted to the remaining unchained remnant of shrubland. There was some correspondence between the trends in variety and/or abundance of arthropods with those of bird species richness. Two Near-threatened species, the White-browed Babbler Pomatostomus supercilious and the Crested Bellbird Oreoica gutturalis, were only detected in the non-chained part of the remnant. These findings clearly highlight the immediate ecological consequences of clearing of native vegetation, and highlight the importance of conserving even the smallest remaining fragments.

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.

Policies And Practices

For the most part, research and policymaking on urban gardening have focused on community gardens, whether in parks, vacant lots, or other public land. This emphasis, while important for many Midwestern cities, can obscure the significance of privately owned land such as front yard and back yard and their crucial connections with gardening on public land. In this case study, we examine how policies and practices related to gardening and the management of green space in two Midwestern cities exceed narrow visions of urban agriculture. The article explores the cultivation of vacant lot gardens and private yards as two modes of property in similar Midwestern contexts and argues that the management of green space is about more than urban agriculture. Instead, we show how urban gardening occurs across public/private property distinctions and involves a broader set of actors than those typically included in sustainability policies. Gardening also provides a key set of connections through which neighbors understand and practice sustainability in Midwestern cities.

78 Fordham Law Review 2799 (2010)The Internet is a semicommons. Private property in servers and network links coexists with a shared communications platform. This distinctive combination both explains the Internet's enormous success and illustrates some of its recurring problems.Building on Henry Smith's theory of the semicommons in the medieval open-field system, this essay explains how the dynamic interplay between private and common uses on the Internet enables it to facilitate worldwide sharing and collaboration without collapsing under the strain of misuse. It shows that key technical features of the Internet, such as its layering of protocols and the Web's division into distinct "sites," respond to the characteristic threats of strategic behavior in a semicommons. An extended case study of the Usenet distributed messaging system shows that not all semicommons on the Internet succeed; the continued success of the Internet depends on our ability to create strong online communities that can manage and defend the infrastructure on which they rely. Private and common both have essential roles to play in that task, a lesson recognized in David Post's and Jonathan Zittrain's recent books on the Internet.
